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.

As per the article:

Flights with a rail alternative that takes less than two and a half hours will no longer be allowed, “except in cases of connection with hub airports that link with international routes”.

The only trip that I know of that takes less than 2.5 hs by train is Madrid-Barcelona and Madrid-Valencia . But Madrid is an international hub with connections to most of the international routes. So, my thinking is that this would not apply. It might only make sense for private flights, which are already very minor, AFAIK.

Again, smokescreen law, from smokescreen leftist party.
