When communities like San Francisco and Seattle began banning plastic bags, said Ramesh Ponnuru, it seemed like a public-spirited thing to do. But’ benign-seeming laws often have unintended consequences— and the plastic-bag ban is now producing a sickening result. The reusable shopping bags that people now use to bring groceries home turn out to be breeding grounds for bacteria carried […]

A research paper published in Nature Climate Change predicts widespread death of needleleaf evergreen trees (NET) within the Southwest United States by the year 2100 under projected global warming scenarios. The research team that conducted the study, which includes University of Delaware’s Sara Rauscher, considered both field results and a range of validated regional predictions and global simulation models of […]

In its early days, Earth became hell. About 3.3 billion years ago, new research indicates, at least two massive asteroids 30 to 60 miles in diameter smashed into this planet, boiling the oceans and sending atmospheric temperatures soaring to an unimaginable 932 degrees Fahrenheit. Stanford University scientists have found evidence of this extreme era in a geological formation in South […]

The key to helping animals evolve quickly in response to climate change could actually be their predators, according to a new UBC study. The study is one of the first to show that species interactions, meaning the way species interact with each other in an ecosystem, like in a predator-prey relationship, is important to understanding how animals will respond to […]

It’s been five years since the Deepwater Horizon oil rig exploded in the Gulf of Mexico, killing 11 and releasing a torrent of petroleum into the sea. But despite a massive, multibillion-dollar cleanup effort, the effects of the largest marine oil spill in U.S. history may linger for decades. BP (British Petroleum), which operated the rig, has already paid […]

Aerosols, tiny solid and liquid particles suspended in the atmosphere, impact the environment by affecting air quality and alter the Earth’s radiative balance by either scattering or absorbing sunlight to varying degrees. What impact does climate change, induced by greenhouse gases (GHGs), have on the aerosol “burden”–the total mass of aerosols in a vertical column of air? Past research done […]

A new study has found the strongest link yet between air pollution and autism, which experts now say affects one in 50 U.S. schoolchildren. Pregnant women who lived in areas with high levels of diesel exhaust and airborne mercury were found to be twice as likely to have a child with autism as those living in places with the lowest […]

The amount of plastic garbage in the North Pacific Ocean has risen a hundredfold since the 1970s, and the floating debris is now so abundant that marine life is adapting to its presence. Researchers from the Scripps Institution of Oceanography sampled an expanse of the sea between Hawaii and California, where currents tend to deposit flotsam from around the Pacific […]

UK researchers have unearthed ancient fossil forests, thought to be partly responsible for one of the most dramatic shifts in Earth’s climate in the past 400 million years. The fossil forests, with tree stumps preserved in place, were found in Svalbard, a Norwegian archipelago situated in the Arctic Ocean. They were identified and described by Dr Chris Berry of Cardiff […]

Historic drought: Broiling heat baked much of the U.S. heartland this week, as the nation’s worst drought in more than 50 years devastated corn, soy, and other vital crops. More than 1,000 counties in 26 states have been declared natural disaster areas and 38 percent of the nation’s corn crop is in danger of withering in the field, the U.S. […]
