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.

It is important to note that high temperature increase will accelerate when feedback loops kick into action. Tim Lenton says that the right metaphor is not a chair falling over, as in, once we hit temperature X, then we doomed. If the chair falling over is used, then metaphorically it is falling through honey, the higher the temperature, the faster the fall and less time for finding solutions. Key takeaway: Never give up, always try to reduce emissions as they all have an impact on how much time we have.

when feedback loops kick into action

The feedback loop is already in action, that's the point they were trying to make. Polar ice caps are already in a runaway melt loop. We will not save them.

There is no situation in which we get climate change under control to a point where the entire earth's ecosphere doesn't change drastically in the next 100 years. That ship sailed ages ago. We can try to staunch the bleeding, and I think we should in any way that we can, but there is no realistic future in which we "recover" from this.
