At Harvard and Vanderbilt, Mr. Gore continued bumbling along. |
As a Harvard sophomore, scholar Al "earned" a D in Natural Sciences 6 in a course presciently named "Man's Place in Nature." That was the year he evidently spent more time smoking cannabis than studying its place among other plants within the ecosystem. His senior year, Mr. Gore received a C+ in Natural Sciences 118.
At Vanderbilt divinity school, Mr. Gore took a course in theology and natural science. The assigned readings included the apocalyptic, and widely discredited "Limits to Growth," which formed much of the foundation for "Earth in the Balance." It is said that Mr. Gore failed to hand in his book report on time. Thus, his incomplete grade turned into an F, one of five Fs Mr. Gore received at divinity school, which may well be a worldwide record.

|Fears that two-thirds of the world's polar bears will die off in the next 50 years are overblown, says Mitchell Taylor, the Government of Nunavut's director of wildlife research. [...] While he agrees that seals are essential food for bears as they fatten up during the spring and summer months - seal blubber makes up half of the bears' energy intake - he also suspects bears will be able to supplement their diet with other foods, such as walrus. During the summer months polar bears may also forage on berries, sedges and other plants, as well as bird eggs, to supplement their diet. And Taylor also points out female polar bears go nine months without eating at all during pregnancy. Besides, Taylor says he and numerous Inuit hunters have seen bears catch seal without the presence of sea ice. Bears sometimes find a place on shore to pounce on seals swimming by. Or they may catch seals caught in tidal pools, or sneak up on their prey at night. Taylor even suggests polar bears may float still on the water to fool seals into thinking they are hunks of sea ice.|

The continuing rapid increase in carbon dioxide concentrations during the past 10-15 years has apparently been unable to overrule the °attening of the temperature trend as a result of the Sun settling at a high, but no longer increasing, level of magnetic activity.

Thus, the public perception that the hockeystick as truthfully describing the temperature history was definitely false.

The real world is muddy and messy and full of things that we do not yet understand.

|QUOTE (Freeman Dyson - Professor Emeritus of Physics - Princeton University)|
|Prof. Dyson explains that the many components of climate models are divorced from first principles and are "parameterized" -- incorporated by reference to their measured effects.|
"They are full of fudge factors that are fitted to the existing climate, so the models more or less agree with the observed data. But there is no reason to believe that the same fudge factors would give the right behaviour in a world with different chemistry, for example in a world with increased CO2 in the atmosphere," he states.
Prof. Dyson learned about the pitfalls of modelling early in his career, in 1953, and from good authority: physicist Enrico Fermi, who had built the first nuclear reactor in 1942. The young Prof. Dyson and his team of graduate students and post-docs had proudly developed what seemed like a remarkably reliable model of subatomic behaviour that corresponded with Fermi's actual measurements. To Prof. Dyson's dismay, Fermi quickly dismissed his model.
"In desperation, I asked Fermi whether he was not impressed by the agreement between our calculated numbers and his measured numbers. He replied, 'How many arbitrary parameters did you use for your calculations?' I thought for a moment about our cut-off procedures and said, 'Four.' He said, 'I remember my friend Johnny von Neumann [the co-creator of game theory] used to say, with four parameters I can fit an elephant, and with five I can make him wiggle his trunk.' With that, the conversation was over."
Prof. Dyson soon abandoned this line of inquiry. Only years later, after Fermi's death, did new developments in science confirm that the impressive agreement between Prof. Dyson's model and Fermi's measurements was bogus, and that Prof. Dyson and his students had been spared years of grief by Fermi's wise dismissal of his speculative model. Although it seemed elegant, it was no foundation upon which to base sound science.

|...Climate prediction is complex with many uncertainties – The AASC recognizes climate prediction is an extremely difficult undertaking. For time scales of a decade or more, understanding the empirical accuracy of such predictions – called “verification” – is simply impossible, since we have to wait a decade or longer to assess the accuracy of the forecasts.|
Climate prediction is difficult because it involves complex, nonlinear interactions among all components of the earth’s environmental system. These components include the oceans, land, lakes, and continental ice sheets, and involve physical, biological, and chemical processes. The complicated feedbacks and forcings within the climate system are the reasons for the difficulty in accurately predicting the future climate. 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. Climate is always changing on a variety of time scales and being prepared for the consequences of this variability is a wise policy.

Changes in the land surface also change the surface water and energy budgets act to redirect the incoming solar energy. Humans alter land surface characteristics through irrigation practices, removal and reintroduction of forests, agricultural changes to vegetative cover, reduction of soil water recharge by soil compaction, and modification of heat storage by cities and reservoirs. Many of these lead to changes in the reflectivity of the surface. ...such changes can have significant effects on regional and local climate patterns.

Weather predictions beyond a few days are nowadays based on ensembles of simulations that estimate the range of probable outcomes. The same ensemble concept is used for projections of climate change, where uncertainty arises from the limitations of models and from the emission scenarios used to represent the effects of human activity.

