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 current Senate draft of the US budget bill not only ends subsidies for wind and solar, but imposes a new tax of 30% or 50% of value on them, including on home rooftop solar, with any meaningful foreign-made components. You can't do any of this anymore without foreign-made components because the GOP is also gutting support for US manufacturing. Doing this is going to make US decarbonization effectively impossible.

If you're an American, call your representative and senators and tell them to vote down the bill so long as this is in it.

When the Trump administration began taking down federal resources on climate change, I started pre-emptively archiving reports and data sets in the event that they're no longer accessible. That proved to be a smart move, as the NCA5 website just went dark this week. That's a huge blow to the layperson, as that was one of the most comprehensive resources on climate change for our nation. Thankfully I had the data backed up on multiple hard drives and cloud servers, so we can continue to provide this information to those who need it.

So far I've archived the following resources (which are no longer available from their official websites):

The following resources are still live, but I've archived them pre-emptively for safety:

What other US government resources might be on the chopping block? I'm primarily looking for reports and data related to climate change, resilience, and adaptation, and ideally in a downloadable format (PDF, Excel, CSV, etc.).

The startup Gigablue announced with fanfare this year that it reached a historic milestone: selling 200,000 carbon credits to fund what it describes as a groundbreaking technology in the fight against climate change.

the company says it has designed particles that when released in the ocean will trap carbon at the bottom of the sea.

Gigablue expects the carbon to be trapped there for hundreds to thousands of years.

While Gigablue has made several commercial deals, it has not yet revealed what its particles are made of. (...) "It's proprietary,"

The success of the company's method, they said, will depend on how much algae grows on the particles, and the amount that sinks to the deep ocean. So far, Gigablue has not released any studies demonstrating those rates.

"What we've got is a situation of a company, a startup, upfront selling large quantities of credits for a technology that is unproven,"

In The imperative of defossilizing our economies report, Morgera argues that the United States, Canada, Australia, the United Kingdom and other rich fossil fuel countries are legally bound by international law to phase out gas, oil and coal by the end of the decade, in addition to compensating communities for the harms caused.
