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.

The planet is warming so fast, it could cross a key climate limit [1.5°C above the late 1800s] in 2024 (wapo.st)

New research shows the planet on track to top a warming benchmark next year. Many at COP28 remain hopeful the world can avoid that threshold.

Here is where the article tells us what to expect probably from next year forward:

A surge of global temperatures that began this summer provided an initial picture of how a planet 1.5 degrees hotter will look: Unprecedented heat at the limits of human survival. Antarctic sea ice astonishingly far below its record minimum. Devastating floods, fires and other weather extremes that have been linked to climate change.

This is where we stand:

The team of scientists projected that the temperature of the planet could consistently exceed the 1.5C threshold within seven years if emission levels hold.

A large part of earth's population is in for a rough ride. To put it mildly.
