Polar Vortex, Warming Paradox
By Dr. Anne Waple, Director of Communication and Science at Second Nature
If you're among the 200 million Americans who have been experiencing our recent, let's just say, chilly conditions, then you might be wondering if global warming has suddenly come to a screeching halt. Well, it turns out that far from being an indicator of a slow-down in global climate change, it's one more piece of evidence for increasing climate instability as a result of human-induced warming.
Linked to a decrease in sea ice extent and increased warming in the Arctic, the recent intrusion of very cold air into the continental U.S. is a result of the polar vortex weakening and allowing Arctic air to flow south. The polar vortex is the circulation pattern that typically fences cold air into the Arctic. Below are several excellent descriptions of this phenomenon and its link to a warming planet.

While this recent event is not record-breaking for most of us and will be thankfully short-lived, it has caused significant impacts across much of the country, closing schools and businesses, shutting down transportation, interrupting power for some residents, and prompting emergency declarations in several cities and communities.

approaching a 50 percent overall reduction in energy intensity achieved through a comprehensive program of deep energy efficiency, as a result of their “Smart Labs” program. Only a few years ago, no one believed that efficiency improvements and retrofits would yield a major percentage of needed carbon abatement, because the efficiency gains of new technologies - particularly sensors, digital controls, and software – were underestimated. All of those are key elements in UCI's comprehensive “Smart Labs” retrofit program. 


announced her intent to bring the University to net energy neutrality by 2025. This bold plan builds on the reduction in carbon emissions that all campuses of the UC system have made as signatories to the American College & University Presidents’ Climate Commitment (ACUPCC) and demonstrates the true transformation that can result from higher education leadership. At Second Nature, we are looking forward to continuing to work with the campuses of the University and President Napolitano’s chancellors and staff as they implement this inspiring initiative.

Haywood Community College (HCC) has a rich history of sustainability. When President Rose H. Johnson arrived in January 2006 she made sure sustainability was a strategic imperative for the college. In May of 2007 President Johnson signed the ACUPCC, committing HCC to the far-reaching goal of eliminating its operational greenhouse gas emissions, supporting the educational opportunities for students to advance a low carbon society and to publicly report progress on an annual basis. To support the goals of the ACUPCC and other sustainability efforts, HCC also joined AASHE, participates in AASHE's
Starting in 1990, Ball State University began its “dance” with the challenges of sustainability. At that time, the Provost and Vice President for Academic Affairs, Dr. Warren Vander Hill, appointed our first Green Committee (
