#Greenland Ice Sheet

Please read

I've been protesting since i was two. I have memorised the chants, the speeches, the songs, the same arguments over and over and *over* again. I have signed over 500 petitions, i have attended over 150 marches, I have presented over 10 speeches personally. I don't remember when I learned about climate change because i always knew, so why didn't others?

I remember asking my Mother when i was around eight where she first learnt about it. When she was in year 8, back in 89-90. She said to me "I remember my teacher explaining it to us and thinking 'why isn't anyone doing anything'" She told me it's not that we don't have the answers, its we don't have the materials.

Now I know that is code for "the government is refusing to fund this" or "The government doesn't believe this is an issue" ect ect. Again and again, a new issue that needs to be solved or address or fixed before "we can focus on climate change"

Let me tell you ***You can not fight every battle*** But I try to. This latest "stunt" [Aliens aren't real] by the USA is yet another distraction from the biggest issue, The Atlantic ocean is facing a collapse.

Due to amount of cold water coming from the melted Greenland Ice sheets, It will cause the Atlantic meridional overturning circulation (AMOC) to collapse and shut down.

The last time this happened was around 15,000-14,500 years ago, at the end of the last ice age. It lead to a collapse of weather cycles, temperatures plunge and spike, ecosystems to collaspe.

If it collapses, La Niña could become the norm for Australia.

You can do something. I know because I've done something. So do it.

Scary News

Humanity is in danger of crossing the point of no return for five of Earth’s natural systems because of human-caused climate change, according to a new study from an international team of more than 200 researchers. The collapse of Greenland and West Antarctic ice sheets, widespread coral reef die-offs in warm water, disruption of the North Atlantic subpolar gyre circulation, and the abrupt thawing of permafrost regions are all in danger of being irreversibly crossed at 1.5 degrees Celsius of warming. Global temperatures have already risen between 1.1 and 1.3 degrees. “Tipping points in the Earth system pose threats of a magnitude never faced by humanity,” Tim Lenton said, lead author of the Global Tipping Points report. “They can trigger devastating domino effects, including the loss of whole ecosystems and capacity to grow staple crops, with societal impacts including mass displacement, political instability and financial collapse.” Lenton added that the report is a “tale of two future paths for humanity. We’ve basically left it too late for incremental action. Instead, we need to find and trigger what we’re calling some positive tipping points that accelerate action down an alternative pathway.”

This bit of information might be important to coastal communities. Ice cores drilled in ‘66 Sat in freezer until 2017 because the technology to analyze the thin sediment layers did not readily exist. Study of the ice cores indicates plant seeds and moss in the sediment; meaning there was no ice sheet at the time. This means this finding breaks with assumptions that the Greenland ice sheet had not completely melted in the geological recent past as once believed. So if Greenland HAD completely melted its ice sheet in the recent past (say 10,000-100,000 or so years) then Implications could be dramatic to costal cities, and island nations. We're already been seeing the impact since the mid 90's really and more so in the past 10 years.

If you were in Greenland last summer, that’s cool

TUESDAY, NOVEMBER 19, 2024

The 2024 melt season for the Greenland Ice Sheet ended with the second-lowest cumulative daily melt extent in this century, ranking twenty-eighth in the satellite record, which began in 1979. Summer air temperatures were generally low over the southern half of the island, with a persistent low-pressure system over Iceland driving cool northern winds across the ice sheet. A late summer heat wave along the northwestern ice sheet closed out the season. Meanwhile in the Southern Hemisphere, monitoring of Antarctica’s melt extent has begun, but daily maps are unavailable at this time. Updates will be provided as the season unfolds.

Overview of conditions

Greenland’s summer melt season featured many low daily melt extents (Figure 1a). The number of melt days was well below average along much of the western side of the ice sheet, by up to 15 days, but above average in the east-central region (up to 40 days above average near Kangertittivaq or Scoresby Sund in east Greenland). No melt occurred in the higher elevations of northern Greenland (above 2,500 meters or 8,200 feet) as has happened in several recent years.

The map on the right illustrates the difference from the 1981 to 2010 average melt days for the same period. The graph shows daily melt area from April 1 to October 31, 2024, with daily melt area for the past two years for comparison. A late September melt event is highlighted.

