These types of comments are pointless. We are destroying the world. Ok. What’s the solution? All involve pain, but no one wants to talk about that . Tech isn’t going to solve it. For one, the kind of person on this site is contributing literally 10000x more to the issue than the worlds bottom, so we can start there. People love tech solutions, because then they don’t have to stop consuming and live modestly.

We could solve this problem in a few years with technology if we really wanted to.

I don't necessarily agree with GP's comment but they do have a valid point.

Everybody wants to solve the problem with technology. What if, the solution is just plain old hard work like planting trees, conservation, better recycling, better laws that help in saving ecosystem. But who would do that. So let's keep on creating problems with technology and then solve them with more technology.

Earth gets over 170,000 terawatts of solar energy every day—10,000 times more than humanity uses. Losing just a fraction of our cloud cover means a massive, invisible throttle is coming off the climate system. If this trend holds, we’re not just warming—we’re stepping on the gas.

What causes the shinkage of clouds? By writing "we’re stepping on the gas" you seem to imply that somehow humanity is causing this.

Interesting, the area I live in is expected to get more rain as climate change gets worse. So I would think we would have more cloud cover. But the article is about "reflective clouds". As I look out my window, I see dark clouds right now as opposed to white fluffy clouds. Will need to note the colors as time goes on for my fully non-scientific surveys :)

Dark clouds are only dark from below. Look at a satellite feed for comparison.

What technology specifically has caused the clouds to shrink?

I know this comment is just a list of fully-general counterarguments that can be dropped (with small modifications) on any scientific article, but you've invoked Poe's law. If this is parody, then it's an excellent parody; but if it's not, it's an almost maximally-uninsightful comment.

I'm not disagreeing, but we don't even need technology, all we need is the political will to truly stop subsidising fossil-based energy.

In the just over a minute it took me to read your comment and write this reply, the fossil industry received _another_ USD 14 Million: https://www.theguardian.com/environment/2021/oct/06/fossil-f...

terawatt is not an energy unit.

I like the use of watts/day instead of joules here because we have some intuition about watts. Earth must dissapate 170 exawatts per day of sunshine, in addition to letting off some amount of heat from the molten core. (Life has evolved on the edge of a knife, at the narrow balance point between enormous energies that cancel out just so . I often think that at the beach, looking out across the ocean, marveling that t…
