The earth is roughly 4.65 billion years old, possessing therefore a vast history in which climate change occurs naturally and ceaselessly. For example, millions of years ago, long before human beings existed, much less industrialised, huge naturally - driven temperature swings — significantly larger than the 1.5 degree Fahrenheit rise of the past 150 years — caused the onset and, in time, the cessation of ice ages.
We recognise that the best opportunity for human life to flourish during such periods is provided by electric power, indoor heat, thermal clothing, advances in medical science, air conditioning, sun screen, and the like — all products of applied science, technology, and industrialisation. Whether or not human industrial activity contributed to the slight warming of the past 150 years, two truths are certain: This mild warming, despite decades of alarmism, poses no immediate catastrophic threat to human life — and government's restricting of the economic activity required to attain flourishing life across all climates, is the exact opposite of a proper course of action.
The human environment is kept clean and safe primarily by advances in science, technology, and industrialisation. For example: development of steel and concrete enables construction of reservoirs, water mains, indoor plumbing, and sewer mains that keep sewage out of the drinking water; advanced technology enables men to drain swamps that are breeding grounds for malaria - carrying mosquitoes; heating and central air conditioning permit human beings to live comfortably in extreme climate conditions, without breathing smoke from indoor fires; and so forth.
Eliminating all subsidies to both fossil fuel companies and "alternative" or "green/renewable" energy companies, and a definitive end to government incentives/penalties for energy producers will encourage free thinking entrepreneurs to develop and cultivate earth's resources in service of human life.
