One recent study cast the well-known declines in air pollution during the COVID-19 pandemic in a darker light.
These cuts remain one of the only examples of successful cuts to climate-warming pollution, but the new study found that those pandemic-era cuts in air pollution led to a rise in global temperatures.
The findings, published on Wednesday in the journal NPJ Climate and Atmospheric Science, unveil a stark paradox at the heart of human-caused climate change.
It suggests that while cutting fossil fuel pollution is necessary for avoiding severe destruction over the long term — such cuts will make things noticeably worse in the short term.
The pandemic-era economic slowdown led to “a large-scale geophysical experiment,” study leader Örjan Gustafsson of Stockholm University said in a statement.
That’s because the shuttered factories and power plants led to a corresponding crash in emissions.
Even so, not all emissions fell in the same way.
From a research station in the Maldives, an island archipelago off the coast of India, Gustafsson’s team detected that when pollution from smokestacks fell, so did concentrations of aerosols — tiny floating particles that hang in the atmosphere.

Why using rare metals to clean up the planet is no cheap fix | New Scientist

He is neither a climate sceptic nor a fan of inaction. But as the world moves to adopt a target of net-zero carbon emissions by 2050, Pitron worries about the costs. The figures in his book The Rare Metals War are stark. Changing the energy model means doubling the production of rare metals about every 15 years, mostly to satisfy demand for non-ferrous magnets and lithium-ion batteries. “At this rate,” writes Pitron, “over the next 30 years we… will need to mine more mineral ores than humans have extracted over the last 70,000 years.”

A pledge to fight climate change is sending money to strange places (reuters.com)

ITALY helped a retailer open chocolate and gelato stores across Asia.
The United States offered a loan for a coastal hotel expansion in Haiti.
Belgium backed the film “La Tierra Roja,” a love story set in the Argentine rainforest.
And Japan is financing a new coal plant in Bangladesh and an airport expansion in Egypt.
Funding for the five projects totaled $2.6 billion, and all four countries counted their backing as so-called “climate finance” – grants, loans, bonds, equity investments and other contributions meant to help developing nations reduce emissions and adapt to a warming world. Developed nations have pledged to funnel a combined total of $100 billion a year toward this goal, which they affirmed during climate talks in Paris in 2015. The funding helped crown Japan and the United States as two of the top five contributors.

I didn't either, it could be that fungi absorb CO2, fine, but when it dies or gets eaten, it doesn't lock away the CO2.

Georgia nuclear rebirth arrives 7 years late, $17B over cost | AP News
Yeah, my dad worked on that, but left after all the delays and Westinghouse came in.  He's one of the "experienced workers in short supply" and had to redo a lot of the other's work and just got tired of waiting around to get his tasks done.
.
The 20-25 year pause on US nuclear power is a problem.  All of the people who can do the job are either very old or have zero actual experience.

Don't see anything even postulating a solution there...

It is, it was, and it will be, outrageous, but at least they did get finished, finally.  It's probably the most expensive power plant EVER.
