The increasing frequency of downpours in our region is just part of what scientists call “the new normal” under climate change. In Maryland, data released earlier this year by the National Oceanic and Atmospheric Administration show that the frequency of rains greater than 4 inches has increased since 1950, as have the number of days warmer than 100 degrees F and the number of nights over 70 degrees F.

Seasonal patterns of precipitation have also changed, with more rain typically falling in spring and fall and less rainfall in the summer. Winters are warmer and shorter and spring comes earlier.

These new weather patterns are products of four big climatic changes that began in the mid-1800s: The air is warmer, the ocean is warmer, there is more water vapor in the air, and sea levels are rising.
