GLOBAL COOLING NOW!

Big chill hits Queensland, Australia. (Queensland is about the size of California and Texas combined)

BONE-chilling winds of up to 75km/h have blasted through southeast Queensland, bringing down trees, powerlines and even a brick wall. The southwesterly winds saw Brisbane record its lowest June temperature on record. A maximum of 13.1C was recorded at the airport but the wind chill factor dragged this down to only 5.6C.

At a Fortitude Valley construction site, a freestanding wall collapsed on to a neighbouring unit block at about 5am, hammering the roof with up to 80 concrete bricks. Builder Ivano Berlese said it was a "freak of nature". "It really must have come through here hard, because the wheelie bins were all blown over and there was a power line down in another street," he said. Five people were evacuated from the top floor of the building at about 5:30am and allowed back in briefly a few hours later, to pick up some belongings.

The wind was also blamed for halting train services on the Cleveland line, after blowing debris on to overhead wires. Queensland Rail said buses were organised to transport passengers between Lindum and Cleveland, during the morning peak. Fallen trees and branches also caused disruption to traffic and power supply. More than 4000 homes and businesses were blacked out across southeast Queensland throughout the day.

The Lockyer Valley, Gatton, Dayboro and the Sunshine Coast fared the worst. Brisbane escaped relatively unscathed from blackouts. The cold snap pushed southeast Queensland electricity usage to its highest this winter as people turned on power-hungry reverse cycle airconditioners and heaters.

Weather bureau statistician Ann Farrell said the previous June record for the airport was 13.9C in 1958 and the coldest overall was 10.6C in August 1954. Toowoomba was worse off, recording a wind chill temperature of -9.3C overnight, with parts of the Darling Downs reporting a blast of early morning sleet and snow. At noon it had risen to -3.8C. All of the Downs and Granite Belt reported extremely cold conditions, with Warwick 1C at 2pm and Applethorpe -1.2C, thanks again to the wind. Overnight Brisbane dipped down to -2.5C, allowing for the wind factor.

Ms Farrell said overcast conditions had caused the temperature to be about 5C lower than predicted. "Once cloud cover comes over and it combines with cold air, the temperatures won't go up," she said. Better conditions are predicted for today although it will remain cold, with clear skies. Moreton Bay was no place to be with gusts recorded to 76km/h at the Inner Beacon, about halfway between the mainland and Moreton Island.

Read the sunspots

The heading on the post above was satirical. This post is not: The mud at the bottom of B.C. fjords reveals that solar output drives climate change - and that we should prepare now for dangerous global cooling

By R. TIMOTHY PATTERSON. R. Timothy Patterson is professor and director of the Ottawa-Carleton Geoscience Centre, Department of Earth Sciences, Carleton University, Canada

Politicians and environmentalists these days convey the impression that climate-change research is an exceptionally dull field with little left to discover. We are assured by everyone from David Suzuki to Al Gore to Prime Minister Stephen Harper that "the science is settled." At the recent G8 summit, German Chancellor Angela Merkel even attempted to convince world leaders to play God by restricting carbon-dioxide emissions to a level that would magically limit the rise in world temperatures to 2C.

The fact that science is many years away from properly understanding global climate doesn't seem to bother our leaders at all. Inviting testimony only from those who don't question political orthodoxy on the issue, parliamentarians are charging ahead with the impossible and expensive goal of "stopping global climate change." Liberal MP Ralph Goodale's June 11 House of Commons assertion that Parliament should have "a real good discussion about the potential for carbon capture and sequestration in dealing with carbon dioxide, which has tremendous potential for improving the climate, not only here in Canada but around the world," would be humorous were he, and even the current government, not deadly serious about devoting vast resources to this hopeless crusade.

Climate stability has never been a feature of planet Earth. The only constant about climate is change; it changes continually and, at times, quite rapidly. Many times in the past, temperatures were far higher than today, and occasionally, temperatures were colder. As recently as 6,000 years ago, it was about 3C warmer than now. Ten thousand years ago, while the world was coming out of the thousand-year-long "Younger Dryas" cold episode, temperatures rose as much as 6C in a decade -- 100 times faster than the past century's 0.6C warming that has so upset environmentalists.

Climate-change research is now literally exploding with new findings. Since the 1997 Kyoto Protocol, the field has had more research than in all previous years combined and the discoveries are completely shattering the myths. For example, I and the first-class scientists I work with are consistently finding excellent correlations between the regular fluctuations in the brightness of the sun and earthly climate. This is not surprising. The sun and the stars are the ultimate source of all energy on the planet.