Conditions in context

Much of the Greenland Ice Sheet was cooler than average over the main summer months of June, July, and August (Figure 2a). Despite the above average number of melt days across the east-central ice sheet, overall conditions were 1 to 1.5 degrees Celsius (2 to 3 degrees Fahrenheit) below average, and 0.5 to 1.0 degrees Celsius (1 to 2 degrees Fahrenheit) below average for the three-month period prevailed over the southern part of the ice sheet. To the north, conditions were near-average to slightly above average by about 0.5 degree Celsius (1 degree Fahrenheit).

September’s last surge

September was a partial exception to the generally cool summer for Greenland in 2024, and a moderate spike in melt extent beginning on September 21 ended the season dramatically (Figure 1a, right). An intense high-pressure system in southern Baffin Bay drove warm air from central Canada onto the northwestern part of the ice sheet, causing extensive melting very late in the season. Temperatures soared to more than 10 degrees Celsius (18 degrees Fahrenheit) above average as the event began, and air temperatures in the following three days were as much as 18 degrees Celsius (32 degrees Fahrenheit) above average over the highest parts of the ice sheet.

Geologists discover rocks with the oldest evidence yet of Earth’s magnetic field

Geologists discover rocks with the oldest evidence yet of Earth’s magnetic field

Geologists at MIT and Oxford University have uncovered ancient rocks in Greenland that bear the oldest remnants of Earth’s early magnetic field.

The rocks appear to be exceptionally pristine, having preserved their properties for billions of years. The researchers determined that the rocks are about 3.7 billion years old and retain signatures of a magnetic field with a strength of at least 15 microtesla. The ancient field is similar in magnitude to the Earth’s magnetic field today.

The open-access findings, appearing today in the Journal of Geophysical Research, represent some of the earliest evidence of a magnetic field surrounding the Earth. The results potentially extend the age of the Earth’s magnetic field by hundreds of millions of years, and may shed light on the planet’s early conditions that helped life take hold.

Claire Nichols and colleagues stand on the outcrop of a banded iron formation containing the oldest records of Earth’s magnetic field. The Greenland ice sheet is in the background.

“The magnetic field is, in theory, one of the reasons we think Earth is really unique as a habitable planet,” says Claire Nichols, a former MIT postdoc who is now an associate professor of the geology of planetary processes at Oxford University. “It’s thought our magnetic field protects us from harmful radiation from space, and also helps us to have oceans and atmospheres that can be stable for long periods of time.”

Previous studies have shown evidence for a magnetic field on Earth that is at least 3.5 billion years old. The new study is extending the magnetic field’s lifetime by another 200 million years.

“That’s important because that’s the time when we think life was emerging,” says Benjamin Weiss, the Robert R. Shrock Professor of Planetary Sciences in MIT’s Department of Earth, Atmospheric and Planetary Sciences (EAPS). “If the Earth’s magnetic field was around a few hundred million years earlier, it could have played a critical role in making the planet habitable.”

Nichols and Weiss are co-authors of the new study, which also includes Craig Martin and Athena Eyster at MIT, Adam Maloof at Princeton University, and additional colleagues from institutions including Tufts University and the University of Colorado at Boulder.

A slow churn

Today, the Earth’s magnetic field is powered by its molten iron core, which slowly churns up electric currents in a self-generating “dynamo.” The resulting magnetic field extends out and around the planet like a protective bubble. Scientists suspect that, early in its evolution, the Earth was able to foster life, in part due to an early magnetic field that was strong enough to retain a life-sustaining atmosphere and simultaneously shield the planet from damaging solar radiation.

Exactly how early and robust this magnetic shield was is up for debate, though there has been evidence dating its existence to about 3.5 billion years ago.

“We wanted to see if we could extend this record back beyond 3.5 billion years and nail down how strong that early field was,” Nichols says.

In 2018, as a postdoc working in Weiss’ lab at the time, Nichols and her team set off on an expedition to the Isua Supracrustal Belt, a 20-mile stretch of exposed rock formations surrounded by towering ice sheets in the southwest of Greenland. There, scientists have discovered the oldest preserved rocks on Earth, which have been extensively studied in hopes of answering a slew of scientific questions about Earth’s ancient conditions.

