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.

India’s heat waves are attributed to a combination of short-term weather patterns and long-term warming trends fueled by human-caused climate change. Residents in India’s sprawling capital are often particularly affected, because dense buildings, roads, cars and air conditioners contribute to urban heat, experts say.

It’s starting. We’re not even into summer yet. And next year will be worse, and the year after that will be worse than that, with no particular safety measure or merciful limit.

And even when it reaches a protein-denaturing threshold and people start dying for real, by the thousands or more, we'll still be burning gasoline, setting new records for "production."

If Im not mistaken, Delhi's hottest month isn't in peak summer but in May and June, so now. As the climate is largly influenced by the monsoon season.

Next year also doesn't necessarily need to be worse, now going from an el niño into a la niña makes that somewhat unlikely, although regional differences will probably make some places worse, compared to this year.

Please correct me if I'm wrong, but people may be already dying by the thousands. Isn't it rather difficult for a doctor to point down the reason of death to heat?

If not next year, it will get worse rather quick, that's for sure. Much, much worse.
