Extreme Weather        Originally scheduled for Jan. 9th now Feb. 27th

 

Extreme weather events are becoming more numerous. 2016 has become a record year, with numerous droughts, heat waves, forest fires, but also record floods, and blizzards. How can you have more floods and snow and yet still have record heat, fires and drought? Aren’t the two mutually exclusive? No. In fact most extreme weather events are due to Climate Change. Global Warming is not only making everything Warmer, it is making the weather Weirder. That is why Global Warming is now referred to as Climate Change. Perhaps Global Weirding would be appropriate.  extreme-weather

Climate Change is the average of weather patterns over time. When the average increases in temperature, the extreme weather events increase in number and severity.  https://www.epa.gov/climate-change-science/understanding-link-between-climate-change-and-extreme-weather

The Arctic is having unprecedented heat waves with temperatures reaching 50 degrees above normal. This results in record loss of sea ice which in turn heats up the north more because more solar energy is absorbed instead of being reflected off the ice. http://www.independent.co.uk/news/science/north-pole-50-degrees-warmer-hotter-normal-thursday-christmas-weather-temperature-arctic-a7488291.html

This destabilizes the polar vortex, which is a band of cold air that normally rotates around the arctic circle. Without the sea ice and with the above average heat, the polar vortex destabilizes, becomes wavy, and can dip way down to Florida causing Storms and freezing weather much further South than normal. https://www.washingtonpost.com/news/capital-weather-gang/wp/2016/10/31/polar-vortex-shifting-due-to-climate-change-extending-winter-study-finds/?utm_term=.516bd2320abd

A warmer atmosphere can carry more moisture which results in more snow and rain storms, and a warmer ocean gives rise to more powerful hurricanes and typhoons. “A warmer climate spurs the evaporation of water from land and sea and allows the atmosphere to hold more moisture—thus setting the stage for more extreme precipitation…Extreme precipitation is likely when a storm passes through a warmer atmosphere holding more water. In warmer months, it takes the form of torrential rainstorms; in winter, blizzards are more likely.” http://www.climatehotmap.org/global-warming-effects/rain-and-snow.html

The result of glaciers melting means that the sea level is rising. This means that when storm surges happen at high tides, coastal flooding can occur. https://ncar.ucar.edu/press/evaluating-the-effects-of-future-sea-level-rise-and-storm-surges-along-us-coastlines
