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.

Air pollution tends to get worse before it gets better, but how can we accelerate this transition?

One discipline that has been targeted more specifically is climate science. President Trump has long downplayed the threats from human-caused global warming. At the National Oceanic and Atmospheric Administration, staff members have been ordered to comb their research awards for terms including “climate science,” “climate crisis,” “clean energy” and “pollution.”

Aurora Roth is finishing her doctoral studies at the Scripps Institution of Oceanography at the University of California, San Diego, and preparing to apply for jobs. Instead, she said, “I am wondering what institutions will even exist in a year.”

She and other scientists could figure out how to reword their funding applications to avoid mentioning climate change, Ms. Roth said. But “feeling attacked just on the basis of doing science in the world? That’s a hard thing to sit with,” she said.

No one alive will experience a better climate than we have today. But young people will experience a much more dangerous and chaotic world in the future.

The Centre for Research on Energy and Clean Air (CREA) and Global Energy Monitor (GEM) have released their H2 2024 biannual review of China’s coal projects, which finds that coal is still holding strong despite skyrocketing clean energy additions in 2024.

Even as China’s clean energy surged in 2024 and became a key economic driver, solar and wind utilisation dropped sharply in Q4 2024, which was not expected or explained by weather conditions, and coal remains strong, which ultimately goes against President Xi’s 2021 pledge to phase down coal over the following five years.

China approved 66.7 gigawatts (GW) of new coal-fired power capacity in 2024, with approvals picking up in the second half after a slower start to the year. At the same time, 94.5 GW of new coal power projects started construction and 3.3 GW of suspended projects resumed construction in 2024, the highest level since 2015, signalling a substantial number of new plants will come online in the next 2-3 years, further solidifying coal’s role in the power system.

...

Key findings:

  • Coal power permits and new project activity remain high despite some signs of slowing. In 2024, 66.7 GW of new coal power capacity was permitted – lower than previous years but still well above the levels seen in the first half of the year. Meanwhile, new and revived coal power proposals totalled 68.9 GW, down from 117 GW in 2023 and 146 GW in 2022, suggesting a potential cooling in project initiation.
  • Coal power construction starts reached their highest level since 2015. 94.5 GW of new coal capacity began construction, the most since 2015, highlighting continued momentum in project development despite President Xi Jinping’s pledge in 2021 to ‘strictly control coal power projects’. However, actual commissioning has slowed, with 30.5 GW coming online so far, down from 49.8 GW last year but in line with 2021 and 2022 levels.
  • China’s coal power expansion contrasts with global trends. While China continues to add new capacity, the global coal fleet outside China shrank by 9.2 GW in 2024, reinforcing China’s dominant role in shaping the future of coal power. China now accounts for 93% of global construction starts for coal power in 2024.
  • Long-term coal power contracts are reinforcing coal’s dominance at the expense of renewables. Electricity buyers locked into long-term coal power contracts face penalties if they fail to purchase contracted volumes, discouraging them from prioritising clean energy. With new coal capacity coming online, guaranteed operating hours under pre-signed agreements further limit grid space for renewables, delaying the transition to a cleaner energy mix.
  • Coal mining companies are playing a dominant role in financing new coal power projects. In 2024, more than 75% of newly approved coal power capacity was backed by coal mining companies or energy groups with coal mining operations, artificially driving up coal demand even when market fundamentals do not justify it. This not only reinforces reliance on coal but also risks undermining central government policy targets for curbing coal consumption and accelerating the energy transition.
  • Despite policy intentions for coal power to support renewable integration, 2024 approvals show a shift away from this role, with many projects justified by local governments based on economic development and local energy security instead. While some policies promote coal power flexibility retrofits, long-term contracts and the inherent limitations of coal plants regarding low-load operation and intra-day cycling discourage coal plants from performing a true regulating function.

The job cuts, which amount to roughly 10 percent of the agency’s work force, could hobble the Forest Service, which was already struggling to remove vegetation across its vast land holdings at a pace that matches the growing threat from fires, according to current and former federal employees, as well as private companies and nonprofit organizations that work on thinning forested lands.

Let me be clear, I certainly trust the climate scientists of groups 1 and 2 of the IPCC, but I am highly critical of the third working group that assesses options for the mitigation of the climate crisis. They are obsessed with technology. There are also good elements in their work, but in their latest report they constantly refer to new technologies that do not yet exist or are overvalued, such as hydrogen, CCS and bioenergy (BECCS).

The specific examples in this are all about climate, though the problem is much more widespread right now
