The past year has brought prolonged droughts to the Greater Horn of Africa and parts of Europe and Asia, Australia and Brazil. There were also a record number of devastating hurricanes in the Atlantic Ocean.

Temperatures are getting hotter, and they are getting hotter faster now than at any time in the past.
