Frequently Asked Questions
Is the Ozone Hole Related to Climate Change?

Both the destruction of the ozone hole over the southern hemisphere and the warming of Earth's climate are caused by changes in the composition of the atmosphere due to emissions from human activities. The ozone hole is a place in the stratosphere where ozone has been destroyed by manmade chemicals, mainly chlorofluorocarbons (CFCs). In fact, CFCs also contribute to global warming by trapping heat in the atmosphere...read more (html pdf )

Is Antarctica Experiencing Changes in Climate?

Previous studies have noted a warming over the Antarctic Peninsula while noting a slight cooling over the continent's interior. However, a recent study which blended satellite measurements and automated surface weather station observations conclusively shows a significant warming over most of western Antarctica. This positive trend in temperatures over western Antarctica exceeds 0.1C per decade over the past 50 years. More importantly, these trends are in agreement with climate models...read more (html pdf )

Is There Concensus Among Leading Scientists that Climate Change is Occurring?

There is actually a consensus in the scientific community not only that the earth is getting warmer, but that this trend is anthropogenically driven, and that if greenhouse gas emissions continue, so will the warming. There are, of course, a few skeptics in the scientific community, but the overwhelming majority agree with this core set of principles...read more (html pdf )
