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.

Fuel prices have pushed a lot of people and businesses to finally buy their first electric car or truck or crane or bulldozer or whatever, and they aren't going to set it on fire and replace it with diesel gear if fuel prices go back down again. At most, they'll sell it to someone else who will use it instead. Those electric equipment purchases have permanently removed fuel demand.

That's a bit dramatic.

The fuel prices have certainly made EVs more desirable, and that change in perception won't dissipate.

However, manufacturers didn't magically have more product arriving at market for consumers to buy in the few months this crisis lasted.

probably cut the costs on equipment and maitenance, granted they might need more specialized maitenenace care.
