NASA map of permafrost areas vs current temperatures.
The permafrost is already melting, and releasing trillions of tonnes of methane into the atmosphere. Look at how warm it is in Alaska and Siberia. It's shorts weather.
The current auroral ovals above the north and south poles, or more accurately, a visualision showing the probabilty of seeing aurora at different locations on the planet:
A peek into the jet stream shows a massive meander bringing cold air from the North. Courtesy of #GlobalWarming: less temperature differential between the poles and the equator weaken the jet stream which then meanders more, swinging the weather from cold to hot and to cold again over the space of a couple of weeks as meanders shift about.

@PhETsims@edutooters Science and Maths teachers, if you haven't tried the PhET Sims, you are missing an invaluable resource. Particularly if you don't have all the resources you might wish for (and even if you do!)
Any #slackware#current#nwgshell users want to try the latest hyprland, I’m not adding it to the repo (yet) but I put the needed pkgs here: https://slackware.lngn.net/pub/staging/ install/upgrade them in your existing (x86_64) install. It works, but I haven’t tested all the things yet.
One thing I love about the #fediverse is that I visit so many more websites than I used to.
I confidently click on links from you lot all the time and end up in magical places! ...a far cry from the “five giant websites, each filled with screenshots of the other four”
@Nifflas I don't think I had strong opinions on map projections before reading the webcomic... now I most certainly do!
I discovered xkcd about a month after this one came out, and tried to find a framed Waterman Butterfly... sold out EVERYWHERE - I really should investigate again.
@renegaderich I totally respect neat map projections that gives us a better representation of scales! But I'm a simple person, x/y for longitude and latitude is mathematically simple, and placing the seam where's the most ocean is just makes sense.
I like the simple mathematics of it, and I'm not tricked by the scale distortions, I've done enough UV mapping to take those into account.
Then again, I'm not claiming in any way that my favorite is the "best", only that it's my favorite.
A UK government that would propose installing small rooftop wind-powered turbines everywhere would very substantially lift geopolitical liabilities - and tilt the import/export balance significantly.
In other words the wind blows, often, and strong, like today. Harvesting a tiny fraction of the wind’s energy, in combination with solar panels and home insulation, would transform this country.
If the chimneys of coal-burning fireplaces in every room were a fixture of the glorified past, let wind turbines be the distinctive trait of present-day roofs.
There's quite a variety of forms of rooftop wind turbines, some large, some small. With lots of space for engineering developments to bring about new ones. Imagine every house with a ~1 kWh wind turbine and a small battery. What a change that would bring to the electric grid, from production to load balancing and more.
(Also, note the article you pointed to is 8 years old. Ancient history, given the fast pace of renewable energy developments.)
Same storm, second round two days later. How strong does the wind blow? I can smell the sea from Cambridge – that distinctive humid but warmish, salty but not quite aroma of my childhood.
Nigeria, India and China are experiencing pretty bad air pollution, as measured by density of particulates. No wonder China and India are rushing to replace fossil fuels for renewable energy sources. Let's hope Nigeria will follow suit.
