Climate - truthful information about climate, related activism and politics.

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.

Arctic sea ice has been consistently shrinking since at least 1980. So have the Greenland and West Antarctic ice sheets. The East Antarctic ice sheet has by contrast been constantly growing since records began, which is probably where you got your factoid from. But this is due to local phenomena, such as the Antarctic ozone hole, increasing westerly wind strength and increasing snowfall. East Antarctica is one of the few regions which seems to have escaped the effects of climate change (so far).

There's almost no doubt that the world is warming overall due to human activity. The fossil fuel industry doesn't like this, so they put out propaganda to counter facts. Do your own research :).
