A new report by the outreach and research organization Climate Central reveals which U.S. states are warming the fastest, with Rhode Island taking the top spot over the past 100 years.

For each state in the continental U.S., scientists from Climate Central calculated averages of the daily high and low temperatures from National Climatic Data Center’s U.S. Historical Climatology Network of weather stations. Then, they determined how much the average daily temperatures changed each decade over the past 100 years.
