Shifting Mild Weather Patterns

A global analysis on mild weather by NOAA and Princeton University shows a dramatic shift in the number of mild climate days across the world.  Mild climate weather are temperatures between 64 and 86 degrees F, indicative of low humidity, and less than half inch of rain and dew points below 68 degrees F (Science Daily).  While most research is done on big weather changes like hurricanes, droughts, blizzards, floods, etc. little is done to look at the affects of mild weather change.  This study is extremely valuable and offers insight that will help economically as these mild weather patterns affect travel, tourism, construction, transportation, agriculture, and much more.

The tropics are set to lose milder days down the road by 10-13% by the year 2100 due to climate warming and human-caused greenhouse gases in the atmosphere.  The scientist predict that tropical regions, including Africa, Asia, and Latin American, will experience the largest decrease in mild weather because of this rising heat and humidity.  These changes bring about economic damages and public heath issues.

On the contrary, areas along the mid-latitude such as U.S., Canada, and Northern Europe will see an increase in mild weather days. These areas are projected to gain up to 10-15 days a year of mild weather by the end of the 21st century. The interesting factor is that mild weather may drop during hot and humid summers and rise in the fall season.

How did these projections get made? “Scientists used high-resolution climate models to investigate the changing patterns of mild weather globally by examining the effect over time of increased warming from the buildup of greenhouse gas emissions in the atmosphere.” (Science Daily). Coupled with decades of data gathered by different organizations scientists were able to make these predictions. Taking a look at all different forms of weather change is important in preparation for the future and to help find solutions to mitigate the impacts.
