Sun on climate change: I didn’t do it!

New scientific data shows that the sun is unlikely to have contributed much to the global warming phenomenons like melting ice caps, higher temperatures, more unstable, and, according to some, Miley Cyrus.

“Research examining the causes of climate change in the northern hemisphere over the past 1000 years has shown that until the year 1800, the key driver of periodic changes in climate was volcanic eruptions. These tend to prevent sunlight reaching the Earth, causing cool, drier weather. Since 1900, greenhouse gases have been the primary cause of climate change,” scientists from University of Edinburgh said in a recent press release.

Climate scientists speak out in favour of nuclear energy

Some of the world’s most prominent scientists have written an open letter calling for the development of nuclear energy.

James Hansen, Ken Caldeira, Kerry Emanuel and Tom Wigley wrote:

“As climate and energy scientists concerned with global climate change, we are writing to urge you to advocate the development and deployment of safer nuclear energy systems. We appreciate your organization’s concern about global warming, and your advocacy of renewable energy. But continued opposition to nuclear power threatens humanity’s ability to avoid dangerous climate change.”

In an email interview with rediff.com, Hansen further explained:

“We should compare alternatives for the future. The air pollution from fossil fuels kills far more people than the worst nuclear technology of the past, the most weakly regulated nuclear technology,” he said.

Now for someone who for a long time has been a supporter of nuclear energy, this makes a lot of sense. However, it’s going to have a lot of people up in arms….luckily the arms won’t be nuclear….

Climate change seems to send North Pole on mini walk-about

Melting ice due to rising temperatures seem to have sent the geographic North Pole on a slow trek.

Scientists from University of Austin, Texas, have recently reported that the melting ice masses around the North Pole have caused it to shift at least a couple of centimetres every year since 2005.

It might not sound of much, but the movement is more than three times the year-on-year movement registered between 1982 and 2005.

Retreating glaciers threaten Peru’s water supply

A new study in the Journal of Glaciology spells bad news for regions of Peru. The study shows that the glaciers on the Cordillera Blanca mountain range are retreating much faster than previously thought.

This is likely to lead to droughts in many of the arid regions that get their water from the glaciers and a water shortage that will take effect about 20 – 30 years earlier than had previously been expected.

Michel Baraer, lead researcher on the study, said that the results showed that the time needed for the region to adapt to the coming water shortages, previously thought to be decades off, simply didn’t exist.
