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.

Britain responds to Iran war energy shock by requiring solar panels and heat pumps in all new homes (www.cnbc.com)

The U.K. government on Tuesday introduced new rules requiring developers to install heat pumps and solar panels in all new homes across England, in policymakers’ latest response to the economic fallout of the Iran conflict.

U.K. ministers say the Iran war and the largest supply disruption in the history of the oil market reinforces the need to leverage clean power as an energy security tool.

The Future Homes Standard — a set of new-build regulations for England from 2028 — will establish requirements to ensure homes are built with on-site renewable electricity generation, the majority of which is expected to be provided by solar power.

The rules will also see homes built with low-carbon heating, such as heat pumps and heat networks.

The government added that plug-in solar panels, which homeowners can install on balconies, would be available within shops over the coming months.

They created huge pollution by switching off nuclear power. And now they are stuck between fossil fuels and renewables. Which still pollutes a lot and it'll hardly get much better, let alone zero emissions. They also bet on h2 only to scrap or postpone it. Which gives what?
