(The Daily Climate )

Coverage of climate change issues jumped in 2013, fueled by reporting on energy issues – fracking, pipelines, oilsands – and a heavy dose of wacky weather worldwide.

The climb, 30 percent above 2012 levels, marks the end of a three-year slide in climate change coverage and is the first increase in worldwide reporting on the topic since 2009, based on analysis of The Daily Climate's aggregation database.
