Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.

As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades: Graph of temperature as observed with significant warming, and simulated without added greenhouse gases and other anthropogentic changes, which shows no significant warming

How much each change to the atmosphere has warmed the world: IPCC AR6 Figure 2 - Thee bar charts: first chart: how much each gas has warmed the world.  About 1C of total warming.  Second chart:  about 1.5C of total warming from well-mixed greenhouse gases, offset by 0.4C of cooling from aerosols and negligible influence from changes to solar output, volcanoes, and internal variability.  Third chart: about 1.25C of warming from CO2, 0.5C from methane, and a bunch more in small quantities from other gases.  About 0.5C of cooling with large error bars from SO2.

Recommended actions to cut greenhouse gas emissions in the near future:

Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

You mean… the literal focus areas of the great green wall is turning green after almost 20 years of work?

Like, yeah storms are pushing in where maybe they shouldn’t but also this is shit multiple countries full of people have been working at since 2007.

Uh... This is the result of a land reclamation project that's been in place for more than 15 years and not at all the result in "a shift in the weather".

Not to mention that without the water retention infrastructure built over the years, increased rainfall wouldn’t be much good.

You just know this is going to change some minds about climate-change, but in a bad, pro-climate-change kind of way.

How much gold is under the antarctic ice sheet? let's find out

There isn’t much green in the Sahara Desert, but after an unusual influx of rain, the color can be seen from space creeping into parts of one of the driest places in the world.

Satellites recently captured plant life blooming in parts of the typically arid southern Sahara after storms moved there when they shouldn’t. It has also caused catastrophic flooding. And scientists say a world warming due to fossil fuel pollution is making both more likely.

How insane would it be if climate change pushed everyone back into Africa? That Africa ended up being the only remaining easily hospitable continent on the earth. From Africa we were born, and in Africa we will die.

I always thought this less sandy southern side of the desert was called the Sahel, not the Sahara? or Is the Sahel part of the Sahara?

The Sahel is the transition zone between the savannahs further south and the Sahara. In the image above; its where it gets noticeably less green but still distinct from the Sahara
