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.

Penguin chicks miraculously survive tearaway iceberg (www.bbc.com)

In May a huge iceberg broke off from an Antarctic ice shelf, drifted, and came to a stop - right in front of “maybe the world’s unluckiest” penguins.

Like a door shutting, the iceberg's huge walls sealed off the Halley Bay colony from the sea.

It seemed to spell the end for hundreds of newly-hatched fluffy chicks whose mothers, out hunting for food, may no longer have been able to reach them.

Then, a few weeks ago, the iceberg shifted and got on the move again.

Some bittersweet news, with an important reminder of how much more precarious life is for creatures living on the Earth's poles due to the changing climate.
