Queen Elizabeth has no patience for plastic.

Here’s how humanity could all but ensure its own demise: Dig up all the coal we have left and burn it, warming the planet 4 to 6 degrees C.

But that worst-case scenario doesn’t match up with what’s really happening in the world, Justin Ritchie, lead author of a new study published in Environmental Research Letters, told Grist.

That’s because money spent on climate change measures goes further than it did 30 years ago. Plus, baseline trends show greenhouse gas emissions are on the decline. Most studies underestimate the effect these factors have on global decarbonization.

The study indicates that the goals outlined in the Paris Agreement are more achievable than previously projected — but that’s not to say humanity isn’t in deep trouble.

It’s not “4 to 6 degrees bad,” Ritchie says. “It’s 3 degrees bad. You can’t say we don’t have to worry about implementing policies, we do. But it’s not going to reach the truly catastrophic scenarios.”

Another recent study published in the same journal shows that if all the coal plants currently planned actually get built, humanity could blow past the Paris goal of limiting warming to 2 degree C above pre-industrial levels.

Ritchie said his research doesn’t counteract that finding. “There’s a whole range of scenarios that can occur,” he says. “What our paper is trying to do is look at that whole range and how can we design policies that are more robust.”

The EPA hired a ‘war room’-style media monitoring company.

Forests in the American West are having a harder time recovering from wildfires because of (what else?) climate change, according to new research published in Ecology Letters.

Researchers measured the growth of seedlings in 1,500 wildfire-scorched areas in Colorado, Wyoming, Washington, Idaho, and Montana. Across the board, they found “significant decreases” in tree regeneration, a benchmark for forest resilience. In one-third of the sites, researchers found zero seedlings.

The warmest, driest forests were hit especially hard.

“Seedlings are more sensitive to warm, dry conditions than mature trees, so if the right conditions don’t exist within a few years following a wildfire, tree seedlings may not establish,” said Philip Higuera, a coauthor of the study.

Earlier this month, a separate study found that ponderosa pine and pinyon forests in the West are becoming less resilient due to droughts and warmer temperatures. Researchers told the New York Times that as trees disappear, some forests could shift to entirely different ecosystems, like grasslands or shrublands.

You’d think the rapid reconfiguration of entire ecosystems would really light a fire under us to deal with climate change, wouldn’t you?

We’re Pumping So Much Groundwater That It’s Causing the Oceans to Rise

Pump too much groundwater and wells go dry—that’s obvious.

But there is another consequence that gets little attention as a hotter, drier planet turns increasingly to groundwater for life support.

So much water is being pumped out of the ground worldwide that it is contributing to global sea level rise, a phenomenon tied largely to warming temperatures and climate change.

It happens when water is hoisted out of the earth to irrigate crops and supply towns and cities, then finds its way via rivers and other pathways into the world’s oceans. Since 1900, some 4,500 cubic kilometers of groundwater around the world—enough to fill Lake Tahoe 30 times—have done just that.

Geophysical Research Letters

“Long-term groundwater depletion represents a large transfer of water from the continents to the oceans,” retired hydrogeologist Leonard Konikow wrote earlier this year in one article. “Thus, groundwater depletion represents a small but nontrivial contributor to SLR sea-level rise.”

Sea levels have risen 7 to 8 inches since the late 19th century and are expected to rise more rapidly by 2100. The biggest factors are associated with climate change: melting glaciers and other ice and the thermal expansion of warming ocean waters.

Groundwater flowing out to sea added another half-inch—6 to 7 percent of overall sea level rise from 1900 to 2008, Konikow reported in a 2011 article in Geophysical Research Letters. “That really surprised a lot of people,” he said in a recent interview with Reveal.

Konikow also has reported that 1,000 cubic kilometers—twice the volume of Lake Erie—were depleted from aquifers in the US from 1900 to 2008, and the pace of the pumping is increasing.

Geophysical Research Letters

In California, so much groundwater has been pumped from aquifers in parts of the San Joaquin Valley that the land itself is starting to sink like a giant pie crust, wreaking havoc with roads, bridges and water delivery canals.

