6 WORST DENIER MYTHS ABOUT GLOBAL CLIMATE INSTABILITY

From Dan Mustarde:
Polar Ice is Growing
The shrinking ice caps have been the cornerstone of many climate debates, but recent reports show that Antarctic sea ice has actually extended by record amounts in the past year.
So here’s where things get tricky. Sea ice and continental ice are vastly different things. Continental ice is ancient ice that is hundred to thousands of meters thick. Sea ice is thin, unstable ice that moves with the currents and mass together through collisions.
Continental ice plays a pivotal role in climate change because ancient ice can’t be replaced when it melts. Locked in as land ice, when continental ice melts it causes sea levels to rise. Sea ice forms and melts with the seasons, so while sea ice extensions are a good thing they aren’t likely to last. http://www.onegreenplanet.org/animalsandnature/the-5-worst-myths-about-global-climate-change-busted/
