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.

Researchers at the workshop said countries like the U.S. can expect more tropical diseases to come โ€“ and should be preparing for them. Global warming is expanding the range of some tropical insects and diseases.

Gene drives are incredibly dangerous.

Just imagine if someone released a gene drive in humans, and somehow we fail to discover it for a few generations. That might be hard to imagine in a setting with lots of genetic testing, but what if it is released first in poor countries where genetic testing is not common, or it's released shortly before or after our civilization collapses?

Be careful what you wish for.
