December was the coldest in 100 years in UK

Britain has just gone through its coldest December since nationwide records began 100 years ago, the Met Office said on Wednesday. The country shivered as temperatures averaged minus 1 degree Celsius, well below the long-term average of 4.2 degrees, and colder than the previous record for the month of 0.1 degrees hit in 1981. Provisional figures released by the forecaster showed that December saw exceptionally cold and snowy weather across the country, with temperatures regularly falling to between minus 10 and minus 20 overnight. The Arctic blast caused havoc with the country's transport sector, closing roads, airports and railways and hitting retail sales during the traditionally busy Christmas period as shoppers struggled to get to stores.

Scotland to get 100 pct green energy by 2025

"Scotland has unrivalled green energy resources and our new national target to generate 80 percent of electricity needs from renewables by 2020 will be exceeded by delivering current plans for wind, wave and tidal generation," Salmond said.

Diverse water sources key to food security

Increasingly erratic rainfall patterns related to climate change pose a major threat to food security and economic growth, water experts said on Monday, arguing for greater investment in water storage. In a report by the International Water Management Institute (IWMI), experts said Africa and Asia were likely to be hardest hit by unpredictable rainfall, and urged policymakers and farmers to try to find ways of diversifying sources of water. The IWMI research estimates that up to 499 million people in Africa and India could benefit from improved agricultural water management.
