Since the U.S. began recording weather in 1851, two Atlantic hurricanes of such intensity have never hit our country in the same season, until now.
It started with Harvey, the tropical storm that transformed in a matter of 48 hours into one of the strongest hurricanes to hit the United States in over a decade. Harvey was followed by Irma, which also began its rampage as a tropical storm that quickly grew into a Category 5 hurricane.
Both Harvey and Irma made landfall as Category 4 hurricanes, wreaking havoc in southern Texas, parts of Louisiana, the U.S. Virgin Islands, Bahamas, Florida, southern Georgia and Alabama, with flooding continuing up to the Carolinas.
Many have suggested that these storms, along with August’s solar eclipse, are signs of “the end of times.” But before we break out our black clothes and prepare for Judgment Day, let’s consider another possibility for the “noise of the sea and its crashing waves:” climate change.
No, I am not saying the storms were caused by our refusal to give up our paper diaries and fossil fuels, but it could have contributed to the power of them. When people burn fossil fuels to create energy or drive cars, carbon dioxide is released into the atmosphere. This carbon dioxide traps heat in our atmosphere, which many scientists will attest has contributed to global warming.
There is a way to cycle the carbon dioxide out of our atmosphere. The solution comes from trees. Trees take in carbon dioxide and release it back as oxygen. However, because of our love for wood and paper products, trees are becoming less prominent around the world. The World Resources Institute reports we have lost 80 percent of Earth’s natural forests. We cut down anywhere from 3.5 billion to 7 billion trees every year.
With more fossil fuels being burned and less trees to absorb all of that CO2, there is more heat being trapped in our atmosphere. The Earth’s average temperature has risen about 0.7 degrees Celsius in the last century, “roughly ten times faster than the rate of ice-age-recovery warming,” according to NASA's Earth Observatory. This heat is causing water molecules to expand and ice caps to melt, resulting in rising sea levels across the globe.
To put this into perspective, according to a 2011 U.S. Geological Survey report, Louisiana is losing 16.6 square miles of land a year, or about a football field of land every hour.
So here we are, with warming ozones and rising sea levels. What role do these factors play in the devastating hurricanes our country has faced this season? An article by National Geographic phrases it quite well: “Many weather experts say we are already seeing the effects of higher ocean temperatures in the form of stronger and more frequent tropical storms and hurricanes/cyclones. Warmer surface water dissipates more readily into vapor, making it easier for small ocean storms to escalate into larger, more powerful systems."
Scientists have already begun studying the hurricanes we have seen, and are waiting to make official statements on the correlation between climate change and these particular storms.
Climate change is a very real, very serious problem our world is facing. Yet, many continue to deny its existence, or at least avoid acknowledging human involvement in the matter.
President Trump has even denounced the effects we as humans have on climate change, going so far as to withdraw the United States from the Paris Climate Agreement, a pact to reduce global greenhouse gas emissions.
Dr. Suzana Camargo, a professor of ocean and climate physics at Columbia University, wrote the following in a statement to The Weather Channel: “Listen to the climate scientists that actually work with climate change, the evidence is there. Don't listen to what your friend's opinion on Facebook [is], or what the politicians think, or the scientists of other fields, who only have ‘opinions’ are not working on the topic. Climate change is real and will affect all of us.”
