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.

Controlled burns do produce less carbon though. They burn the lighter underbrush at lower temperatures while leaving lots of the carbon dense older growth (relatively) untouched.

And sometimes it's used to create a barrier so the fire encounters a span of spent fuel to contain its spread. It's still just addressing the symptom. The author seems to be under the belief that people are ignoring "black carbon," when in reality, things like controlled burns never stopped. Nobody is ignoring it, and its increased intensity and frequency is a symptom of the climate change we're causing.

It's like arguing that we need to cool the oceans. Duh. We'll do that by focusing on the core problem of our emissions, and we'll still have work to do as the climate recovers (should we make it that far).

Agreed, just wanted to point out that controlled burns are good and not as bad as uncontrolled ones :)
