Experts say nuclear power needed to slow warming

PITTSBURGH (AP) — Some of the world's top climate scientists say wind and solar energy won't be enough to head off extreme global warming, and they're asking environmentalists to support the development of safer nuclear power as one way to cut fossil fuel pollution.

Four scientists who have played a key role in alerting the public to the dangers of climate change sent letters Sunday to leading environmental groups and politicians around the world. The letter, an advance copy of which was given to The Associated Press, urges a crucial discussion on the role of nuclear power in fighting climate change.

Environmentalists agree that global warming is a threat to ecosystems and humans, but many oppose nuclear power and believe that new forms of renewable energy will be able to power the world within the next few decades.

That isn't realistic, the letter said.

"Those energy sources cannot scale up fast enough" to deliver the amount of cheap and reliable power the world needs, and "with the planet warming and carbon dioxide emissions rising faster than ever, we cannot afford to turn away from any technology" that has the potential to reduce greenhouse gases.

The vast majority of climate scientists say they're now virtually certain that pollution from fossil fuels has increased global temperatures over the last 60 years. They say emissions need to be sharply reduced to prevent more extreme damage in the future.

In 2011 worldwide carbon dioxide emissions jumped 3 percent, because of a large increase by China, the No. 1 carbon polluting country. The U.S. is No. 2 in carbon emissions.

The scientists acknowledge that there are risks to using nuclear power, but say those are far smaller than the risk posed by extreme climate change.

"We understand that today's nuclear plants are far from perfect."

خلاصه خبر:

به عقیده برخی از مهمترین دانشمندان آب و هوا شناس دنیا، انرژی باد و خورشید برای مقابله با روند فزاینده گرمایش جهانی کافی نیست و حکومت ها باید از توسعه انرژی هسته ای ایمن تر به عنوان راه حل اصلی کاهش مصرف سوخت های فسیلی حمایت کنند.

در سال 2011 تولید دی اکسید کربن در جهان به واسطه رشد صنعتی چین 3 درصد افزایش یافت. چین هم اکنون بزرگترین تولید کننده گازهای گلخانه ای جهان است. آمریکا در مکان دوم قرار دارد.

گرچه انرژی هسته ای مخاطرات بزرگی برای محیط زیست دارد (همچون خطر انفجار هسته ای و آلودگی رادیواکتیو یا مشکلات ناشی از دفع پسماندهای خطرناک)، اما روند گرمایش جهانی چنان تهدید بزرگی برای آینده کل بشریت است که نمی توان از این انرژی صرف نظر کرد. انرژی های تجدیدپذیر مانند انرژی خورشیدی و باد توان تامین نیاز رو به رشد انسان به انرژی را ندارند و این مهم تنها از دست انرژی هسته ای ساخته است.
