WASHINGTON, June 10 1986

The rise in carbon dioxide and other gases in the earth's atmosphere will have an earlier and more pronounced impact on global temperature and climate than previously expected, according to evidence presented to a Senate subcommittee today.

Scientists and senators at a hearing by the Environmental Pollution Subcommittee agreed that the dangers of manmade changes in the atmosphere had moved from hypothesis to imminent reality and must be addressed quickly.

They said the rise in temperatures was expected to cause profound climatic changes and raise sea levels substantially.

Witnesses at the hearing also testified that the ozone layer of the upper atmosphere, which protects the earth from the sun's ultraviolet light, is being rapidly depleted by manmade gases, and the increased ultraviolet radiation would result in a rise in skin cancer cases and other ecological damage.

Dr. James E. Hansen of the Goddard Space Flight Center's Institute for Space Studies said research by his institute showed that because of the ''greenhouse effect'' that results when gases prevent heat from escaping the earth's atmosphere, global temperatures would rise early in the next century to ''well above any level experienced in the past 100,000 years.'' Steeper Rise in Next Century

Average global temperatures would rise by one-half a degree to one degree Fahrenheit from 1990 to 2000 if current trends are unchanged, according to Dr. Hansen's findings.

Dr. Hansen said the global temperature would rise by another 2 to 4 degrees in the following decade.

While the effect of small increases in global temperature is now unclear, Andrew Maguire, vice president of the World Resources Institute, a Washington research and policy group, said that the doubling of atmospheric carbon dioxide that is foreseen would cause a rise of 3 to 8 degrees in temperature by the 2030's.

He said this would devastate agriculture in the United States and elsewhere, and would cause a rise in sea level of some 4.5 feet as polar ice melted.

Earlier projections of warming trends had held that they would not occur before the middle of the next century.

One of the reasons that scientists now expect faster and higher temperature rises is the emerging consensus that gases other than the carbon dioxide emitted by the burning of such fossil fuels as coal are playing a major role in the greenhouse effect.

The greenhouse effect is the name given to the phenomenon created when carbon dioxide, methane, chlorofluorocarbons and other gases accumulate in the atmosphere and prevent radiant heat from the sun that has reached the earth's surface from escaping back into space.

Dr. Hansen and other scientists testifying today said there was now broad consensus among scientists that the greenhouse effect was speeding up the increase in global temperatures. Less Urgency in 1983

In 1983 a report by the National Academy of Sciences said the greenhouse effect was a ''cause for concern,'' but concluded that there was time to prepare for its impact.

The academy report projected a doubling of greenhouse gases by the third quarter of the next century.

Dr. Hansen's research, however, found that if there is no change in the current rate of growth, the greenhouse gases would double by the late 2020's.

A report by the Environmental Protection Agency three years ago said the warming trend could start by the 1990's and could reach as much as 4 degrees Fahrenheit by 2040, but this was attacked by President Reagan's science adviser at the time, George A. Keyworth, as ''unnecessarily alarmist.''

Today, the scientists and the senators on the subcommittee asserted that there must be national and international action now to mitigate and deal with the imminent effects of the atmospheric changes taking place as a result of human activity. Chafee Asks Early Action

Senator John H. Chafee, the Rhode Island Republican who is chairman of the subcommittee, quoted a recent assessment by the Department of Energy, which said, ''Human effects on atmospheric composition and the size and operations of the terrestrial ecosystems may yet overwhelm the life-support system crafted in nature over billions of years.''

Senator Chafee said it would be too risky to wait until all the answers about atmospheric changes were known before taking action.

He called for the Reagan Administration to take up the issue at the next international economic summit meeting and also at the President's next meeting with the Soviet leader, Mikhail S. Gorbachev. While the scientists testified today that it would be some time before there was enough data to pinpoint regional climatic changes, it was considered likely that some of today's most productive agricultural areas would become too arid for farming.

They also testified that a ''hole,'' in which the ozone has been reduced by some 40 percent, has formed in the ozone layer over Antarctica.