For Nichols and Weiss, the objective was to find rocks that still held signatures of the Earth’s magnetic field when the rocks first formed. Rocks form through many millions of years, as grains of sediment and minerals accumulate and are progressively packed and buried under subsequent deposition over time. Any magnetic minerals such as iron-oxides that are in the deposits follow the pull of the Earth’s magnetic field as they form. This collective orientation, and the imprint of the magnetic field, are preserved in the rocks.

However, this preserved magnetic field can be scrambled and completely erased if the rocks subsequently undergo extreme thermal or aqueous events such as hydrothermal activity or plate tectonics that can pressurize and crush up these deposits. Determining the age of a magnetic field in ancient rocks has therefore been a highly contested area of study.

To get to rocks that were hopefully preserved and unaltered since their original deposition, the team sampled from rock formations in the Isua Supracrustal Belt, a remote location that was only accessible by helicopter.

“It’s about 150 kilometers away from the capital city, and you get helicoptered in, right up against the ice sheet,” Nichols says. “Here, you have the world’s oldest rocks essentially, surrounded by this dramatic expression of the ice age. It’s a really spectacular place.”

Dynamic history

The team returned to MIT with whole rock samples of banded iron formations — a rock type that appears as stripes of iron-rich and silica-rich rock. The iron-oxide minerals found in these rocks can act as tiny magnets that orient with any external magnetic field. Given their composition, the researchers suspect the rocks were originally formed in primordial oceans prior to the rise in atmospheric oxygen around 2.5 billion years ago.

“Back when there wasn’t oxygen in the atmosphere, iron didn’t oxidize so easily, so it was in solution in the oceans until it reached a critical concentration, when it precipitated out,” Nichols explains. “So, it’s basically a result of iron raining out of the oceans and depositing on the seafloor.”

“They’re very beautiful, weird rocks that don’t look like anything that forms on Earth today,” Weiss adds.

Previous studies had used uranium-lead dating to determine the age of the iron oxides in these rock samples. The ratio of uranium to lead (U-Pb) gives scientists an estimate of a rock’s age. This analysis found that some of the magnetized minerals were likely about 3.7 billion years old. The MIT team, in collaboration with researchers from Rensselaer Polytechnic Institute, showed in a paper published last year that the U-Pb age also dates the age of the magnetic record in these minerals.

The researchers then set out to determine whether the ancient rocks preserved magnetic field from that far back, and how strong that field might have been.

“The samples we think are best and have that very old signature, we then demagnetize in the lab, in steps. We apply a laboratory field that we know the strength of, and we remagnetize the rocks in steps, so you can compare the gradient of the demagnetization to the gradient of the lab magnetization. That gradient tells you how strong the ancient field was,” Nichols explains.

Through this careful process of remagnetization, the team concluded that the rocks likely harbored an ancient, 3.7-billion-year-old magnetic field, with a magnitude of at least 15 microtesla. Today, Earth’s magnetic field measures around 30 microtesla.

“It’s half the strength, but the same order of magnitude,” Nichols says. “The fact that it’s similar in strength as today’s field implies whatever is driving Earth’s magnetic field has not changed massively in power over billions of years.”

The team’s experiments also showed that the rocks retained the ancient field, despite having undergone two subsequent thermal events. Any extreme thermal event, such as a tectonic shake-up of the subsurface or hydrothermal eruptions, could potentially heat up and erase a rock’s magnetic field. But the team found that the iron in their samples likely oriented, then crystallized, 3.7 billion years ago, in some initial, extreme thermal event. Around 2.8 billion years ago, and then again at 1.5 billion years ago, the rocks may have been reheated, but not to the extreme temperatures that would have scrambled their magnetization.

“The rocks that the team has studied have experienced quite a bit during their long geological journey on our planet,” says Annique van der Boon, a planetary science researcher at the University of Oslo who was not involved in the study. “The authors have done a lot of work on constraining which geological events have affected the rocks at different times.” 

“The team have taken their time to deliver a very thorough study of these complex rocks, which do not give up their secrets easily,” says Andy Biggin, professor of geomagnetism at the University of Liverpool, who did not contribute to the study. “These new results tell us that the Earth’s magnetic field was alive and well 3.7 billion years ago. Knowing it was there and strong contributes a significant boundary constraint on the early Earth’s environment.”

The results also raise questions about how the ancient Earth could have powered such a robust magnetic field. While today’s field is powered by crystallization of the solid iron inner core, it’s thought that the inner core had not yet formed so early in the planet’s evolution.