Land-use change is another important human-induced regional forcing factor, but accurate histories of land-use change are spotty and estimates of future land-use changes are very difficult. [...]
Cloud feedback may also be very important, but its magnitude and even its sign remain uncertain. Climate-induced changes of the land surface may in turn feed back on the climate itself. Many processes are involved, including changes in soil characteristics (e.g., soil moisture, holding capacity), vegetation, radiative characteristics (e.g., albedo), and surface-atmosphere exchanges of water vapor, other gases (e.g., CO2), particulates (e.g., dust) and momentum. Some of these processes remain poorly understood and difficult to measure and model, and thus require continued research. The full suite of potentially important feedback processes is yet to be adequately understood and quantified. For example, although observations of global mean temperatures indicate that the surface has warmed by about 0.6°C over the past 100 years, the mean tropospheric temperature trends, for which we have observations only over the past 40 years or so, are more complex and not well understood. Although there remains significant observational uncertainties, global mean tropospheric temperatures warmed faster in the 1960s and 1970s, and slower in the 1980s and 1990s, than the global mean surface temperature. These differences indicate the need for research into feedback processes that might explain this reversal in tropospheric temperature trends. Additional poorly understood feedbacks of potential importance are carbon cycle feedback, due to warming-induced changes in the land and ocean carbon reservoirs; atmospheric chemistry feedback, due to chemical interactions affecting ozone concentrations, aerosol formation, and atmospheric heating profiles; and ocean circulation feedback, arising from ocean circulation changes that affect ocean-atmosphere heat and freshwater exchange.

|The boy has drawn, in his third-grade class, a global warming timeline that is his equivalent of the mushroom cloud. Alex Hendel of Arlington County is talking about the end of life on our beleaguered planet. Looking up to make sure his mother is following along, he taps the final stripe, which is so sparsely dotted it is almost invisible. "In 20 years," he pronounces, "there's no oxygen." Then, to dramatize the point, he collapses, "dead," to the floor.|
|Founded in 1970 as a loose assortment of Canadian anti-nuclear agitators, American expatriates, and underground journalists calling themselves the "Don't Make a Wave Committee," Greenpeace is today the most influential group of the environmental Left. [...] |
In the early 1990s, the organization turned its attention to the purported threat that chlorine posed to the world's water supplies. At the time, Greenpeace asserted that it would accept nothing less than the blanket prohibition of the element. "There are no uses of chlorine which we regard as safe," declared Greenpeace activist Joe Thornton, [...]
Greenpeace co-founder Patrick Moore left the organization and now laments that the group has become "dominated by leftwingers and extremists who disregard science in the pursuit of environmental purity."
According to a December 20, 2005 New York Times report, "the F.B.I. investigated possible financial ties between [Greenpeace] members and militant groups like the Earth Liberation Front and the Animal Liberation Front." [...]
An expose of Greenpeace's fundraising practices carried out in 2003 by Public Interest Watch (PIW), a nonprofit watchdog group, led to a report disclosing that Greenpeace uses its Greenpeace Fund, a tax-exempt entity debarred from engaging in political advocacy and lobbying by the IRS tax code, to illegally direct funds to Greenpeace Inc., a tax-exempt organization permitted to engage in lobbying and advocacy but not to accept tax-deductible funds. PIW calculated that in 2000, $4.25 million was provided by the Greenpeace Fund in this way.
Greenpeace is heavily funded by many foundations, among which are the John D. and Catherine T. MacArthur Foundation, the Rockefeller Brothers Fund, the Bauman Family Foundation, the Blue Moon Fund, the Columbia Foundation, the Compton Foundation, the Minneapolis Foundation, the Nathan orgasmings Foundation, the Scherman Foundation, Ted Turner's Turner Foundation. The organization has also drawn support from numerous celebrities, including singers Sting, Tom Jones, and Elton John, who have sponsored its "save the rainforest" campaigns. In 2004, Greenpeace received $15,844,752 in grants, and held net assets of $1,893,548. That same year, the Greenpeace Fund received grants totaling $6,866,534 and held net assets of $7,532,018.
|Greenpeace was originally the brainchild of the radical “Don’t Make a Wave Committee,” a group of American draft-dodgers who fled to Vancouver in 1969 and, supported by money from anti-war Quaker organizations, got into the business of forcibly blocking American nuclear tests. Over the years the group has loudly made its feelings known on a variety of issues (nuclear testing, whaling, and global warming, for instance), and its Amsterdam-based activist moguls pull the strings on what is estimated to be a $360 million global empire.|
Here in the United States, however, Greenpeace is a relatively modest activist group, spending about $10 million per year. And the lion’s share of that budget in recent years has gone to outrageous attempts to smear agricultural biotech products and place doubts about the safety of genetically improved foods in the minds of American consumers. [...]
Patrick Moore was one of a dozen or so activists who founded Greenpeace in the basement of a Unitarian Church in Vancouver. Within 7 years, the organization had footholds in over two dozen countries and a $100 million budget. As eco-activists in general found themselves suddenly invited into the meeting-places of business and government, Greenpeace made the decision to take even more extreme positions, rather than being drawn in to collaboration with their former enemies.
Moore broke with his comrades during this period, and has emerged as an articulate critic of his former brainchild. Referring to Greenpeace’s “eco-extremism” in March 2000, he described the group in Oregon Wheat magazine as “Anti-human”; “antitechnology and anti-science”; “Anti-organization” and “pro-anarchy”; “anti-trade”; “anti-free-enterprise”; “anti-democratic”; and “basically anti-civilization.”
Writing in Canada’s National Post in October 2001, Patrick Moore offered the following critique: “I had no idea that after I left in 1986 they would evolve into a band of scientific illiterates…. Clearly, my former Greenpeace colleagues are either not reading the morning paper or simply don't care about the truth.”

