Donald Trump tweeted about how global warming must “come back fast” because of the colder temperatures in the Midwest. By cold, I mean it’s -20 degrees with the windchill making the temperature feel like -50 degrees. Exposed skin can experience frost bite in minutes with hypothermia to follow. It’s dangerous leaving my apartment right now, which means I need to take necessary precaution in how I dress. Trump’s response shows how little our population knows the science behind global warming and I wanted to address this in a non-judgmental post. Global warming is happening even though temperatures are rapidly dropping in other areas.
The National Aeronautics and Space Administration (NASA) defines global warming as warming effects caused by heat being trapped in Earth’s atmosphere instead of moving towards space. Normally, heat would escape into space, but instead certain chemicals cause heat to be trapped on Earth causing temperatures to rise. This is known as the “greenhouse effect.” Carbon Dioxide, Methane and Nitrous Oxide contribute to the “greenhouse” effect. These chemicals are released by burning fossil fuels, producing waste and using fertilizer.
At first, one may think who cares? Why does it matter that temperatures are rising on Earth? Let’s discuss the rising sea level. Rising sea level caused by glaciers melting into the water could potentially sink low sea level cities such as New Orleans or even Miami could be underwater within decades. Besides sea levels, certain areas on Earth can become dry making it more difficult to grow essential crops. Over time, less crops means less overall food supply. Global Warming should scare you, as it does me. Our Earth could be negatively impacted permanently if we don’t change our current path.
Going back to the beginning, why do temperatures get colder if Global Warming is occurring? Towards the North Pole is the Polar Vortex. The Polar Vortex consists of strong winds when spinning create high and low pressure systems which help give us the weather we have. However, when temperatures rise, the winds will start to meander instead of being isolated in the North Pole which means here in Minnesota, temperatures are way below 0 degrees.
This post isn’t meant to cause a debate because Global Warming is occurring. I’m here to provide education on what may be a confusing phenomenon. Reading Trump’s tweets further reminds me how our science education is lacking. Our Earth is going through a crisis and we need to do something before it’s too late.