“It seems like evidence for whatever was generating a magnetic field back then was a different power source from what we have today,” Weiss says. “And we care about Earth because there’s life here, but it’s also a touchstone for understanding other terrestrial planets. It suggests planets throughout the galaxy probably have lots of ways of powering a magnetic field, which is important for the question of habitability elsewhere.”

This research was supported, in part, by the Simons Foundation.

Did you know the “ice age” never completely finished?

By that I mean… you know the ice sheet that grinded Canada down to bedrock? The one that sat a mile high over Boston? The one that dug out the Great Lake basins? The one that pushed deep into North America, forming massive proglacial lakes and changing the courses of river systems?

That ice sheet still exists.

Sort of.

In Inuit territory, on the great island known as Qikiqtaaluk, you can lick the last, ancient icepop left from that continent-sized ice sheet that once smothered North America like a blanket.

Known as the Barnes Ice Cap, it’s the last fragment left of the mighty Laurentide Ice Sheet. And it’s melting FAST.

It will likely outlive me- but not by much. It’s like a 20,000-year-old ice cream cone, and we’ve dropped it on the hot pavement. In our rapidly warming world, it will likely be completely gone within a century or two.

Its contribution to global sea level rise won’t be particularly significant- it’s a rounding error compared to the Antarctic and Greenland ice sheets.

But to me, it’s like some kind of impossibly ancient alabaster tortoise;

a witness of unknown epochs of history;

critically endangered;

the last living of its kind;

doomed to perch up high on its mountain, drooling, panting, feverish, baked by the sun in a carbon blanket;

until it finally expires, leaving only bare rock and gravel for a grave:

no trace left of an ice age that covered a continent.

Excerpt from this EcoWatch story:

More than 40 scientists have written an open letter warning of a potential “tipping point” for the Atlantic Meridional Overturning Circulation (AMOC) in the Arctic.

The letter to the Nordic Council of Ministers encourages countries in the region to prevent global heating from causing AMOC’s collapse, which could lead to sudden changes in weather patterns and damage to ecosystems.

“Science increasingly confirms that the Arctic region is a ‘ground zero’ for tipping point risks and climate regulation across the planet. In this region, the Greenland Ice Sheet, the Barents sea ice, the boreal permafrost systems, the subpolar gyre deep-water formation and the Atlantic Meridional Overturning Circulation (AMOC) are all vulnerable to major, interconnected nonlinear changes,” the scientists said in the letter. “The AMOC, the dominant mechanism of northward heat transport in the North Atlantic, determines life conditions for all people in the Arctic region and beyond and is increasingly at risk of passing a tipping point.”

AMOC is an ocean current system that brings warm water to the North Atlantic, giving Europe its mild climate, reported Reuters.

AMOC’s collapse would raise sea levels in the Atlantic, make the Northern Hemisphere cooler, reduce precipitation in North America and Europe and change monsoon patterns in Africa and South America, the United Kingdom’s Met Office said, as reported by Reuters.

“If Britain and Ireland become like northern Norway, (that) has tremendous consequences. Our finding is that this is not a low probability,” said signatory of the letter professor Peter Ditlevsen of the University of Copenhagen, as Reuters reported. “This is not something you easily adapt to.”

The United States is experiencing scorching new levels of heat fueled by climate change this summer, with dozens of people dying in the West, millions sweating under heat advisories and nearly three-quarters of Americans saying the government must prioritize global warming.

But as the Republican Party opens its national convention in Milwaukee with a prime-time focus on energy on Monday night, the party has no plan to address climate change.

While many Republicans no longer deny the overwhelming scientific consensus that the planet is warming, party leaders do not see it as a problem that needs to be addressed.

“I don’t know that there is a Republican approach to climate change as an organizing issue,” said Thomas J. Pyle, president of the American Energy Alliance, a conservative research group focused on energy. “I don’t think President Trump sees reducing greenhouse gases, using the government to do so, as an imperative.”

When former President Donald J. Trump mentions climate change at all, it is mockingly.

“Can you imagine, this guy says global warming is the greatest threat to our country?” Mr. Trump said, referring to President Biden as he addressed a rally in Chesapeake, Va., last month, the hottest June in recorded history across the globe. “Global warming is fine. In fact, I heard it was going to be very warm today. It’s fine.”

