Above warmer oceans, clouds evaporate faster,
exposing the dark ocean to direct sunlight, leading to even more warming.
And decreased air pollution from ships
reduces cloud droplets and their size:

Maritime Stratocumulus Wolken verschwinden, das ist schlecht, denn sie wirken kühlend. Ist der Ozean wärmer lösen sich die Wolken weiter auf und der Ozean erwärmt sich. Eine gefährliche Kettenreaktion, die sich global auswirkt.

clouds and aerosols can be measured with European satellite

🌍NASA data shows that global cloud cover decreased by 0.5%-point in 20 years!⛅️
The global cloud area fraction is from NASA's Clouds and the Earth’s Radiant Energy System (CERES) project, which provides satellite-based observations of Earth’s radiation budget and clouds

Inside a cloud it starts raining but the
droplets are so tiny that they evaporates even before they reach the ground.
= no rain with less aerosols
( big rain droplets required to rain down to ground )

nitrogen pollution. That comes in two forms.
Nitrate from cars and fossil fuel burning and
ammonia from farming activities from urine and dung emitting
...
So the site is losing CO2 to the atmosphere.

Edward Graham
acid rain 1979 was ph 1.5 (acid like old car battery)
few aerosols are good a lot SO2 is pollution
/zu viele in die Atmosphäre gelangen
Sie werden zu Schadstoffen und überlasten den natürlichen Kreislauf, was zu saurem Regen führen kann.

Dr Raymond Shaw:
cloud over the Arctic the cloud almost doesn't exist.-cold no water vapor in the air.
But it turns out that clouds themselves influence the aerosol particles.
Clouds can consume the aerosol particles.

Dr Raymond Shaw -Michigan state university
clouds are water and something for that water to condense: aerosols.
Without the aerosols, clouds simply wouldn't exist on the earth.

Earth's albedo is continuing to collapse, resulting in rapidly increasing solar radiation absorbed ... but, fortunately, longwave radiation to space is following it up (the *opposite* of what you'd simplistically expect from increasing GHG

What's going on? huge change.
cloudiness is declining but that isn't enough to explain. Clouds also seem to be becoming *less bright*. And, for whatever reason, cloudy areas are also radiating more longwave to space.

One main reason for the difference is clouds. Just changing the ice module for clouds can change surface temperatures up to ~3°C (2)

2) high climate sensitivity 4.5°C implies a large contribution from
amplifying feedbacks:
water vapor, #FB2
surface albedo (sea ice/snow) and
clouds. #FB7

aerosols are condensation nuclei
More nuclei yield more cloud particles and brighter clouds
More aerosols also increase cloud cover
clouds are climate feedback #FB7

climate change will cause air over the eastern Pacific Ocean to warm faster than the west,
weakening an important branch of the large-scale circulation.
But for the past few decades, the eastern Pacific has actually been cooling

Norman Loeb thinks IMO2020 pollution declines has an important role in the cloud changes, especially in the Northern Hemisphere.

#8C17.8 #FB7 cloud feedback.
80% of the overall reflectivity changes in these regions resulted from shrinking clouds.
( my opinion
IMO2020 causes less SO2 aerosols
-> bigger water-droplets
->lower reflection area
= lower albedo
)

The cloud coverage is falling 0.15% per year.
couple percentage points may not sound important.
“But if you calculate these trends, it’s massive,” he says.
“This would indicate a cloud feedback that’s off the charts.”
