Scientist: Forget Global Warming, Prepare for New Ice Age
Wednesday, April 23, 2008



Sunspot activity has not resumed up after hitting an 11-year low in March last year, raising fears that — far from warming — the globe is about to return to an Ice Age, says an Australian-American scientist.

Physicist Phil Chapman, the first native-born Australian to become an astronaut with NASA [he became an American citizen to join up, though he never went into space], said pictures from the U.S. Solar and Heliospheric Observatory (SOHO) showed no spots on the sun.

He said the world cooled quickly between January last year and January this year, by about 0.7 degrees Centigrade.

"This is the fastest temperature change in the instrumental record, and it puts us back to where we were in 1930," Chapman wrote in The Australian Wednesday. "If the temperature does not soon recover, we will have to conclude that global warming is over."

[Critics quickly pointed out that Chapman may have been "cherry-picking" the data. A strong La Nina formation in the Pacific pushed down January temperatures over much of the Northern Hemisphere from where they had been a year earlier, but average global temperatures are still much higher than the 20th-century average, and the NOAA said last week that last month was the warmest March on record.]

The Bureau of Meteorology says temperatures in Australia have been warmer than the 1960-90 average since the late 1970s, barring a couple of cooler years, and are now 0.3 degrees Centigrade higher than the long-term average.

A sunspot is a region on the sun that is cooler than the rest and appears dark.

An alternative theory of global warming is that a strong solar magnetic field, when there is plenty of sunspot activity, protects the Earth from cosmic rays, cutting cloud formation, but that when the field is weak — during low sunspot activity — the rays can penetrate into the lower atmosphere and cloud cover increases, cooling the surface.

But scientists from the U.S. National Centre for Atmospheric Research in Bolder, Colorado published a report in 2006 that showed the sun had a negligible effect on climate change.

The researchers wrote in the journal Nature that the sun's brightness varied by only 0.07 percent over 11-year sunspot cycles, and that that was far too little to account for the rise in temperatures since the Industrial Revolution.

Chapman proposes preventive, or delaying, moves to slow the cooling, such as bulldozing Siberian and Canadian snow to make it dirty and less reflective.

"My guess is that the odds are now at least 50:50 that we will see significant cooling rather than warming in coming decades," he writes.

That's it. This summer I'm going to put that ski lift I've been thinking about on my hill. Investors welcome.

If you build it they will come.

Hey rocket scientists. Wouldn't that be perfect example of global warming? The earths crust heats up leading to more evaporation thus causing more precipitation which would produce more snow which in turn makes colder temps on the surface?

Here is that Graph of the Satellite data. Notice the large drop between January 2007 and January 2008. This is the drop in temperature that is mentioned. The difference between those two. Has that low temperature drop been maintained any bettor than the 2004 summer drop of temperatures? As you can see there is already a rebound in February and March.

This is just my opinion. We had OLD POLAR ICE melt, the size of the state of California, melt. In addition the arctic had its smallest size. In order for that ice to melt, the energy for the heat of fusion, has to be supplied. It comes from the atmosphere. When that heat is transferred to melting ice there is less energy for higher temperatures. But the CO 2 didn't go down in the meantime so temperatures will build again until there is a run on melting OLD POLAR ICE again a few years down the road.

I do admit that sunspot activity is low and that does help moderate temperatures. I am not holding my breath (for you deniers) and if sunspot activity increases than things will get hotter still.

“...civilization will end within 15 or 30 years unless immediate action is taken against problems facing mankind,” biologist George Wald, Harvard University, April 19, 1970.

By 1995, “...somewhere between 75 and 85 percent of all the species of living animals will be extinct.” Sen. Gaylord Nelson, quoting Dr. S. Dillon Ripley, Look magazine, April 1970.

Because of increased dust, cloud cover and water vapor “...the planet will cool, the water vapor will fall and freeze, and a new Ice Age will be born,” Newsweek magazine, January 26, 1970.

The world will be “...eleven degrees colder in the year 2000. This is about twice what it would take to put us into an ice age,” Kenneth Watt, speaking at Swarthmore University, April 19, 1970.

“We are in an environmental crisis which threatens the survival of this nation, and of the world as a suitable place of human habitation,” biologist Barry Commoner, University of Washington, writing in the journal Environment, April 1970.

