A Quote by James Hansen

Recent warming coincides with rapid growth of human-made greenhouse gases. The observed rapid warming gives urgency to discussions about how to slow greenhouse gas emissions.

'Scientific' computer simulations predict global warming based on increased greenhouse gas emissions over time. However, without water's contribution taken into account they omit the largest greenhouse gas from their equations. How can such egregious calculation errors be so blatantly ignored? This is why man-made global warming is 'junk' science.

Michael Myers

Are global temperatures rising? Surely, they were rising from the late 1970s to 1998, but 'there has been no net global warming since 1998.' Indeed, the more recent numbers show that there is now evidence of significant cooling [...] Mankind is responsible for just a fraction of one percent of the effect from greenhouse gases, and greenhouse gases are not responsible for most of what causes warming (e.g., the Sun).

John R. Lott Jr.

We need to remind ourselves that our ultimate goal is not to reduce greenhouse gases or global warming per se but to improve the quality of life and the environment. We all want to leave the planet in decent shape for our kids. Radically reducing greenhouse gas emissions is not necessarily the best way to achieve that.

Thomas P.M. Barnett

There is a natural greenhouse effect that contributes to warming. Greenhouse gases trap heat and thus warm the Earth because they prevent a significant portion of infrared radiation from escaping into space.

George W. Bush

...there is no substantive basis for predictions of sizeable global warming due to observed increases in minor greenhouse gases such as carbon dioxide, methane and chlorofluorocarbons.

Richard Lindzen

Warming of the climate system is unequivocal...most of the global average warming over the past 50 years is very likely due to anthropogenic greenhouse gases increases.

Rajendra K. Pachauri

There is no significant man-made global warming at this time, there has been none in the past and there is no reason to fear any in the future. Efforts to prove the theory that carbon dioxide is a significant 'greenhouse' gas and pollutant causing significant warming or weather effects have failed. There has been no warming over 18 years.

John Coleman

On Earth Day I made a commitment to reduce our emissions of greenhouse gases to 1990 levels by the year 2000. And I asked for a blueprint on how to achieve this goal. In concert with all other nations, we simply must halt global warming. It is a threat to our health, to our ecology, and to our economy. I know that the precise magnitude and patterns of climate change cannot be fully predicted. But global warming clearly is a growing, long-term threat with profound consequences. And make no mistake about it, it will take decades to reverse.

William J. Clinton

When ships reduce their speed they use less fuel, resulting in fewer greenhouse gas emissions and other pollutants; the global shipping industry accounts for nearly 3 percent of global greenhouse gas emissions.

Tatiana Schlossberg

India was a late comer to industrialization, and as such, we have contributed very little to the accumulation of greenhouse gas emissions that cause global warming. But we are determined to be part of the solution to the problem.

Manmohan Singh

The basic scientific conclusions on climate change are very robust and for good reason. The greenhouse effect is simple science: greenhouse gases trap heat, and humans are emitting ever more greenhouse gases.

Nicholas Stern

There are many who still do not believe that global warming is a problem at all. And it's no wonder: because they are the targets of a massive and well-organized campaign of disinformation lavishly funded by polluters who are determined to prevent any action to reduce the greenhouse gas emissions that cause global warming out of a fear that their profits might be affected if they had to stop dumping so much pollution into the atmosphere.

Al Gore

Global warming results not from the emission of greenhouse gases into the atmosphere, but from an unusually high level of solar radiation and a lengthy - almost throughout the last century - growth in its intensity.

Khabibullo Abdusamatov

Climate change is the world's greatest environmental challenge. It is now plain that the emission of greenhouse gases, associated with industrialization and economic growth...is causing global warming at a rate that is unsustainable.

Tony Blair

... The reality is that atmospheric CO2 has a minimal impact on greenhouse gases and world temperature. Water vapor is responsible for 95 percent of the greenhouse effect. CO2 contributes just 3.6 percent, with human activity responsible for only 3.2 percent of that. That is why some studies claim CO2 levels are largely irrelevant to global warming.

Walter Cunningham

Greenhouse gas emissions and global warming are among humanity's most pressing concerns. Societal expectations on climate change are real, and our industry is expected to take a leadership role.
