Analysis
New research shows that humans have been transforming the earth and its ecosystems for millenniums — far longer than previously believed. These findings call into question our notions about what is unspoiled nature and what should be preserved.
Analysis
A consensus is emerging among scientists that the rate of global warming has slowed over the last decade. While they are still examining why, many researchers believe this phenomenon is linked to the heat being absorbed by the world’s oceans.
Analysis
Fishways on rivers in the U.S. Northeast are failing, with less than 3 percent of one key species making it upriver to their spawning grounds, according to a new study. The researchers’ findings provide a cautionary tale for other nations now planning big dam projects.
Analysis
An expanding body of evidence shows that the presence of field biologists and their assistants is playing an important part in deterring poaching, illegal logging, and other destructive activities in the world’s parks and wildlife reserves.
Analysis
The world’s largest living species, native to California’s Sierra Nevada, faces a two-pronged risk from declining snowpack and rising temperatures. The threat to sequoias mirrors a growing danger to trees worldwide, with some scientists saying rapid warming this century could wipe out many of the planet’s old trees.

Blocked Migration: Fish Ladders On U.S. Dams Are Not Effective
Fishways on rivers in the U.S. Northeast are failing, with less than 3 percent of one key species making it upriver to their spawning grounds, according to a new study. The researchers’ findings provide a cautionary tale for other nations now planning big dam projects.

Giant Sequoias Face Looming Threat from Shifting Climate
The world’s largest living species, native to California’s Sierra Nevada, faces a two-pronged risk from declining snowpack and rising temperatures. The threat to sequoias mirrors a growing danger to trees worldwide, with some scientists saying rapid warming this century could wipe out many of the planet’s old trees.
