Researchers have estimated that the number of snow storms has doubled in the past two decades, and with global warming they are expected to increase and be stronger
Snowstorms, just like what the US faced this weekend, have doubled in number over the last 20 years. From 1960 to 1994 the United States suffered nine snowstorm in the year. Since 1995, this average increased to 19.
And not just the frequency is increasing. More snowstorm are forming outside normal storm season from October to March, according to the findings of scientists.
In the past two decades, there have been more than three snowstorm in the year from April to September compared with the period 1960 to 1994. This is according to research scientist Jill Coleman from Ball State University in Indiana.
A snow storm classified as hurricane has winds of 35 meters per hour and visibility of 400 meters away. These conditions must be constant for at least three hours.
According to USA Today, a reason for the dramatic increase could be better reporting and monitoring of storms. But there may be other explanations.
According to Coleman, the sunspot cycle may have fault, where snowstorms are increasing over time, while sunspot activity is waning. This activity occurs in the 11th annual cycles and is currently at its lowest point.
Sunspots are dark regions on the sun caused by interactions with the Sun’s magnetic fields.
Scientists do not fully understand them, but can generate large explosions on the solar surface, releasing radiation to the earth.
“Periods with minimal sunspots tend to coincide with frequent polar outbreaks in the Northern Hemisphere that may increase the likelihood of snow storms,” said Coleman.
“However, sunspot activity is only a small component in explaining the frequency of snow storms.”
Another reason for the increased number of storms could be climate change caused by man.
Michael Mann, director of the Earth Science System in Pennsylvania thinks there is research that suggests that climate change is making snow storms more frequent and more intense.
“There are studies supported by other researchers suggest that climate change will bring more strong snowstorm in the Northeast for the same reason that the storm happened in the US. This cause are unusual warm temperatures on the surface of the Atlantic Ocean.
When mixed with a large humidity of the cold blast from the Arctic, something that will keep global warming, create large amounts of energy and moisture and numerous snow falling, as what we saw in the US.
At least 37 deaths were attributed snow storm that swept America last week, clearing snow from the inhalation of carbon monoxide and car crashes.
People are the causes of record temperatures?
Storms are the only thing that is growing as a result of climate change caused by man, say scientists. Since the beginning of the new millennium, the world has experienced a record warm years.
Scientists say it is very possible that these global temperatures, unprecedented in advance to be caused by emissions of gases of human activity such as burning fossil fuels like coal and oil.
This comes just days after NASA confirmed that 2015 was the warmest in history, with temperatures increased by 1 degree Celsius above those before industrialization.
The most recent study by the Potsdam Institute for Climate Impact Research in Germany claims it is “very unlikely” that 13 of the 15 hottest years recorded in the last 150 years have occurred since 2000.
According to them, there are 600 to 130,000 times more likely that changes occur due to the nature than from human activities and their influence on climate change.