He went on to dismiss the scientific evidence that melting ice sheets in Antarctica and Greenland are causing seas to rise, threatening coastal communities around the world. He said it would result in “more waterfront property, if you’re lucky enough to own.” And he lapsed into familiar rants against windmills and electric vehicles.

At the televised debate with Mr. Biden in June, Mr. Trump was asked if he would take any action as president to slow the climate crisis. “I want absolutely immaculate clean water and I want absolutely clean air, and we had it,” Mr. Trump responded, without answering the question.

Mr. Trump’s spokeswoman, Karoline Leavitt, later declined to clarify the former president’s position or discuss any actions he would take regarding climate change, saying only that he wants “energy dominance.”

The United States last year pumped more crude oil than any country in history and is now the world’s biggest exporter of natural gas.

A clear majority of Americans, 65 percent, wants the country to focus on increasing solar, wind and other renewable energy and not fossil fuels, according to a May survey by the Pew Research Center. But just 38 percent of Republicans surveyed said renewable energy should be prioritized, while 61 percent said the country should focus on developing more oil, gas and coal.

“Their No. 1 agenda is to continue producing fossil fuels,” said Andrew Dessler, a professor of atmospheric sciences and the director of the Texas Center for Climate Studies at Texas A&M University. “Once you understand their main goal is to entrench fossil fuels regardless of anything else, everything makes sense.”

The party platform, issued last week, makes no mention of climate change. Instead, it encourages more production of oil, gas and coal, the burning of which is dangerously driving up global temperatures. “We will DRILL, BABY, DRILL,” it says, referring to oil as “liquid gold.”

By contrast, Mr. Biden has taken the most aggressive action of any president to cut emissions from coal, oil and gas and encourage a transition to wind, solar and other carbon-free energy. He has directed every federal agency from the Agriculture Department to the Pentagon to consider how climate change is affecting their core missions.

If Mr. Biden has taken an all-of-government approach to fighting climate change, Mr. Trump and his allies would adopt the opposite: scrubbing “climate” from all federal functions and promoting fossil fuels.

Mr. Trump and his allies want to end federal subsidies for electric vehicles, battery development and the wind and solar industries, preferring instead to open up the Alaskan wilderness to oil drilling, encourage more offshore drilling and expand gas export terminals.

Project 2025, a lengthy manual filled with specific proposals for a next Republican administration, calls for erasing any mention of climate change across the government. While Mr. Trump has recently sought to distance himself from Project 2025, he has praised its architects at the Heritage Foundation, a conservative research organization, and much of the plan was written by people who were top advisers during his first term and could serve in prominent roles if he wins in November.

When pressed to discuss climate change, some Republicans say the country should produce more natural gas and sell it to other countries as a cleaner replacement for coal.

While natural gas produces less carbon dioxide than coal when burned, it remains one of the sources of the greenhouse gases that are driving climate change. Scientists say that countries must stop burning coal, oil and gas to keep global warming to relatively safe levels. Last year, at the United Nations climate summit in Dubai, United Arab Emirates, the United States and nearly 200 countries agreed to transition away from fossil fuels.

But if elected, Mr. Trump has indicated he would pull back from the global fight against climate change, as he did when he announced in 2017 that the United States would be the first and only country to withdraw from the Paris Agreement to limit greenhouse gas emissions. (The United States subsequently rejoined under Mr. Biden.)

And it’s possible he would go even further. Mr. Trump’s former aides said that if he wins in November, he would remove the country altogether from the United Nations Framework Convention on Climate Change, the international body that works on climate policy and created the 2015 Paris deal.

When it comes to international relations, Project 2025 calls for an end to spending federal funds to help the world’s poorest countries transition to wind, solar and other renewable energy.

The blueprint also calls for erasing climate change as a national security concern, despite research showing rising sea levels, extreme weather and other consequences of global temperature rise are destabilizing areas of the world, affecting migration and threatening American military installations.

Federal research into climate change would slow or disappear under Project 2025, which recommends dismantling the National Oceanic and Atmospheric Administration, which conducts some of the world’s leading climate research and is also responsible for weather forecasting and tracking the path of hurricanes and other storms.

NOAA, according to the authors of Project 2025, is “one of the main drivers of the climate change alarm industry and, as such, is harmful to future U.S. prosperity.” At the agency’s research operation, which include a network of research laboratories, an undersea research center, and several joint research institutes with universities, “the preponderance of its climate-change research should be disbanded,” the blueprint said.

