Marine Biologist, Dr. Stephen Palumbi, discusses the oceans and global warming which is transforming our environment. The temperature, acidity and water level of the ocean is rising. These changes are increasing in speed and magnitude and their effects will last for centuries. Corals are among those organisms hit hardest by global warming. The rate our climate changes will determine whether coral can survive or not. Uploaded on Nov 5, 2008
Features Amed Jkoghlaf, Executive Secretary of the Convention on Biological Diversity. He defines biodiversity. The loss or degradation of biodiversity, now occurring at an unprecedented pace at local and global levels is a threat to our environment, economies, cultures and societies. It is changing our conception of ourselves and our place in the world. Human impact on biodiversity, ecosystems and climate continues to grow and the complexity and diversity of the range of services that flow from biodiversity are often unknown and undervalued.
People from all over the world express their concern over climate change and the future of our cities.

Jean-Pierre Quignard, professor in Ichtyology, tells us about the consequences of warming waters in the Mediteranean sea.
He says:'What solutions can we find to the modifications brought about by climate change in the Mediterranean? I am a researcher, I study fish and in this field, I see no solution.'
Speed of glaciers march to the sea is tripling!
On the Kangerdlugssuaq Glacier -- one of Greenland's largest ice fields -- scientists measure the movement of the ice sheet as it transports frozen water to the ocean. They discover that the speed of the glacier's march to the sea has tripled in just ten years. Alarm bells sound because at the current melt rate, within a few decades rising seas will have a profound effect on the low-lying countries of the world. January 20, 2012 uploaded. Gordon Hamilton is a glaciologist working on ice sheet dynamics, and the role ice sheets play in modulating global sea levels.
The Social Cost of Carbon estimates the monetary damages that result from carbon pollution -- essentially putting a value on the effects of climate change that are already costing us today. Webinar presentation (audio) by Maggie Fox.
The Obama Administration requires agencies to factor in these damages when making new policies. After careful scientific analysis, the current estimate was increased to $37 per metric ton of carbon pollution.
But Big Oil and Big Coal oppose this increase, attempting to reduce the social cost of carbon so that they can continue polluting recklessly.

This visualization shows how global temperatures have risen from 1880 through the end of 2013. NASA scientists say 2013 tied for the seventh warmest of any year since 1880, continuing a long-term trend of rising global temperatures. With the exception of 1998, the 10 warmest years in the 133-year record all have occurred since 2000, with 2010 and 2005 ranking as the hottest years on record.
The visualization shows a running five-year average global temperature, as compared to a baseline average global temperature from 1951-1980.
This color-coded map displays a progression of changing global surface temperatures anomalies from 1880 through 2013. Higher than normal temperatures are shown in red and lower then normal temperatures are shown in blue.

Energy producers, transporters and brokers of coal, specifically, Ambre Energy and Arch Coal Inc. have put Southwest Washington and the Pacific Northwest in the spotlight with proposals to transform ports into key shipping hubs in a worldwide realignment of valuable oil and coal resources. Under 14 different plans and operations, Washington and Oregon ports would essentially serve as a vast transfer station for the coal and oil being extracted from America's heartland, where raw materials are sent to domestic and overseas markets, primarily in Asia, demanding fuel and electricity for growth. This is a trailer for the documentary, Momenta which explores the impact of these plans and the citizen groups opposed to such plans.
All over the world, people are taking action to save the climate. All over the US, this Thanksgiving, people who have lived through climate disasters are giving thanks. Published on Nov 25, 2013

All over the US, this Thanksgiving 2013, people who have lived through climate disasters are giving thanks. And if we receive them they will stay with us forever.
