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.

Study shows EV owners have bigger carbon footprint than average because they are wealthier (phys.org)

Maybe EVs are not a comprehensive climate solution??

I think the study analyzed the footprint of the person, not the vehicle:

In this new study, the research team investigated whether consumers who purchase and drive such vehicles have a smaller carbon footprint than other consumers

The merits of electric vehicles are irrelevant to their study - and their study is irrelevant to the merits of electric vehicles.

So maybe they're not lying (or maybe they are, if they made a direct claim about the power mix of the Finnish grid), but they're definitely far from barking under the correct tree. They're barking in a different forest, not of transport economy, but of wealth and consumption. :)

Quoting myself from another answer:

This paper takes it's data from a survey in Finland, so I believe it should use the Finnish power mix in it's conclusions or at least compare to it.

And while the study seems to make sense, the article is just awful clickbait.
