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.

Even in Germany, there are now regularly more deaths from heat waves than traffic deaths (and air pollution is another big killer whose effects are multiplied by heat waves)

Summary: Sales of pure Electric cars have overtaken sales of purely petrol cars in Germany in March, following incentives and oil crisis

Pure electric car registrations in Germany rose 66% year-on-year in March to nearly 71,000 units, pushing their market share to 24% and edging ahead of petrol cars, which fell 5% to 67,000 (a 23% share). The milestone reflects two concurrent drivers: a new government subsidy programme targeting lower-income buyers launched at the start of 2026, and a sharp oil price spike driven by the Iran war that has significantly boosted consumer interest in EVs — though that demand will take months to fully show up in registration data given delivery wait times.

Hybrids dominated overall with a 40% share (~118,000 units, up 16%), while diesel continued its decline to ~38,000 units (13% share). Private car purchases grew particularly strongly, trimming the company car share to 65%. Tesla staged a notable recovery — sales more than quadrupled to over 9,000 after price cuts, following the reputational hit from Elon Musk's political activities. EV sales remain well below the government's target of 15 million EVs on the road by 2030.

Environmental Protection Agency Administrator Lee Zeldin delivered the keynote speech at a Wednesday meeting of the Heartland Institute, a group that challenges the overwhelming scientific consensus on climate change’s harmful impacts and the need to curb greenhouse gas emissions that cause it.

Last month, climate scientist and author Kate Marvel resigned from her position at NASA’s Goddard Institute for Space Studies, where she had spent more than a decade studying a warming world. In her resignation letter, she cited the Trump administration’s attacks on the field.

“I anticipated that our work would be questioned,” she wrote, “but only because its implications were politically inconvenient. I never expected that science itself would come under attack.”

Marvel joins more than 10,000 professionals with doctoral degrees in the sciences who have left the federal workforce since President Trump took office in January 2025: a period that has seen the administration evict the Goddard Institute from its historic home on the Columbia University campus, dissolve the U.S. Global Change Research Program, dismiss the nearly 400 authors of the next National Climate Assessment, and repeal the legal foundation for federal regulation of greenhouse gases.
