Damages wrought by climate change and deforestation have transformed the Amazon rainforest. New research suggests the changes to this icon of the natural world caused by human activity may mean the Amazon now emits more greenhouse gases than it absorbs.

The Amazon Rainforest Now Emits More Greenhouse Gases Than It Absorbs

Climate change and deforestation have transformed the ecosystem into a net source of planet-warming gases instead of a carbon sink

Colorado's two largest fires in state history seen from space via Landsat 8. The Cameron Peak fire is on the upper right and the East Troublesome fire is on the lower left; the fires have burned more than 190,000 and 200,000 acres, respectively.

Colorado's Record-Breaking Blazes Illustrate the West's Lengthening Fire Season

Fire season is usually over by this time in October, but, in a trend experts expect climate change to exacerbate, that's not the case this year

California reached another devastating milestone this year: four million acres in total have been burned so far this fire season, more than doubling the state’s previous record from 2018’s Mendocini Complex Fire.

Experts say that climate change will decimate the population of Joshua trees, but California is taking action

When Alexander von Humboldt (right) traveled to England in 1790, he met a young chemist named James Smithson, the founder of the Smithsonian. Humboldt's influence still resonates throughout the massive museum and research complex.

How the Revolutionary Thinker Alexander von Humboldt Helped to Create the Smithsonian

The 19th-century polymath continues to influence the Institution’s research; a major Smithsonian exhibition explains how and why

Smithsonian researchers studied 67 forest plots in a section of the Blue Ridge Mountains. They found that hemlock woolly adelgid had decimated hemlock populations.

Smithsonian researchers with ForestGEO found that invasive species are linked to roughly one in four tree deaths in a section of the Blue Ridge Mountains

Coyotes are about to enter South America, a move that could soon make the species, native to North America, one of the most widespread carnivores in the western hemisphere.

Coyotes Poised to Infiltrate South America

The crab-eating fox and the coyote may soon swap territories, initiating the first American cross-continental exchange in more than three million years
