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.



Our Climate Change Truth File Q&A contains answers to a broad range of questions about global warming science and policy.


CFACT Reports

Carbon Dioxide: The Gas of Life

Carbon Dioxide: The Gas of LifeIn this special report, “Carbon Dioxide: The Gas of Life,” CFACT senior policy advisor Paul Driessen examines carbon dioxide and its many benefits. While global warming alarmists rail against it, carbon dioxide is actually the “gas of life,” without which life on earth would perish.

Driessen explains in detail where carbon dioxide comes from, why it spurs plant growth, how it fights pollution, and its many other benefits. “Eliminate CO2, and plants would shrivel and die. So would lake and ocean algae or phytoplankton, grasses, kelp and other water plants. After that, animal and human life would disappear. Even reducing carbon dioxide levels too much – sending it back to pre-industrial levels, for example – would have terrible consequences for crops, other plants, animals and humans.”

“Carbon dioxide performs as many miracles for our planet as antibiotics and immunizations have for mankind. That is an amazing feat for a colorless, odorless, tasteless gas that represents just 0.04 percent of our atmosphere: the equivalent of just 40 cents out of $1,000 or 1.4 inches on a football field!”


A-Z Climate Reality Check

As the real world evidence mounts that global warming claims are failing, the climate activists have ramped up predictions of future climate change impacts to declare that it “worse than we thought.” Marc Morano, editor of CFACT’s Climate Depot, compiled a special report entitled “A-Z Climate Reality Check” that shatters any such illusions that the climate is “worse than we thought.”

The scientific reality is that on virtually every claim — from A-Z — the claims of the promoters of man-made climate fears are failing, and in many instances the claims are moving in the opposite direction. The global warming movement is suffering the scientific death of a thousand cuts. This Climate Depot special report categorizes and indexes the full range of climate developments in a handy A-Z reference guide. The A-Z report includes key facts, peer-reviewed studies and the latest data and developments with links for further reading, on an exhaustive range of man-made global warming claims.


The Science and Global Politics of Climate Change

Lord Christopher Monckton’s “The Science and Global Politics of Climate Change” is a 30 page special report written for heads of state and government, cabinet officials, and national legislators. It provides pragmatic, factual insight into climate science, economics and policy, and offers sensible, straightforward, affordable answers to the key questions now before the international community.

The world faces many real environmental problems. In any view, however, “global warming” is not one of them. Science shows that the world will not warm dangerously. Even if warming were to prove severe, focused adaptation to its consequences would be the most cost-effective approach.

Taxing or regulating carbon – however profitable it might be for the Armageddon industry and for cash-hungry governments – would make little measurable difference to the climate, and at a disproportionately extravagant cost – all pain, no gain.

    Global warming policies are bad for your health

    Do global warming policies save human lives? A Stunning new report found the exact opposite. The report, entitled “Global Warming Policies Might Be Bad for Your Health,” was produced by leading researcher Dr. Indur Goklany and found that issues of poverty like malnutrition and unsafe water have a global impact of death and disease 70 times larger than that of theoretical climate change.


    Carbon benefits trump costs by up to 500 to 1!

    EPA assumes zero benefits from the burning of fossil fuels while proclaiming heavy costs from increased carbon dioxide levels in the atmosphere. Now, as Greens push for increasing the alleged “social cost of carbon” from the current 36/ton (up from $22/ton back in 2010) to an astonishing $43/ton, Roger Bezdek and Paul Driessen show that EPA is violating federal law (including Executive Order 12866) by ignoring the massive benefits to society (some $70 trillion in the U.S. alone) from fossil fuels use.

    Green scientists debunk climate change myths

    Just as the Obama Administration, the EPA, the UN, and the compliant media are pumping up futuristic global warming horror stories, many of the world’s top scientists are speaking out ever more sharply against this fraud. Among them: Greenpeace co-founder Dr. Patrick Moore, German environmentalist Dr. Fritz Vahrenholt, Gaia promoter Dr. James Lovelock, and Nobel Laureate physicist Dr. Ivar Giaever. All the while, some of their former colleagues are now calling for the heads orf such skeptics on a silver platter.


    Global warming’s tree ring circus brings us the costliest show on Earth

Michael Mann invented the hockey stick to “prove” human-caused global warming, yet cherry-picked his tree rings and cheated on his data — as did Phil Jones and friends in East Anglia. Yet their sins may have been equaled by the phony hearings conducted at Penn State and in the United Kingdom that ignored nearly all of the evidence except that presented by the guys on the griddle. No wonder the world is laughing!

Yet Turney and his fellows can point fingers to their colleagues at the EPA and the UN’s IPCC as co-conspirators in their doomed adventures. We need to stand up and stop funding this nonsense before someone really gets hurt.