My interest in the current climate-change debate was triggered in 1998, when I was funded by a Natural Sciences and Engineering Research Council strategic project grant to determine if there were regular cycles in West Coast fish productivity. As a result of wide swings in the populations of anchovies, herring and other commercially important West Coast fish stock, fisheries managers were having a very difficult time establishing appropriate fishing quotas. One season there would be abundant stock and broad harvesting would be acceptable; the very next year the fisheries would collapse. No one really knew why or how to predict the future health of this crucially important resource.

Although climate was suspected to play a significant role in marine productivity, only since the beginning of the 20th century have accurate fishing and temperature records been kept in this region of the northeast Pacific. We needed indicators of fish productivity over thousands of years to see whether there were recurring cycles in populations and what phenomena may be driving the changes.

My research team began to collect and analyze core samples from the bottom of deep Western Canadian fjords. The regions in which we chose to conduct our research, Effingham Inlet on the West Coast of Vancouver Island, and in 2001, sounds in the Belize-Seymour Inlet complex on the mainland coast of British Columbia, were perfect for this sort of work. The topography of these fjords is such that they contain deep basins that are subject to little water transfer from the open ocean and so water near the bottom is relatively stagnant and very low in oxygen content. As a consequence, the floors of these basins are mostly lifeless and sediment layers build up year after year, undisturbed over millennia.

Using various coring technologies, we have been able to collect more than 5,000 years' worth of mud in these basins, with the oldest layers coming from a depth of about 11 metres below the fjord floor. Clearly visible in our mud cores are annual changes that record the different seasons: corresponding to the cool, rainy winter seasons, we see dark layers composed mostly of dirt washed into the fjord from the land; in the warm summer months we see abundant fossilized fish scales and diatoms (the most common form of phytoplankton, or single-celled ocean plants) that have fallen to the fjord floor from nutrient-rich surface waters. In years when warm summers dominated climate in the region, we clearly see far thicker layers of diatoms and fish scales than we do in cooler years. Ours is one of the highest-quality climate records available anywhere today and in it we see obvious confirmation that natural climate change can be dramatic. For example, in the middle of a 62-year slice of the record at about 4,400 years ago, there was a shift in climate in only a couple of seasons from warm, dry and sunny conditions to one that was mostly cold and rainy for several decades.

Using computers to conduct what is referred to as a "time series analysis" on the colouration and thickness of the annual layers, we have discovered repeated cycles in marine productivity in this, a region larger than Europe. Specifically, we find a very strong and consistent 11-year cycle throughout the whole record in the sediments and diatom remains. This correlates closely to the well-known 11-year "Schwabe" sunspot cycle, during which the output of the sun varies by about 0.1%. Sunspots, violent storms on the surface of the sun, have the effect of increasing solar output, so, by counting the spots visible on the surface of our star, we have an indirect measure of its varying brightness. Such records have been kept for many centuries and match very well with the changes in marine productivity we are observing.

In the sediment, diatom and fish-scale records, we also see longer period cycles, all correlating closely with other well-known regular solar variations. In particular, we see marine productivity cycles that match well with the sun's 75-90-year "Gleissberg Cycle," the 200-500-year "Suess Cycle" and the 1,100-1,500-year "Bond Cycle." The strength of these cycles is seen to vary over time, fading in and out over the millennia. The variation in the sun's brightness over these longer cycles may be many times greater in magnitude than that measured over the short Schwabe cycle and so are seen to impact marine productivity even more significantly.

Our finding of a direct correlation between variations in the brightness of the sun and earthly climate indicators (called "proxies") is not unique. Hundreds of other studies, using proxies from tree rings in Russia's Kola Peninsula to water levels of the Nile, show exactly the same thing: The sun appears to drive climate change.

However, there was a problem. Despite this clear and repeated correlation, the measured variations in incoming solar energy were, on their own, not sufficient to cause the climate changes we have observed in our proxies. In addition, even though the sun is brighter now than at any time in the past 8,000 years, the increase in direct solar input is not calculated to be sufficient to cause the past century's modest warming on its own. There had to be an amplifier of some sort for the sun to be a primary driver of climate change.

