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.

What they're saying: "Unfortunately, we cannot wish away the security threats associated with climate change," said Erin Sikorsky, director of the Center for Climate and Security.

"As a former intelligence officer, I fear that by eliminating climate threats from the [threat assessment], the DNI will create a chilling effect across the intelligence community," Sikorsky told Axios via email.

So what does Trump's US do/say about the very obviously increasing natural disasters that are making homes uninsurable, especially in Florida or California.

It's all well and good to say "we don't want to acknowledge this exists" (well, actually wait, it's clearly not well and good!?) but the fact is that climate change will wreck many American homes, and having an official policy that it doesn't exist makes it hard to do anything about it.

Honestly, I don't even know why I'm trying to reason around the actions of a deranged facist state government.

Too bad lying about it won't make it go away.

Good luck with that, idiots.

The level of obstinacy and stupidity in this administration never ceases to amaze me.

Each year the WEF publishes a Global Risk Report, surveying over 300 global experts and leaders from business, government, and academia on what they believe are the most pressing threats facing the world. For the past 3 years, climate change and its associated impacts have consistently ranked #1, #2, and #3 among all quantified threats.

To not only downrank this threat, but pretend that it presents no risk entirely implies that the US doesn't even have object permanence at this point.
