Ecosystems, Plants & Animals on the Move, but Fast Enough?
Dec/090
Some species are already on the move because of climate change, but a lot more is needed for species & ecosystems to survive.
A new study by the California Academy of Scientists attempts to estimate how fast species and ther ecosystems will have to move to keep up with climate change. On average, the team of scientists have concluded that ecosystems will have to shift at a rate of 0.42 kilometers (or about a quarter mile) per year.
There are differences across all the different ecosystems, of course. And there are human factors that will come into play as well.

45 Species of Galapagos Islands Extinct or Facing Extinction due to Overfishing and Climate Change
Dec/090
A new report published in the journal Global Change Biology shows that 45 species of the Galapagos Islands have become extinct or are facing extinction largely due to human activities.
The main causes are the 1982 El Nino and overfishing. The results show the great vulnerability of this diverse area to significant climate change and human activities.

Atlantic Ocean is Rising Faster than Previous 4,000 Years
Dec/090
An international team of scientists has determined that the Atlantic Ocean rose faster in the 20th century than at any time in the last 4,000 years, but not uniformly along the coast.
One of the researchers, assistant professor Benjamin Horton in the Department of Earth and Environmental Science at the University of Pennsylvania, says: “There is universal agreement that sea level will rise as a result of global warming but by how much, when and where it will have the most effect is unclear.” He and other researchers have now started to tackle this issue.
Interestingly, the rate of sea level rise in recent years varies according to how far north or south you are on the coast.

Fear’s Role in Climate Change Issues
Dec/090
Fear. It is a simple emotion. It is a feeling. But it can also create something complicated — in what it makes us think and do. Fear drives many decisions in the world, and may often cause us to make the wrong decision.
The important thing is realizing the difference between thoughtful awareness of negative ramifications and the actual feeling of fear.
On the following pages, I delve into the relationship between fear and the climate change decisions we are making everyday on individual and larger systematic levels. Additionally, I delve a little more into the issue of fear itself.
Greenland Ice Sheet Melting Faster than Ever
Nov/090
More data show that ‘Yes, climate change is happening, ice is melting at alarming rates, and the time for action is now.’
Independent research using state-of-the-art modeling and satellite observations shows that melting of the Greenland ice sheet is speeding up.
Four months ago, new research showed that Arctic sea ice was at its lowest point in about 800 years, another study a couple months ago showed suprisingly fast melting in Greenland and Antarctica. Now, research from other scientists in Bristol (UK) published in Science confirms that ice sheets in Greenland are melting at an unprecedented rate.
There has been a lot of effort in the past few months to knock down climate change activists, say it isn’t happening. No wonder, of course, given that we are quickly approaching one of the most important meetings in the history of the human race — the climate change conference in Copenhagen. This new report shows again that whether we admit it or not, ice is melting, sea levels are bound to rise, climate change is happening, and the whole world will be changed as a result of it.

Alaska Vows To Fight Polar Bear Protection With Lawsuits, Disses Climate Change
Oct/090
Now that the polar bear is about to receive over 128 million acres of critical habitat designation, the state of Alaska is taking legal action to challenge the decision.
Following the announcement that threatened polar bears are set to receive over 128 million acres of critical habitat designation, Alaska Governor Sean Parnell and Attorney General Dan Sullivan responded by taking legal action against federal protection of polar bears.

From Dikes to Natural Flood Plains: The Netherlands Changes Approach to Flood Control
Sep/090
The Dutch have been fighting rising seas longer than any nation in the western world. Much of the country lies below sea level, including the capital city of Amsterdam. Traditionally, dikes and concrete barriers have been used to hold back the sea, but now the Netherlands is changing course in its flood control efforts due to climate change. The Dutch are embracing natural flood plains for rivers and mangrove swamps in lieu of levees.
