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).
"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.
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.
Three of the biggest U.S. oil companies pledged $300 million toward research into lowering climate-change pollution as they joined an industry group led by European rivals. will join the Oil & Gas Climate Initiative and expand an existing $1 billion fund for carbon-reduction ventures, the group said on Sept.
Stock said the government had already done the work required to “put these greenhouse gas emissions standards in place for vehicles and bring Australia in line with 80% of the global car market”.
According to the New York Times report, the US Environmental Protection Agency is set to relax a series of rules on methane emissions currently imposed on the US oil and gas industry, including a reduced frequency in checking for leaks and an extended grace period before repairs must be made.
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 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.
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.
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.
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.
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.
If you work in reef conservation, it’s hard to miss the stories of coral bleaching. Why is Sewage Pollution a Significant Threat to Coral Reefs? The last thing we should be doing is giving up on coral reefs.
The other piece of climate change that is just beginning to affect coral reefs is ocean acidification. Warm water coral reefs and climate change.
