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.

New Climate Report Warns of Imminent Climate Tipping Point As Emissions Soar (earth.org)

A growing body of scientific evidence now suggests that, due to rapidly increasing greenhouse gas emission levels in the atmosphere, the world is on track to overshoot the Paris Agreement’s 1.5C target within the next three years, pushing the planet beyond a critical threshold faster than previously feared.

The dire warning comes from the most up-to-date assessment of the state of global warming, led by a group of international researchers and published in Earth System Science Data earlier this month. The report was signed by over 60 scientists across 17 countries.

I thought we passed 1.5C last year?

At this point it is just shifting goalposts.

No one wants to admit that humanity is fucked because then all efforts (what little efforts those may be) to calm the incoming storm will come to a halt.

Plus the powers that be are intentionally trying to prevent mass panic by sanitizing the message as still being hopeful so that people continue to engage with their respective economies. Most people only go to work because they think they are working towards some type of future. Tell them there is none and they no longer will go into their jobs to generate revenue for the oligarchy to profit from. The oligarchy doesn't want that.

IIRC, it has to be passed for 3 years in succession.
