To help transform our understanding of the biosphere, ecologists — like climate scientists — should simulate whole ecosystems, argue Drew Purves and colleagues.

As Gujarat readies itself to hold an event to showcase its business-friendly environment, there is some good news for the state. A report released today shows it replaced Tamil Nadu in terms of freest state in 2011.

The report, co-published by the Cato Institute, Academic Foundation, Indicus Analytics and the Friedrich Naumann Foundation, says on a scale of 0 to 1 points, Gujarat scored 0.64 points, followed by Tamil Nadu at 0.56. Tamil Nadu was the freest state in 2009.

A leading environmental group working for conservation of flora and fauna has sought intervention of the External Affairs Ministry to put pressure on Pakistan to ban hunting of rare birds, Houbara bustards, which has drastically reduced India's share of their annual winter migration and affected the desert eco-system.

The hunting of Houbara bustards, taxonomically classified as Clamydotis undulata , through falconry in Pakistan has led to an alarming decline in their numbers. The poaching mainly in Sindh province along the international border is not only a cause of serious concern for India but also in violation of wildlife protection laws and international conventions.

London: Rise in sea levels in the future due to the melting of the Greenland and Antarctic ice sheets could be substantially larger than IPCC estimates, according to a new first-of-its-kind study. Researchers from the University of Bristol found that the future rise in sea levels predicted by the Fourth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) may be even greater.

The ice sheets covering Antarctica and Greenland contain about 99.5% of Earth’s glacial ice which would raise global sea level by some 63m if they were to melt completely.

Teeth-chattering cold winds from Siberia to intensify; farmers worried, but wheat crop safe

Icy Siberian winds have chilled northern India and will intensify in the days ahead, making the winter even more severe, and highlighting the uncanny rise in extreme weather patterns such as droughts, hot spells and torrential downpours like the one that swamped Mumbai in 2005. For companies selling beverages, winterwear and heaters, business is booming with sales rising up to 40% in one of the coldest Indian winters in decades, but farmers are getting anxious about the impact on vegetables, pulses and oilseeds although the wheat crop is secure. The weather office says there is no quick relief in the offing.

The world must go back to harnessing the powers of the sun as it was done at the beginning of human civilisation to deal with global environmental changes, Taiwanese Nobel laureate Yuan Tseh Lee said on Sunday.

“We must return to sunshine to develop a more harmonious role with nature,” he said. “Once in history we were the children of the sun and were dependent on it for our needs, but we shifted to fossil fuels. We must dissociate ourselves from them and turn back to the sun to deal with global environmental change,” Lee said at the centenary session of the Indian Science Congress here.
