00:00What if fighting air pollution is actually making the planet hotter?
00:03It sounds crazy, but it's true.
00:05Scientists now say that by clearing the skies,
00:08we've accidentally made clouds less reflective,
00:10and that's heating up Earth faster than expected.
00:13See, when there's more smog in the air, clouds hold more tiny droplets,
00:17which makes them whiter and better at bouncing sunlight back into space.
00:21But as pollution drops, those clouds get darker and thinner, letting more heat in.
00:26Researchers studied two of the fastest warming ocean zones on Earth
00:30and found cloud reflectivity dropped by nearly 3% per decade.
00:34A whopping 70% of that change is caused by cutting pollution.
00:38The result? A dangerous climate paradox.
00:41We're saving lives by cleaning the air, but speeding up global warming in the process.
00:46So what's the fix?
00:47Scientists are now exploring marine cloud brightening,
00:50a method that sprays seawater into the sky to make clouds shinier without toxic pollution.
00:55But it's still risky, and could backfire.
00:58The race is on to cool the planet, without making things worse.
01:02When you're giving it an air pressure, you want them to try making them sleep sure.
