If you haven't heard of 'Climategate,' then please consider these posts simply informed perspective of the science of climate change. But if you have heard of the climate skeptics who hacked scientists emails in order to "prove" that anthropogenic (human-made) climate change is a fallacy, I'd like to point you to a couple of scientific rebuttals.
First, watch Rajendra Kumar Pachauri, president of the Intergovernmental Panel on Climate Change, speak out in Copenhagen at the United Nations Framework Convention on Climate Change against the media frenzy that is 'climategate.'
Then, check out an enlightening YouTube video that brings to light that scientific and statistical terminology has a different meaning (re: trick), and that proxy data from tree rings is not the same as data from the instrumented record (re: hide the decline).
Finally, another scientists' blog that discusses the findings and truth behind "climate-gate."
PRI accepts the scientific consensus of the IPCC that humans are contributing to the warming of this planet through the combustion of carbon dioxide through fossil fuel use, among many other contributors like deforestation and land use.
