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.

don't worry, USA cut all of the ability for the EPA to do anything, so this will definitely get better.

I understand the naysayers' point but a functioning EPA would work WITH Canada. We could, you know, be a good neighbor. Together both nations could help predict fires, track them, respond together, etc. The current environment of aggression is not the only possible course of action. Unfortunately, there is no hope in that changing this moment.

I cannot stress enough that Canada is a sovereign country and not under the jurisdiction of the EPA.

Oh yeah i know lol, im just bitching that the US has no way to do anything about this.

You watch they'll use tariffs somehow

Sure it does. It can send help.

I thought it was like a hat or something.

The EPA can't do anything about Canadian forest fires. Canadian Right wingers have cut firefighting budgets and dropped emissions laws to align with the USA, so this problem, which literally never happened before 5 years ago, will be the new summer experience for North America.

The market will regulate itself and improve air quality
