France is hosting world leaders this week to confront what the United Nations calls a global "emergency" in the oceans—but what is expected, and can the summit make a difference?

With careful planning and a little luck, researchers found a surprising upside to hurricanes after a Category 4 storm disrupted their expedition off the coast of Mexico.

Methane emissions from Canada's non-producing oil and gas wells appear to be seven times higher than government estimates, according to a new study led by researchers at McGill University. The findings spotlight a major gap in the country's official greenhouse…

Brazil's environmental goals suffered a major setback in May as deforestation in the Amazon surged 92% compared to the same month last year, according to official monitoring data released Friday.

Antarctica could see a doubling of extreme weather events—such as atmospheric rivers—by 2100, with implications for future sea level rise.

Deep sea sediments contain treasure troves of information about marine ecosystems and past climate scenarios, yet remain understudied clues into Earth's environmental future, according to researchers.

Researchers have developed a laboratory earthquake model that connects the microscopic real contact area between fault surfaces to the possibility of earthquake occurrences. Published in the Proceedings of the National Academy of Sciences, this breakthrough…

Dust particles thrown up from deserts such as the Sahara and Gobi are playing a previously unknown role in air pollution, a new study has found.

Once in a while, scientific research resembles detective work. Researchers head into the field with a hypothesis and high hopes of finding specific results, but sometimes, there's a twist in the story that requires a deeper dive into the data.

Climate change is reshaping the global water cycle, disrupting rainfall patterns and putting growing pressure on cities and ecosystems. Some regions are grappling with heavier rainfall and flooding, while others face prolonged droughts that threaten public…

New research has revealed that construction activity is now a dominant source of black carbon emissions in central London. The research, published in the journal Environmental Sciences: Atmospheres, is the first of its kind in Europe.

Researchers studying harmful algal blooms in the St. Louis River Estuary that separates Minnesota and Wisconsin have made a breakthrough discovery: for the first time, they've linked a known cyanotoxin directly to a specific cyanobacteria species, Microcystis…

Oregon State University researchers are gaining a more detailed understanding of emissions from wood-burning stoves and developing technologies that allow stoves to operate much more cleanly and safely, potentially limiting particulate matter pollution by 95%.

Guatemalan authorities said Thursday they were evacuating more than 500 people after Central America's most active volcano spewed gas and ash.

Droughts are becoming more severe and widespread across the globe. But it's not just changing rainfall patterns that are to blame. The atmosphere is also getting thirstier.

Heat waves, droughts and forest fires are some of the extreme climate-related events that are expected not only to become more frequent but also to increasingly strike at the same time. This finding emerges from a new study led by Uppsala University, in which…

For the first time, the seasonal peak of carbon dioxide concentrations in the atmosphere exceeded 430 parts per million (ppm) at NOAA's Mauna Loa Observatory on Hawaii, scientists from NOAA and Scripps Institution of Oceanography at the University of…

A lot can change in a year for Earth's forests and vegetation, as springtime and rainy seasons can bring new growth, while cooling temperatures and dry weather can bring a dieback of those green colors. And now, a novel type of NASA visualization illustrates…

It is becoming increasingly difficult to produce sufficient drinking water, and this process also releases large amounts of the harmful greenhouse gas methane. For his Ph.D. thesis, microbiologist Alje Boersma researched how we can purify drinking water more…

A new study investigates the environmental factors affecting the occurrence and state of palsa mires, as well as the degradation of palsas. The study covers the entire Northern Hemisphere. The new results are part of a doctoral dissertation by Oona Leppiniemi…
