Climate Central, a research and public outreach organization, examined historical climate data and identified the the U.S. states that are experiencing the greatest and the least amount of warming over the last 100 years. The state that has warmed the most over the last 100 years is Rhode Island. They also found three states have actually cooled over the last 100 years - Arkansas, Georgia and Alabama. It is interesting to examine their result as applied to regions. The northeast region has warmed the most, while the southeast has warmed the least.
But, there is an even more interesting result from their data. What they found is that they had to break it down to subsets of before 1970 and after 1970. Comparisons between these two data sets show the warming trend since 1970 has been three times as much as before 1970. In other words, the states were, mostly, warming before 1970. But, the warming rate is now three times as much as it was before 1970.
Keep that in mind next time someone tells you global warming has stopped.
