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.

I would have assumed that was always the chief reason right?

Yeah well, science isn't good at proving stuff that isn't true... The real mystery is how we get the truth to be as persuasive as an oil lobbyist.

A lot of those pathetic excuses for politicians sell humans out for as little as $500 so money is probably the only thing they hear

Faster than expected...

I feel like I've heard this before.

No forest, no rain.

Considering the Amazon rainforest is largely man-made, we'll just make it again

Read: https://en.wikipedia.org/wiki/Amazon_rainforest#History

The BBC’s Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.[20] Terra preta is found over large areas in the Amazon forest; and is now widely accepted as a product of indigenous soil management. The development of this fertile soil allowed agriculture and silviculture in the previously hostile environment; meaning that large portions of the Amazon rainforest are probably the result of centuries of human management, rather than naturally occurring as has previously been supposed.

The duck are you talking about?

The amazon rainforest was not originally a large rainforest. The ground was essentially terraformed, made fertile and trees planted by the ancient amazonians over thousands of years

Source: BBC unnatural histories, for over 11000 years the ground was terraformed with "terra preta" and forest was planted and converted
