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.

Of note, the article is mostly about why extreme heat waves are more likely near the poles, with the current warming playing a limited role in this particular event:

The complete role of climate change is still under investigation, although the new study asserts that the warmer atmosphere didn’t play a large role boosting temperatures. The team ran a suite of computer models running scenarios that included increased greenhouse gas emissions vs. a world that did not. They found climate change only increased the heat wave by 2 degrees Celsius. By the end of the century, climate change could boost such a heat wave by an additional 5 to 6 degrees Celsius.

Holy hell this is terrifying. I pray and vote and spread the word to make this the peak year

Just wait till next year. Carbon emissions are staying steady so this trend should get worse. The amount the world naturally takes out isn't equivalent to what were putting in.

The absolute shit worst is that things are just going to worsen.. If the climate is hellish (hot, stormy, etc), then the likelihood of green means of transportation catching on are just hard. No one is going to ride a bike in 40 degrees celcius. Nor when it is stormy outside.
