I am not a climate scientist. I studied history, economics, and Latin in college. I dabbled a bit with political science and creative writing but never took a class even remotely related to climate science. Despite all that, I hold that the "climate crisis" is a hoax. Here are some interesting points:
1. When I was 10, the earth was heading toward an Ice Age. As a family, we would watch 'In Search of' hosted by Spock. I liked it because it had Spock. This episode provided a dark glimpse of what the world might be like in a single lifetime. If the scientists were wrong here, why are they right now?
2. 1816: The Year Without a Summer. In the wake of the 1815 eruption of Mount Tambora, so much debris was thrown into the atmosphere that the following year saw mass starvation from failing crops. New England had severe frosts every month of summer. Despite decades of pollution, humanity has been unable to duplicate the Year Without a Summer.
3. The Medieval Warm Period (950 to 1250) saw temperatures roughly equivalent to today. The Vikings found Greenland to be habitable and transplanted their agricultural and pastoral lifestyle there for several centuries. By 1400, the Greenland settlements were nearly gone and vanished soon thereafter because of the increasing cold. Clearly, this warming was not anthropogenic. Why is the current warming trend different from the Medieval Warm Period?
4. The Earth is currently in an ice age that began 2.6 million years ago. An ice age is geologically defined as the presence of extensive ice sheets in the northern and southern hemispheres. Because the ice sheets/glaciers have retreated for several millennia, the earth is experiencing an interglacial period. This 10,000 year warming is not anthropogenic. Why is the current - comparatively insignificant - warming different from that trend?
5. During the Mesozoic Era (252 million to 66 million years ago), the earth was 10 degrees Celsius warmer than it is today. There were no ice caps at the poles. This was not anthropogenic. Was 2016 hotter than an average year in the Mesozoic? If not, is it really the Hottest Year Ever?
The earth has been much warmer and much colder than today. The climate experienced these huge swings with no input from humans. These variations have developed over millions of years. Though these points may provide the layman some reason to doubt the ongoing panic about climate change, that isn't a reason to call it a hoax!
Like all living things, government wants to grow and prosper. Studies that 'prove' that climate change is anthropogenic provide cover for government to expand its power and reach. Taxes on pollution, regulations to make sure cars get more miles to the gallon, laws to make washing machines more energy efficient, and so on and so forth. There is so much that government can do, provided there is a basis for it. Thus, scientists who find that humanity is to blame and the problem could be solved by government intervention are handsomely funded. Scientists who conclude that it is the sun - which governments have no legislative authority to control - are not funded. Anthropogenic warming = funding. Natural climate cycles = no funding. Scientists are smart people and see the pattern.
