Since 2010, Maine has broken five daytime record high temperatures for every record low temperature, according to a new Associated Press data analysis of temperature trends across the United States. The study shows that record high temperatures are on the rise in all regions across the country, though in some regions, such as the Northeast, the trend is more pronounced. “What the study shows is what we would expect in a warming climate,” said Maine State Climatologist Sean Birkel, who works as a research assistant professor at the University of Maine Climate Change Institute.
