CLIMATOLOGY: THE MODERN ASTROLOGY THAT CAN EXPLAIN EVERYTHING

Take your pick below

(1) GLOBAL WARMING MAKES NORTH ATLANTIC LESS SALTY

Since the late 1960s, much of the North Atlantic Ocean has become less salty, in part due to increases in fresh water runoff induced by global warming, scientists say. Now for the first time researchers have quantified this fresh water influx, allowing them to predict the long-term effects on a "conveyor belt" of ocean currents. Climate changes in the Northern Hemisphere have melted glaciers and brought more rain, dumping more fresh water into the oceans, according to the analysis. One of the expected high-profile consequences is a rising sea that will swamp coastal communities....

(2) GLOBAL WARMING MAKES NORTH ATLANTIC MORE SALTY

The surface waters of the North Atlantic are getting saltier, suggests a new study of records spanning over 50 years. And this might actually be good news for the effects of climate change on global ocean currents in the short-term, say the study's researchers. This is because saltier waters in the upper levels of the North Atlantic ocean may mean that the global ocean conveyor belt -- the vital piece of planetary plumbing which some scientists fear may slow down because of global warming -- will remain stable. The global ocean conveyor belt is the crucial circulation of ocean waters around the Earth. It helps drive the Gulf Stream and keeps Europe warm. The density of waters which drives the flow of ocean currents is dependent on temperature and salinity, so any change in saltiness may have an impact.

Tim Boyer of the US National Oceanographic Data Center and colleagues compiled salinity data gathered by fisheries, navy and research ships travelling across the North Atlantic between 1955 and 2006. They found that during this time, the layer of water that makes up the top 400 metres has gradually become saltier. The seawater is probably becoming saltier due to global warming, Boyer says. "We know that upper ocean is warming in the North Atlantic, so it stands to reason that there should be more evaporation, making waters more salty," he says.

TAMING THE HURRICANE: AN ANTIDOTE TO CLIMATE ALARMISM

On September 28, 1955, a Category 5 hurricane named Janet slammed into Chetumal, on Mexico's Yucatan Peninsula, killing over 600 people. Hurricane Dean, another Category 5, and the third-strongest storm ever measured at landfall, hit in exactly the same place earlier this week (Tuesday, August 21,2007) and killed no one. Maximum winds in both storms were indistinguishable. The hurricane-hunter pilot who flew through the eyewall of the storm Tuesday reported severe turbulence, which is a temporary loss of aircraft control.

Probably for the first time in human history, a Category 5 storm hit a populated area and everyone lived. Because of its peculiar location, the Yucatan takes more big hurricane hits than just about anywhere else in the western hemisphere. When Mexico was dirt-poor, as it was in 1955, hurricanes could kill hundreds. They were warned, then, too. Hurricane-hunter planes also monitored Janet. Only one of these has ever been lost, and it as Janet was making landfall. Similar storms, huge storms, very different results. What's happening here?

Since then, people in the Yucatan have learned to adapt. While storms like these used to kill hundreds, even thousands, we now have the technology to forecast their tracks, at least for the critical last 24 hours, with reasonable confidence. Forecasting the intensity is a bit trickier, but everyone in the hurricane business was pretty convinced that Dean was going to bomb out sometime before it hit land.

After all, it was passing over the same region in which 1988 hurricane Gilbert set the record for the lowest barometric pressure ever measured in the Atlantic Basin. Gilbert was the second-strongest storm ever recorded at landfall, and also hit the Yucatan. While it was responsible for 202 deaths in Mexico, almost all of these were caused by mountain floods hundreds of miles away and days away from landfall.

Adaptation includes technology, infrastructure, and response. National Hurricane Center forecasts and data are available to everyone. But the infrastructure to respond to a forecast hurricane costs money, and poor nations don't have it. Among other things, it requires good roads for evacuation. Perhaps even more important, adaptation to hurricanes or other natural disasters is political. No elected official wants to be blamed for hundreds of preventable deaths, so the nations that can afford it develop evacuation plans, open shelters, and deliver people from danger.

When Janet killed hundreds, per-capita income in Mexico was less than a tenth of what it is now, when Dean killed no one. So why is it that people are wringing their hands about global warming causing more severe hurricanes and deaths? The best computer estimate for future hurricanes was published by Tom Knutson and Robert Tuleya in the Journal of Climate in 2004. They calculated that maximum winds should increase by about 6% over the next 75 years. Even this may be an overestimate because the method used assumes carbon dioxide "the main global warming emission" is increasing in the atmosphere about twice as fast as it actually is.

Clearly, this small increase in hurricane strength is going to be dramatically overshadowed by adaptation as the developing world continues to develop. Mexico is a case in point. We see other adaptations to climate change in our cities. In the United States, cities with the most frequent heat waves have the fewest heat-related deaths, and heat-related deaths are themselves dropping, as our cities warm. Remember, a city doesn't need global warming to get hot. All it needs is a skyline, and a lot of blacktop and concrete to impede the flow of air and retain heat. But in our warming cities, just as with hurricanes in the Yucatan, frequency + affluence = adaptation.

An odd example of this is that there is only one major U.S. city in which heat related deaths are increasing, and it is the coolest one in summer: Seattle. Anyone concerned about climate change should take a lesson from Hurricane Dean. Even if storms like this become more frequent in the future, people will adapt and survive if they have the financial resources. How silly it seems to take those resources away in futile attempts to "stop global warming" which no one even knows how to do when they could save lives by allowing people to adapt to our ever-changing climate. The truth is that money in the hand is a lot more useful than treaties on paper when it comes to sparing yourself and your family from bad weather. So people truly worried about climate change should be cheerleading for the global trade and economic development that will continue allowing us to adapt.

