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:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.
It's interesting how all the pearl-clutching rhetoric behind climate-driven immigration I hear coming from the US (right) seems to be under the assumption people will be clamoring to move there as shit continues to hit the proverbial fan. However, from this layperson's perspective it seems emigration will be the far bigger reckoning for America.
Any idea on what the measurements are on the Y axis?
Edit: if you follow the link if shows the measurements are in kJ/cm^2^. Which is something someone smarter than me will have to explain.
How many degrees are off from the avg tho? Just something to compare it to.
Look at the averages on that chart. Eyeballing it, the average should be around 70 kJ/cm2, currently it's about 85.
So it's about 20 percent more energy.
It doesn't translate directly to temperatures as the values represent how much energy is in a column of water that is 1cm2 at the top, and that column extends down until the water temperature drops below 26 degrees Celsius.
So it could be that the top of the column of warm water is mostly the same temperature as before but extends deeper, as opposed to the top of the column being a lot hotter than usual.
When the column is shorter, a hurricane will mix it with cooler water lower down via wave action, reducing the amount of energy available after it passes by. This year the column of water is deeper than usual, which allows two hurricanes to develop over the same patch of ocean in quick succession.
Thanks for the explanation 👌
I was assured by (checks notes) the Governor of Florida that charts like these are fake news because global warming is fake news.
Silly, now you've broken the law in Florida because you've talked about climate change. That and signing petitions will get you a visit from the police! Totally normal state governmental functions.
Does that mean we get a rainy winter in europe?
I don't think I've seen studies of any kind of teleconnection between Gulf of Mexico conditions and European weather, though higher temperatures tend to mean both more intense rain and more intense droughts.
Gulf stream is the teleconnection. It transports summer heat of Mexico to europe winter, major factor to mild climate in europe. With all the hubub about it weaking due to climate change, i thought this was common knowledge. Guess more in europe?
Look at something like this and it's pretty clear that the impact of this year's events aren't obvious like that. Not impossible, but I don't think I've seen what you're describing.
Thanks for the map, but it is, more or less.
The Gulf Stream influences the climate of the coastal areas of the East Coast of the United States from Florida to southeast Virginia (near 36°N latitude), and to a greater degree, the climate of Northwest Europe. A consensus exists that the climate of Northwest Europe is warmer than other areas of similar latitude at least partially because of the strong North Atlantic Current.
Yes, but that's very different from saying "I can discern an change in behavior of European weather based on what this storm did"
More because of why that storm came to be; lots of warm water
