Climate - truthful information about climate, related activism and politics.

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 climate committee, stood up just before President Biden left office, was established to provide NOAA with advice on making its data and tools better available for those managing droughts, floods, wildfires, heatwaves and other impacts of climate change.

NOAA/NHC tools are already pretty decent. NOAA hopefully doesn't get a lot more cuts, and maybe these advisory committees aren't critical, even if it provided spokespeople that could speak outside of a narrow employee mandate/lane.

Woodchipper. It stands in the way of private weather services and their profits

Private weather services currently benefit from NOAA/NHC significantly. NHC is usually conservative with hurricane estimates at landfall, though storm surge is correctly put at maximum risk. There are very good private weather/hurricane modelling software in the world. Much of it not American. Youtube is a good expectation of "private weather services". Alarmism gets views, and there is often one model to get alarmist about.

NOAA plane reconnaissance of hurricanes is an important input into the mentioned models, and adds precision over satelitte data. The communication level of NOAA to public and local officials saves lives.

This year a very extreme hurricane got all the way up to Appalachia and did record monumental flooding. Somehow GOP made people mad at FEMA, just as they got mad that LA firehydrants can't put out forest fires. The point is that increasingly catastrophic disasters response is not going to be better by gutting FEMA or preparedness from NOAA.

Sorry, I'm not supportive of the gutting of NOAA, actually fucking depressed about it. But it is still happening

I feel a bit better knowing they were just created. Yeah would have been nice to have but clearly did ok before it existed.
