A Quote by Graciela Chichilnisky

We are still learning how exactly the Earth reacts to increased CO2 and other greenhouse gases. We know it leads to warming seas which are melting the North and the South Poles, rising and starting to swallow entire coastal areas in the US and elsewhere, as the New York Times article documents.

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.

... 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

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

Rising sea levels will result in tens to hundreds of millions more people flooded each year with a warming of 3 or 4°C. There will be serious risks and increasing pressures for coastal protection in South East Asia (Bangladesh and Vietnam), small islands in the Caribbean and the Pacific, and large coastal cities, such as Tokyo, Shanghai, Hong Kong, Mumbai, Calcutta, Karachi, Buenos Aires, St. Petersburg, New York, Miami and London.

Nicholas Stern

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

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

I'm not a global warming believer. I'm not a global warming denier. I'm a global warming agnostic who believes instinctively that it can't be very good to pump lots of CO2 into the atmosphere but is equally convinced that those who presume to know exactly where that leads are talking through their hats.

Charles Krauthammer

There is universal consensus among experts that the earth's atmosphere is heating up - and that we are responsible for it by putting carbon dioxide in the atmosphere. We also know that the consequences of global warming are catastrophic. But how do we make sure that all countries reduce greenhouse gases?

Eric Maskin

We know that the warming rising seas will swallow entire island nations that are about 25 percent of the UN vote and perhaps at the end, even our civilization. This realization is traumatic and the first reaction to trauma is denial. Since there is some remaining scientific uncertainty, a natural response is to deny that change is occurring. This is natural but it is very dangerous.

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

Not a lot of attention has been paid to the Asian tiger mosquito, which is another species which we believe can also transmit Zika virus. It has a much broader range. It's found all the way north into coastal areas of Connecticut, Long Island and the New York metro area.

Laura Harrington

It's likely that CO2 has some warming effect, but real proof of that hypothesis is tricky. You have to confirm by observation exactly how the CO2 changes the situation at different altitudes in the atmosphere and in different regions of the world. For example, CO2 is supposed to warm the upper air faster than the surface, but the measurements don't show that happening. When the CO2 effect is eventually pinned down, it will probably turn out to be weaker and much less worrisome than predicted by the global warming theorists.

Nigel Calder

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

These proven positive consequences of elevated CO2 are infinitely more important than the unsubstantiated predictions of apocalypse that are hypothesized to result from global warming, which itself, may not be occurring from rising atmospheric CO2 levels. The aerial fertilization effect of atmospheric CO2 enrichment is the only aspect of global environmental change about which we can be certain; and to restrict CO2 emissions is to assuredly deny the biosphere the many benefits that accrue from this phenomenon.

Keith E. Idso

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

Even if we were to stop putting out greenhouse gases right now, we'd still face decades of warming.
