EPA rolls back Obama-era coal pollution rules as Trump heads to West Virginia

CNN)As his Environmental Protection Agency delivers its latest blow to environmental regulations aimed at reducing carbon emissions, President Donald Trump is heading into the heart of coal country to deliver the good news.

Trump will join supporters in Charleston, West Virginia, for a political rally on Tuesday to celebrate his administration's proposal to allow states to set their own emissions standards for coal-fueled power plants.
The move would reverse Obama administration efforts to combat climate change and marks the fulfilment of a campaign promise at the heart of his appeal in coal-producing states like West Virginia.
The EPA Tuesday morning formally unveiled the details of its new plan to devolve regulation of coal-fired power plants back to the states, one that is expected to give a boost to the coal industry and increase carbon emissions nationwide.
The move is just the latest effort by the Trump administration to revive an ailing coal industry and strip climate change-fighting regulations established by the Obama administration. He previously announced plans to withdraw from the Paris climate accords, calling it an unfair deal for Americans. Read More

Nearly Half the World’s Trash Is Burned, and That’s Worsening Climate Change

Nearly half the world’s trash is burned in the open, spewing pollutants into the atmosphere that contribute to climate change and affect human health, according to a new study.

Since such burning is largely unregulated and unreported, emissions of some pollutants have been underestimated by as much as 40 percent, said the researchers, who published their findings in the journalEnvironmental Science & Technology.

"I was shocked at the numbers," said Christine Wiedinmyer, an atmospheric scientist at the National Center for Atmospheric Research and the study’s lead author. "They were much larger than I expected, particularly the air pollutants."

The researchers estimated the amount of carbon dioxide, carbon monoxide, mercury, tiny particulate matter, and other pollutants released by burning trash.

Every year 970 million metric tons of food, paper, plastics, and metals are set aflame at homes, businesses, and dumps—roughly 41 percent of the world’s garbage, according to the study.

The garbage problem is likely to get worse. Researchers predict the world will triple its production of garbage to more than 11 million tons daily by 2100.

Fires can spring up at dumps with little warning. A fire in Iqaluit, the capital of the Canadian territory of Nunavut, broke out in May and burned for almost 100 days before fire crews began dousing the flames of the "dumpcano." In March, a dump fire outside Bangkok blanketed neighborhoods with so much thick smoke that it could be seen by satellites.

Heavily populated countries, including China, the United States, India, Japan, Brazil, and Germany, produce the most waste, according to the study. China, India, Brazil, Mexico, Pakistan, and Turkey generate the most emissions from trash burning.

Trash burning produces mercury, chemicals known as polycyclic aromatic hydrocarbons, and fine particulate matter. These pollutants have been linked to heart and lung disease, neurological disorders, and cancer. Annual emissions of mercury and PAHs may have been underestimated by 10 to 40 percent, the researchers said.

Trash burning may also be clogging the air with far more particulate matter than was previously thought. A global tally of reported pollutants indicated that 34 million kilograms of tiny airborne particles called PM 2.5 are released into the air annually.

Wiedinmyer and her colleagues calculate that open burning shoots another 10 million kilograms into the atmosphere—an increase of 29 percent. In Sri Lanka, garbage burning produced five times more emissions of PM 10 (a larger particle) than was included in the official national tally.

These particles can penetrate deep into the lungs and have been associated with heart disease, asthma, and premature death. About 3.7 million people die prematurely from outdoor air pollution, according to the World Health Organization.

Open burning of garbage is closely related to poverty. Unregulated dump fires may be adjacent to settlements, putting the families that live there, especially women and children, at risk of health complications from the pollution. Some of these families derive income from the dump, removing valuable materials for resale.

The contribution of garbage burning to global carbon dioxide emissions is relatively small—only 5 percent of the 2010 global annual emissions. But on a country-by-country basis, it can be quite large. The study found that trash burning in Lesotho, Burundi, Mali, Somalia, and Sri Lanka produced more carbon dioxide than was recorded by the official registers.

Emissions from open burning of trash are rarely reported by environmental agencies, meaning the pollution goes uncounted and is left out of policy decisions.

Air Pollution Isn’t Just Bad for Your Health—It’s Taking Food off Your Plate

Brian Gullett, an environmental engineer at the United States Environmental Protection Agency and a coauthor of the paper, pointed out how difficult it is to calculate the emissions that come from open burning. Unlike with coal-burning power plants, no one knows the exact number of garbage-burning fires, and it can be difficult to trap and analyze the emissions.

Knowing where pollutants come from doesn’t change the burden they place on health, said Patrick Kinney, an expert on health and air pollution at Columbia University. But it does point to "which sources to go after in controlling the problem."

Said Wiedinmyer, "If we’re looking at air pollution control strategies, we need to include all sources of air pollutants to get the most effective controls in place. If we’re missing a large source, it could lead to control strategies that aren’t going to work at all, or as well." More

Arctic seas turn to acid, putting vital food chain at risk

With the world's oceans absorbing six million tonnes of carbon a day, a leading oceanographer warns of eco disaster

Sunday 4 October 2009 - Carbon-dioxide emissions are turning the waters of the Arctic Ocean into acid at an unprecedented rate, scientists have discovered. Research carried out in the archipelago of Svalbard has shown in many regions around the north pole seawater is likely to reach corrosive levels within 10 years. The water will then start to dissolve the shells of mussels and other shellfish and cause major disruption to the food chain. By the end of the century, the entire Arctic Ocean will be corrosively acidic.

"This is extremely worrying," Professor Jean-Pierre Gattuso, of France's Centre National de la Recherche Scientifique, told an international oceanography conference last week. "We knew that the seas were getting more acidic and this would disrupt the ability of shellfish – like mussels – to grow their shells. But now we realise the situation is much worse. The water will become so acidic it will actually dissolve the shells of living shellfish." More >>>
