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.

Scientists said climate change helped shape the weather conditions that were causing misery and putting lives at risk from Mexico to Canada.

The smoke has reached Portugal as well now. Was a strange gloomy day here today.

Yeah, I've been watching fire.airnow.gov:

Screenshot from fire.airnow.gov. Air quality and smoke map showing smoke from wildfires on June 28, 2023 in North America and Western Europe. North America has air quality monitoring data showing air quality index, and smoke is overlaid in shades of gray. Smoke streches out from Canada into US, across atlantic ocean, and into Spain, France, Portugal, UK, and Ireland. The densest smoke in Europe is over Portugal and parts of spain

Edit: it looks like the US government didn't buy particulate sensor data from PurpleAir for outside of North America. You can see that for Europe here

It's sad and terrifying state of things right now from climate to ecosystems to empathy and connection amongst humans and towards our fellow animal creatures... hopefully we can right the ship or at minimum life continue without us...

I don't know about yall, but I'm super ashamed of being human...then am still able to find beauty in it, then shame again. oh lord, we are definitely not making it past the bottle neck, imho. Maybe with a lot less people, but that's just fine, can't help but be tbh.

It's not the number of people that's warming the world. It's the greenhouse gas emissions. Those largely come from the richest 10% of the world population.

Getting greenhouse gas emissions to zero will stabilize the climate. Failing that, even with a smaller population, and we won't.

The IPCC has a handy chart showing what needs to be done to cut emissions over the next few years.

Obviously the top ten percent is bustling and needy.

More people is more percent chance your gonna get greedy people, with more waste to feed off. Me, personally, I really don't need much tbh. Go figure (:

Thanks for the link, appreciate it.

Not really. There is a distinct pattern of high per-capita emissions in countries with low population growth and high population growth in countries with low per-capita emissions.
