The Arctic is warming over twice as fast as the rest of the globe and sea ice cover is plummeting. "We are seeing these events occurring more frequently as of late," said Jeff Weber, a meteorologist with the University Corporation for Atmospheric Research.Īlthough this increase in polar vortex frequency is a hot area of study, one emerging theory blames significantly diminished Arctic sea ice. The polar vortex has become a popular phenomenon for good reason: This weakening of the polar vortex and the subsequent spillover of frigid air has become more common over the last two decades. The polar vortex returned, this time with the coldest temps of the year The results of a new survey - conducted in November 2018 by the University of Chicago's Energy Policy Institute and the research organization The Associated Press-NORC Center for Public Affairs Research - found that nearly half of Americans said today's climate science "is more convincing than five years ago, with extreme weather driving their views." 5.
Extreme weather - not politicians - convinces Americans that climate change is realĪmericans find today's climate science increasingly convincing, and a damaging mix of exceptional drought, storms, and record-breaking heat is the reason why. "As farmers are increasingly exposed to new climate conditions and changing pest pressures, the genetic diversity of wild crop relatives may be essential to breeding new coffee varieties that can withstand these pressures," Nathan Mueller, an assistant professor of earth system science at the University of California, Irvine who researches global food security, said over email. While this hasn't yet imperiled the world's coffee supply, it jeopardizes your favorite coffee's resiliency in the face of profound planetary change.
