What is geoscience?

Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

I thought the ozone hole was supposed to be shrinking?

[–] Deceptichum@kbin.social 16 points 1 year ago

China.

We show that emissions from eastern mainland China are 7.0 ± 3.0 (±1 standard deviation) gigagrams per year higher in 2014–2017 than in 2008–2012, and that the increase in emissions arises primarily around the northeastern provinces of Shandong and Hebei. This increase accounts for a substantial fraction (at least 40 to 60 per cent) of the global rise in CFC-11 emissions. We find no evidence for a significant increase in CFC-11 emissions from any other eastern Asian countries or other regions of the world where there are available data for the detection of regional emissions.

I thought it was gone

I was told it was fixed. WTF?

Like the ozone thing was the last time humanity came together and fixed a problem instead saying it was a LiBrUl oZone hole.

Yeah, that’s what I heard too. And it was because of CFC’s and wasn’t related to climate change. Once CFCs were outlawed, I heard the hole in the ozone was fixing itself (and ultimately fixed).

That was the hole above California. This hole is above Antarctica, apparently caused by emissions drifting from China.
