Global warming and what it means for weather in the u.s

While the earth is increasingly getting warmer people who oppose global warming usually use the current weather to argue that isn't happening because there is still snow or it is cold outside. While global warming is more about the average temperature of the earth getting warmer it doesn't really get rid of snow or cold days. On the topic of snow in the United States, global warming could also cause worse snow storms and worse heat waves than ever before as hotter temperatures cause high highs and low lows in the polar jet stream meaning that hot days will be hotter and might last longer and cold days could be colder and last longer too. The polar jet stream being disrupted could have really have adverse effects on the lives of people as hotter days and colder storms could endanger lives and this could also disrupt agriculture and really damage the U.S economy.

"The polar vortex was notably unstable during several recent winter seasons, which in turn influenced the jet stream. For example, during the 2011/2012 winter, there was a shift in the position of the jet stream. Typically New England, the Great Lakes, and parts of the Great Plains sit north of the jet stream and remain cold in the winter season. However, the 2011/2012 position of the jet stream meant these regions were south of it for most of the winter, which helped produce the fourth warmest US winter on record. The lack of snowfall and snowpack for the winter of 2011/2012 and the following spring was a precursor to the large drought episode that impacted two-thirds of the nation during the following summer and autumn."
