How Responsible Is Climate Change for Increased Wildfires?
“Nearly all” since 2001, according to a new study on California wildfires by the Lawrence Livermore National Laboratory published in the Proceedings of the National Academy of Sciences.
COVID's Extensive 'Excess Mortality'
The pandemic's cumulative death toll in the U.S. does not include over 100,000 fatalities that are directly or indirectly attributable to COVID-19, according to a CDC report released Oct. 20 on the subject of "excess deaths."
One U.S. State Boasts 33% Fewer Carbon Emissions Per Capita Than Any Other
California, the largest state by population in the United States, is responsible for 33% fewer carbon emissions per capita than any other state, according to a new study published in the Proceedings of the National Academy of Sciences.
Clean Water Crisis Exacerbated by Coronavirus
Communities have demanded access to clean water for decades, in some cases. The coronavirus pandemic is compounding the struggle and illustrating the inadequacy of most local government responses.
Another EPA Rollback, Tailor-Made for Gov. Walker and Southeast Wisconsin
Politics and economics win over public health in Racine County as the EPA exempted the area around the Foxconn's massive facility from meeting stricter ozone pollution standards, saving the company from investing in smog-reducing equipment.
The 'Wide-Ranging Ecological Downside' of Road Salt
A study from the USGS using five decades of data shows salinity and alkalinity are up in waterways across the United States.
It's Now Safe to Link Hurricane Precipitation and Climate Change
A new study from MIT makes a clear connection between the intensity of rainfall caused by Hurricane Harvey last August in Texas and climate change, concluding that the likelihood of stronger downpours is greatly increasing.
Middle-Aged White Americans Take a Significant Turn for the Worse
Why are mortality rates increasing for this group in the United States and not others? The usual suspects—obesity, heart disease, diabetes, smoking are not the killers, The findings resulted in the 2015 Nobel Memorial Prize in Economic Science.
Study: 'It's hard to beat gasoline' on Air Quality
A University of Minnesota study published in PNAS looks at alternatives including ethanol and electricity and determined that "it's hard to beat gasoline." Even electric vehicles can do better or worse depending on how utilities source electricity.
Study Complicates Relationship of Population Growth, Emissions Reduction
More people translates to more emissions, right? Cut back on population growth and you'll reduce emissions and the threat of climate change, along with other environmental woes—it's a no-brainer. Or is it?
Pollution from China Doesn't Stay There
A new study reveals two findings on air pollution spewing from China's coal-burning factories. First, the pollution blows to the U.S and other nations. Second, 20% of the pollution can be traced to Western demand for cheap goods from those factories.
EPA has Underestimated Methane Emissions, Study Says
The EPA has seriously underestimated the emissions of the powerful greenhouse gas, methane, particularly from oil and gas activity (five times) and from cattle and livestock operations (two times), according to a new report published in the PNAS.
Is Fracking Less Harmful Than Suspected?
How much methane, a powerful but short-lived greenhouse gas is released during fracking operations for natural gas? Until now, all studies, including those by the EPA, were done by estimates. This study went to over 500 well sites to measure leaks.
Population & Global Warming: Urbanization Increases Emissions
A new study published in the Proceedings of the National Academy of Sciences shows how population growth increases greenhouse gas emissions. More importantly, two demographic factors shape the increase, urbanization and aging -with opposite effects.
