New Research published in the Journal of Climate sheds new light on the long-standing question of how much of the observed changes in Earth’s temperature are due to natural ocean cycles. The short answer is, very little.
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.
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?
