WWF links Australian drought with "Global Warming"
The Economist weighs in to Castles / Henderson attack on IPCC silly scenarios.
MARK COLVIN: There's a new question mark over the extent of global warming today; it comes in the form of calculations by the former head of the Australian Bureau of Statistics, Ian Castles.
He's been going through the figures and assumptions made by the International Panel on Climate Change, and Mr Castles says the economic assumptions made in its two-year old report on global warming are simply wrong.
The forecasts for a severe warming of the earth's surface are tightly linked to economic assumptions, so Mr Castles says his economic analysis casts severe doubt on the scientific predictions.
Economics correspondent Ian Henderson.
IAN HENDERSON: Do you believe that, by the end of the century, developing countries like Zimbabwe, Thailand, Panama, Papua New Guinea, Fiji, Vanuatu and Samoa will all be enjoying average incomes that are higher than Australia's?
If not, then you should be very wary about the International Panel on Climate Change's forecast that, mainly on account of human efforts, the world will be up to 5.8 degrees warmer in 2100.
Former Australian Statistician, and former head of the Federal Finance Department, Ian Castles, certainly does not accept at face value the economic assumptions behind the IPCC's 2001 global warming report.
Assumptions like the ones that would see a host of relatively poor countries overtake Australia's per capita GDP within this century, and that's led Ian Castles to seriously question the official forecasts of greenhouse gas emissions, and of global warming.
IAN CASTLES: In order to make projection of emissions, it's necessary to begin by projecting what's going to happen to the world in the next century, in terms of the real levels of output; how many power stations, how many people around the world are going to have access to electricity, what are they going to use it for.
IAN HENDERSON: Ian Castles objection is that the group putting together the official estimates of growth have got their GDP figures seriously wrong for the developing world.
IAN CASTLES: They've assumed, in fact, that the gap between the rich countries and the poor countries of the world is a good deal wider than in fact it is.
They have then developed a series of scenarios that assume that the gap is substantially closed in the course of the century, and this involves them in making projections in the growth in output in the developing world, which are very high, in fact much higher than the rates of growth that these countries have ever achieved in the past.
IAN HENDERSON: In a nutshell, the IPCC's experts have used exchange rates to convert different nation's incomes to a common base. It's an unsound procedure, according to Ian Castles, one of Australia's most highly respected economists.
He says one example of the sort of economic assumption made by the IPCC is the information it's put on a database about various countries.
IAN CASTLES: Which shows, for example, that the output of South Africa in the year 2100 will be greater than that of the whole world in 1990.
IAN HENDERSON: If Ian Castles is correct, and the IPCC's calculations of economic growth in the developing world are wrong, then that means the IPCC's projections of carbon dioxide emissions generated by economic activity are simply too high.
He concedes that forecasts like those the IPCC has been making are very difficult to get right.
But he says that just means that economists, statisticians and government economic policy-makers must play a much greater role in future in the global warming forecasting business.
If Ian Castles manages to change the IPCC's mind on its economic calculations, he says the organisation is likely to reduce its forecasts for the extent of global warming.
IAN CASTLES: I think it's possible that if the exercise had been done in the way it's been done, but avoiding the particular areas to which I'm drawing attention, that the range of climate change will be changed significantly.
I think it would certainly come down significantly at the top end, the 5.8, and I believe it could also come down at the bottom end, the 1.4 by perhaps as much as half a degree.
IAN HENDERSON: Ian Castles says the IPCC's projections of emissions, and therefore of temperatures, are based on fantastic assumptions, and his aim is to replace that fantasy with some solid reality.
MARK COLVIN: That one's certain to start a debate. Economics correspondent, Ian Henderson.

From Tuesday's Globe and Mail
For the first time in years, the entire surfaces of Lake Superior, Lake
Huron and Lake Erie have
frozen over, according to ice experts at the Canadian Ice Service of Environment Canada.
This winter rarity usually occurs only once a decade, and only for fleeting periods, with the last two big freezes in 1994 and 1982.
"They're all covered with ice. They're 100 per cent covered. That's quite unusual," said Claude Dicaire, senior ice forecaster for the Canadian Ice Service.
The Great Lakes region is not alone in having massive amounts of ice. The Gulf of St. Lawrence has 25 per cent more ice than normal, and the Atlantic coast down to Halifax is covered with sea ice, a tribute to the intensity of the deep winter freeze that has gripped Eastern Canada.
Ice extending as far south as Halifax in the Atlantic is considered as unusual as shoreline-to-shoreline freezing of some of the Great Lakes. Mr. Dicaire said Lakes Superior and Huron froze over for the first time this year on Feb. 27, a finding based on satellite images.
