Of course, who do we believe. An author from caranddriver.com who coincidentally says what George Jr - well proven liar - says? Or from those who come from where the work gets done. This from Ralph J. Cicerone, President, National Academy of Sciences on 21 Jul 2005 before the US Senate (and I recall Rush Limbaugh mocking this man back then):
Quote:
CURRENT STATE OF CLIMATE SCIENCE:
RECENT STUDIES FROM THE NATIONAL ACADEMIES
...
Nearly all climate scientists today believe that much of Earth’s current warming has been caused by increases in the amount of greenhouse gases in the atmosphere, mostly from the burning of fossil fuels. The degree of confidence in this conclusion is higher today than it was 10, or even 5 years ago, but uncertainties remain. As stated in the Academies 2001 report, “the changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability.” ...
Carbon dioxide can remain in the atmosphere for many decades and major parts of the climate system respond slowly to changes in greenhouse gas concentrations. The slow response of the climate system to increasing greenhouse gases also means that changes and impacts will continue during the twenty-first century and beyond, even if emissions were to be stabilized or reduced in the near future.
Simulations of future climate change project that, by 2100, global surface temperatures will be from 2.5 to 10.4 F (1.4 to 5.8C) above 1990 levels. Similar projections of temperature increases, based on rough calculations and nascent theory, were made in the Academies first report on climate change published in the late 1970s. Since then, significant advances in our knowledge of the climate system and our ability to model and observe it have yielded consistent estimates. Pinpointing the magnitude of future warming is hindered both by remaining gaps in understanding the science and by the fact that it is difficult to predict society’s future actions, particularly in the areas of population growth, economic growth, and energy use practices. ...
It is important to recognize however, that while future climate change and its impacts are inherently uncertain, they are far from unknown. The combined effects of ice melting and sea water expansion from ocean warming will likely cause the global average sea-level to rise by between 0.1 and 0.9 meters between 1990 and 2100. In colder climates, such warming could bring longer growing seasons and less severe winters. Those in coastal communities, many in developing nations, will experience increased flooding due to sea level rise and are likely to experience more severe storms and surges. In the Arctic regions, where temperatures have risen more than the global average, the landscape and ecosystems are being altered rapidly. ...
The Earth is warming
The most striking evidence of a global warming trend ... show a relatively rapid increase in temperature, particularly over the past 30 years. ... records ... indicate that global mean surface air temperature increased about 0.7F (0.4C) since the early 1970’s. Although the magnitude of warming varies locally, the warming trend is spatially widespread and is consistent with an array of other evidence ...
Laboratory measurements of gases trapped in dated ice cores have shown that for hundreds of thousands of years, changes in temperature have closely tracked with atmospheric carbon dioxide concentrations. Burning fossil fuel for energy, industrial processes, and transportation releases carbon dioxide to the atmosphere. Carbon dioxide in the atmosphere is now at its highest level in 400,000 years and continues to rise. Nearly all climate scientists today believe that much of Earth’s current warming has been caused by increases in the amount of greenhouse gases in the atmosphere. The degree of confidence in this conclusion is higher today than it was 10, or even 5 years ago, but uncertainties remain. As stated in the Academies 2001 report, “the changes observed over the last several decades are likely mostly due to human activities, but we cannot rule out that some significant part of these changes is also a reflection of natural variability.”

Cicerone statements demonstrate reality. Mankind is contributing seriously to global warming. The questions that wacko extremists want to halt and distort: "how much and how destructive". Good people would ask such questions. Fools would insist that global warming does not even exist - as a mental midget president even tried to claim in 2001 and 2002.
Those who deny global warming have a political agenda as demonstrated by the pathetically bad rationalization in that caranddriver.com article. An article with such bad logic that a ferocious challenge is required. xoxoxoBruce I make no apologies for accurately defining the integrity of that article by challenging it accordingly - ferociously.