Project 2025 also calls for the president to issue an executive order to “reshape” the program that convenes 13 federal agencies every four years to produce the National Climate Assessment, the country’s most authoritative analysis of climate knowledge. The report is required by Congress and details the impacts and risks of climate change to a wide range of sectors, including agriculture, health care and transportation. It is used by the public, researchers and officials around the country to inform decisions about strategies and spending.

Project 2025 also calls for the elimination of offices at the Department of Energy dedicated to developing wind, solar and other renewable energy.

Waleed Abdalati, a former NASA chief scientist who is now at the University of Colorado Boulder, said downgrading climate science would be a disservice to the nation. “That’s a loss of four years in pursuit of creative solutions,” he said.

As president, Mr. Trump tried to replace top officials with political appointees who denied the existence of climate change and put pressure on federal scientists to water down their conclusions. Scientists refused to change their findings and attempts by the Trump administration to bury climate research were also not successful.

“Thank God they didn’t know how to run a government,” Thomas Armstrong, who led the National Climate Assessment program under the Obama administration, said at the end of Mr. Trump’s presidency, adding, “It could have been a lot worse.”

Next time, they would know how to run the government, Mr. Trump’s former officials said. “The difference between the last time and this time is, Donald Trump was president for four years,” Mr. Pyle said. “He will be more prepared.”

The story of Greenland keeps getting greener—and scarier. A new study provides the first direct evidence that the center—not just the edges—of Greenland's ice sheet melted away in the recent geological past and the now-ice-covered island was then home to a green, tundra landscape. A team of scientists re-examined a few inches of sediment from the bottom of a two-mile-deep ice core extracted at the very center of Greenland in 1993—and held for 30 years in a Colorado storage facility. They were amazed to discover soil that contained willow wood, insect parts, fungi, and a poppy seed in pristine condition.

In 2023, the hottest year ever recorded, preliminary findings by an international team of researchers show the amount of carbon absorbed by land has temporarily collapsed. The final result was that forest, plants and soil – as a net category – absorbed almost no carbon.

There are warning signs at sea, too. Greenland’s glaciers and Arctic ice sheets are melting faster than expected, which is disrupting the Gulf Stream ocean current and slows the rate at which oceans absorb carbon. For the algae-eating zooplankton, melting sea ice is exposing them to more sunlight – a shift scientists say could keep them in the depths for longer, disrupting the vertical migration that stores carbon on the ocean floor.

A 4000-Year-Old Stone Box Grave Discovered in Norway

Archaeologists report an extremely important 4,000-year-old stone box grave has been unearthed in Western Norway, describing it as the most unique Stone Age find in Norway in the last 100 years.

This significant find, which archaeologists believe will provide information about how agriculture came to Western Norway, was discovered south of Vestkapp in Selje, Vestland. The grave is four meters long and over two meters wide.

It’s a sensational discovery and the most unique Stone Age finds in Norway in the last 100 years, says Morten Ramstad at the antiquities section at the University of Bergen.

The grave is a ‘hellekistegrave’, or stone box grave, a type of burial site that has previously only been found in Buskerud, Østfold, and Denmark, but never in Western Norway. Such a grave’s finding here is noteworthy and may help explain when agriculture, which first appeared in Norway circa 3950 BC, made its way to Western Norway.

The fact that this type of grave has not been previously found in Western Norway adds to the significance of the discovery.

Researchers may be able to ascertain the individuals’ ages, places of origin, and methods of transportation to Western Norway thanks to the exceptionally well-preserved human bone material discovered at the site.

Following the retreat of the great ice sheets, the first inhabitants migrated north into what is now Norway around 10,000 years ago. They were hunter-gatherers who lived off of seafood and game, particularly reindeer. The first agricultural settlements appeared around the Oslofjord between 5,000 and 4,000 BC. Between 1500 BC and 500 BC, agricultural settlements gradually spread throughout southern Norway, while residents north of Trndelag continued to hunt and fish.

The Neolithic period, beginning in 4000 BC, marked the beginning of agriculture in Norway. The Migration Period saw the establishment of the first chieftains and the construction of hilltop forts. Norwegians began to spread across the seas to the British Isles in the eighth century, and later to Iceland and Greenland. The Viking Age also saw the country’s unification.

