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.

    The American people aren’t stupid enough to buy the manmade climate crisis narrative

    The American people are increasingly not buying into the global warming (er, climate change) scary scenarios, but the Green Left, led by Al Gore, is responding by turning up the heat — and increasingly seeking to silence opposition they cannot control. That this is a losing technique escapes notice because they believe that nobody cares enough about stopping them to resist and overcome the firings, threats of prison time, and even worse from the shrill sirens of statism.

    New Congress must rein in runaway EPA

    With the President and the unaccountable regulatory agencies joined by the Supreme Court in declaring Congress to be irrelevant in governing America, it is time for Congress to raise itself up from the dead and reestablish itself as the sole creator of new laws. Given that too many in Congress have gone along with this massive Presidential (and regulatory) power grab, this may require sweeping out a lot of dead wood from both chambers.

Climate Science

    The climate alarm industry is scientifically bankrupt

    Increasingly, pub lic policy is becoming the captive of a new scientific-technological elite that produces fatally flawed research that seeks not the truth but rather to sculpt data that fit their theory of the world. Indeed, many scientific journals have been publishing bogus studies which reference nonexistent data. A primary reason is that most climate research funding comes from public alarm-dependent agenda-driven government sponsors and their Green activist acolytes.


    Financing Climate Crisis, Inc.

    CFACT Senior Policy Advisor Paul Driessen outlines six stratgegies through which the Obama Administration is using climate change to “fundamentally transform” America. THey are attacking dissenters, trying to censor skeptical speech, and worse.


    The climate con goes on

    CFACT Senior Policy Analyst Paul Driessen says that the media are too heavily invested in the global warming scam to ever admit that they had been played by politicians and “scientists” for decades. There is a growing body of evidence that President Obama’s and the UN’s claims that carbon dioxide emissions are killing the planet are merely a smokescreen for their real , and now clearly stated, intention — to destroy capitalism and take the wealth of America and the West.


    Record keepers cooked global temperature books

    We are learning that quite possibly the entire “global warming” movement is based on the falsification of actual temperature records by scientists who have systematically replaced real temperatures with computer-generated temperatures that more closely fit their grossly flawed climate models. This level of deceit — which has been rewarded with billions upon billions of dollars by politicians and nonprofit billionaires alike — means that the entire history of “climate change” is about as reliable as predicting the winners of horse races a month down the road.


    What if Obama’s climate change policies are based on pHraud?

    The demand for scary scenarios to prop up failing global warming arguments has apparently led two scientists at the Pacific Marine Environmental Laboratory (PMEL), which is part of the National Oceanic and Atmospheric Administration (NOAA), to ignore 80 years of 20th Century ocean pH data as measured with glass electrode pH (GEPH) meters that include over 2 million records of ocean pH levels. These data do not line up with the PMEL team’s computer modeling, a strong indicator that the model, for which its creator Dr. Richard Feely, has won a $100,000 Heinz Family Foundation award, is likely worthless scientifically (though clearly of great value politically). Just as with the Michael Mann hockey stick scam, this Feely scam needs to be exposed and discredited as junk science and its arrogant perpetrators forced to accept true peer review.


    New paper faults World Health Organization’s willful exaggeration

    A new briefing paper by Dr. Indur Goklany examines the World Health Organization’s recent report on climate change and finds that its estimates of future mortality from global warming are grossly exaggerated. “Because of its willful exaggerations,” says Goklany, “the WHO study risks scaring people into taking ill-considered costly actions to limit greenhouse gases rather than focusing on higher priority global health issues such as hunger, malaria, and diarrhoeal diseases, which can be addressed at a fraction of the cost.”


    EPA hides science behind draconian regs

    The EPA has virtually rewritten the Clean Air Act to suit its own ends, and while a divided Congress refuses to act to rein in the agency, the Supreme Court had a shot and even admitted that the agency had overstepped its boundaries, but still let the EPA embark on a mad race to destroy the nation’s foundational energy sources — coal, oil, and natural gas. Even worse, new EPA regulations, which will cost the U.S. economy nearly $3 trillion and innumerable job losses, are backed by
    “secret science” that the EPA will not even share with Congress.
