‘Spate of hot years proves global warming man-made’

A record-breaking string of hot years since 2000 is a sign of man-made global warming, says a new study, and there is a decreasing chance it was caused by random, natural swings.

Last year was the hottest since records began in the 19th century.

All scientists blame the trend on greenhouse gases from burning of fossil fuels, stoking heat waves, droughts, downpours and rising sea levels.