|The Union of Concerned Scientists (UCS) is a nonprofit environmental advocacy organization with more than 100,000 members. Seeing its mission as building a "cleaner, healthier environment and a safer world," ... It opposes genetically engineered foods, condemns SUV vehicles, and proposes measures aimed at combating what it deems the imminent dangers of global warming. It also opposes the vast majority of American foreign policy decisions, and calls for a unilateral reduction in U.S. nuclear weapons stockpiles. UCS disseminates to lawmakers and news outlets its opinions about each of these matters, with the intent of ultimately influencing public policy.|
Students and faculty members at the Massachusetts Institute of Technology founded UCS in 1969. "Through its actions in Vietnam, our government has shaken our confidence in its ability to make wise and humane decisions," reads the UCS founding document. That sentiment continues to this day, with UCS condemning American efforts in the War on Terror and the 2003 War in Iraq.
UCS typically minimizes threats posed by foreign rogue regimes, and challenges U.S. assertions about the intentions and military capacities of those governments. In 1998, for instance, UCS assured the public that American analysts had exaggerated North Korea's ability to produce nuclear weapons, and that the Pyongyang regime was still many years away from being able to develop such an arsenal.
UCS vigorously opposes America's development of a missile defense system. It also calls for the "adoption of a U.S. nuclear no-first-use policy"; "a U.S. rejection of rapid-launch options, and a change in deployment practices to provide for the launch of U.S. nuclear forces in hours or days rather than minutes"; "the elimination of all U.S. 'tactical' nuclear weapons, intended for use on the battlefield"; "verified unilateral reductions to a total of 1,000 strategic warheads (including deployed and stored), accompanied by warhead dismantlement"; and "a commitment to further reductions in the number of nuclear weapons, on a negotiated and verified multilateral basis."
UCS admonishes American corporations such as McDonald's and Burger King, asserting that the presence of antibiotics in meat used by fast-food companies contributes to large-scale antibiotic resistance. In 2003, bills based on UCS research aimed at prohibiting the use of eight classes of antibiotics in livestock used by fast-food producers were introduced in both the U.S. House and Senate. Soon after, UCS admitted that the majority of its claims were speculative. UCS has also warned of the alleged dangers of genetically modified food.
Another issue of concern to UCS is that of global warming. The organization circulated a petition that drew the signatures of some 1,600 scientific experts demanding that the United States ratify the Kyoto Protocol.
A Union of Concerned Scientists declaration, entitled "Restoring Scientific Integrity in Policy Making," charges that the Bush administration "has continued to distort and suppress science in pursuit of its political goals — despite a plea from top U.S. scientists to restore scientific integrity to the policy-making process." According to UCS President Kevin Knobloch, "We found a serious pattern of undermining science by the Bush administration, and it crosses disciplines, whether it's global climate change or reproductive health or mercury in the food chain or forestry -- the list goes on and on." The signers of this document portrayed themselves as objective scientists with no political agenda. But in truth, over half of them were financial contributors to the Democratic Party, Democratic candidates, or a variety of leftist causes. [...]
UCS is a member of the Save Our Environment Action Center, a leftist coalition that describes itself as "a collaborative effort of the nation's most influential environmental advocacy organizations harnessing the power of the internet to increase public awareness and activism on today's most important environmental issues."
UCS has received funding from the Beldon Fund, the Compton Foundation, the Educational Foundation of America, the J.M. Kaplan Fund, the Scherman Foundation, the Blue Moon Fund, the Ford Foundation, the Carnegie Corporation of New York, the Energy Foundation, the William and Flora Hewlett Foundation, the Joyce Foundation, the John D. and Catherine T. MacArthur Foundation, the David and Lucile Packard Foundation, the Turner Foundation, and Pew Charitable Trusts.

|George Monbiot, the environmental campaigner, scourge of the automobile industry and champion of not owning cars, has finally bought himself . . . a car. Notwithstanding pledges to live a green lifestyle and be a model to others, he has given in to temptation and acquired a secondhand Renault. [...]|
In what can only be described as a comprehensive U-turn, Monbiot has chosen a Renault Clio, an economical hatchback but not the most frugal in fuel consumption or carbon emissions. He bought it from a friend for an undisclosed amount. As zealots will be quick to remind him, it emits 115g/km , 10% higher than a Toyota Prius, the petrol-electric hybrid belovedof CO2 of the green movement.
