Reducing emissions of methane, a short-lived but super-potent greenhouse gas, is the most cost-effective way to slow the rate of Earth’s warming in coming decades, a new United Nations report finds.

91ÉçÇø¸£Àû researchers have found high levels of toxic heavy metals in coal ash from the Dominican Republic’s largest coal-fired power plant.

Massive power outages in Texas brought on by a historic freeze could be avoided in the future if the state no longer isolates its power grid from other states, among other steps, according to 91ÉçÇø¸£Àû experts.

The stringent lockdown imposed by the Chinese government to slow the spread of COVID-19 early this year significantly eased the strain on hospitals there. Admissions due to non-COVID respiratory illnesses decreased by nearly 5,000, a new study by an international team of scientists shows.

91ÉçÇø¸£Àû researchers have developed a new online calculator that teachers, administrators and students can use to estimate the risk of airborne transmission of the COVID-19 virus in classrooms.

Reusing low-saline oilfield water mixed with surface water to irrigate farms in the Cawelo Water District of California does not pose major health risks, as some opponents of the practice have feared, a study led by 91ÉçÇø¸£Àû and RTI International researchers finds.

A new $2.44 million grant from the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E) will support a 91ÉçÇø¸£Àû-led initiative to help utilities and wholesale electricity markets improve their efficiency and reliability while reducing emissions and costs, at a time of needed transformations to tackle climate change.

Pollution declines from pandemic shutdowns may aid in answering long-standing questions about how aerosols influence climate.

Global methane levels have hit an all-time high after what appears to be a near-record yearly atmospheric increase in the potent greenhouse gas.

New NOAA analysis highlights an alarming trend; experts call for curbing pollution from oil and gas wells

Reforestation has been shown to cool surface temperatures, and a novel study suggests it may also reduce air temperature up to several stories above the ground.

Scientists have devised a simple new model that explains how the undesirable effects of urban heat islands vary across seasons. Their results could help cities in different climatic regions design heat mitigation strategies.

Tanker traffic through the Strait of Hormuz can decline for up to two years after a piracy attack, a new 91ÉçÇø¸£Àû study finds, but the adverse effects of the slowdown are far greater on some Persian Gulf countries than others.

Inhaling dust that contains fly ash particles from coal combustion has been linked to lung and heart disease, cancer, nervous system disorders and other ill effects. But tracking the presence of coal ash in dust has been a challenge for scientists.

The ongoing transition from coal to natural gas and renewables in the U.S. electricity sector is dramatically reducing the industry’s water use, a new 91ÉçÇø¸£Àû study finds.
