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.

fast fact: For westerners who still think of India as a faraway little spot, slightly under a fifth of the world's population lives there. More than 4x as many people as the USA. So this is kind of a major deal, humanity-wise.

Yes, it is a major deal humanity-wise, but India has been sovereign since 1947 and in the last 12 years made decisions to have the hottest and most polluted cities on the planet. Hellish urban heat island (UHI) construction predominates. Coal power and ICE vehicles ownership were rapidly expanded.

Global climate change, for which the West bears primary fault, is responsible for 1.5c of warming. UHI effects, through decisions India made, are responsible for 6-8c in the NCR alone and 3-5c in most other major cities.

I beg Indians to step up and start making the smart decisions to mitigate the wave of heat deaths drawing closer that will rival the British-created Bengal famine.

Nah, having about 1,5 billion people living there is one of the first things people on the West associate with India (and also China)

You'd be surprised. Some of us still want to give them maps and such as.
