Earth’s climate is complex and constantly changing
Earth’s climate is an enormously complex system with thousands of variables in constant flux. Natural cycles of warming and cooling have existed as long as earth has had a climate. We only began to make large-scale measurements in the last 100 years, so this system is poorly understood.
Attempts to manipulate climate are limited by the complexity and inertia of the system. Dr. James Hansen of NASA, the father of the global warming theory, estimates the Kyoto protocol would only affect temperatures by .13°C by 2100, and it would take 30 Kyotos to have an “acceptable” impact on climate change. “Should a catastrophic scenario prove correct”, states Dr. Richard Lindzen, an MIT climate expert, “Kyoto will not prevent it.”
No single indicator can provide proof of a global change. The thinning of the Greenland ice sheet may be due to human causes, natural variations in snowfall, changes in ocean currents, a long-term warming of the planet since the transition from the last glacial period, continued warming since the end of the Little Ice Age following the Medieval Warm Period, or all of the above.
Politicians and the media are eager to embrace the latest crisis
Climate changes during the twentieth century were often accompanied by widespread panic, only to be quickly forgotten when dire predictions failed to materialize. Intellectuals, the media, and political institutions find it profitable to capitalize on emergencies which focus public attention on the issues they champion. Often their predictions go far beyond the most alarmist of scientific bodies. Science writer David Appell, who has written for such publications as the New Scientist and Scientific American believes that global warming will “threaten fundamental food and water sources. It would lead to displacement of billions of people and huge waves of refugees, spawn terrorism and topple governments, spread disease across the globe.” It would be “would be chaos by any measure, far greater even than the sum total of chaos of the global wars of the 20th century.” This doomsday scenario hardly follows from the hesitant estimates of a 1.1 to 6.4°C temperature rise and 18 to 59 cm sea level rise by 2100 predicted in 2007 by the IPCC.
Attempts to halt climate change are not only costly and futile, but ignore the benefits of a warmer climate
Adapting to a warmer climate has many costs, but many benefits as well. According to NASA satellite data, higher levels of CO2 have dramatically increased biomass production and biodiversity worldwide. Global warming may cause Africa to become more arid, but enormous territories in Siberia and Canada might finally be open to settlement, and new resources and shipping routes will become available.
The focus of environmental movements is usually on reversing anthropogenic causes of ecological change. Such attempts are not only futile, but ignore the large scale economic destruction caused by environmental restrictions on human productivity. Free societies and technological innovation have allowed human ingenuity bring about vast improvements in human life. This change has almost doubled the life expectancy and quadrupled the standard of living in the developed world – and is now transforming the developing world. Disrupting the global economy would have a snowball effect on future living standards, as well as retard future technologies will help us adapt to a constantly changing world.
A genuine cost-benefit analysis should weight the costs of wealth destruction and long term inhibition of technological progress against the highly uncertain costs of adjusting to environmental changes. Human beings have never passively resigned themselves to environmental changes, but adapted their society to make optimal use of their environment.
Wealth, technology, and human ingenuity are our most powerful tools for dealing with change
Even the most alarmist of scientists generally agree that there is little humanity can do to influence the global climate for many decades, even if we wrecked an industrial civilization that has allowed billions of people to leave immeasurably longer and better lives. Our resources would be far better spent creating innovative technology that allows us to make the best of a constantly changing climate than crippling industrial civilization (our best tool for dealing with a constantly changing world) in a futile attempt to stop climate change.
