Earth Changes
Basking sharks, which can grow up to 33 feet long and weigh more than a Hummer H1, spend the late spring, summer and early fall in the temperate regions of the world's oceans. But then they pull their great disappearing act, eluding scientists throughout the winter months.
Albert Einstein once said, "No amount of experimentation can ever prove me right; a single experiment can prove me wrong." Einstein's words express a foundational principle of science intoned by the logician, Karl Popper: Falsifiability. In order to verify a hypothesis there must be a test by which it can be proved false. A thousand observations may appear to verify a hypothesis, but one critical failure could result in its demise. The history of science is littered with such examples.
A hypothesis that cannot be falsified by empirical observations, is not science. The current hypothesis on anthropogenic global warming (AGW), presented by the U.N.'s Intergovernmental Panel on Climate Change (IPCC), is no exception to this principle. Indeed, it is the job of scientists to expose the weaknesses of this hypothesis as it undergoes peer review. This paper will examine one key criterion for falsification: ocean heat.
Ocean heat plays a crucial role in the AGW hypothesis, which maintains that climate change is dominated by human-added, well-mixed green house gasses (GHG). IR radiation that is absorbed and re-emitted by these gases, particularly CO2, is said to be amplified by positive feedback from clouds and water vapor. This process results in a gradual accumulation of heat throughout the climate system, which includes the atmosphere, cryosphere, biosphere, lithosphere, and, most importantly, the hydrosphere. The increase in retained heat is projected to result in rising atmospheric temperatures of 2-6ºC by the year 2100.
"We are hardwired at a genetic level to seek survival at almost any cost," says Dr. Irwin Redlener of Columbia University. Our base survival instincts will kick in as the food chain collapses, says Redlener, an expert at the National Cdnter for Disaster Preparedness. Civilization as we know it will change forever. We could see deadly competition for food, for water, and for power, as civilization collapses. (I agree.)
Although the number of ski areas around the world still open for skiing and boarding continues to diminish, heavy snow is still falling in the Alps and the Rockies, even though May is just days away. In the southern hemisphere Australian resorts have reported big pre-season snowfalls. Despite the late date in the season, www.Skinfo.com powder alarms were in double figures this week with many of the resorts that are still open in the Alps reporting falls of 30-60cm (12-24 inches).
Over half-a-metre (20 inches) of snow has been falling on Australia's ski slopes over the past 48 hours, with most still not expecting to open for nearly six weeks or more.
Snow continues to fall at Perisher in New South Wales. From the peaks to the valleys, a thick layer of snow can be found, making the resort look more like July than April. Another 25cm (10 inches) of snow settled across the upper elevations on Monday night, April 27th.
Overnight temperatures dropped to -5 degrees Celsius and it is currently 0 degrees Celsius at the bottom of the Forester Quad Express. Weather forecasters have predicted that overnight temperatures will stay nice and cool with more snow showers expected in early May. Cold temperatures will also allow Perisher to commence its snowmaking operations earlier as well.
The southern hemisphere's ski season will have one of its earliest openings on record this weekend when Mt Buller in Australia runs its lifts on Saturday, May 2nd.
The resort, in Victoria province, had not planned to open before June and the new date is five weeks ahead of schedule. It's the area's earliest opening in its 45 year history.
The opening is the result of unseasonably cold weather which brought up to 50cm (20 inches) of snow to many of Australia's ski fields (Buller has 35cm/14 inches), although currently there are no reports of any others planning to follow Mt Buller and open early.
Despite the late date in the season, www.Skinfo.com powder alarms were in double figures this week with many of the resorts that are still open in the Alps reporting falls of 30-60cm (12-24 inches).
France got the best of the snow yesterday with Tignes, Val d'Isere, Val Thorens, Argentiere and Chamonix all reporting heavy new snowfalls on Tuesday (28 April), La Grave had 20cm (eight inches) of new snow on Sunday (26 April).
Two resorts are left open in France, but both Chamonix and Tignes will close for the winter this weekend on Sunday May 10th. Then there's a month's wait until the country's three summer ski options - Tignes, Val d'Isere and Les 2 Alpes open. In the meantime the only snow skiing in France will be indoors, at the Amneville indoor slope.
The Alfred Wegener Institute is one of the six research organizations involved in the month-long expedition, called Pan-Arctic Measurements and Arctic Climate Model Inter Comparison Project. The other five include three from Canada (Environment Canada, University of Alberta, York University) one from the U.S. (National Oceanic and Atmospheric Administration) and one from Italy (Institute of Atmospheric Sciences and Climate.