“Man must stop pollution and conserve his resources, not merely to enhance existence but to save the race from the intolerable deteriorations and possible extinction,” The New York Times editorial, April 20, 1970.

“By 1985, air pollution will have reduced the amount of sunlight reaching earth by one half...” Life magazine, January 1970.

“Population will inevitably and completely outstrip whatever small increases in food supplies we make,” Paul Ehrlich, interview in Mademoiselle magazine, April 1970.

“...air pollution...is certainly going to take hundreds of thousands of lives in the next few years alone,” Paul Ehrlich, interview in Mademoiselle magazine, April 1970.
Ehrlich also predicted that in 1973, 200,000 Americans would die from air pollution, and that by 1980 the life expectancy of Americans would be 42 years.

“It is already too late to avoid mass starvation,” Earth Day organizer Denis Hayes, The Living Wilderness, Spring 1970.

“By the year 2000...the entire world, with the exception of Western Europe, North America and Australia, will be in famine,” Peter Gunter, North Texas State University, The Living Wilderness, Spring 1970.

The problem with what I consider the arrogance of humanity. We look at a couple of year long picture and think we know what has been happening for the last 4.5 billion years and what will happen in the future. Maybe if we could accurately point to trends over the last 2-3 thousand years (with the kind of data we have for the last century) we could have a chance at being able to predict what is going on. Otherwise, as Joe's post shows, we are all just shooting in the dark here.

Probably the best evidence against Global Warming is that Bush agrees.
If that doesn’t give environmentalists reason to rethink they’re positions nothing will. ;)

The difference between 1972 and now as far as Global Warming is that we are now even more confident about GW. Within the Scientific Journals for all of the 1970's, 65% of the article dealing with future temperature change indicated that it would go up and usually from CO 2. Only 10% suggested that temperatures would go down do to Celestial Mechanics related to Ice Age.
That is comparison with the last 10 years where the numbers are 95% rising temperature and no articles suggesting lower temperatures.

So while one may have been able to find credentialed people to quote for popular magazines and environmental concerns about diversity in the 1970's, it didn't come close to being a consensus that it would get colder at all. Even then the "vote" was higher temperatures and today it is assured as any scientists can be that temperatures will rise and it is do to increase in Greenhouse Gases.

April 30 (Bloomberg) -- Parts of North America and Europe may cool naturally over the next decade, as shifting ocean currents temporarily blunt the global-warming effect caused by mankind, Germany's Leibniz Institute of Marine Sciences said.

Average temperatures in areas such as California and France may drop over the next 10 years, influenced by colder flows in the North Atlantic, said a report today by the institution based in Kiel, Germany. Temperatures worldwide may stabilize in the period.

The study was based on sea-surface temperatures of currents that move heat around the world, and vary from decade to decade. This regional cooling effect may temporarily neutralize the long- term warming phenomenon caused by heat-trapping greenhouse gases building up around the earth, said Richard Wood, a research scientist at the Met Office Hadley Centre, a U.K. provider of environmental and weather-related services.

``Those natural climate variations could be stronger than the global-warming trend over the next 10-year period,'' Wood said in an interview. ``Without knowing that, you might erroneously think there's no global warming going on.''

The Leibniz study, co-written by Noel Keenlyside, a research scientist at the institute, will be published in the May 1 issue of the journal Nature.

``If we don't experience warming over the next 10 years, it doesn't mean that greenhouse-gas warming is not with us,'' Keenlyside said in an interview. ``There can be natural fluctuations that may mask climate change in the short term.''

CO2 Surge

Carbon dioxide, produced mainly from burning fossil fuels such as oil and natural gas, is the chief pollutant blamed for global warming. Since 1988, CO2 levels in the world's skies have increased by 9.8 percent, according to the U.S. National Oceanic and Atmospheric Administration.

Scientists debate how much carbon can be pumped into the atmosphere before the effects of climate change, including droughts, floods and reduced fresh water supplies, become irreversible. For every 1 million molecules in the atmosphere, about 384 are carbon dioxide, according to NOAA.

Global temperatures can't rise by more than 2 degrees Celsius (3.6 Fahrenheit) without risking the worst effects of climate change, according to the European Union. A scenario to stay below that limit suggests that CO2 levels must be stabilized between 350 and to 400 parts per million.

