A Quote by Raymond Pierrehumbert
The big damages come if the climate sensitivity to greenhouse gases turns out to be high causing greater global warming than current projections. Then it's not a bullet headed at us, but a thermonuclear warhead.

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.
The basic science is very well established; it is well understood that global warming is due to greenhouse gases. What is uncertain is projections about specifics in the next few decades, by how much will the climate change.
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.
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).
The climate's sensitivity to greenhouse gases is considerably lower than the Intergovernmental Panel on Climate Change claims - so much lower, in fact, that the warming we would expect from doubling the amount of carbon dioxide in the atmosphere would be quite modest and offer very little risk.
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.
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.
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. It is no secret that when they go up, temperatures in the world's oceans trigger the emission of large amounts of carbon dioxide into the atmosphere. So the common view that man's industrial activity is a deciding factor in global warming has emerged from a misinterpretation of cause and effect relations.
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.
Global warming causing climate change may be the ultimate issue that unites us all.
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.
The global warming hysterics don't just offer opinions and beliefs about greenhouse gases and the like. These are people who speak as if they belong to a cult.
I've been vegan for 15 years, and it turns out it makes a very big impact on the environment to eat fewer animal products, which cause more greenhouse gases than all of transportation combined.
...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.
The different policies reduce damages by only a modest amount. Indeed, one of the surprises is how little the policies affect the damages from global warming. The reasons are that, because there is so much inertia in the climate system and because the Protocol reduced the global temperature increase by only a fraction of a degree over the next century.
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.