UN DREAMING: MOST CO2 EMISSION CUTS HAVE TO COME FROM DEVELOPING COUNTRIES

More than two thirds of cuts in greenhouse gas emissions needed by 2030 to fight climate change will have to come from developing countries, the United Nation's climate change secretariat said on Thursday. By 2030 the world will need to spend hundreds of billions of dollars annually to fight climate change, said the report on an "appropriate international response to climate change". "It's not just a question of throwing more money at the problem," the U.N.'s climate change chief, Yvo de Boer, told Reuters. "(It's) incredibly important to put in place policies and measures that guide those investments in the right direction." The report said emissions have to drop in the next 25 years to 2004 levels. Some 68 percent of emissions cuts must take place in developing countries, it added.

GREENHOUSE WARMING: WRONG ALTITUDE AND LATITUDE DEPENDENCE?



Figure 1: Predicted greenhouse warming (left) versus reality (right) as a function of latitude (x) and altitude (y)

Lord Monckton has written down a convincing paper showing that the greenhouse effect predicts a "hot spot" at certain rather high altitudes above the equatorial zones, something that isn't really observed:

This point was emphasized to me by Fred Singer half a year ago. Thanks to Robert Ferguson who also offers a text explaining that consensus is rubbish.

THE LOGIC OF GLOBAL WARMING JIHADISTS

In every child's life there comes a time when childhood fantasies are shattered and he or she is forced to accept reality - there is no Santa Claus or tooth fairy; parents don't always mean it when they promise to stay married until parted by death. Grown-up scientists, theologians, historians, archaeologists and others who pursue facts and objective truths are rooted in reality and constantly adjusting their conclusions, theories and hypotheses when new information comes to light. Those who ignore facts and cling to outdated information, or outright falsehoods, can quickly embrace fanaticism.

So it is with "global warming," the secular religion of our day that even has a good number of adherents among people of faith. Having decided to focus less on the eternal and whether anyone dwells there, global warming fundamentalists are pushing planet worship on us in a manner that would make a jihadist proud. There are at least two characteristics all fundamentalists share. One is the exclusion and sometimes suppression of any and all information that challenges or contradicts the belief one wishes to impose on all. The other is the use of the state in pursuit of their objectives, overriding the majority's will.

With global warming, some members of the scientific community - not all of whom are climatologists, who disagree among themselves - have circled the wagons, denying access and labeling illegitimate any scientist who disagrees with the 'doctrines' of a recently warming planet. The big media have been complicit in this censorship or ridicule of alternative views, mostly refusing to interview anyone who does not push the global warming faith.

CBS News this week broadcast a four-part series on ''climate change.'' Newsweek magazine recently slammed global warming ''deniers.'' That brought a counterattack in the Aug. 20 issue from Newsweek contributor Robert Samuelson, who termed the article ''highly contrived'' and ''fundamentally misleading.'' In 1975, Newsweek was just as convinced - using ''scientific evidence'' - that a new ice age was upon us.

Many global warming fanatics have pointed to NASA as proof that their concerns about a warming planet are justified. They have repeatedly cited the Goddard Institute for Space Studies (GISS), whose director, James Hansen, has asserted that nine of the 10 warmest years in history have occurred since 1995, with 1998 the warmest. When NASA was confronted with evidence provided by Climate Audit, a blog run by Stephen McIntyre devoted to auditing the statistical methods and data used in historical reconstructions of past climate data, it reversed itself. Without the fanfare used to hype the global warming fanaticism it had earlier supported, NASA now says four of the top 10 years of high temperatures are from the 1930s. Several previously selected ''warm'' years - 2000, 2002, 2003 and 2004 - fell behind 1900.

GISS now says its previous claim that 1998 was the warmest year in American history is no longer valid. The warmest year was 1934. Has any of this new information changed the minds of the global warming fundamentalists? Nope. Neither has much of it seen the light of day in the mainstream media, which continue to carry stories where seldom is heard an alternative word and the skies are polluted all day.

The New York Times ran a story in its Sunday Business section last week that said it would cost a lot of money to fight global warming. The implication being that this money should come from government (and taxpayers), along with more government regulations and control over our lives by the very people who seem to have difficulty winning wars and controlling spending.

The Earth has warmed and cooled over many centuries. One can get a sense of who is telling the truth about global warming by the company the concept keeps. Most of the disciples of global warming are liberal Democrats who never have enough of our money and believe there are never enough regulations concerning the way we lead our lives. That ought to be enough to give everyone pause, along with emerging evidence that the global warming jihadists may be more full of hot air than the climate they claim is about to burn us up.

***************************************

The Lockwood paper was designed to rebut Durkin's "Great Global Warming Swindle" film. It is a rather confused paper -- acknowleging yet failing to account fully for the damping effect of the oceans, for instance -- but it is nonetheless valuable to climate atheists. The concession from a Greenie source that fluctuations in the output of the sun have driven climate change for all but the last 20 years (See the first sentence of the paper) really is invaluable. And the basic fact presented in the paper -- that solar output has in general been on the downturn in recent years -- is also amusing to see. Surely even a crazed Greenie mind must see that the sun's influence has not stopped and that reduced solar output will soon start COOLING the earth! Unprecedented July 2007 cold weather throughout the Southern hemisphere might even be the first sign that the cooling is happening. And the fact that warming plateaued in 1998 is also a good sign that we are moving into a cooling phase. As is so often the case, the Greenies have got the danger exactly backwards. See my post of 7.14.07 and a very detailed critique here for more on the Lockwood paper
