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.

That the two hottest Junes have been the last two is not a coincidence or a statistical fluke. It simply reflects what is happening to the planet: it is overheating because of greenhouse gases emitted by humans, primarily from the use of fossil fuels (oil, gas and coal). Climate change has ushered Earth into an era of fleeting records and a stringing together of historic highs. For example, the last 11 years have been the warmest on average for the planet as a whole.

an estimated 9 million die from hunger every year, that's 750, 000 a week

an estimated 9 million die for air pollution as assholes won't stop driving cars and flying in planes etc, that's another 750k a week

i think it fair to point out that people really don't give a shit ?

Climate change is also cause for those hunger deaths...
