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.

Years of scientific research have found the climate crisis is causing heatwaves to become longer, more frequent and more intense.

I don't even want to imagine 50 C. In sauna, it's dry and you manage 30 minutes by sweating. But living in a sauna sounds bloody awful.

Also, almost anyone with a med / bio background will say - emergency rooms will be full at 50 C, and morgues will be crowded a few days after the event. :(

From the article:

At the SMS hospital in Rajasthan’s capital, Jaipur, so many bodies of casualties of the heat have arrived at the mortuary that its capacity has been exceeded.

That's 122.9°F for those who can't feel in Celsius. It also rained a little in the morning and the humidity was about 45%.

I did a little check and the hottest day this week in Death Valley is supposed to be 113° tomorrow with about 9% humidity.

Just for comparison.

HOWEVER, news sources from India are now reporting that number to be an anomaly compared to still-excessive-but-not-a-record numbers from neighboring sensor stations. It could be from hot winds but possible it's a malfunction. Investigation ongoing.

Haha that reeks of "those number don't help someone who can influence this" let's remeasure.

[–] Mouselemming@sh.itjust.works 1 points 5 months ago

Possible, although it was apparently more than a few degrees different from the others. And everyone seems to agree it's too damn hot, the only question is, "New High Score?"

Wasn't that how "ministry for the future" started?

[–] Goodtoknow@lemmy.ca 9 points 5 months ago

yup, and climate scientists have known for years India would be one of the early and hardest hit nations/regions due to climate change

I saw one yesterday about a record heatwave in Pakistan. What causes such extreme heat in that region?

Several things in combination:

  • It's sufficiently close to the equator
  • Topography limits air circulation
  • heat dome
  • Dumping the waste from fossil fuel burning into the atmosphere raised it above where temperatures used to get
