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.

Looks pretty bad but a little less brutal than the swiss one

Somehow, I don't think it's a competition.

They're all in the 2+/-.2 C range, and increasing in frequency.

What's different about the flyover states is they are flat, are running out of water, and all the increased tornadic/hail activity is just going to make them no-mans-land over the next half century, outside of the temperature issues. (And not trying to compete either, it's just weird.)

The amount of larger hail popping out of these storms is crazy too. Homes will need stronger roofs and windows, there will be more risk to aircraft as well with how rapid they seem to be popping off these days. (Secondary issues will be developing as well since the US is slashing weather prediction budget, which is reducing available data.)

Links on what damage to expect, a plane a few years ago that ended up damaged from a hail storm over New Mexico, double-sucks too, the airplane's weather radar is in the nosecone, so they lose their ability to see what they're flying through in that case:

What a weird statement lol
