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.

In europe its a horrible heat wave right now. 28C in sweden where i live which is very much not normal.

It was 34°C where I was on Saturday in western Canada. Thankfully cooling off quite a bit in the next few weeks though down to highs of 18-20.

What is that in human units? I know 30C is balmy and 20C is pretty crisp...

Its 82f which isnt a lot but in sweden it is. The southernmost point of sweden is more northern than the southernmost point of alaska.

82⁰, cry me a river. That's mildly warm.

Ahh it's a bit different if all your buildings were never made with such temperatures in mind. Not to mention if you've never seen such temperatures in your usual day to day.

We get around -2c to 40c+ where I live depending on the season, summer here floors people from colder climates.

Okay but if you went out in -10(14f) in a shirt you would probably freeze and sometimes i see people here out in -20(-4f) without a coat so it depends on where you live. In hungary(where im from) 28(82f) is extremely lucky in summer but instead we get 40(104f) which isnt my favourite weather.

Human beings regularly die from hypothermia, in the temp ranges you referenced.

Dying in 82⁰ F from heat-related injury is unlikely.
