Fish can't read maps, and their eggs and larvae drift across national boundaries. Recent research shows that local problems in one fishery can affect others across wide areas.
Big storms with lots of flooding, like hurricanes Dorian and Maria, actually restore the Caribbean's delicate balance between native and nonnative fish species, new research finds.
Carbon dioxide makes up less than one-twentieth of 1% of Earth's atmosphere. How does this relatively scarce gas control Earth's thermostat?
The United Nations is calling on world governments to step up action against climate change. Can China, the world's biggest carbon emitter, fulfill its pledges?
The typical American's annual household carbon footprint is over five times the world per capita average.
Should lakes, rivers and other resources have legal rights? New Zealand, Ecuador and other countries have taken this step. Now Toledo, Ohio is a US test case.
Conservatives worldwide favor carbon pricing, cap-and-trade systems and other innovative environmental plans – just not in the United States.
As deforestation rates in Brazil rise, it's worth asking whether the country can repeat the successes of the last decade. Current trends don't bode well.
Poverty and violence are often cited as the reasons people emigrate from Central America, but factors such as drought, exacerbated by climate change, are driving people to leave too.
A recent survey in Indiana finds broad concern about climate change and support for addressing it in this red state, with one catch: Many Hoosiers don't realize their neighbors agree with them.
Social media make it easier to push information out quickly during disasters, but also create challenges for public information officers, who have to judge which reports are credible enough to share.
Two energy scholars who have studied the extent of methane leaks in the oil and gas industry explain what rescinding methane emissions regulations will mean to the climate and industry.
Newark is the latest US city to struggle with high lead levels in drinking water. Ending this public health crisis will require more money and enforcement, plus stricter water testing standards.
If the Amazon rainforest functions as our planet's lungs, what do raging wildfires threaten? An atmospheric scientist explains why the fires, though devastating, won't suffocate life on Earth.
Feral pigs are a destructive invasive species across much of North America. In a recent study, forest patches where feral pigs were present had fewer mammal and bird species than swine-free zones.
InterContinental Hotels Group plans to switch miniature toiletries for bulk products, but it isn't likely to do as much for the environment as activists might think.
Don't blame climate change for the 39,000 forest fires now incinerating huge tracts of the Brazilian Amazon. This environmental catastrophe is human-made and highly political.
We have all the technologies needed to make the electric grid run on renewables and lower pollution. What are they and what are the barriers to adopting them widely?
Some climate scientists have spoken out about the dangers of climate change. But a new study shows those voices may not be very influential.
As the oceans warm, fish are moving to stay in temperature zones where they have evolved to live. This is helping some species, hurting others and causing a net reduction in potential catch.
A researcher based in Fairbanks, Alaska, links 2019's record-breaking wildfires in far northern regions of the world to climate change, and describes what it's like as zones near her city burn.
Climate change threatens the water supply of nations around the world. But it's difficult to measure whether a region has sufficient water to satisfy the people who live there. Could satellites help?
More than one-fifth of global warming emissions come from land use. Sustainable farming can make soil healthier and better able to soak up carbon, while saving energy and boosting food production.
The Trump administration is changing implementation of the Endangered Species Act in ways that conservationists say would reduce protection for some of America's most threatened wildlife.
A new report calls land key to solving climate change. The good news is that there are strategies for reducing carbon emissions from land use that can also produce economic and social benefits.