The two massive lakes — the world's second- and fifth-largest by surface area — usually have ice-free areas all winter because the huge volumes of water in them seldom cool enough to allow surface temperatures to drop to the freezing point.
The colder weather that has led to the ice has had other effects. In Eastern Canada, it has helped the skiing and snowmobile industry, which are having one of their best seasons in years.
But the cold has hit homeowners with bigger heating bills. January and February has been 34 per cent colder in Southern Ontario than the same period last year, leading to skyrocketing costs for home heating.
Even the maple-syrup business is having trouble getting off the ground because it is too cold for the sap to run. "We're not doing anything," said Ken McGregor, who has a sugar bush near London. "It's just way too cold."
Ice is not unusual on Lake Erie, the shallowest and most prone to freezing
of the Great Lakes. It has been covered by a sheet of ice since late January,
and usually freezes rapidly because it is quick to cool.
Lake Ontario, a deep, relatively southern lake, almost never freezes. It is mostly open water, except for an ice-covered patch in its northeast corner, according to satellite images. In Lake Michigan, the only one of the Great Lakes entirely in the United States, the northern third is covered with ice.
Most of the ice is 40 centimetres to 60 centimetres thick, though some places on Lake Huron and Lake Superior have ice about 70 centimetres thick. Mr. Dicaire said the ice is so extensive he expects it will take until the end of April for spring temperatures to thaw the lake surfaces.
The ice has created havoc for shipping and ferry companies. The St. Lawrence Seaway is to open on March 25, but it is not certain that conditions in the lakes will co-operate. "We've informally talked with coast-guard people and the seaway people, and it's quite likely that that may be delayed a few days due to ice conditions," said John Falkingham, chief of forecasting operations for the Canadian Ice Service.
John Misener, a retired Great Lakes ship captain who spent decades
on the lakes, said he has taken freighters through late-season ice, and
the experience was not enjoyable for the crew or good for the vessel. "The
ice damages the ships to a certain extent. It's tough to get through
It's far better to wait for two or three weeks and see if the thing reduces
itself with a good rain."
On the East Coast, Mr. Falkingham said ferry service between Sydney, N.S., and Port aux Basques, Nfld., has been experiencing difficulty because of the thick ice. A ferry spent part of Sunday caught in ice about 38 kilometres off north Sydney and had to be helped by an icebreaker. But Mr. Falkingham said the thicker ice will be good for seals, mammals that require firm ice to give birth and to nurse their pups until they can swim. Last year, the Gulf of St. Lawrence had so little ice that many pups drowned after their mothers were forced to give birth in open water.
The ice in Eastern Canada is due to temperatures that have been below normal since January, with hardly a hint of the warming trend that is normal for this time of year. On Monday, the forecast highs in Southern Ontario were about -11, compared to an average for early March of 3. And last week, the mercury dipped to -25 in Toronto, the coldest March day in much of Southern Ontario in more than a century. "We had never seen a colder day in March since 1868. That is really phenomenal," said David Phillips, Environment Canada's authority on weather trends.
The other unusual weather this winter has been the lack of rain and
snow. According to Mr. Phillips, the entire Great Lakes-St. Lawrence region
from Windsor to Quebec City has had the lowest precipitation on record.
He said the colder temperatures have masked what would otherwise be recognized
as a severe drought.
Nonetheless, the winter has been tailor-made for those who enjoy ice, with lengthy periods where the temperatures have not exceeded 0. Even Toronto, a city with frequent winter thaws, has had 63 days in which temperatures failed to rise above 0, more than double the number last year, according to Mr. Phillips.

The Kyoto Protocol marked the beginning of a new era. Up until the end of the 80s, fear of the Soviets had provided the glue which held the Atlantic Alliance together. But Ronald Reagan’s triumph over Soviet Socialism sowed the seeds from which has sprouted the era of cross-Atlantic competition.
The new Battle of the Giants is an intra-Alliance struggle for world economic domination; no talk of ‘science’ here. This undeclared war is Transatlantic, and its protagonists are the EU and the US. The Kyoto Protocol would, when ratified by both protagonists, have begun a slow-but-sure process of weakening the US economy relative to that of the EU – and hence, have begun the (long) process of transferring world economic leadership to the Europeans.
There would have been serious collateral damage, of course, particularly to the economies of Canada and Australia. But there also would have been some spectacular winners, particularly Russia and some other FSU states.
But since the zenith of its achievement, at Kyoto in 1997, the prospect of EU world economic domination has begun to recede. The EU is a rising star on the way down.
