River Pollution Threatens Australia’s Great Barrier Reef

River Pollution Threatens Australia’s Great Barrier Reef

Northern Australia’s torrential wet-season rains carve 10-meter-deep gullies into the landscape, washing an estimated 17 million tonnes of sediment each year into the rivers and, eventually, out onto the Great Barrier Reef (GBR).

Is California's Smoke Getting Worse? It's Complicated

"If you use intensity as a proxy for pollution—that is, if you assume stronger fires will produce more emissions like smoke—then by stint of that, yes, there ought to be more smoke," says atmospheric composition scientist Mark Parrington.A senior researcher at the Copernicus Atmosphere Monitoring Service, Parrington tracks wildfires around the world to better understand their effect on pollution and public health.

The green growth crossroads: changing course to fight climate change in Lao PDR

Green growth means reducing dangerous air and water pollution that harm human health, ensuring sustainable expansion of the power sector, managing river basins, making agriculture and infrastructure more resilient, and better protecting natural heritage, including Lao PDR’s rich and globally important wildlife.

EPA, the Supreme Court affirmed that greenhouse gases qualify as air pollutants, and EPA therefore has authority to regulate them if the agency determines that they may endanger public health or welfare.

The E.P.A.’s Review of Mercury Rules Could Remake Its Methods for Valuing Human Life and Health

The E.P.A.’s Review of Mercury Rules Could Remake Its Methods for Valuing Human Life and Health

The formulas are complex, but the bottom line is that reducing the emphasis on health makes it tougher to justify a rule.Last week the Trump administration took a crucial step toward de-emphasizing the life and health benefits in this calculus when the Environmental Protection Agency said it would rethink a major regulation that restricts mercury emissions by coal-burning power plants.

E.P.A. to Reconsider Obama-Era Curbs on Mercury Emissions by Power Plants

That rule would have restricted coal plants’ emission of a different pollutant: carbon dioxide, one of the chief causes of global warming.At the time the Obama administration put forth the mercury regulations, which took more than 20 years to formulate, E.P.A. officials estimated they would save thousands of lives and return economic and health benefits many times their estimated $9.6 billion annual cost.While owners of coal plants fought the rule in the courts, most have since complied with regulation.

Weatherwatch: Charles Keeling's CO2 curve shows drastic rise in 60 years

His first measurements in 1958 showed 315 parts per million (ppm) of CO2 in the atmosphere, and what caught him by surprise was that every year after that the levels of CO2 rose relentlessly in an upward curve, thanks to the carbon pollution pumped into the Earth’s atmosphere.

Wildfire Smoke Is Smothering the US—Even Where You Don't Expect It

By 2050, an estimated 83.7 million people over the age of 65 will call the US home, nearly doubling the current population—and a paper published in April found that bad smoke days during California’s 2015 wildfire season caused spikes in emergency room visits, with the most pronounced impact on patients over 65.

Your Tweets Can Help Map the Spread of Wildfire Smoke

In a recently published study, US Forest Service researchers Sonya Sachdeva and Sarah McCaffrey found that, when analyzed in large numbers, tweets about wildfires can accurately model the way smoke moves.In their study, published by the International Conference on Social Media & Society, Sachdeva and McCaffrey analyzed close to 39,000 tweets posted between May and September 2015 in California.

President Proposes Unwinding Coal-Plant Pollution Curbs

President Donald Trump’s administration on August 21 unveiled its plan to dramatically weaken carbon dioxide limits on coal-fired power plants by shifting most of the regulatory burden to states in a further assault on the Obama climate legacy.
