Issues like the Medieval
warm period, different possible causes of climate change (such as solar activity, or even the nature of our climate), studies indicating the last interglacial period was
warmer than today, and the failure of recent dire predictions about the climate all show the debate on climate change is not nearly as settled as many
global warming proponents would have us
believe.
This is sound and well established science and is relied by upon the
proponents of Anthropogenic
Global Warming (AGW) to explain why they
believe the Earth is
warmed by human emissions of Greenhouse Gases (GHGs) to a temperature higher than it would be if we were not releasing emissions.