The discovery of the 4,000-year-old grave in Western Norway adds to our understanding of the region’s agricultural history. The grave’s exceptionally well-preserved condition, as well as the human bone material discovered within it, could provide valuable data for researchers.

11,000 years of Greenland ice core temp and CO2 data shown

Because the climate naturally changes, these fools are trying to kill the global $US Petrodollar reserve, convince people it’s due to fossil fuel emissions and force the U.S. to completely replace our energy infrastructure and all of our fuel vehicles - DERP 😂😜

Image Source: Alley, R.B. 2000. The Younger Dryas cold interval as viewed from central Greenland. Quaternary Science Reviews

The upper panel shows the air temperature at the summit of the Greenland Ice Sheet, reconstructed by Alley (2000) from GISP2 ice core data. The time scale shows years before modern time. The rapid temperature rise to the left indicate the final part of the even more pronounced temperature increase following the last ice age. The temperature scale at the right hand side of the upper panel suggests a very approximate comparison with the global average temperature (see comment below). The GISP2 record ends around 1854, and the two graphs therefore ends here. There has since been an temperature increase to about the same level as during the Medieval Warm Period and to about 395 ppm for CO2. The small reddish bar in the lower right indicate the extension of the longest global temperature record (since 1850), based on meteorological observations (HadCRUT3). The lower panel shows the past atmospheric CO2 content, as found from the EPICA Dome C Ice Core in the Antarctic (Monnin et al. 2004). The Dome C atmospheric CO2 record ends in the year 1777.

You couldn't bare the look of the empty apartment after everything; every inch of the place had memories of you and Bucky, even the fucking table corner where Bucky had slammed into when chasing you around the area. 

You'd bumped into the Ancient One entirely by accident, and as one does when seeing actual magic for the first time, you'd thought you were black-out drunk and promptly nearly shat yourself when one of the things she'd been fighting came lunging at you. You're not sure what prompted her to take pity on you, but it was enough. The war had taken everything from you; what else did you have to lose?

“Are you crazy? Nepal?!” June had exclaimed, following you around your apartment as you packed what little you’d decided to take with you. 

“I can’t stay here, June…not without Bucky,” you told her.

"So your solution is to go someplace that you won't even tell me about, might I add, in the middle of the fucking mountains?! You've run away from problems before, but this," June pinched the bridge of her nose, "this takes the cake."

You paused, turning to June, and asked, “What do you want me to do, huh? Get hitched to some gal and have a miserable marriage thinking about my ex?!” Your voice raised to a yell before lowering, breath shaky, “I can’t stay here, June; I can’t pretend to be normal…I’m not like you or Pa; I never fit in here, remember?” You hadn’t ever spoken about the elephant in the room; June had always been better at shoving herself in a box; she’d been quiet about it all, a girlfriend here and there when Pa wasn’t looking, you’d tried, but you’d always been louder, less subtle. You smiled at her as best as you could, “See ya around, June.”

Kamar Taj was cold. Far from everything you knew, it was perfect. You hardly left Kamar Taj; even now, you kept the walls of the sanctum and ignored the world outside.

"I know you can hear me," Stephen's voice interrupts your thoughts; meditating in the courtyard had been a good idea in hindsight, but then he’d had rushed past from who knows where and spotted you.

"I can't hear you, Stephen."

"Yes, you can,” Stephen poked you, “you just replied to my statement."

You swat Stephen away with a flick of magic and return to your meditation, “Unless the world is ending, fuck off.”

"Remember how I saved your life a few months back, and you said you owe big time?" Stephen muses, and you groan in equal parts annoyance and defeat.

“Fine, what do you want?”

Bucky fucking hates the cold. If he could, he’d be back home, suffering through his nightmares under a warm blanket on the floor, but not today. Today, he gets to suffer in the middle of Greenland because Sam won at rock paper scissors, and A.I.M.’s new quantum processors need a colder climate to operate efficiently. All that doesn’t explain why Sam called Stephen Strange, but Bucky’s not going to complain as long as it gets him out of the cold quicker. A.I.M.’s base of operations was north of Summit Camp and buried into the ground; from the sky, it looked like part of the ice sheet and was barely visible even from where Bucky was scoping from.

