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.

Does that mean we get a rainy winter in europe?

I don't think I've seen studies of any kind of teleconnection between Gulf of Mexico conditions and European weather, though higher temperatures tend to mean both more intense rain and more intense droughts.

Gulf stream is the teleconnection. It transports summer heat of Mexico to europe winter, major factor to mild climate in europe. With all the hubub about it weaking due to climate change, i thought this was common knowledge. Guess more in europe?

Look at something like this and it's pretty clear that the impact of this year's events aren't obvious like that. Not impossible, but I don't think I've seen what you're describing.

Thanks for the map, but it is, more or less.

The Gulf Stream influences the climate of the coastal areas of the East Coast of the United States from Florida to southeast Virginia (near 36°N latitude), and to a greater degree, the climate of Northwest Europe. A consensus exists that the climate of Northwest Europe is warmer than other areas of similar latitude at least partially because of the strong North Atlantic Current.

Yes, but that's very different from saying "I can discern an change in behavior of European weather based on what this storm did"

More because of why that storm came to be; lots of warm water
