A persistent school of thought in recent years has held that so-called "chevrons," large U- or V-shaped formations found in some of the world's coastal areas, are evidence of megatsunamis caused by asteroids or comets slamming into the ocean.
University of Washington geologist and tsunami expert Jody Bourgeois has a simple response: Nonsense.
The term "chevron" was introduced to describe large dunes shaped something like the stripes you might see on a soldier's uniform that are hundreds of meters to a kilometer in size and were originally found in Egypt and the Bahamas.

Acid-rain countermeasures could drown London
New research from NASA suggests that the Arctic warming trend seen in recent decades has indeed resulted from human activities: but not, as is widely assumed at present, those leading to carbon dioxide emissions. Rather, Arctic warming has been caused in large part by laws introduced to improve air quality and fight acid rain.

The death toll from days of heavy rain in Kansas rose to five Wednesday when authorities found the bodies of two people in a car submerged in a flooded creek.
A 26-year-old Parsons man and a 22-year-old Springfield, Mo., woman were found by Labette County sheriff's deputies in Pumpkin Creek in southeast Kansas, the state Division of Emergency Management said.
The couple had been reported missing Tuesday evening. Authorities believe they were traveling west on a road and were swept into the creek at a low-water crossing.

This is a news story from Germany outlining another Arctic ice measurement expedition. This one was conducted by flying the scientists across the north polar ice cap using the WWII era workhorse Douglas DC-3 airplane equipped with skis, and towing an airborne sounder twenty meters above the ice surface. It makes the Catlin Arctic Ice Survey look rather pointless, but then we knew that. BTW "Eisdicken" translates to "ice thickness". - Anthony

Long-term variations in ocean circulations produce pronounced patterns of sea surface temperature (SST) anomalies that directly impact weather and climate. The most influential long-term oceanic cycle is the Pacific Decadal Oscillation (PDO), a large-scale phenomenon in the North Pacific that produces inter-decadal oscillations of cool and warm SST anomalies, with each phase typically lasting 20 to 30 years. During the cool (negative) phase of the PDO, a large horseshoe-shaped area of cooler than average SST extends from the central equatorial tropics northeastward to the Mexican and U.S. coastlines, then northward along the Canadian and Alaskan coastlines. During the warm (positive) phase the pattern is reversed with warm SSTs replacing the cool SSTs. The Atlantic Ocean experiences a similar oscillation known as the Atlantic Multidecadal Oscillation (AMO) which has profound impacts on the number and intensity of Atlantic hurricanes as well as Arctic sea ice extent.

Michigan affiliate's chief meteorologist slams disingenuousness of MSNBC's 'Future Earth' special; GE's financial stake in cap-and-trade passage.
NBC Universal and its networks have been criticized for the global warming alarmism it parades on a regular basis. However, now the criticism is coming from its own affiliates.
Prior to its April 26 airing on MSNBC, shows on NBC had been promoting the first part of the climate special "Future Earth" - an MSNBC program that used computer animation to show the possibilities of a polar icecap melting. That prompted Bill Steffen, a meteorologist for NBC's Grand Rapids, Michigan affiliate, to call out MSNBC for that special.

Charlotte Pass, 1,837m, Snowy Mountains of New South Wales, Australia
A new Australian record was set early this morning, a temperature of minus 13 degrees, at Charlotte Pass on the Snowy Mountains.
This is the lowest temperature recorded anywhere in Australia in April and is 13 below the average. Nearby at Perisher it dipped to minus 11 degrees and at the top of Thredbo it dipped to minus 10.
Across the border, on the Victorian Alps April records were broken at Mt Hotham where it chilled to minus eight degrees and Mt Buller and Falls Creek where it got as low as minus seven.

Abandoned mines in the Wayne are well-known among biologists as winter havens for hibernating bats. Banning visitors could help keep white-nose syndrome from extending into Ohio, officials say. Discovered in New York in 2006, the disease has spread to eight other Eastern states, including Pennsylvania and West Virginia. The syndrome is named for a white fungus that grows on bats' faces, ears, wings and feet.
Nearly 500,000 bats have died.
For the first time, Japan has been hit with a large-scale collapse of honeybee populations like that experienced in other countries around the world.
"There have been small-scale honeybee losses for many years, but a massive collapse like they had in the U.S. is very unusual," said Kiyoshi Kimura of the National Institute of Livestock and Grassland Science. "We must investigate the situation in Japan."

Shiveluch is one of the largest and most active Kamchatka volcanoes. It belongs to the Kliuchevskaya volcano group and is about 65,000 years old. Shiveluch is erupting during the last year being observated by Volcano logy Institute of Kamchatka. Volcano consists of two cones called Maliy and Bolshoy Shiveluch. Maliy Shiveluch is erupting now. The mountain grows constantly because of volcanic materials rising from the depths throughout crater.
Comment: The only problem with this debunking theory is that the chevrons in Madagascar are made of material from the ocean floor with sediment hundreds of meters deep and containing microfossils that are fused with metals typically formed by cosmic impacts.
Chevrons in Madagascar
Unless sea level has changed drastically in 5,000 years this "counter theory" (which is not a theory at all since it's not explaining what has caused these chevrons) is far more worthless than the theory it's trying to replace.
