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.

Didn't the last five years smash the records of the previous five years which smashed the records of the previous five years and so on...

Every year is a record year, now.

Looks like it started around the 70s. That plenty of "five year buckets" in 5.5 decades.

I can say from a human perspective in my area the big difference was the 90's. Mainly that winters that were normal in the 80's were considered severe in the new millenia. Its kinda funny because we just had that. People were like wow this winter is brutal and its like. This use to be what you would expect. Thing is now people expect it to be mild.

there is a weather event called el Nino going on which will make it extremely bad this year.

[–] zwerg@feddit.org 1 points 2 days ago (1 children)

Next year, at least in Europe. Maybe it hits America this year?

Either way, better stock up on stuff to protect yourself from the Sun/Heat. I am talking UV portection hoodies, Sunskin, and portable cooling solutions for both your home and to go. And make shure your Grandparents and parents do the same, older people are much more vulnerebal to the heat.

Yeah and every year after that for the rest of our lives.

Look on the bright side, this’ll be one of the coolest summers of the rest of your life. 🙃

Are you guys practicing your mad Max make up and cool quotes. I'm already building a junker in the back yard, can't wait.

[–] MrWrinkles@leminal.space 7 points 2 days ago (1 children)

I should find me a station wagon and a hot mom.

[–] SkaveRat@discuss.tchncs.de 6 points 2 days ago

Sorry, all that's available is a hot wagon and station mom
