Chair of the Nobel Peace Prize-winning Intergovernmental Panel on Climate Change (IPCC), Rajendra Pachauri speaks about both the geophysical effects of climate change as well as the human dimension: the social, economic and equity considerations that need to be made to prepare for the changes ahead.

Despite California legislation to address global warming, greenhouse gas emissions continue to increase. Four degree annual temperature rise is what we may expect. Randy Hayes, Rainforest Action Network founder, has been described in the Wall Street Journal as “an environmental pit bull.” He works from Washington DC at Foundation Earth, a new organization rethinking a human order that works within the planet’s life support systems.

Climate change denier Lord Monckton's statements are challenged by data and reports.  This series of videos, from the science journalist known on YouTube as Potholer54 and are a great resource for anyone.

Here is another of this series here on EarthSayers.

Monckton's Stance on Climate Change is bunkum that is to say nonsense.

"Yes, there is a greenhouse effect. Yes, CO2 contributes to it. Yes, it causes warming. Yes, we emit CO2. Yes, warming will result. But not a lot."

What does environmental devastation actually look like? At TEDxVictoria, photographer Garth Lenz shares shocking photos of the Alberta Tar Sands mining project -- and the beautiful (and vital) ecosystems under threat.

For almost twenty years, Garth's photography of threatened wilderness regions, devastation, and the impacts on indigenous peoples, has appeared in the world's leading publications. His recent images from the boreal region of Canada have helped lead to significant victories and large new protected areas in the Northwest Territories, Quebec, and Ontario. Garth's major touring exhibit on the Tar Sands premiered on Los Angeles in 2011 and recently appeared in New York. Garth is a Fellow of the International League Of Conservation Photographers

http://www.ted.com Days before this talk, journalist Naomi Klein was on a boat in the Gulf of Mexico, looking at the catastrophic results of BP's risky pursuit of oil. Our societies have become addicted to extreme risk in finding new energy, new financial instruments and more ... and too often, we're left to clean up a mess afterward. Klein's question: What's the backup plan? Click on the book image to order from Amazon.

An interesting and popular presentation of the argument for why being a climate change denier is risky business based on scientific data supporting global warming.

A brief recap of the satellite news media tour on February 1, 2012 that looked at the science of falling snow, how NASA observes snow from space, and the factors that lead to the 2010 "Snowmageddon." For more on the story, check out http://www.nasa.gov/topics/earth/features/know-snow.html
