A new study concludes that the upward trend of global temperatures didn't slow this century, contrary to previous analyses that suggested the world is in the midst of a global warming hiatus.
Earlier observations showed that global surface temperatures increased by an average of 0.1 degree Celsius per decade from 1950-1999, a rise believed to stem from a surge in greenhouse gas emissions linked to human activity. But puzzlingly, for the period 1998-2014 the warming rate was recorded at a slower 0.06 degrees per decade even though greenhouse gas emissions continued to rise.
