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.

A new climate change map shows predictions for just how devastated the future climate will be in various places around the world. The map, which is called The Future Urban Climates, allows interested users to explore how their home area’s climate might change going forward.

The data used to create the map comes from the Intergovernmental Panel on Climate Change (IPCC), and it was created by University of Maryland spatial ecologist Matthew Fitzpatrick to showcase the future of climate change up to 2080.

Of course, all of the changes showcased on the climate change map are just predictions based on current trends of extreme storms, fires, floods, droughts, heat waves, and cold snaps—all of which continue to hit us harder each year.

Florida will be like Mexico in 2080? Somehow I think Florida will be more like Atlantis, but I guess we'll see.

Sea level rise takes a lot of time. The projections I saw were somewhere around 1 m by 2100 and 10 m by 2300, depending on the amount of warming of course. I think hurricanes will be a bigger issue for them in this century.

Those sea level rise projections are global. There will be local differences. I don't know what that means for Florida though.

Similar to how on land we'll probably see higher temps than the global average, just because the sea is able to absorb so much more energy.

Also recent studies may indicate that melt rates in the Antarctic are higher than previously thought.
