From a frigid winter to an oppressively hot summer, 2013 has had its share of extreme weather. The widest tornado ever recorded in the United States wreaked havoc on Oklahoma. Wildfires ran rampant in the West, claiming the lives of 19 young firefighters in Ariz. The world as a whole experienced one of the hottest Junes ever recorded.

This infographic from the World Resources Institute plots the most extreme weather events from January until now. WRI created a similar infographic last year, focusing on weather events from January 2012 through September 2012. According to their site, the group focuses on the intersection between environment and socio-economic development, topics that come to the forefront in the aftermath of weather-related disasters.

"All weather events are affected by a warming planet," President Obama said in his climate change speech on June 25th. "The question now is whether we will have the courage to act before it's too late."
