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.

Interesting tool. I saw a climate projection for 2050 a few years ago (wish I could find it again) that suggested that my area in Maine would be similar to the climate of Baltimore / D.C. Metro and began looking for seed distributors in that region. I figure that assisted migration and mixing genetics from our region as it exists now and the region it will approximate will possibly help to provide some semblance of resilience for the forest we manage. This tool, at thirty years later than the other, puts us as resembling western Missouri which shares many climactic features as the region I had initially targeted (a relief, such as it is) but could signal a loss of our coastal effects. I'm unsure how exactly to parse that alongside my understanding of sea level rise and the fact that Maine's waters are some of the fastest warming in the U.S.
