A new study makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch known as the Anthropocene.

���ӽ紫ý Today spoke with Louise Chawla about how children are happier and more likely to protect the natural world when they have a greater connection to it, and the important role of social and emotional support from parents, peers and community in creating hope around issues like climate change.

While today's fires are exacerbated by dry conditions, ���ӽ紫ý researchers found that forest fires 94 million years ago occurred even in wet regions due to changes in global climate.

Increasing fishing too quickly can cause coral reef ecosystems to collapse, new ���ӽ紫ý-led research finds.

Arctic sea ice has likely reached its minimum extent for the year, at 3.74 million square kilometers (1.44 million square miles), according to scientists at the National Snow and Ice Data Center. This is the second lowest extent in the nearly 42-year satellite record.

Ever wonder why some fireflies flash in harmony? New research sheds light on this beautiful phenomenon and strives to understand how relatively simple insects manage to coordinate such feats of synchronization.

New ���ӽ紫ý-led research finds the traits that make vertebrates distinct from invertebrates were made possible by the emergence of a new set of genes 500 million years ago.

People are starting almost all the wildfires that threaten U.S. homes, according to an innovative new analysis combining housing and wildfire data.

Volcanic ash shuts down air traffic and can sicken people. But a new study suggests it may also be more important for Earth's climate than once thought.

Three ���ӽ紫ý faculty are principal investigators on a new five-year, $6.9 million National Science Foundation grant to study the “critical zone”—from Earth’s bedrock to tree canopy top—in the American West.
