The signs of global warming are all around us. Heightened summer temperatures, prolonged and dangerous forest fire seasons, catastrophic storms and floods like those brought by hurricane Katrina, and unprecedented droughts around the world. As the temperatures rise, so do the greenhouse gas emissions that are pumped into the atmosphere daily by industry, governments, and individuals driving their oversized and unneeded SUVs.
But even as the evidence of global warming and the impending potential environmental catastrophe continues to grow, people are often reluctant to admit to themselves or others that the effects of global warming are a phenomena that must be dealt with. These photos show dramatic evidence that something is causing the earth to warm at an accelerated rate

The top photo shows ice in the Artic Circle in 1979, while the second shows ice in the same region in 2003. Both images are composites generated by measuring the total amount of ice present during a given year.
According to a NASA website "the loss of Arctic sea ice may be caused by changing atmospheric pressure patterns over the Arctic that move sea ice around, and by warming Arctic temperatures that result from the buildup of greenhouse gases in the atmosphere."
One way to help reduce global warming, and thereby slow the artic ice melt, is to learn more and do more about energy conservation and energy efficiency. Even if melting glaciers and the disappearing habitat of the polar bear is not your primary concern, energy conservation makes sense, because it saves you money. |
