Trump Administration Releases Report on Climate Change

A new report on climate change released by the U.S. Government shows not only that climate change is very real but it is also going to have dire effects on our economy.

The report, which was released on Friday, was due in December but was released early as Americans were distracted by family, friends, shopping, and good food.

The report states that if the United States was unable to change its course, the economy could lose over 10% of its GDP in a worst-case scenario.

This report only comes days after a tweet from the President asking what happened to global warming after most Americans across the nation experienced record-breaking cold weather.

However, as explained in most reports, a “record-breaking weather event” like the one on Thanksgiving is nothing compared to the yearly average, which shows humans are dealing with warming conditions.

As of right now, the top countries in the world, better known as the G20, are not reaching climate targets, according to research done by Climate Transparency.

Without any serious prevention or attempts to reduce our greenhouse emissions, the average global temperatures will rise over 9 degrees Fahrenheit by the end of the 21st century.

We know that rising temperatures can have negative effects on our farming production and our health. We will be unable to work some days due to temperatures being too high, which will result in deaths to the lack of food and water.

We have been taught this many times in science class, and it is up to us to make sure that our children have a planet to live on by 2100.

What If We Only Used Wind Energy?

It has become common knowledge of the lack of sustainability in humanity’s current answers to meeting energy needs. Eventually, we as a species will run out of those resources upon which we rely. For this reason, scientists have been looking for renewable resources that work, and would provide the world with a cleaner, more sustainable alternative to fossil fuels. Among these ideas, wind power has done very well for us in certain areas. However, on its own, even a resource as plentiful as wind may not help us.

A study done by Harvard University applied physicists, Lee Miller and David Keith, found that if the United States was able to produce 0.46 terawatts of electric power (the amount currently used) using just wind turbines, that area would be much warmer than normal.

Miller and Keith were able to do this study using a parallel world between the years of 2012-2014. They made the central United States as location of the 0.46 terawatt wind farm.  They found that the center of where the huge wind farm would be, the temperatures would rise as much as 1 degree Celsius or about 2 or 3  degrees Fahrenheit give or take. The temperature in the United States would rise 0.24 degrees which is would about a 1 degree Fahrenheit increase. The 0.24 figure is figure of our current rise temperatures. By 2030, the United States’ average temperature would have risen 0.24 degree Celsius.

Wind turbines peek above the low clouds, providing clean, renewable energy and a path forward… but even they can’t be the only way to a sustainable tomorrow.

To put into perspective how wind turbines could affect something as drastic as the weather, turbines alter the climate by increasing the atmospheric mixing that is within the boundary layer–the layer of our atmosphere just above the Earth’s surface. Numerous turbines would pull the warmer air from the boundary layer’s upper part down towards the cooler air.

The turbines would also redistribute moisture and heat. According to another recent study featured in Science News, it was found that a wind farm with the amount of terawatts required by the United States could result in more precipitation and vegetation in the Sahara Desert itself.

In the end, the temperature rise with the wind farm would be spontaneous, but it would still take a century to even see a reduction in greenhouse gas emissions to even counteract the rise in heat from the turbines.

While this study scenario is very unlikely, getting rid of fossil fuels altogether would need a mixture of wind, solar, and geothermal energy sources (and maybe even nuclear), and as we all know, a reduction in fossil fuels would reduce carbon-dioxide emissions.

While having a single massive wind farm may answer the call for better renewable energy sources, it is ofttimes worth taking a step back to see if something new could be even more disastrous than the status quo. While wind energy may not be a singular savior, it nonetheless will continue to help in humanity’s way towards a greener tomorrow.
