More than 80 percent of all waste from Pennsylvania’s oil and gas drilling operations stays inside the state, according to a new study that tracks the disposal locations of liquid and solid waste from these operations across 26 years.

To assess differences and trends in personal chemical exposure, Oregon State University researchers deployed chemical-sampling wristbands to individuals on three continents.

Nine years ago tomorrow—April 20, 2010—crude oil began leaking from the Deepwater Horizon drilling rig into the Gulf of Mexico in what turned out to be the largest marine oil spill in history.

Farmers rely on phosphorus fertilizers to enrich the soil and ensure bountiful harvests, but the world’s recoverable reserves of phosphate rocks, from which such fertilizers are produced, are finite and unevenly distributed.

Of all the different possible methods to combat anthropogenic climate change conceived of so far, among the least studied is climate engineering.

A UT professor and expert known for his work on the Deepwater Horizon oil spill recovery efforts has co-authored a report making a series of recommendations to federal agencies on how to safely clean up after spills.

Microplastics have been found in some of the most remote aquatic ecosystems on earth, including in the deepest parts of the ocean.

From 2011 to 2015, California experienced its worst drought on record, with a parching combination of high temperatures and low precipitation.

From campaigns against microplastics to news of the great Pacific garbage patch, public awareness is growing about the outsized effect plastic has on the world’s oceans.

Thawing permafrost in the Arctic may be releasing 12 times as much nitrous oxide as previously thought, according to a new study published in the journal Atmospheric Chemistry and Physics.Nitrous oxide, a powerful greenhouse gas 300 times more potent than carbon dioxide, can remain in the atmosphere for up to 114 years, according to the U.S. Environmental Protection Agency (EPA).
