Erie is getting warmer...

Erie is ranked among the fastest-warming cities in the nation according to climate central. In recent decades, temperatures have increased between 1.6 and 4.06 degrees. As higher temperatures reduce winter ice coverage on the Great Lakes, more moisture is available to feed lake-effect snowstorms like the one that dumped more than 156 inches of snow on Erie from December 2017 through February 2018.

Impacts of Rising Temperatures

  • Increased pests like mosquitos and ticks

  • More frequent late-winter warm-ups that can cause early budding in trees which are then at risk from frost 
  • Changes in where species are occurring and the timing of their migrations
