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.

As a minimum, a local emergency deparment should have an automatic interface to the nearest weather radar. If a radar scan suggests "ocean falling down", people should be alerted with text messages in the same way they'd be alerted of a wildfire, chemical leak or incoming missile strike.

Absolutely, but I'm not sure if a bunch of text messages sent out at 2 am would have prevented that many deaths. This is unbelievably tragic, but feels like the new reality with climate change :/

100% prevention is probably unattainable, but in case of the childrens' camp an early word of competent instruction "get away from rivers and find shelter on high ground" would have probably helped a lot. Even if it would have woken up only 10% of the people, they could have woken up the rest.
