Won't be long before we get a blue ocean event in Antarctica now.

What's a blue ocean event?

Ice caps are white, which reflects solar radiation. Once we get below 1 million square kilometers of icecaps left and the ocean is mostly blue, massive amounts of previously reflected solar radiation will instead be absorbed. This will cause rapid runaway heating and the release of huge amounts of methane from the sea floor and basically we're fucked.

This is a good explanation with diagrams and stuff.

Look this up for yourself with other sources though.

You'll want to find out how much ice coverage is left at the poles, how much we've lost this year so far, and the loss projections for if the next 5 years are as hot as 2023. Then look up what will happen to the earth with all the unreflected solar radiation we'll be absorbing without the ice caps.

Oh damn, we are gonna be screwed at this current rate ain't we. Also thanks for the explanation and the link.

No worries. We're screwed anyway though as even if by some magic technology we can stop global warming, we're still going to be out of fresh water and arable land soon.

Here's some fun links from the World Economic Forum and United Nations about this:
Global freshwater demand will exceed supply 40% by 2030 and 90% of global top soil and arable land is at risk of depletion by 2050.

Enjoy the last of the abundance while you can, it won't last much longer.

Near my place they are clearing all the tree cover and really using up the underground water tables. It's the same in many places as well. And then they stick few palm tress in the name of greenery.
