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.

To anyone wondering, that is 69.3 degrees Fahrenheit (°F). So if it started from freezing it would make it "very hot", while if it were to start from lets say a perfect 70°F it would rise to ~140°F. And if it happened in the summertime when it was already 100, it would rise to 170°F - and how many people would even survive that? Maybe, if we had advanced warning and it were to only last a few hours - but what about things like crops & wildlife?

According to a recent poll, the number of Americans who outright deny climate change is down to just 15% of the population, but whether they "believe" in it or not may be indistinguishable from not believing - e.g. as this article discusses - since just like how they are "Pro-Life", the walk does not quite seem to match the talk.

To anyone feeling overwhelmed by all this: please don't be - there's only so much that any one person can do. Do what you can, and try to remain "aware", but this is bigger than all of us, and we will need to face it together, so you are not alone.:-)

I usually say sun screen, so sun cream sounded weird to me.