Indeed, that is precisely what has been discovered. In a series of groundbreaking scientific papers starting in 2002, Veizer, Shaviv, Carslaw, and most recently Svensmark et al., have collectively demonstrated that as the output of the sun varies, and with it, our star's protective solar wind, varying amounts of galactic cosmic rays from deep space are able to enter our solar system and penetrate the Earth's atmosphere. These cosmic rays enhance cloud formation which, overall, has a cooling effect on the planet. When the sun's energy output is greater, not only does the Earth warm slightly due to direct solar heating, but the stronger solar wind generated during these "high sun" periods blocks many of the cosmic rays from entering our atmosphere. Cloud cover decreases and the Earth warms still more.

The opposite occurs when the sun is less bright. More cosmic rays are able to get through to Earth's atmosphere, more clouds form, and the planet cools more than would otherwise be the case due to direct solar effects alone. This is precisely what happened from the middle of the 17th century into the early 18th century, when the solar energy input to our atmosphere, as indicated by the number of sunspots, was at a minimum and the planet was stuck in the Little Ice Age. These new findings suggest that changes in the output of the sun caused the most recent climate change. By comparison, CO2 variations show little correlation with our planet's climate on long, medium and even short time scales.

In some fields the science is indeed "settled." For example, plate tectonics, once highly controversial, is now so well-established that we rarely see papers on the subject at all. But the science of global climate change is still in its infancy, with many thousands of papers published every year. In a 2003 poll conducted by German environmental researchers Dennis Bray and Hans von Storch, two-thirds of more than 530 climate scientists from 27 countries surveyed did not believe that "the current state of scientific knowledge is developed well enough to allow for a reasonable assessment of the effects of greenhouse gases." About half of those polled stated that the science of climate change was not sufficiently settled to pass the issue over to policymakers at all.

Solar scientists predict that, by 2020, the sun will be starting into its weakest Schwabe solar cycle of the past two centuries, likely leading to unusually cool conditions on Earth. Beginning to plan for adaptation to such a cool period, one which may continue well beyond one 11-year cycle, as did the Little Ice Age, should be a priority for governments. It is global cooling, not warming, that is the major climate threat to the world, especially Canada. As a country at the northern limit to agriculture in the world, it would take very little cooling to destroy much of our food crops, while a warming would only require that we adopt farming techniques practiced to the south of us.

Meantime, we need to continue research into this, the most complex field of science ever tackled, and immediately halt wasted expenditures on the King Canute-like task of "stopping climate change."

Greenies don't WANT CO2 levels reduced

Except by inflicting suffering on us, of course



A clash with the U.S. Environmental Protection Agency is threatening to scuttle a U.S. company's plan to "seed" the Pacific Ocean with iron dust to offset global warming. Planktos Inc., which has offices in Vancouver and San Francisco, wants to set sail this month from Florida to dump more than 45 tonnes of iron dust into the sea near the Galapagos Islands. The iron nutrients would stimulate the growth of phytoplankton, which would then absorb large amounts of carbon dioxide -- an experimental process Planktos compares to reforestation.

A for-profit "ecorestoration" company, Planktos plans to sell carbon credits from this and other projects to firms such as Vancouver's Wedgewood Hotel and Spa, which has agreed to buy 5,000 tonnes of carbon credits. The firm launched its "Voyage of Recovery" program in March, mustering its supplies and launching a public relations campaign in Washington, D.C., to promote its "green message of hope."

But in May, the EPA warned the firm it may need a permit under the U.S. Ocean Dumping Act if it uses its U.S.-registered vessel, the Weatherbird II. Planktos CEO Russ George says U.S. regulations should apply only when a firm dumps levels of a substance that are one per cent or more above the level considered toxic. His firm's plan would fall "roughly a billion times below regulatory limit," he said.

If the EPA stands in his way, he says he will use a flag-of-convenience ship. "There are 42,000 large vessels on the ocean in world today. We have shipping agents in Central America working for us lining up vessels that might be able to assist."

Planktos' controversial plan, which has drawn fire from environmental groups and many scientists, will be on the agenda of this week's meeting of the International Maritime Organization in Spain, which sets international shipping standards for matters such as ocean dumping.

In a submission to the group, of which both Canada and the U.S. are members, the American government urges other nations to scrutinize any such project, adding that "Planktos was not able to provide the EPA with any information ... (on) the potential environmental impacts" of the plan. In particular, the U.S. cites the possibility that the project would lead to toxic algae blooms, and that the decomposing plankton masses would release other greenhouse gases or choke off the oxygen supply in the deep ocean.

