Hello there! If you are new here, you might want to subscribe to the RSS feed for updates on this topic.

So much for that hockey-stick graph:

What this graph shows is the presence of a Medieval Warm Period in Earth’s climate change history. The presence of such a warm period, and the subsequent Little Ice Age that followed some centuries later, means that the theory that recent upward trends in global temperature have an anthropogenic basis is inaccurate, and possible invalid.

Which certainly doesn’t do any favours to Al Gore et. al.
