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.

Hurricane Helene is now forecast to reach catastrophic Category 4 strength by the time it makes landfall in Florida on Thursday, the National Hurricane Center says, with storm surge potentially climbing to 20 feet along some parts of the coast.

Helene could be the strongest hurricane to hit the United States in over a year – and time is running out for those in its path to prepare.

“A catastrophic and deadly storm surge is likely along portions of the Florida Big Bend coast, where inundation could reach as high as 20 feet above ground level, along with destructive waves,” the center warned. “Preparations to protect life and property should be completed by early Thursday before tropical storm conditions arrive.”

Helene rapidly intensified into a hurricane Wednesday and will continue strengthening as it crosses over the record-warm water of the Gulf of Mexico. Rapidly intensifying storms like Helene are becoming more frequent in a world warming due to fossil fuel pollution...

Returning to British suburbia from the Brazilian Amazon is always disconcerting, but it has been doubly weird in the past few days because the London commuter belt has been inundated with volumes of rain that normally belong in the tropics.

Mini-tornadoes, flash floods and the dumping of a month’s worth of rain in a single day have flooded transport hubs, high street pubs, and the shrubs of semidetached homes.

If that sounds unnatural, it is. This weather does not belong in the safe, predictable, home counties of England. At least, not in a normal state of affairs.

But ever-greater combustion of fossil fuels has turned the world’s climate on its head. In the past week, the northern latitudes are behaving like the equatorial margins...

Nearly 4.1 billion people, roughly half the planet’s population, experienced unusually hot temperatures between June and August, in what was Earth’s hottest season on record.

Climate change made these high temperatures three times more likely, according to the latest report by Climate Central, a US-based non-profit of scientists and science communicators that conducts research on climate change...