Not only is groundwater growing scarce, but we’re pumping out older and older water. In parts of California, cities and farms are tapping reserves that fell to Earth during a much wetter climatic regime—the ice age, a phenomenon that Reveal covered earlier this month and which raises questions about future supplies as the climate turns drier.

Last week, NASA senior water scientist Jay Famiglietti warned that “the state has only about one year of water supply left in its reservoirs, and our strategic backup supply, groundwater, is rapidly disappearing.”

According to Konikow, groundwater overdraft in the US accounted for about 22 percent of global groundwater depletion from 1900 to 2008, contributing about an eighth of an inch to global sea level rise.

Meet perfluorotributylamine, the world’s worst greenhouse gas

Meet perfluorotributylamine, the world’s worst greenhouse gas

What synthetic compound has 27 fluorine atoms, a dozen carbon atoms, and a dash of nitrogen? The world’s worst known greenhouse gas.

A class of compounds known as perfluoroalkyl amines have been manufactured for more than 50 years for use by the electronics industry. Climate scientists don’t know much about them, but they have been worried for some time that they could be affecting the climate. And a new study, published in the journal Geophysical Research Letters, seems to have confirmed some of their worst fears.

National Institute of Standards and TechnologyJust call it PFTBA.

Scientists at the University of Toronto studied one such compound, perfluorotributylamine, and concluded that it could persist in the atmosphere, trapping heat here on Earth, for more than 500 years. Not only that, but the scientists concluded in their paper that it has the “highest radiative efficiency of any compound detected in the atmosphere.”

Researcher Angela Hong said that over a century a single molecule of PFTBA, as it is catchily called, has an “equivalent climate impact” of more than 7,000 carbon dioxide molecules.

Next up: Figuring out what the other perfluoroalkyl amines are doing to the climate, and searching for climate-friendlier chemicals that could be used instead. As Hong and her colleagues dryly note in their paper, “Detection of PFTBA demonstrates that perfluoroalkyl amines are a class of [long-lived greenhouse gas] worthy of future study.”

UPDATE, from The Guardian:

Concentrations of PFTBA in the atmosphere are low — 0.18 parts per trillion in the Toronto area — compared to 400 parts per million for carbon dioxide. So PFTBA does not in any way displace the burning of fossil fuels such as oil and coal as the main drivers of climate change.

Dr Drew Shindell, a climatologist at Nasa’s Goddard Institute for Space Studies, said: ”This is a warning to us that this gas could have a very very large impact on climate change — if there were a lot of it. Since there is not a lot of it now, we don’t have to worry about it at present, but we have to make sure it doesn’t grow and become a very large contributor to global warming.”

Readers to papers: Stop publishing letters that deny climate reality

Readers to papers: Stop publishing letters that deny climate reality

Newspapers should be truthful. That goes for every single page.

The L.A. Times recently won national attention and praise for spelling out its policy of refusing to publish the claims of climate deniers.

“Letters that have an untrue basis (for example, ones that say there’s no sign humans have caused climate change) do not get printed,” the letters page editor wrote.

Now, readers of other major newspapers are calling on their favored media outlets to adopt the same policy.

Forecast the Facts, a project that aims to improve the quality of coverage of climate change in the press, launched a petition calling on the New York Times, Washington Post, USA Today, and Wall Street Journal to refuse to print letters that deny basic science.

“The Los Angeles Times has adopted a policy of refusing to publish letters that deny climate change, and you should follow suit,” the petition states. “End climate change denial in your newspaper.”

On Monday, the group told The Hill that it had already gathered 22,000 signatures in less than a day.

Italy makes huge haul of mafia assets in green energy case

hh

<!– google_ad_section_start –> Italy made its biggest confiscation of mafia assets in history on Wednesday, including dozens of alternative energy companies worth a total of 1.3 billion euros (HK$12.96 billion), police said. A court in Trapani on the island of Sicily ordered the definitive confiscation of assets first seized in 2010 from Vito Nicastri, a 57-year-old businessman, who was deemed a front man for the Sicilian mafia, known as Cosa Nostra. <!– google_ad_section_end –>
