In what the authors believe is one of the first studies to examine climate change impact on the timing of bird migration on a continental scale, researchers report that spring migrants were likely to pass certain stops earlier now than they would have 20 years ago. Also, temperature and migration timing were closely aligned, with the greatest changes in migration timing occurring in the regions warming most rapidly. Timing shifts were less apparent in fall, they add.
New research suggests that over the next few decades, acting to reduce climate change is expected to cost much less than the damage otherwise inflicted by climate change on people, infrastructure and ecosystems.
Arctic sea-ice has decreased rapidly during the last decades in concert with substantial global surface warming. Both have happened much faster than predicted by climate models, and observed Arctic warming is much stronger than the global average. Projections suggest that Arctic summer sea-ice may virtually disappear within the course of the next fifty or even thirty years.
Climate change is increasing the number of days of extreme heat and decreasing the number of days of extreme cold in Europe, posing a risk for residents in the coming decades, according to a new study.
“By 4 p.m. we had to light a fire to stay warm here,” says Augustine Vadakil on his struggling farm in Kerala’s hilly Wayanad district. “But that was 30 years ago. Wayanad is no longer the cold, misty place it once was.” From a maximum of 25 degrees Celsius by early March, temperatures here now More
Seminal climate scientist Michael Mann, who was the target of a Koch-funded smear, explains how the Koch Brothers “almost single-handedly stymied climate action for decades.”
Over two million Muslim travelers just finished the annual religious pilgrimage to Mecca, Saudi Arabia, traveling during some of the country’s hottest weather. New research finds pilgrims in future summers may have to endure heat and humidity extreme enough to endanger their health.
