"both parties are exactly the same so it won't make a difference who wins"

okay so, fun fact: parties are a reflection of their voters

not their constituents, their voters.

why are republicans getting way more right-wing and fascist? bc far-right people have been turning out like crazy. they show up in primaries, in the general, they join organizations, call their reps, stage rallies and protests. they decide elections, they decide perceptions, so politicians cannot ignore them.

why are democrats historically pretty damn centrist? bc they are the only group that reliably shows up. candidates run based on who shows up, they govern based on who shows up, and if so many progressives and leftists keep sitting out elections in "protest", we're never going to get the candidates and governance we want. it's that simple.

so show up or shut up. because if you're not in that voting booth, you've already thrown away your best tool to actually fix things.

Every time I advocate for voting people are like "no you shouldn't vote! Read this literature, it'll totally change the way you view voting!" And every single time it's the same fucking "you shouldn't vote because both parties are exactly the same so it won't make a difference who wins" bullshit wrapped up in some fancy language

Yes.

@soursorrel nailed it: “photosynthesis is less efficient above 30°C, i've seen a lot of ppl get confused about that and think plants won't grow. the heat (dry heat primarily) just makes plants want to close their stomata to preserve water, but the stomata need to be open for photosynthesis for gas exchange. ...unless they're a c4 or cam plant (15% of plants) then it doesn't matter lol”

Above 30C the C3 plants, most crops, become different degrees of inefficient, all of which have direct impacts on production. What this means in reality is that though they, obviously, survive and are still be able to produce food, their efficiency at doing so decreases. On a single farm this may be a small decrease, over an entire state or even some smaller regions this adds up very quickly.

The more time during the day that C3 crops spend above 30C (86F) the less time they are actively photosynthesizing and the less energy (and carbs/sugars) they can make.

Less energy first manifests in smaller plant sizes and reduced rooting and later in fewer or smaller reproductive (food) bodies. If the plants are stressed during both stages, more loss.

Worse, most food crops are very specifically bred to work in rather specific conditions. Until we know what a farm’s new climate is (however long that takes) the more of a guessing game it will be for farmers and agronomists and the potential for lost productivity from having mis-matched cultivars will also reduce overall productivity.

In plant sciences (I’m an agronomist) we call anything that creates a non-productive response in plants a “stress” btw. Stresses compound, more stress = less productivity. Nothing is 100% in biological systems, there’s always weirdos, there are v few weirdos in modern agriculture though.

There’s also overnight temperatures, humidity, wind and rain patterns that are drastically changing and those too will cause plant stress on both well adapted plants and poorly matched annual cultivars.

I accidentally wrote a novel here, and then deleted it. I’m happy to talk more about this if anyone is interested.

If this post finds an arborist…

I’ve been seeing a lot of trees dying here in my pocket of MN - I’d love to how/if the increased temps are affecting established trees. I have a theory. Our trees are prob suffering from shifts in water cycle patterns too, but I’m v curious about the temp effects.

wait 30 degrees celsius is 86 degrees fahrenheit. is that guy saying you can't grow crops when it's hotter than 86 degrees
