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.

In the European Union (EU), 47% of electricity now comes from renewable sources like wind and solar, a new record according to a report from the think tank Ember. This is a far higher percentage than in other countries, including the United States and China, where about two-thirds of energy comes from fossil fuels such as oil, coal, and gas.

For the first time in 2024, solar energy surpassed coal in generating electricity across all 27 EU member states, while natural gas production of electricity fell for the fifth year running.

Climate change experts are encouraged by Europe’s continued push toward cleaner energy, especially as the new U.S. administration pushes for increased fossil fuel use.

“Fossil fuels are losing their grip on EU energy,” said Chris Rosslowe, the lead author of Ember’s ‘European Electricity Review’. “Back in 2019, at the start of the European Green Deal, few believed the energy transition would be where it is today: wind and solar are replacing coal and driving gas into a structural decline.”

The share of electricity produced by renewables jumped to 47% last year compared to 34% in 2019, in large part due to strong growth in solar and wind energy. In 2024, 11% of the EU’s electricity came from solar power, 17% from wind, and 24% from nuclear. The share produced by traditional fossil fuels dropped from 39% in 2019 to 29% in 2024.

If only this progress had happened for happier, nobler reasons.