The air turns warm for a moment as the familiar sound of magic tearing open a portal can be heard behind Bucky; the super soldier sighs in relief at the sound of Strange´s arrival, “Took you long enough, Strange,” Bucky turns to greet the sorcerer, and is instead left wide-eyed at the sight of you. You’ve hardly aged a day, dressed just as meticulously as Strange - an attire of pale colors to match the frozen landscape, ink-stained beautifully like a pattern across your skin, dog tags around your neck, and so many other details Bucky could hardly capture as his mind tried to process that you were alive. You blink a few times, expression soft and painful; your own eyes drift over him, widening at the sight of his metal arm, ‘What happened to you?’ he can see the question in your gaze. 

“Doll?” Bucky’s voice is strangled, weak; he’s almost prepared for all of this to be some sleep-deprived hallucination.

“Buck?” You say simultaneously, reaching out but drawing back when the sensors pick up movement from the A.I.M. facility. You turn your attention to the mission. Bucky stammers something, and you reply, “After the mission.” You tell him, and he holds you to that, catching you before you can run off; he drags you to Nuuk, and you spend a few minutes before your first proper conversation in years in uncertain silence. 

“You…uh…you look nice.” Bucky compliments.

“So do you, I…how are you here, Bucky? I thought,” you stammer, “They told me you died. You fell off a train.”

Bucky wrings his hands, his jaw clenched; the words don’t come easy to him. He runs through sentence after sentence in his mind, eyes darting from you to his hands; what does he say? ‘I was tortured for years and had my mind fucked up so bad I can barely remember my name some days’ or ‘I became a tool for HYDRA, I killed people’? Neither one was an easy answer. How could he even begin to explain his time with HYDRA?

“I…I wasn’t in a good place,” he finally replies, “I can barely remember some of it; I don’t think I want to.” Bucky doesn’t elaborate; he doubts he could without breaking down. “What about you?”

“Me? Oh well, I thought a change of scenery would be nice,” You try to smile, but it doesn’t reach your eyes, "playing hero now, huh?"

Bucky shrugged, "Suppose so, you some wizard now?"

"Yeah, and a pretty good one too." You laugh, feeling a little lighter; you briefly glance at his arm and think of reaching out to touch it; the smooth metal looks inviting, "Nice arm."

Bucky snorted, half baffled by the comment and unsure how to reply without self-deprecation, "Thanks?"

"Take the compliment, Buck," you teased, "you still owe me a home in the woods and a trip around the world, remember?" He doesn't, but he'll take your word for it and build you whatever you want, go anywhere, just as long as it's with you.

In 2023, the hottest year ever recorded, preliminary findings by an international team of researchers show the amount of carbon absorbed by land has temporarily collapsed. The final result was that forest, plants and soil – as a net category – absorbed almost no carbon. There are warning signs at sea, too. Greenland’s glaciers and Arctic ice sheets are melting faster than expected, which is disrupting the Gulf Stream ocean current and slows the rate at which oceans absorb carbon. For the algae-eating zooplankton, melting sea ice is exposing them to more sunlight – a shift scientists say could keep them in the depths for longer, disrupting the vertical migration that stores carbon on the ocean floor. “We’re seeing cracks in the resilience of the Earth’s systems. We’re seeing massive cracks on land – terrestrial ecosystems are losing their carbon store and carbon uptake capacity, but the oceans are also showing signs of instability,” Johan Rockström, director of the Potsdam Institute for Climate Impact Research, told an event at New York Climate Week in September. “Nature has so far balanced our abuse. This is coming to an end,” he said.

“None of these models have factored in losses like extreme factors which have been observed, such as the wildfires in Canada last year that amounted to six months of US fossil emissions. Two years before, we wrote a paper that found that Siberia also lost the same amount of carbon,” says Ciais. “Another process which is absent from the climate models is the basic fact that trees die from drought. This is observed and none of the models have drought-induced mortality in their representation of the land sink,” he says. “The fact that the models are lacking these factors probably makes them too optimistic.”

“We shouldn’t rely on natural forests to do the job. We really, really have to tackle the big issue: fossil fuel emissions across all sectors,” says Prof Pierre Friedlingstein of Exeter University, who oversees the annual Global Carbon Budget calculations. “We can’t just assume that we have forests and the forest will remove some CO2, because it’s not going to work in the long term.”

When I first heard about this I saw that scientists didn't know if this would be temporary or not, this article states it "could" be temporary so... well...
