Biden’s aim is to reduce global warming, not change the climate (Letters) – masslive.com
The Cal Thomas column which appeared Dec. 31, “Biden’s climate change litmus test,” is plain wrong. Thomas alleges Biden and his team will try to “change climate”. In fact, they are trying to keep climate from changing. Climate change is caused by global warming which in turn is caused by the greenhouse effect. The Biden administration plans to reduce global warming which will restrain climate change. It will not change the climate.
The heat we are trapping can heat the surface of the Earth enough to reach tipping points. What are tipping points? Generally, they are points at which the Earth turns off its cooling mechanisms and adds heating mechanisms. For example, the Antarctic Ice Sheet covers 5.4 million square miles, enough to cover the contiguous United States and Mexico. Imagine how much of the sun’s heat energy is repelled by these reflective surfaces. As they melt more and more of the sun’s heat energy is absorbed and will raise the temperature of the Earth’s surface regardless of further global carbon emissions. While it is true the Earth has been warming slowly and evenly of its own accord for many thousands of years, extensive scientific studies prove that over the last hundred years, fossil fuel emissions are causing a sudden unnatural spike.
We have the technology and engineering and industrial capacity to change this scenario and in fact are doing so. Twenty-five gigawatts of wind power are being developed off the shore of Massachusetts alone. Solar farms and roof top photovoltaics proliferate. Electric cars and trucks are usurping the place of internal combustion vehicles. Charging stations, heat pumps, modern electricity transmission and a renewed power grid will need construction and installation. All this development will mean more investment and more labor. One hopes an expansive capitalism with a fair return on investment and a comfortable healthy standard of living for labor will result. These are the changes we should expect the new administration, John Kerry and all, to facilitate and lead.
