Cool. Some of your earlier posts made me doubt this.
Agreed. However, if the relevant science is not definitive and the EPA want to publish a report saying that the US government believes it to be definitive, what would you do?
On this note, I think I owe everyone a slight retraction. I have been arguing about Global Warming from my own perspective. I have not delved too deeply into the administration’s perspective. That is, the objections I have raised were not intended to be my interpretation of the administration’s position.
Having said that, I did look into the White House’s position. They appear to agree substantially with you, jshore that it is real phenomena and possibly of human origin. I found This cite from the whitehouse indicating that they agree with an NAS study. As in “*My Cabinet-level working group has met regularly for the last 10 weeks to review the most recent, most accurate, and most comprehensive science. They have heard from scientists offering a wide spectrum of views. They have reviewed the facts, and they have listened to many theories and suppositions. The working group asked the highly-respected National Academy of Sciences to provide us the most up-to-date information about what is known and about what is not known on the science of climate change. *”
and
“First, we know the surface temperature of the earth is warming. It has risen by .6 degrees Celsius over the past 100 years. There was a warming trend from the 1890s to the 1940s. Cooling from the 1940s to the 1970s. And then sharply rising temperatures from the 1970s to today.”
and finally,
"*There is a natural greenhouse effect that contributes to warming. Greenhouse gases trap heat, and thus warm the earth because they prevent a significant proportion of infrared radiation from escaping into space. Concentration of greenhouse gases, especially CO2, have increased substantially since the beginning of the industrial revolution. And the National Academy of Sciences indicate that the increase is due in large part to human activity.
Yet, the Academy's report tells us that we do not know how much effect natural fluctuations in climate may have had on warming. We do not know how much our climate could, or will change in the future. We do not know how fast change will occur, or even how some of our actions could impact it. *"
Now, let’s look at the leaked memo from the EPA which says in part:
“Natural variability is used to mask scientific consensus that most of the recent temperature increase is likely due to human activities”
Finally, just in case the speech mis characterized the NAS reoport, I found This summary of an NAS report (although I admit I have no idea if it is the one reffered to in the speech.) It says in part “*The IPCC’s conclusion that most of the observed warming of the last 50 years is likely to have been due to the increase in greenhouse gas concentrations accurately reflects the current thinking of the scientific community on this issue. The stated degree of confidence in the IPCC assessment is higher today than it was 10, or even 5 years ago, but uncertainty remains because of (1) the level of natural variability inherent in the climate system on time scales of decades to centuries, (2) the questionable ability of models to accurately simulate natural variability on those long time scales, and (3) the degree of confidence that can be placed on reconstructions of global mean temperature over the past millennium based on proxy evidence. Despite the uncertainties, there is general agreement that the observed warming is real and particularly strong within the past 20 years. Whether it is consistent with the change that would be expected in response to human activities is dependent upon what assumptions one makes about the time history of atmospheric concentrations of the various forcing agents, particularly aerosols. *”
So, what do we have. We have a part of an EPA report over which the EPA and the WhitHouse (via the Council on Environmental Quality CEQ and Office of Management and Budget OMB) disagreed. They negotiated over it for months with little change. Finally the WhiteHouse made edits and said that “no further changes may be made”. The authours of the memo (of whom we know nothing) cried foul in part for the reason quoted above (in addition to others). these disagreements amounted to (in the opinion of the memo’s author) changes which caused the Report On the Environment ROE to “no longer accurately represents scientific consensus on climate change.”
I have not mentioned the two studies that the administration wanted referenced (I still do not have a good link describing them, only a criptic mention by jshore).
I should also point out, that the report in question is meant to “identif[y] indicators that can be used to measure EPA progress in protecting human health and the environment.” The section which was under contention was a small part of it. Also it should be noted that neither the report nor the section under contention was a “peer reviewed” study of any kind (to my knowledge. If you know different, please let me know). So, even at its worse, this complaint is not the same as the EPA measuring some phenomena and the administration demanding that the number be changed. That is, we are not talking about disregarding the scientific method for other means of knowledge (which you certainly meant to imply with your creaionism and HIV does nto cause aids jibes). We are talking about summaries and characterizations.
So, what happened here? Did the big bad administration demand irrational changes to a scientific paper while the noble scientists defended reason? Did the (did you use the word pinko, jshore)buerocratic government agency attempt to mislead the public while the Bush administration insist on reason?
I don’t know.
Given that the only news we have of the incident comes from critics of the administration, we should at the least take them with a grain of salt. Given that the only news we have of the incident come to us in a packages designed (by strong critics of the administration) to discredit the administration’s oversight of scientific agencies, perhaps another grain of salt is in order. But, given that absolutely no other alternative explanation (except the first one I made up) is postulated at all by the people presenting the incident, I’d say, we have to take it with a shaker of salt.
Now, having said all that, I’d like to point out one other part of the memo in question. “Conclusions of the NRC (2001) are discarded, that multiple studies indicate recent warming is unusual.” Taken at face value, this seems odd. If the studies were mentioned as in (this study said such and such), I can’t see why all mention of them should be removed. Even if the language was more glowing such as “these studies prove we were right and you were wrong, neener, neener.” It seems a more appropriate course would have been to simply mention then and tone down the characterization, or interpretation of them.
I’m still hoping that someone will dig up a copy of the unreleased section of the report. If we found such a paper with the edits and without them, we could discuss them more rationally. Until then, all we have are political attacks. Personally, I’m not inclined to accept such things without a good deal of critical thinking. But, each to his own, I suppose.
