The troposphere contains 75–80 per cent of the mass of the #atmosphere. The height varies between 17km at the equator and 7.0km at the poles https://en.wikipedia.org/wiki/Atmosphere#Earth

What could possibly go wrong?

"About 10% of the particles floating around the stratosphere now come from the aerospace industry, and we don't know if this could impact the climate."

PLASTIC POLLUTION

We all know that plastic is directly killing our . But did you know that it’s polluting our too?

New research commissioned by and finally reveals the hidden climate cost of ’s plastics addiction, and the results are shocking.

In 2020, Australia’s plastics use produced more than 16 million metric tonnes of greenhouse gas emissions (GHG). That’s equivalent to 5.7 million cars on the road every year.

"De-orbiting #SpaceX #rockets are smashing temporary holes in the upper #atmosphere, creating bright blobs of light in the sky. Now, scientists have warned that these 'SpaceX auroras,' which look like glowing red orbs of light, could be causing unrecognized problems — though they are not a threat to the #environment or life on #Earth."

Here is the main practical reason that developed countries have been reluctant to pay up on #ClimateFinance, #LossAndDamage, and generally helping developing countires: we owe a lot.

As in, thousands of dollars for every citizen in developed countries. Every year. Until 2050.

This paper spells it out, by country:
"The #compensation system is based on the idea that the #atmosphere is a #commons, a natural resource for everyone to use equitably and sustainably."

Some photons a caught on my deck a while ago.

Moon halo, caused by specific conditions in the atmosphere where small ice particles create a rainbow circle around the Moon.

More often this is photographed with the sun as “sun dogs”.

In cased you missed this chart, it shows the predicted increase of and in the (black lines) compared to current observations (red & blue lines).

The prediction was made back in 1982 by ExxonMobil in private documents.

They knew since 1970s that would lead to with "dramatic environmental effects before the year 2050.”

Did they care ? Obviously no !

More media attention to the prospect that rapidly increasing human activity will drastically alter the space environment. "How could we possibly think that burning trash in our atmosphere 24/7 is going to be fine?"

Gigatons of #greenhouse gas are trapped under the #seafloor, and that’s a good thing. Around the coasts of the continents, where slopes sink down into the sea, tiny cages of ice trap #methane gas, preventing it from escaping and bubbling up into the #atmosphere.
