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.

I recently wrote a post concerning a report on climate change issued by the U.S. Government stating that “climate change has immediate and local impacts – it literally affects people in their backyards.” Well, as it turns out, there’s more to the story.

With the recent introduction of H.R. 2454 - the American Clean Energy and Security Act of 2009 - there has been an increased push for climate change awareness. The purpose of the bill is to create clean energy jobs, achieve energy independence, reduce global warming pollution and transition to a clean energy economy.

This all sounds great, right? Well, not to everyone seems to agree. Not everyone believes in climate change. With such a debate raging, it may be difficult to see through the haze of words and opinions that is filling the air.

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.

Just about any long-term West Oakland resident can rattle off a list of health issues effecting their community: toxins from cargo ships docking at the nearby Port of Oakland, diesel smoke from Port-bound trucks, pollution from the two freeways that border the neighborhood, illegal dumping, and lack of accessible health care.

One of the biggest issues facing us right now is global warming. Its effects on animals and on agriculture are indeed frightening, and the effects on the human population are even scarier. The facts about global warming are often debated, but unfortunately, even if we disagree about the causes, global warming effects are real, global, and measurable. The causes are mainly from us, the human race, and the effects on us will be severe. Read the rest of this entry »

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.

Full page ads questioning President Obama’s stance on climate change were published in the Washington Post, the New York Times, the Chicago Tribune, the Washington Times, and the Los Angeles Times last week, paid for by the Cato Institute.

Environmentalists, journalists, and scientists alike are calling foul and poking holes in the assertion that “there has been no net global warming for over a decade now.” Read the rest of this entry »

Americans eat lots of meat. So much so that livestock is now one of the leading contributors to global warming, responsible for 18 percent of greenhouse gas emissions as measured in a carbon dioxide equivalent.

A recent United Nations report concluded that the meat industry causes almost 40% more greenhouse gas emissions than all the world’s transportation systems — that means all of the globe’s cars, trucks, planes and ships combined.

Kathy Preston poses an important question for meat-eating Americans concerned about the effects of global warming: what are the effects of going vegetarian for just one day? Here are her astounding statistics about how going vegetarian for a single day can help prevent global warming:
