In something of an irony, in May 2016, Donald Trump, who has labeled climate change a "con job," a "hoax" and "bull ---t," applied to build a wall along a luxury golf course that he owns in Ireland that is threatened by rising seas caused by climate change.
The Republican Party Platform reads, in part, “Climate change… is the triumph of extremism over common sense… We support the development of all forms of energy… including coal, oil, natural gas, nuclear power, and hydroelectric… we support [fracking].” The platform’s support for renewable energy would be limited to private capital. Later, the platform reads, “The United Nations’ Intergovernmental Panel on Climate Change [IPCC} is a political mechanism, not an unbiased scientific institution… We reject the agendas of both the Kyoto Protocol and the Paris Agreement… We demand an immediate halt to U.S. funding for the U.N.’s Framework Convention on Climate Change…”
And we put these people in control of our government, to the ultimate detriment of the children, grandchildren, and great-grandchildren of my generation.
Earth’s climate achieved a balance shortly after the last ice age. How this happened is not rocket science. It’s basic chemistry, biology, and geology.
For eons, microscopic sea creatures busily absorbed Carbon Dioxide (CO2) from the ocean when creating their tiny shells of calcium carbonate (CaCO3), which settled to the ocean bottom, were compressed, and became limestone. Meanwhile, termites in tropical regions were busily creating CO2. Volcanoes were occasionally spewing CO2, Sulfur Dioxide (SO2), Hydrogen Sulfide (H2S) and particulates into the atmosphere. Subduction of tectonic plates (slowly, to be sure) was sliding limestone on the ocean floor under continental plates where some was eventually spewed back into the atmosphere from volcanoes as CO2. The orogenies that built mountains (also slowly) occasionally exposed limestone to erosion, returning some CO2 to the air. Trees absorb CO2 from the air, die, rot, and return that CO2 to the air, unless they are buried for millennia and turn into peat and coal.
There are many natural sources of CO2. There are many natural sinks for CO2 and Earth had achieved something of a balance before we (humankind) began burning, in a century-and-a-half, fossil fuels that had been laid down (thereby capturing carbon) for millennia.
We have measured the amount of CO2 in the air, and have seen it increase steadily. We have measured this directly on top of a mountain in Hawaii since about 1958. There has been a steady rise from less than 320 parts per million to over 400 parts per million.
We have measurements from Antarctic and Greenland ice cores of CO2 in the atmosphere going back to at least 425,000 B.C.E.
We know the CO2 that comes from burning fossil fuels (coal, oil, natural gas/methane) is demonstrably different from CO2 from current, natural sources. The simplest way to determine this is to look at the amount of Carbon 14 in the CO2. “Younger” CO2 has a large amount of Carbon 14. Carbon 14 has a half-life of 5,700 years, and does not exist in fossil fuels that are millions of years old… such as coal, laid down during the Carboniferous Period (c. 359—299 million years B.C.E.)
The correlation between rising atmospheric CO2 and rising temperatures has been measured and plotted since about 425,000 B.C.E. It’s a fact.
Earth is warming. That too, is a fact.
What is the source of the heat? The sun, only the sun, and nothing but the sun. And that will be the topic of the next post.

I have been a student of weather and climate ever since I became a private pilot and realized that my ability to predict weather was a life-and-death matter on cross-country flights. I have read and studied many references since before “global warming” and “climate change” became issues.