The first giant blow to the EU was Al Gore’s narrow loss in the 2000 election, even though he played the Greenhouse Card to the hilt during his campaign. If Gore had won, the battle would have been over before it really began. But, although George W Bush showed early signs of recognizing the threat posed to the US economy by ratification of the Protocol, how long could he have held out? He had a bare majority (if any) of votes cast in 2000; he did not control the Senate; and he had no legitimate mandate to oppose Kyoto.
Enter stage left: Osama bin Laden. His 9/11/2001 horror was the second giant blow. As a consequence, the Bush Republicans swept the mid-term election in 2002 on the subsequent wave of nationalism - it was the best mid-term result for an incumbent since 1908.
In 2002, George W went out and fought for his candidates; and this time,
the voters clearly endorsed him. The Republicans now hold both houses;
and W appears unlikely to emulate his father’s inability to achieve a second

Like-minded Australian sites are www.webace.com.au/~wsh and the comprehensive www.john-daly.com.
Crucially also, the US has acquired a much-needed new friend outside the EU. Osama and the Chechens have combined to give Russia common cause with the US, where none existed previously. Bush and Putin are an item now - because of 9/11. I suspect both would be relaxed if Kyoto proceeded with Russia in, and US out. Instead of the US competing for Russian ‘hot air’, the EU (and Japan) can have it all.
Of course, things change quickly in politics. But my guess is that W feels electorally secure at present. If so, he will continue to ignore the urgings of the New York Times and Washington Post, his own science-bureaucrat advisers, the World’s Nobel Laureates and Academies of Science, France and Germany, and even his good friend Tony Blair. It is Osama who has conferred on W the stature he needed to not ratify the Kyoto Protocol.
On current knowledge, there is little chance of US ratification before the 2008 election.
I hope I am wrong here, but it looks as though the Protocol’s longer-term future (2008-12, and beyond) will evolve largely in response to economic and political factors, not because its flawed science has caused IPCC to recant.
The EU has conned its voters on how painless Kyoto will be, to the point where it now has little option but to proceed as if 9/11 never happened. Therefore, it will be the EU whose economy slowly weakens, not the US as intended. In particular, the prime sufferer now will be Germany - with Russia (selling both natural gas and carbon credits) remaining the chief beneficiary. How long can this charade last? Either a future US president will bring the US into the Protocol (or more likely, into some face-saving and ineffectual successor to it), or EU voters will ultimately wake up to their politicians and bureaucrats. I hope for the latter outcome.
I doubt if Osama would have wished it so, but if Kyoto does indeed fail, he may in effect save the lives of many unbelievers during future wintry extremes in the Northern Hemisphere – when the Sun don’t shine, and the wind don’t blow – by his help in keeping carbon-based energy available and affordable. The watershed for the Protocol’s fortunes was 9/11.
Finally, Kyoto is supposed to be about protecting the environment. But CO2 emissions are not ‘dirty’ or ‘polluting’ - as we are told ad nauseam - but a vital promoter of both biodiversity and food production. Commercial growers even add CO2 to the atmosphere of their greenhouses. In fact, the greenhouse issue is already diverting money and attention from the World’s real environmental imperatives.
The Kyoto Protocol is not about science, and it is not about the environment
– if it is averted, we will have to thank the new team – George W Bush and
Osama bin Laden.
"Global Warming" and the Australian Drought
Over the last few months many media stories have made dubious claims that the Australian drought is the "worst ever" or "worst in a hundred years". From what I can see of long term rainfall trends many media claims do not stand up to scrutiny and most data I have checked tells me that this drought is just another cyclic El Nino related drought, similar to many Australia has experienced as witnessed by our ~150 year data record. When 2002 rainfall data is to hand then we will see how the year compares to past droughts at places where we have high quality long term data. The Murray Darling Basin stream inflows for 2002 have been less than any year since the 1982'83 drought according to the Govt. website www.mdbc.gov.au
Towards the end of 2002 dubious media claims got worse by linking the drought with "Global Warming".
In January 2003 we have the World Wildlife Foundation (WWF) sponsoring a paper, "GLOBAL WARMING CONTRIBUTES TO AUSTRALIA'S WORST DROUGHT", available from the WWF as a pdf file download. It was also featured on ABC TV 7.30 Report.
The salient point relied on by the authors is that March to November maximum
temperatures (=daytime) increased sharply in the 2002 in the Murray-Darling
Basin, see here their Figure 2 with the spectacular temperature spike.
The authors should know that "Global Warming" is expressed as annual mean temperature changes and trends, not as a function of "March to November daytime temperatures". In our rebuttal of these silly WWF claims we first look at the official IPCC "global warming trends", temperature anomaly data by Jones et for two 5 degree by 5 degree grid boxes the western one on left covers most of the Murray-Darling Basin while that on the right is to the east and includes Sydney with the excessive urban heat island data contamination there (see my cities pages for the Sydney story). While the IPCC is telling us that the MDB has been cooling over 120 years, it seems a little strained to make this connection between "Global Warming" and the 2002 drought.

