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.

I'm extremely worried about India. While, luckily, Climate is not a politicised issue, they are still spending their energy on religious bullshit instead of climate adaptations. They really need to be spending basically all the wealth they have on adaptations across regions or they are in for a massive shock.

Nice article, many examples. Except that it’s not just mountain communities that depend on glaciers - those are a key source of water for the main rivers during the dry season, especially at the western (Indus) end of the Himalayas.
Of course India could be better prepared, but the government needs to show this is a priority, rather than temples and Hindutva.
Maybe regional state governments could do better ?
The article is right to say that 1.5C is only a political goal not deduction from physical-science, a target which the Indian government did not, afaik, explicitly support, despite pressure from all the smaller neighbouring countries which clearly did. India always emphasised equity in the climate negotiations, but too much from a point of view of equitable access to global atmospheric space (i.e. right to burn coal too, proportional to population). So they got lumped together with China which has hugely higher emissions (also higher per-capita than europe), rather than with the most vulnerable countries (especially in Africa) which will receive most of the adaptation funding.