While many aerosol uses of chlorofluorocarbons have been banned in this country, their use in other applications is increasing, and they continue to be used in aerosols in other countries.

en No increase in CO2 emissions after the year 2000

Laut der Hansen-Prognose müsste die Temperatur gegenüber dem Vergleichs­niveau in den 1970er Jahren um 1,5°C angestiegen sein.

In Wahrheit hat sich die Temperatur jedoch lediglich um 0,6°C erhöht.


Die CO2-Emissionen sind seit dem Jahr 2000 um jährlich etwa 2,5 Prozent angestiegen, so dass wir gemäß dem Hansen-Paper einen Temperatur­anstieg erwarten würden, der stärker als in Modell A ausfallen sollte.

Es ist ersichtlich, dass die von der Hansen-Gruppe 1988 modellierte Temperatur­vorhersage um etwa 150% danebenliegt.

Es ist überaus bedauerlich, dass genau diese Art von Modellierungen von unseren Politikern noch immer als verlässliche Klimavorhersage angesehen wird.

4 Prognosen von Professor Mojib Latif

1990 - 2009

Prof. Latif 1997

Im Jahre 1997 hat der Klimaforscher Mojib Latif in den Sendungen ZDF Hallo Deutschland und DAS! (NDR) Prognosen zu den Wintern der kommenden Jahre abgegeben.

Die Prognosen lauteten folgendermaßen:

"Gemittelt über die nächsten 20 Jahre gehen wir davon aus, dass es eher kälter sein wird."

"Diese Situation (die Nordatlantische Oszillation) hat sich jetzt umgestellt, so dass das Russlandhoch die Überhand über unser Klima gewinnen wird. So das wir davon ausgehen, dass wir innerhalb der nächsten 10 bis 20 Jahre eher mit kühleren Wintern zu rechnen haben."

"Die Nordatlantische Oszillation hat sich in den letzten Jahren umgestellt und wir sind jetzt in einer Phase relativ schwacher Nordatlantischer Oszillation und wir erwarten ähnlich wie in den 60er Jahren relativ kalte Winter in der Zukunft."

Zur globalen Erwärmung sagte er im Jahre 1997

"Daher haben wir es zunächst einmal vor allem mit den natürlichen Klimaschwankungen zu tun, während wir erst in etwa 100 Jahren dann die globale Erwärmung zu spüren bekommen."

2 en No Scientific Forecasts to Support Global Warming

Drs. J. Scott Armstrong and Kesten C. Green were asked by US Senator Inhofe for an analysis of the EPA's proposed policies for greenhouse gases

EPA = U.S. Environmental Protection Agency

  1. No scientific forecasts of the changes in the Earth's climate.

    Currently, the only forecasts are those based on the opinions of some scientists. Computer modeling was used to create scenarios (i.e., stories) to represent the scientists' opinions about what might happen.

    The models were not intended as forecasting models (Trenberth 2007) and they have not been validated for that purpose.

    Since the publication of our paper, no one has provided evidence to refute our claim that there are no scientific forecasts to support global warming.

    We conducted an audit of the procedures described in the IPCC report and found that they clearly violated 72 scientific principles of forecasting (Green and Armstrong 2008). (No justification was provided for any of these violations.)

    For important forecasts, we can see no reason why any principle should be violated. We draw analogies to flying an aircraft or building a bridge or performing heart surgery-given the potential cost of errors, it is not permissible to violate principles.

  2. Improper peer review process.

    To our knowledge, papers claiming to forecast global warming have not been subject to peer review by experts in scientific forecasting.

  3. Complexity and uncertainty of climate render expert opinions invalid for forecasting.

    Expert opinions are an inappropriate forecasting method in situations that involve high complexity and high uncertainty.

    This conclusion is based on over eight decades of research.

    Armstrong (1978) provided a review of the evidence and this was supported by Tetlock's (2005) study that involved 82,361 forecasts by 284 experts over two decades.

    Long-term climate changes are highly complex due to the many factors that affect climate and to their interactions.

