Permafrost, or permanently frozen ground - soil, sediment or rock that remains at or below 0° Celsius for at least two continuous years - makes up about 24 percent of the exposed land mass in the Northern Hemisphere: that’s approximately 22.79 million square kilometers. Permafrost can be thousands of years old, or it can be just beginning. Either way, as permafrost thaws, it jeopardizes both man-made structures and natural features. Thawing permafrost on mountain slopes can lead to landslides.

And it’s melting.

Besides posing threats to structures and landscapes on a local scale, melting permafrost emits carbon dioxide and methane, according to the Commonwealth Scientific and Industrial Research Organisation (CSIRO), making permafrost a threat on a global scale.

June 29, 2009 - For the first time, the World Trade Organization (WTO) teamed up with the United Nations Environmental Programme (UNEP) to release a report outlining the relationship between trade and climate change. The report describes the multitude of ways in which climate change and trade intersect.

Using current scientific knowledge as well as current literature and a survey of national policies, the two organizations worked together to create a report that summarizes concerns regarding existing and projected climate change, impacts of climate change, and on possible responses, through adaptation and mitigation, to the challenges posed by climate change.

The report states that climate change is “unequivocal.” The evidence, gathered through a review of thousands of scientific publications, is compelling, and describes that human activities are “very likely” the cause of such global warming.

The biggest concern that the report denotes is that; barring major changes in policy, law, action, and attitude, global greenhouse gas emissions are expected to increase over the coming decades, with emissions increasing anywhere from 25 to 90 percent by 2030. It is also anticipated that a greater proportion of greenhouse gases will be emitted from developing countries.

It’s in the papers and on TV. It spreads across the Internet (including this very post), and it is finding its way into the classroom. Global climate change is nothing new. And it certainly isn’t going away. Not yet, anyway.

A report, “Global Climate Change Impacts in the United States,” was put out on June 16, 2009. The report compiles years of scientific research and takes into account new data not available during the preparation of previous assessments. It was produced by a consortium of experts from 13 U.S. government science agencies and from several major universities and research institutes.

The American Academy of Environmental Medicine (AAEM) has recently reported a link between genetically modified (GM) foods and adverse health effects. The AAEM is advising precaution because GM foods have not been properly tested for human consumption and because there is significant evidence of probable harm. Therefore they advise:

Physicians to educate their patients, the medical community, and the public to avoid GM foods when possible and provide educational materials concerning GM foods and health risks.

Physicians to consider the possible role of GM foods in the disease processes of the patients they treat and to document any changes in patient health when changing from GM food to non-GM food.

Our members, the medical community, and the independent scientific community to gather case studies potentially related to GM food consumption and health effects, begin epidemiological research to investigate the role of GM foods on human health, and conduct safe methods of determining the effect of GM foods on human health.

For a moratorium on GM food, implementation of immediate long term independent safety testing, and labeling of GM foods, which is necessary for the health and safety of consumers.

But why should GM producers like Monsanto be concerned with this? One Monsanto official told the New York Times that the corporation should not have to take responsibility for the safety of its food products.

Despite any confusion that you might be facing, the facts on global warming are not up for debate.

It is true that there are some natural causes of global warming. However, there is no doubt amongst the world’s leading experts that the current dangerous warming trend is primarily caused by humans.

To understand how humans cause global warming, it is important that you are aware of the link between your daily activities and the greenhouse effect. Furthermore, once you understand this, it is easy to see that you have the power to help stop global warming from getting worse.

The primary way humans cause global warming is by burning fossil fuels. This increases the amount of carbon in the atmosphere, which leads to an increase in the Greenhouse Effect.

Leading experts at the 2009 Aspen Environment Forum called ocean acidification caused by high levels of CO2 emissions a “planet changer”, and predicted that all coral in the ocean would be in danger of dying off by mid-century if we continued to burn fossil fuel at our current rate.

Ken Caldeira of Carnegie Institution, Martin Hoffert of New York University, and Dawn Martin of SeaWeb told attendees at the session “The Ocean Carbon Cycle: Facing the Damage” that we haven’t taken the issue seriously enough, and expressed dismay at the lack of media coverage for such an important issue.

“People would be more upset if you told them that their favorite TV show was canceled than if you told them that entire biomes would disappear.” - Ken Caldeira, Carnegie Institution

Barack Obama was sworn in as the 44^th President of the United States of America today. As one of the first moves of his presidency, he has suspended all of former-President George Bush’s midnight regulations. The order was issued by White House Chief of Staff Rahm Emanuel directly following the swearing in of Obama.

The regulations will not go into effect until Obama has had a chance to review their legality. Hopefully, this will undo some of the damage Bush attempted to leave our country with, such as his permitting coal companies to dump waste near rivers and oil companies to drill without reviewing the endangered species act.

Water contamination by toxic chemicals appears to be the cause of a mutation which resulted in the deaths of thousands of bass larvae in Australia. The two headed fish survived a mere 48 hours before dying off en masse.

Dr. Matt Landos of the Australian College of Veterinarian Sciences specializes in aquatic animals, and says that this is the first time he has ever seen anything like this. He sees no natural explanation for the deaths and is pinning the likely cause on the chemicals being used by a local macadamia nut plantation.

After completing its annual wolf population estimate, Yellowstone National Park has announced that the number of wolves inside the park has declined by 27% since the end of 2007. 124 wolves are now thought to reside in the park, down from 171. Is this a normal fluctuation? Read the rest of this entry »