Long-term climate changes in the North Atlantic region affect ``hurricane activity in the Atlantic, and surface temperature and rainfall variations over North America, Europe and northern Africa,'' according to the study.

`Cold Direction'

``Natural variations over the next 10 years might be heading in the cold direction,'' Wood said. ``If you run the model long enough, eventually global warming will win.''

The world will become at least 2.5 degrees Celsius warmer by 2100, compared with the pre-industrial period, Rajendra Pachauri, chairman of the Intergovernmental Panel on Climate Change, said in March.

``We thought a lot about the way to present this because we don't want it to be turned around in the wrong way,'' Keenlyside said. ``I hope it doesn't become a message of Exxon Mobil and other skeptics.''

Exxon Mobil Corp. spokesman Gantt Walton said managers of U.S. oil company ``take the issue of climate change seriously and the risks warrant action,'' in an interview today.

I'm sure that this is not how those scientists would like their data presented... LOL

Global cooling appears to be the “flavour of the month”. First, a rather misguided media discussion erupted on whether global warming had stopped, based on the observed temperatures of the past 8 years or so (see our post). Now, an entirely new discussion is capturing the imagination, based on a group of scientists from Germany predicting a pause in global warming last week in the journal Nature (Keenlyside et al. 2008).
Specifically, they make two forecasts for global temperature, as discussed in the last paragraphs of their paper and shown in their Figure 4 (see below). The first forecast concerns the time interval 2000-2010, while the second concerns the interval 2005-2015 (*). For these two 10-year averages, the authors make the following prediction:

“… the initialised prediction indicates a slight cooling relative to 1994-2004 conditions”

Their graph shows this: temperatures in the two forecast intervals (green points shown at 2005 and 2010) are almost the same and are both lower than observed in 1994-2004 (the end of the red line in their graph).

The authors also make regional predictions, but naturally it was this global prediction that captivated most newspaper stories around the world (e.g. BBC News, Reuters, Bloomberg and so on), because of its seeming contradiction with global warming. The authors emphasise this aspect in their own media release, which was titled: Will Global Warming Take a Short Break?

That this cooling would just be a temporary blip and would change nothing about global warming goes without saying and has been amply discussed elsewhere (e.g. here). But another question has been rarely discussed: will this forecast turn out to be correct?

We think not – and we are prepared to bet serious money on this. We have double-checked with the authors: they say they really mean this as a serious forecast, not just as a methodological experiment. If the authors of the paper really believe that their forecast has a greater than 50% chance of being correct, then they should accept our offer of a bet; it should be easy money for them. If they do not accept our bet, then we must question how much faith they really have in their own forecast.

The bet we propose is very simple and concerns the specific global prediction in their Nature article. If the average temperature 2000-2010 (their first forecast) really turns out to be lower or equal to the average temperature 1994-2004 (*), we will pay them € 2500. If it turns out to be warmer, they pay us € 2500. This bet will be decided by the end of 2010. We offer the same for their second forecast: If 2005-2015 (*) turns out to be colder or equal compared to 1994-2004 (*), we will pay them € 2500 – if it turns out to be warmer, they pay us the same. The basis for the temperature comparison will be the HadCRUT3 global mean surface temperature data set used by the authors in their paper.

To be fair, the bet needs an escape clause in case a big volcano erupts or a big meteorite hits the Earth and causes cooling below the 1994-2004 level. In this eventuality, the forecast of Keenlyside et al. could not be verified any more, and the bet is off.

The bet would also need a neutral arbiter – we propose, for example, the director of the Hadley Centre, home of the data used by Keenlyside et al., or a committee of neutral colleagues. This neutral arbiter would also decide whether a volcano or meteorite impact event is large enough as to make the bet obsolete.

We will discuss the scientific reasons for our assessment here another time – first we want to hear from Keenlyside et al. whether they accept our bet. Our friendly challenge is out – we hope they will accept it in good sportsmanship.

(*) We adopt here the definition of the 10-year intervals as in their paper, which is from 1 November of the first year to 31 October of the last year. I.e.: 2000-2010 means means 1 November 2000 until 31 October 2010.
