With colleagues at the University of Reading, we performed a simple analysis to assess what factors played a role in this record heat, specifically the roles of greenhouse gas emissions associated with global warming, the natural climate oscillation known as El Niño, as well as solar activity and volcanic aerosols.
A team of international scientists says that it is virtually certain that the heatwave that stretched across much of Europe in early July was more likely to happen now than in the past due to climate change.
2014 looks increasingly likely to be the warmest year ever recorded in Europe, according to a new analysis of European temperature records dating back to the 1500s. What role did global warming play?
