When extreme weather strikes, somebody, somewhere always asks about a link to climate change. It's time we gave straight answers.

A claim that global warming caused the 2010 Russian heatwave could bring closer the day when climate victims can sue oil firms.

Climate change scenarios suggest an increase in tropical ocean temperature by 1–3°C by 2099, potentially killing many coral reefs. But Arabian/Persian Gulf corals already exist in this future thermal environment predicted for most tropical reefs and survived severe bleaching in 2010, one of the hottest years on record. Exposure to 33–35°C was on average twice as long as in non-bleaching years. Gulf corals bleached after exposure to temperatures above 34°C for a total of 8 weeks of which 3 weeks were above 35°C.

Heat stress is an important aspect in the lives of people working under exposed conditions for long hours. It is interesting to examine the impact of global warming on the occurrence of heat stress in India. This study uses India Meteorological Department (IMD) daily temperature gridded data to
investigate the changes in frequency and episodes of extreme temperature events in seven temperature homogenous regions and the country as a whole by applying the guidelines suggested by the World Meteorological Organization ‘Expert Team on Climate Change Detection and Indices’. It is
