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.

If we continue this trajectory, here are a lot of highly populated and productive urban economic centers that read:

"Future climate for this location is expected to be unlike anything currently found anywhere on Earth, so there are no climate matches for this location."

These are the most densely populated cities on earth. In the most peaceful 2080 scenario, all that you (or your descendants) would have to worry about in Scotland is that suddenly all these people would be on your doorstep, overburdening your supply chains, disrupting the job market and driving prices relentlessly upward because Scotland suddenly has very temperate weather and everybody wants to be there. Congrats, enjoy the new traffic and strained healthcare system.

In the most realistic scenario, there's endless war, death, and suffering globally as human migration on a scale we've never seen disrupts everything everywhere.

Thank you I'm aware of that, hence why I explicitly caveated my post as being dark humour.
