A Quote by James Hansen

...99 percent confident that the world really was getting warmer and that there was a high degree of probability that it was due to human-made greenhouse gases.

... 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

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

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.

James Hansen

Concentration of greenhouse gases, especially CO2, have increased substantially since the beginning of the industrial revolution. And the National Academy of Sciences indicates that the increase is due in large part to human activity.

George W. Bush

Emissions of greenhouse gases warm the planet, altering the carbon and water cycles. A warmer ocean stores more heat, providing more fuel for hurricanes. A warmer atmosphere holds more water, bringing dangerous deluges. Rising sea levels threaten coastal zones.

Johan Rockstrom

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.

13. 99 percent is a very large percentage. For instance, easily 99 percent of people want a roof over their heads, food on their tables, and the occasional slice of cake for dessert. Surely an arrangement can be made with that niggling 1 percent who disagree.

Daniel Handler

...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

The percent likelihood of a society becoming physically violent if it is physically affectionate towards its infants and tolerant of premarital sexual behavior is 2 percent. The probability of this relationship occurring by chance is 125,000 to one. I am not aware of any other developmental variable that has such a high degree of predictive validity.

James W. Prescott

A lot of what is done by the climate lobby is anti-science. But there is some science behind it. Like, there are greenhouse gases, and they do contribute to warming. But if you look at the last, say, 160 years, the first 80 of that period, they went up about four-tenths of a degree. And now, the second 80 that CO2 has increased by, what, 30 percent or something, it's gone up five-tenths of a degree. And there's been in the last 30 or 40 years, there's been no real increase in storms or bad weather.

Charles Koch

In reality, serendipity accounts for one percent of the blessings we receive in life, work and love. The other 99 percent is due to our efforts.

Peter McWilliams

I came out wanting to be an actor. From my first view of the world, that's what I wanted to be. I'm made of 99 percent ham and 1 percent water. I was just cooked that way!

Mike Myers

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

Take one round-trip flight between New York and California, and you've generated about 20 percent of the greenhouse gases that your car emits over an entire year.

Tatiana Schlossberg

Getting knocked out in your underwear in the Octagon is pretty embarrassing, but people are like, 'The guy he's fighting is really, really good, and he is a UFC fighter, so he can still beat up 99 percent of the world,' so it's not that embarrassing.