    Uncertainty about long-term climate changes is high due to a lack of good knowledge about such things as:

    1. causes of climate change,
    2. direction, lag time, and effect size of causal factors related to climate change,
    3. effects of changing temperatures, and
    4. costs and benefits of alternative actions to deal with climate changes (e.g., CO2 markets).

    Given these conditions, expert opinions are not appropriate for long-term climate predictions.

  4. Forecasts are needed for the effects of climate change.

    Even if it were possible to forecast climate changes, it would still be necessary to forecast the effects of climate changes.

    In other words, in what ways might the effects be beneficial or harmful?

    Here again, we have been unable to find any scientific forecasts-as opposed to speculation-despite our appeals for such studies.

    We addressed this issue with respect to studies involving the possible classification of polar bears as threatened or endangered (Armstrong, Green, and Soon 2008).

    In our audits of two key papers to support the polar bear listing, 41 principles were clearly violated by the authors of one paper and 61 by the authors of the other.

    It is not proper from a scientific or from a practical viewpoint to violate any principles.

    Again, there was no sign that the forecasters realized that they were making mistakes.

  5. Forecasts are needed of the costs and benefits of alternative actions that might be taken to combat climate change.

    Assuming that climate change could be accurately forecast, it would be necessary to forecast the costs and benefits of actions taken to reduce harmful effects, and to compare the net benefit with other feasible policies including taking no action.

    Here again we have been unable to find any scientific forecasts despite our appeals for such studies.

  6. To justify using a climate forecasting model, one would need to test it against a relevant naïve model.

    We used the Forecasting Method Selection Tree to help determine which method is most appropriate for forecasting long-term climate change. A copy of the Tree is attached as Appendix 1.

    It is drawn from comparative empirical studies from all areas of forecasting.

    It suggests that extrapolation is appropriate, and we chose a naïve (no change) model as an appropriate benchmark.

    A forecasting model should not be used unless it can be shown to provide forecasts that are more accurate than those from this naïve model, as it would otherwise increase error.

    In Green, Armstrong and Soon (2008), we show that the mean absolute error of 108 naïve forecasts for 50 years in the future was 0.24°C.

  7. The climate system is stable.

    To assess stability, we examined the errors from naïve forecasts for up to 100 years into the future.

    Using the U.K. Met Office Hadley Centre's data, we started with 1850 and used that year's average temperature as our forecast for the next 100 years.

    We then calculated the errors for each forecast horizon from 1 to 100.

    We repeated the process using the average temperature in 1851 as our naïve forecast for the next 100 years, and so on.

    This "successive updating" continued until year 2006, when we forecasted a single year ahead.

    This provided 157 one-year-ahead forecasts, 156 two-year-ahead and so on to 58 100-year-ahead forecasts.

    We then examined how many forecasts were further than 0.5°C from the observed value.

    Fewer than 13% of forecasts of up to 65-years-ahead had absolute errors larger than 0.5°C.

    For longer horizons, fewer than 33% had absolute errors larger than 0.5°C.

    Given the remarkable stability of global mean temperature, it is unlikely that there would be any practical benefits from a forecasting method that provided more accurate forecasts.

  8. Be conservative and avoid the precautionary principle.

    One of the primary scientific principles in forecasting is to be conservative in the darkness of uncertainty. This principle also argues for the use of the naive no-change extrapolation. Some have argued for the precautionary principle as a way to be conservative. It is a political, not a scientific principle.

    As we explain in our essay in Appendix 2, it is actually an anti-scientific principle in that it attempts to make decisions without using rational analyses. Instead, cost/benefit analyses are appropriate given the available evidence which suggests that temperature is just as likely to go up as down.

    However, these analyses should be supported by scientific forecasts.

    The reach of these models is extraordinary, for example, the CSIRO models are currently being used in Australia to determine water allocations for farmers and to justify the need for an Emissions Trading Scheme (ETS) - the most far-reaching of possible economic interventions.

    Yet, according to Dr Armstrong, these same models violate 72 scientific principles.
