Medieval Warm Period — fact vs. fiction

The demonstrably false claim that the medieval warming period was warmer than today just won’t die because climate science critics never fail to come up with new recycled reasons as to why they think that it was.

This video looks at the scientific research to answer three basic questions: 1) Was the Medieval Warm Period global? 2) Was it warmer than today? 3) And what does this all mean anyway? I examine the internet feud over the hockey stick and the various myths and misinterpretations about the Medieval Warm Period that seem to be rife on the Internet. My sources for the myths are blogs and videos; my sources for the facts are scientific papers…

Is the Science of Global Warming Settled Enough for Policy?

The late Stephen Schneider delivers an engaging talk on the science of climate change and it’s implications for policy. Schneider was great at explaining what the science of climate change is and at helping the average person weed through the absurd media discussion of the topic.

Dr. Schneider is the Inaugural Visitor in the Zurich Financial Services Distinguished Visitors Program on Climate Change. He is the Melvin and Joan Lane Professor for Interdisciplinary Environmental Studies, Professor of Biological Sciences, and a Senior Fellow in the Woods Institute for the Environment at Stanford University. From 1973-1996 he served as a scientist at the National Center for Atmospheric Research, where he co-founded the Climate Project. His research focuses on climate-change science, integrated assessment of ecological and economic impacts of human-induced climate change, and identifying viable climate policies and technological solutions. He has consulted for federal agencies and White House staff in six administrations.

Himalayan Glaciers “no melt in 10 years”

The headlines recently announcing no melting of Himalayan glaciers for the past 10 years are, no surprise, not entirely accurate or telling the whole story. That’s what you get for learning your science from the popular press. The rest of the story is far more interesting. As usual, I look at the scientific paper all this hype is based on, and it comes up with something that hasn’t been so widely reported.

Monckton responds (part 1/2)

Amazingly famous climate change denialist Christopher Monckton responds to potholer54 pointing out by denying he said what he is on film saying.

Part 2

*corrected

Monckton has responded to my catelogue of his errors, on the website wattsupwiththat.com
It includes an extraordinary reversal of position on most of them, including an outright denial of what he said (needless to say, I have video tape of him saying it.)

This is a day old (that’s 3 years in interwebs time) but I couldn’t find it on tumblr to reblog so excuse my blindness if this is ancient.

“Earth Facing a Mini-Ice Age!!” say the media. Now for the science…
