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.

Wolfgang Cramer’s first involvement with the Intergovernmental Panel on Climate Change was in the 90s. He worked on the second assessment report, delivered in 1995, which affirmed the science of anthropogenic climate breakdown. At that point, no one could say they did not know what was happening.

Almost three decades on, Cramer was part of the international scientific team that prepared the sixth IPCC report. Its conclusion, delivered in March, issued human civilisation a bleak “final warning” – the biosphere stands on the brink of irrevocable damage.

Now, as diplomats meet in Dubai for the 28th round of the Cop climate talks, in a year predicted to be the hottest on record, and as carbon emissions continue to rise, Cramer is one of 33 IPCC authors among 1,447 scientists and academics in signing an open letter calling on the public to take collective action to avert climate breakdown.

“We are terrified,” they warn. “We need you.”

@activistPnk here in France I think First Responders always have been able to change the lights, or ignore them with sirens blazing.
