Richard Somerville on the long history of climate change science “Everything depends on what people and their government do,” Somerville writes, not once, not twice, but (if I count correctly) seven times.

A new book worth checking out. “You might think that the science of climate change is young, and that scientists developed it only a few years ago,” Somerville writes. “That is not true.”

Have Economists Underestimated the Cost of Climate Change? A new study suggests global warming could slash global GDP by up to 30% per degree of warming and reshape climate policy debates.

New research: "a permanent 1C increase in global temperature could reduce world GDP per capita by more than 20% in the long run, with some estimates approaching 30%." Even if it's half that bad, it's really bad...

Climate change is speeding up — the pace nearly doubled in ten years Earth is now warming at a rate of around 0.35 ºC per decade, fresh analysis finds.

With an El Niño on the way, we're likely to see yet another jump in global temperatures in 2027 as the ocean gives up higher amounts of heat to the atmosphere. www.nature.com/articles/d41...

Scientists are trying to solve the mystery of whether global warming is speeding up. A new study says it has the answer | CNN Is the world getting hotter, faster? It’s a big question which has been puzzling and dividing scientists for years. A new paper says it has the answer, and it’s not good news.

He's talking about the U.S.: “I just could not have imagined that policymakers would get such clear evidence that we are heading into a very serious disaster for humanity and not act.”

Sea Levels Are Already Higher Than Many Scientists Think, New Study Shows

“from a global perspective, the findings indicate that hundreds of millions more people — particularly in… Southeast Asian & Pacific nations — are living closer to sea level than widely assumed by Western experts & policymakers”

Western US snowpack is still looking BAD. Hope for snow, but plan for low river flows and severe wildfire risk.

This is why our electricity bills are so high right now — Ars Technica New data shows electricity rates rose 5 percent nationwide in 2025.

There are a growing number of reasons why electricity prices went up so much in 2025, and will go up more in the future. Bad energy policy is one reason, surging natural gas prices, infrastructure build out for increasing demand, and now another war.

The College Backlash Is a Mirage Americans are more pessimistic than ever about the value of a degree—but enrollment keeps going up.

College degrees are worth it more than ever, and people know a degree is going to help build many types of career: "Despite the reported skepticism of higher education, enrollment in four-year colleges and universities is growing."

Fossil fuel giant wins $370 million tax break for burning gas as an ‘alternative fuel’ The IRS allowed one of the world’s largest exporters of natural gas to claim its heavily polluting tankers are low-emissions “motorboats,” the company said.

No corruption here…

VOICES: Why solar still makes sense With 10-year payback and 30-year lifespan, solar panels protect Metro Detroit residents from rising utility costs and blackouts.

Michigan going electric... Fun facts I just learned: EV & plug-in hybrid EV registrations in MI jumped 126% from 2023 to 2025, & the number of public DC fast chargers in the state jumped 84% from 2024 to 2025. Pretty easy (& more affordable) to ditch the old internal combustion vehicle in MI

Supreme Court’s Michigan pipeline case is about Native rights and fossil fuels, not just technical legal procedure The issue in front of the US Supreme Court is seemingly mundane, about federal or state jurisdiction. But it is actually much bigger, encompassing some key questions of the 21st century.

Excellent overview of the Line 5 SCOTUS case and the threats the pipeline poses to the Great Lakes, to Tribal rights, to state rights, and to climate change. It's infrastructure of a by-gone era that threatens too much.

From Energy Use to Air Quality, the Many Ways Data Centers Affect US Communities Energy prices and water use aren't the only ways data centers affect U.S. communities. We break down the impacts — and how some states are dealing with them.

Excellent new data center overview doc. Note, however, that this is not a great idea: "Two-thirds of U.S. data centers built or in development since 2022 are in water-stressed areas."

Climate change is already costing Colorado. A new report estimates how much costs will rise through 2050. Shorter ski seasons, hotter summers, longer wildfire seasons, increasingly burdened infrastructure and other climate-related impacts could cost Colorado up to $37 billion by 2050.  This is according t...

Colorado has an idea what climate change will be costing the state by mid-century: "Climate trends like deepening drought and extreme heat could wind up costing Colorado up to $37 billon"

Is Climate Change Making Inflation Worse?

Climate change also driving up inflation? “There’s mounting evidence that more frequent extreme weather events do make some things more expensive. But how that plays out depends on where you live”

Economists Still Agree on Climate Change | The Regulatory Review Despite the retraction of a recent study, economists still agree that climate change is expensive and dangerous.

1 of 38 studies retracted, consensus remains strong: "An overwhelming majority of economists agree that the damages of climate change will be large, and the costs of climate inaction significantly exceed the costs of action."

Snowball Earth might have had a dynamic climate and open seas Sediments from Scotland hint that ocean-atmosphere interactions continued more than 600 million years ago despite widespread ice.

As a fan of varves (annual lake sediment layers), this story is cool. We knew the ancient "snowball" Earth climate was really more of a slush ball, but quite interesting given that the distribution of continents 700 million yrs ago was way different.

‘Ghost forests’ are even more widespread than we thought These haunting landscapes, with their unmistakable gray, barren tree trunks rising like sentinels, offer one of the most startling and recognizable signals of a changing climate.

Guess what’s killing trees. “The coastal forests most at risk from sea-level rise and saltwater intrusion sequester massive amounts of carbon. They mitigate the impact of storms, play a key role in water quality for nearby communities and provide habitat...”

Fate of Colorado River hangs in balance as political battle brews The fight over the dwindling Colorado River has long been nonpartisan. Now an unprecedented meeting of governors over the issue raises the political stakes.

Amazing this piece doesn’t highlight the primary cause of the dwindling river flows - climate change caused mainly by the burning of fossil fuels. www.washingtonpost.com/climate-envi...
