The predicted number, which includes deaths since June, likely represents an underestimate of total deaths. The heat could linger beyond February, and the climate swing could bring about other life-threatening conditions, including flooding, wildfire and infectious diseases

    Half of Earth’s population is alive thanks to nitrate fertilizer,

    Only if you count the animal torture industry in “the population”. More protein is spent keeping cows alive than humans.

      I do mean about 4 billion of them https://ourworldindata.org/how-many-people-does-synthetic-fertilizer-feed

      humans eat 2/3 of global crop calories. don’t spread misinformation.

        Calories are not protein. Humans burn lots of calories doing stuff animals in factory farming settings won’t, such as being living adults that don’t lactate kilos per day, or going for a walk, or doing physical labor.

          protein has calories.

          36% of global crop yields are fed to animals.

          None of what you’ve said here has refuted the person you’re responding to, I just want you to understand that.

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.
