Freezing rivers would be a sign of global coldness not warming Haardrada??!! Niagara partially froze over in 2022, although last fully frozen falls on record was 1848, I believe. I think global warming of seas is quite well documented. Yes it might have happened previously without humankind input but us humans are certainly lending a big hand to process in last 250 years. CarlL the nihilist Hi CarlL, I found out we're not alone! Some people (as clever as you and me, we might say) have already begun with the project to save the planet by albedo management. It is called MEER (Mirrors for Earth's Energy Balancing) and can be found here. I see a light at the end of the tunnel... ...and lots of mirrors on the roofs. Cheers, Brian

A little late, but still a fun fact, considering the madness of it: In Germany, you would not be allowed to paint walls and (especially!) roofs white in most cases. Most street development plans have very detailed ideas about what you are allowed to do with your house and the wrong hue of red for your roof's shingles may get you into serious trouble.

And yet, no problem without a solution: scientists developed so-called Enhanced Color-preserving Radiative Cooling (ECRC). Take a look at this text. And something in german.

Hello all
We feel we are important, we are not, we are speaks of dust in the corner of a room so to speak.
One good volcanic eruption will have a bigger effect than mankind.
Consider Krakatoa, the effect of the dust caused lovely sunsets for a year afterwards, in England, it was caught by an artist. For a period the level of the sea in the English channel was raised, it was recorded at the time. Look at the plants the Romans grew in England, then look at where those plants grow now.
Until people are prepared to give up what they want, and learn to act intelligently, we will always have problems. Consider the recent flooding in England, there is an old medieval saying that roughly runs "never live by a great river, great bell or great landlord". We ignore it all the time.

David Constable Yep, you're right, we have to act intelligently, and I'm absolutely sure of the fact: few men make the difference. If they go ahead, some are sure to follow, and then more and more...

Now there's something quite interesting about cooling colours on youtube. This guy shows how cheap and easy it is to make pigments that reflect NIR heat into space.

Another encouraging story: white hydrogen might save the world. Use it to produce energy without any carbondioxide as byproduct. Use it in the Fischer-Tropsch-synthesis to produce climate neutral fuels. And the funniest things about it: the earth produces hydrogen continually in the deeper layers. And if you only drill a hole deep enough the hydrogen comes up automatically! So the costs are even now quite low: 1 $ per kg.
