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 growing field of ​“firetech” is reinventing the age-old practice of prescribed burns and devising other novel methods of preventing and suppressing fires.

What they're doing is showing how to make it cost-effective to go back to something like the pre-colonization fire regime of frequent low-intensity fires. This makes it possible for western North America forests to return to having fewer but older trees which sequester more carbon than growing lots of small trees fast and then having them all burn in an intense fire

sounds cool, but the solution to global warming is socialism with mild capitalist traits. tech bro solutions always include extra steps and are profit driven.

If you look at who is involved, its a bunch of forestry and fire ecology types with a few tech people supporting them

i give u credit: i didn't read the article, just assumptions
