Worse Things Increasing in the Air Than CO2
When we think of greenhouse gases we immediately think of CO2 emissions. But there are others on the list that are far worse and growing at a greater rate. CO2 just stands out because it is the most prevalent and can last in the atmosphere for 100 years or more.
On the Hinkle Charitable Foundation website for the environment there are some pretty interesting facts about global warming presented in a series of reports. Burning fossil fuels for energy is the main source of atmospheric greenhouse gases. We pretty much know that. The third report explained a measurement called the Global Warming Potential (GWP) that includes both a gas’s ability to trap solar heat and how long the gas persists in the atmosphere. I learned there are a lot worse gases than CO2 that are man made like perfluoromethane, an etchant and cleaning agent. It’s presence in the atmosphere is increasing at a much faster rate than CO2. Not good.
Mother Nature certainly isn’t putting cleaning agents into the atmosphere, or sulfurhexafluoride, another dangerous greenhouse gas used in the electric industry as a dialectric medium for high voltage circuit breakers and other electrical equipment. We produce 8000 tons of this stuff to use every year.
Now get these numbers. If CO2 has a one hundred year GWP of one, and stays in the atmosphere one hundred years, how bad is perfluoromethane with a GWP of five thousand seven hundred, and lasts over fifty thousand years. And sulfurhexafluoride is outright evil with a GWP of twenty two thousand two hundred and stays in the atmosphere three thousand two hundred years.
As usual these gases are measured in parts per thousand. Again our lives are measured in parts per thousand. How many ppts have accumulated in the atmosphere over the years? This stuff never goes away. We’re messing with more than a few generations here.
