Lay and Enron became synonymous with corporate abuse and accounting fraud when the scandal broke in 2001. Lay was the CEO and chairman of Enron from 1985 until his resignation on January 23, 2003, except for a few months in 2000 when he was chairman and Jeffrey Skilling was CEO.
On July 7, 2004, Lay was indicted by a grand jury on 11 counts of securities fraud and related charges

Here's some scientific statements we should all consider (if nothing else, read the first one):
John Christy, professor of atmospheric science and director of the Earth System Science Center at the University of Alabama in Huntsville, contributor to several IPCC reports
I'm sure the majority (but not all) of my IPCC colleagues cringe when I say this, but I see neither the developing catastrophe nor the smoking gun proving that human activity is to blame for most of the warming we see. Rather, I see a reliance on climate models (useful but never "proof") and the coincidence that changes in carbon dioxide and global temperatures have loose similarity over time.
Tim Patterson, paleoclimatologist and Professor of Geology at Carleton University in Canada
There is no meaningful correlation between CO2 levels and Earth's temperature over this [geologic] time frame. In fact, when CO2 levels were over ten times higher than they are now, about 450 million years ago, the planet was in the depths of the absolute coldest period in the last half billion years. On the basis of this evidence, how could anyone still believe that the recent relatively small increase in CO2 levels would be the major cause of the past century's modest warming?
Don Easterbrook, emeritus professor of geology, Western Washington University
global warming since 1900 could well have happened without any effect of CO2. If the cycles continue as in the past, the current warm cycle should end soon and global temperatures should cool slightly until about 2035
Chris de Freitas, Associate Professor, School of Geography, Geology and Environmental Science, University of Auckland
There is evidence of global warming. ... But warming does not confirm that carbon dioxide is causing it. Climate is always warming or cooling. There are natural variability theories of warming. To support the argument that carbon dioxide is causing it, the evidence would have to distinguish between human-caused and natural warming. This has not been done.
Richard Lindzen, Alfred P. Sloan Professor of Atmospheric Science at the Massachusetts Institute of Technology and member of the National Academy of Sciences
We are quite confident (1) that global mean temperature is about 0.5 °C higher than it was a century ago; (2) that atmospheric levels of CO2 have risen over the past two centuries; and (3) that CO2 is a greenhouse gas whose increase is likely to warm the earth (one of many, the most important being water vapor and clouds). But – and I cannot stress this enough – we are not in a position to confidently attribute past climate change to CO2 or to forecast what the climate will be in the future. [T]here has been no question whatsoever that CO2 is an infrared absorber (i.e., a greenhouse gas – albeit a minor one), and its increase should theoretically contribute to warming. Indeed, if all else were kept equal, the increase in CO2 should have led to somewhat more warming than has been observed.
American Institute of Professional Geologists
The geological professionals in AIPG recognize that climate change is occurring and has the potential to yield catastrophic impacts if humanity is not prepared to address those impacts. It is also recognized that climate change will occur regardless of the cause. The sooner a defensible scientific understanding can be developed, the better equipped humanity will be to develop economically viable and technically effective methods to support the needs of society.
The American Association of State Climatologists
Climate prediction is difficult because it involves complex, nonlinear interactions among all components of the earth’s environmental system.... The AASC recognizes that human activities have an influence on the climate system. Such activities, however, are not limited to greenhouse gas forcing and include changing land use and sulfate emissions, which further complicates the issue of climate prediction. Furthermore, climate predictions have not demonstrated skill in projecting future variability and changes in such important climate conditions as growing season, drought, flood-producing rainfall, heat waves, tropical cyclones and winter storms. These are the type of events that have a more significant impact on society than annual average global temperature trends. Policy responses to climate variability and change should be flexible and sensible – The difficulty of prediction and the impossibility of verification of predictions decades into the future are important factors that allow for competing views of the long-term climate future. Therefore, the AASC recommends that policies related to long-term climate not be based on particular predictions, but instead should focus on policy alternatives that make sense for a wide range of plausible climatic conditions regardless of future climate... Finally, ongoing political debate about global energy policy should not stand in the way of common sense action to reduce societal and environmental vulnerabilities to climate variability and change. Considerable potential exists to improve policies related to climate.

That is a blog... Certainly not a credible source of peer-reviewed information.
And volcanoes are not the only source of natural CO2 on this planet, and in fact natural sources of CO2 combined are a lot more than the anthropogenic factor. But then again this is another fact the AGW believers like to leave out....

You see this is what is so utterly ridiculous about denialists - - random quotes, no context, no links, and above all NO DATES. The only dates available are inside the quotes and these generally appear to be from 20 years ago - all copy and pasted do doubt from some template response of 6 quotes which are all that are needed in the face of almost universal and total agreement on this issue - even from the most ardent denialists - absolutely mind numbingly ridiculous.

An "Executive Summary" by the U.S. Climate Change Science Program, co-authored by John Christy of UAH concludes:
"Previously reported discrepancies between the amount of warming near the surface and higher in the atmosphere have been used to challenge the reliability of climate models and the reality of human induced global warming. This significant discrepancy no longer exists because errors in the satellite and radiosonde data have been identified and corrected."
Until science proves that CO2 causes global warming (with empirical data and observation), there is little point in isolating the cause for a compound that no one knows whether or not it's causing a problem.
