Climate - truthful information about climate, related activism and politics.

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.

Here's the source of the data, I find it way more interesting than the app.

Thanks for sharing!

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.

I know this is awful and I shouldnt joke, but there is something darkly funny about seeing an article about how devestated the world will be, and then seeing it says Scotland will be like Bilbao for when I retire.

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.

I mean I kind of agree, most of the ones I tried were rather underwhelming. We've been joking for a while that Amsterdam would be the new Barcelona, but this tool gives you Bordeaux as a match which is a lovely place to be right now... Tried Edinburgh and the match was in Spain, so a much bigger differential but still I don't see how that would give any Scots such a bad feeling indeed....

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.

This will be fun at thanksgiving!
