Satellite laser images reveal extensive thinning of polar ice

According to a new study by scientists at British Antarctic Survey (BAS) and Bristol University, an extensive thinning of polar ice has been revealed in Antarctica and Greenland, by the images captured by a laser aboard an orbiting NASA spacecraft.

The study, published Wednesday in the journal Nature, specified that the satellite laser is essentially used by the scientists with the BAS to measure infinitesimal changes in the thickness of glaciers and ice sheets, along the coast of the Amundsen Sea in West Antarctica.

Britons become more sceptics about climate change

Public skepticism about climate change is on the rise as today less Britons trust scientists who say that climate change is the outcome of human activities.

As per survey conducted by researchers at Cardiff University twice as many people now believe that evidence on climate change have been exaggerated as compared with the figures from survey conducted five years ago.

40 per cent of the people surveyed believe that leading experts are still debating the causes of climate change.

Britain could face blackout by 2016 due to shortage of green projects

Professor David MacKay, government's new energy adviser said that Britain will have to suffer blackouts by 2016 unless more green energy projects are not developed. Britain has plans to phase out coal power plants in 2016 and green energy is not coming on stream fast enough due to lack of public support.

Speaking on the topic, Professor David MacKay said shortage of energy would force the country to turn to natural gas, which is not the long-term direction the country wants to be heading in.

Royal Society warns against risky geo-engineering technologies

A research made by the Royal Society warned that unproven techniques such as CO2 removal and giant space mirrors are risky.

The study examined two types of geo-engineering technologies. One is to reflect the sun rays away from Earth with the help of giant space mirrors to manage solar radiations and the second is to remove carbon dioxide from the air.

Speaking on the issue, John Shepherd, a professor at Southampton University, said, "We are not advocating geo-engineering. It is not an alternative to emissions reductions."
