Greenhouse gases surge to new highs

10 warmest years all occurred since 1998, with the top four after 2014

TAMPA, Florida - Planet-warming greenhouse gases surged to new highs as abnormally hot temperatures swept the globe and ice melted at record levels in the Arctic last year due to climate change, a new report said on Wednesday.

The annual State of the Climate Report, compiled by more than 450 scientists from nearly 60 countries, describes worsening climate conditions worldwide in 2017, the same year that US President Donald Trump pulled out of the landmark Paris climate deal.