Nonsense, says Mr. George. "The world has spent the last 20 years and more than $100 million" developing the science behind the plan, he says. "These questions have all been addressed," he says, blaming the EPA's reservations on "fearmongering" by environmental groups, such as the Ottawa-based ETC Group, which discovered the U.S. government document this week. He adds that the plan would not only draw carbon dioxide out of the atmosphere, but by restoring dwindling plankton levels, it would help reverse the ongoing acidification of the ocean -- a climate-change-related process that is killing the planet's coral reefs.

Why not tie carbon taxes to actual levels of warming? Both skeptics and alarmists should expect their wishes to be answered

After much effort, G8 leaders last week agreed to "stabilize greenhouse-gas concentrations at a level that would prevent dangerous anthropogenic interference with the climate system." This is the same wording as in Article Two of the UN Framework Convention on Climate Change, signed in 1992. In other words, after months of negotiations, world leaders agreed on a text they had already ratified 15 years earlier.

Global-warming policy is stuck in a permanent stalemate for very basic reasons. Important divisions of opinion still exist on the extent of humanity's influence on climate, whether or not the situation is a crisis, whether and how much greenhouse-gas emissions should be cut, if so how to do it, and what is the most we should be prepared to pay in the process. With this stalemate in mind, I would like to propose a thought experiment about a climate policy that could, in principle, get equal support from all sides.

The approach is based on two points of expert consensus. First, most economists who have written on carbon-dioxide emissions have concluded that an emissions tax is preferable to a cap-and-trade system. The reason is that, while emission-abatement costs vary a lot, based on the target, the social damages from a tonne of carbon-dioxide emissions are roughly constant. The first ton of carbon dioxide imposes the same social cost as the last ton. In this case, it is better for policy-makers to guess the right price for emissions rather than the right cap.

Most studies that have looked at that the global cost per tonne of carbon dioxide have found it is likely to be rather low, less than US$10 per tonne. We don't know what the right emissions cap is, but, if we put a low charge on each unit of emissions, the market will find the (roughly) correct emissions cap.

Second, climate models predict that, if greenhouse gases are driving climate change, there will be a unique fingerprint in the form of a strong warming trend in the tropical troposphere, the region of the atmosphere up to 15 kilometres in altitude, over the tropics, from 20 degrees North to 20 South. The Intergovernmental Panel on Climate Change (IPCC) states that this will be an early and strong signal of anthropogenic warming. Climate changes due to solar variability or other natural factors will not yield this pattern: only sustained greenhouse warming will do it.

Temperatures in the tropical troposphere are measured every day using weather satellites. The data are analyzed by several teams, including one at the University of Alabama-Huntsville (UAH) and one at Remote Sensing Systems (RSS) in California. According to the UAH team, the mean tropical tropospheric temperature anomaly (its departure from the 1979-98 average) over the past three years is 0.18C. The corresponding ing RSS estimate is 0.29C.

Now put those two ideas together. Suppose each country implements something called the T3 tax, whose U.S. dollar rate is set equal to 20 times the three-year moving average of the RSS and UAH estimates of the mean tropical tropospheric temperature anomaly, assessed per tonne of carbon dioxide, updated annually.

Based on current data, the tax would be US$4.70 per ton, which is about the median mainstream carbon-dioxide-damage estimate from a major survey published in 2005 by economist Richard Tol. The tax would be implemented on all domestic carbon-dioxide emissions, all the revenues would be recycled into domestic income tax cuts to maintain fiscal neutrality, and there would be no cap on total emissions.

Many people would like to be kind to others so Leftists exploit that with their nonsense about equality. Most people want a clean, green environment so Greenies exploit that by inventing all sorts of far-fetched threats to the environment. But for both, the real motive is generally to promote themselves as wiser and better than everyone else, truth regardless.

Global warming has taken the place of Communism as an absurdity that "liberals" will defend to the death regardless of the evidence showing its folly. Evidence never has mattered to real Leftists

Thanks very much for promoting our NRSP Science Advisory Committee member Professor Patterson's article. I have followed his research for years, having visited his lab and even done some coring with him. I can assure you it is first class research that turned me from a Kyoto supporter into someone who now believes we should continue to work on controlling pollution better (CO2 is not pollution of course) and conserve energy but the idea that we can have a significant effect on global climate by fiddling with our CO2 emissions now seems very far fetched indeed.

I invite you to hear more from the scientists we work with at the Natural Resources Stewardship Project by visiting www.nrsp.com, especially the news page.
