Could global warming change tornado season, too?
With the planet heating up, many scientists seem fairly certain some weather elements like hurricanes and droughts will worsen. But tornadoes have them stumped.
Monsoon failure key to long droughts in Southwest
Long-term droughts in the Southwestern North America often mean failure of both summer and winter rains, according to new tree-ring research from a University of Arizona-led team.
Amplified greenhouse effect shaping North into South
An international team of 21 authors from 17 institutions in seven countries has just published a study in the journal Nature Climate Change showing that, as the cover of snow and ice in the northern latitu ...
Tree die-off triggered by hotter temperatures
A team of scientists, led by researchers at Carnegie's Department of Global Ecology, has determined that the recent widespread die-off of Colorado trembling aspen trees is a direct result of decreased precipitation exacerbated ...
Drought does long-term damage to rainforest
Recent droughts in the Amazon rainforest have effects that persist long after the rains have returned, a new study has shown.
Scientific paper challenges assumptions about bark beetles' link to wildfires
Don't blame bark beetles for catastrophic wildfires such as the blaze that blackened more than 23,000 acres of Kittitas County in Washington state last summer, some scientists say.
Study provides new insights on drought predictions in East Africa
