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.

Exceptional” atmospheric rivers that brought record rainfall and widespread flooding to western and southern Europe in February should draw more attention to climate change (www.ft.com)

Portugal has been devastated by floods this year...

Better than drought. You can build for floodproofing. You can't build for drought.

The problem is always the unexpectedness of it no? You can build for drought too.

Reservoir lakes are building for drought. Food forests and regular forests are building for drought. Wells and aquifer taps are building for drought. Irrigation systems and drinking water distribution infrastructure are building for drought. Gardens and parks using arid climate plants is building for drought.

Floods can aggravate drought by destroying the above, including destroying natural plant life that is retaining water during droughts.

All good points. But food forests need water in the first place.

Food forests capture and retain water, and at scale affect the climate to increase humidity. They are actively being used to prevent the desertification of the Sahel region - see the Great Green Wall project.

They do need some water, but as an anti-drought measure they are indispensible.

Good point. But it's tinkering at the margins and we don't have long term data on viability and resiliency of any of it. Could revert to desert.

The people working to build the GGW are doing more than their fair share. Minimizing climate change is going to take everyone "tinkering at the margins" at the same time. As well as industrialized nations stopping shitting the bed.

Climate change could overpower the GGW if it gets bad enough, sure, but until then it's food security, carbon capture/retention, biodiversity preservation, etc. It is worth the effort.
