Super interesting read

tldr: turns out that the shitty oil that boats where burning where causing cloud cover that helped temporarily reduce global warming, after the ban on using that fuel the oceans have started to heat up

Quick thread, on how WE'VE BEEN ACCIDENTALLY GEOENGINEERING FOR DECADES...but then we stopped
SO2 actually (very temporarily) cools things down by seeding clouds and creating sulfuric acid aerosols. That's not, like, /good/, but by making more clouds (and also decreasing the size of droplets in clouds, and thus increasing their number) more sunlight is reflected to space.
One big source of SO2 is international shipping. Big ships use dirty fuels, dumping a ton of SO2 into the atmosphere, thus seeding clouds. You can actually see them from space...they're called "Ship Tracks."

Now, sulfur pollution is bad...it acidifies the rain which acidifies the ocean (which is already dealing with acidification). It can cause lung problems in humans and animals. So the UN's International Maritime Organization created a new rule to limit sulfur in ship fuels.
They started enforcing this in 2020...and we "lost the cooling effect from a fairly large volcanic eruption each year" according to FSU atmospheric scientist Michael Diamond.

Models show that the extra warming we've been seeing in the North Atlantic (which is a very busy area for shipping) can pretty much be /entirely attributed/ to the extra sunlight hitting the ocean (which has, this year, also been worsened by less dust blowing from the Sahara.)

Everything is fine...

the vlogbrothers covered it a few days ago. high sulfur fuel exhaust was seeding clouds leading to more sunlight reflected back into space. the upside is that we dont need to burn sulfur fuel. if you pump sea water thru misters into the air, the water evaporates and the salt crystals remain in the air seeding more clouds. the salt rain returns back the ocean where it came from.

There is some guy out there bitting his knuckles trying to figure out if this is solid fuck liberals cause doing the right thing had unintended negative consequences, or a solid fuck conservatives cause I guess humans absolutely can affect the climate...

"Damns libs fucked everything up, I'll bet if we put lead back in gasoline THE WAY GOD INTENDED it would fix climate change right away, but the stupid libs will never let that happen"

Scientists beam solar power to Earth from space for 1st time ever

The Space Solar Power Demonstrator's MAPLE experiment was able to wirelessly transfer collected solar power to receivers in space and direct energy to Earth.

there we go...all going to plan

Oh no, not again!

- I still remember the microwave beam missing the receiver and wiping out part of my city in Simcity 2000.
