Alternative energy sources like wind offer a way to lessen a country’s carbon footprint. But global warming trends could soon change the way the wind blows.

As rapid arctic warming shrinks the heat gap between the North Pole and equator, Northern Hemisphere winds could lose some oomph — up to 40 percent over the next century, depending on region.

This week marks 25 years since more than 1,700 scientists, led by the Union of Concerned Scientists, issued a “warning to humanity” concerning the costs of continued environmental destruction.

Now, they’ve issued another — this one signed by 15,000 scientists representing 184 countries.
