Earth’s climate changes frequently, sometimes beneficially, sometimes disastrously (as during repeated glacial periods and the Little Ice Age of 1350-1850), as a result of shifting and interacting solar, cosmic, oceanic, atmospheric and other forces that we are only beginning to understand. While some continue to insist that human “greenhouse gas” emissions are causing potentially catastrophic changes in climate and weather, growing numbers of scientists say nature, not man, rules the climate and causes changes of varying extent and significance every few decades, centuries and millennia.
Humans, plants and wildlife have survived and even prospered during past climate changes – and will continue to do so. Indeed, our technology and wealth will make people and civilizations much better able to prepare for and adapt to most climate changes, although another Pleistocene-scale ice age would devastate northern cities, decimate agricultural production, and drive human and species migrations.
Computer models are helpful for improving our understanding of how weather and climate systems work and change over time. However, because they are based on poor data and false, questionable or simplistic premises, they are useless in forecasting future climate and weather. Moreover, actual temperature and weather data demonstrate that alarmist warnings of dangerous global warming are not supported by reality. Regulating carbon dioxide may be profitable for certain industries and governments, but will impose enormous costs on society – while having no effect on our weather and climate.
Today, the real danger is laws and policies implemented in a misplaced belief that humans can control or prevent climate change. These policies raise energy costs, kill jobs, impose especially heavy burdens on poor families, and make it hard for still impoverished nations to develop, provide affordable energy, create jobs, and improve lives and living standards. Moreover, even drastic reductions in U.S. carbon dioxide emissions will mean nothing globally, because China, India and other developing nations are now emitting far more CO2 than the United States could eliminate even by shutting down its economy.