Coolwire has tried to keep readers up to date with progress
in the Castles / Henderson critique of IPCC modeling scenarios. Now
the "The Economist" has weighed in to say "... the IPCC had better check its

From The Economist print edition
The Intergovernmental Panel on Climate Change had better check its calculations
AT THE beginning of 2001 the Intergovernmental Panel on Climate Change (IPCC) released, as the main result of its massive Third Assessment Review, a set of figures that have become the most-cited numbers in the field of environmental policy, and quite possibly the most-cited numbers in any field of public policy. The panel, whose task was to assess the extent to which emissions of greenhouse gases may warm the planet over the coming century, reported that “globally averaged mean surface temperature is projected to increase by 1.4 to 5.8°C over the period 1990 to 2100.” This alarming conclusion has become the starting-point for popular and official discussion of global warming and the policies that might mitigate it. Bear in mind how expensive some approaches to the problem, such as the Kyoto Protocol, might be if governments actually succeeded in implementing them. Vast sums are at stake.
As a rule, the IPCC is careful to attach warnings to its projections. Journalists are impatient with that: they prefer “prediction” to “projection” (less vague) and like to talk of temperature rising by “as much as 5.8°” rather than quoting the full range. This is all very misleading—but the panel cannot be blamed for the way its work is reported. What it can be blamed for is the seriously flawed methods it has followed in making its estimates.
n recent months, two distinguished commentators—Ian Castles of the National Centre for Development Studies at Australian National University, formerly the head of Australia's national office of statistics; and David Henderson of the Westminster Business School, formerly the chief economist of the OECD—have put together a critique of the panel's Special Report on Emissions Scenarios (SRES). The report claims to “provide the basis for future assessment of climate change”, but Mr Castles and Mr Henderson point to serious flaws in its analysis and results. Last year they began writing to the chairman of the panel. Following an invitation to a technical meeting convened by the IPCC last month, they have offered further comments. The critique which thus evolved is to be published next month*.
One key problem with the IPCC's report, sufficient by itself for Mr Castles and Mr Henderson to declare the document “technically unsound”, is the way the scenario-builders have based their projections of future output on national GDP estimates which have been converted to a common measure using market exchange rates. This procedure leads them to overstate the initial gaps in average incomes between rich and poor countries—because prices tend to be much lower in poor countries. Those gaps are in turn crucial for the IPCC's projections, because the method used in the scenarios assumes not only that the rich countries will continue to get richer but also, in most of the 40 scenarios considered, that the greater part of the (overstated) initial gaps between rich and poor will be closed by the end of the century.
of overstated gaps and of built-in assumptions about the extent of convergence
in the average incomes of rich and poor countries yields projections of GDP
for developing regions which are improbably high. Even the scenarios which
give the lowest figures for projected cumulative emissions in the course
of the century assume that average incomes in the developing countries as
a whole will increase at a much faster rate than has ever been achieved in
Miracles and anomaliesThe unreality of the assumptions about economic growth in developing countries is highlighted by disaggregated projections which were recently released on the SRES website. These projections imply that, even for the lowest emission scenarios, the average income of South Africans will have overtaken that of Americans by a very wide margin by the end of the century. In fact America's per capita income will then have been surpassed not only by South Africa's, but also by that of other emerging economic powerhouses, including Algeria, Argentina, Libya, Turkey and North Korea.
The SRES summary for policymakers tells anxious governments that the 40 scenarios “together encompass the current range of uncertainties of future emissions”. Plainly, this is incorrect. The panel's low-emissions scenarios make exceptionally optimistic assumptions about economic growth in the developing world. But it is impossible to say, without running the whole exercise afresh, what the properly calculated range of projections for temperature changes would be.
Mr Castles and Mr Henderson offer a variety of other criticisms of the SRES, and of the panel's treatment of economic issues more generally. They complain, for instance, that history is too much neglected in the consideration of future trends. They also point out that developments in the first ten years of the scenario period, 1990-2000, were pretty clear by the time the SRES was published in 2000, and that in some respects they diverged substantially from the scenarios' projections; yet the report pays them little or no heed. Mr Castles and Mr Henderson argue that the circle of those involved in the climate-change exercise has been too restricted. For the future, the panel should draw on a wider range of economic and statistical interests and expertise. In particular, where its member governments are concerned, there needs to be a greater involvement of economic ministries and statistical agencies, alongside environment ministries.
The full panel meets next week in Paris to review the preparation of its Fourth Assessment Review. It should take the opportunity to consider the Castles-Henderson critique and resolve to do something about it.
