Calif. —Dungeness and rock crabs caught off the California coast should not be eaten because of dangerous levels of domoic acid, a naturally occurring toxin.
There has been little use of domoic acid throughout history except for in Japan, where it has been used as an anthelmintic for centuries. Domoic acid was first isolated in 1959 from a species of red algae, Chondria armata, in Japan; commonly referred to as “doumoi” (in Tokunoshima's dialect word) or “hanayanagi”. Poisonings in history have been rare, or undocumented; however, it is thought that the increase in human activities is resulting in an increasing frequency of toxic algal blooms along coastlines in recent years. Consequently, poisonings have been affecting sea animals, birds, and humans.
Test results recently showed that it wasn’t domoic acid (amnesic shellfish poisoning) that caused the whales’ death. At the end of August, Wynne expects results of two other tests — one for the toxin that causes PSP and one for Cesium 137 radionuclide, which is produced in nuclear reactors like the one that suffered damage after Japan’s 2011 earthquake.
Seattle Times, Jun 15, 2015: Toxic algae bloom might be largest ever — Scientists onboard a NOAA research vessel are beginning a survey of what could be the largest toxic algae bloom ever recorded off the West Coast… At the same time, two other types of toxins rarely seen in combination are turning up,,, along the Washington coast… the toxin has never hit so hard in the spring, or required such widespread closures for crabs… concentrations in California anchovies this year [are] as high as any ever measured…
The Pacific Decadal Oscillation (PDO) is often described as a long-lived El Niño-like pattern of Pacific climate variability (Zhang et al. 1997). As seen with the better-known El Niño/Southern Oscillation (ENSO), extremes in the PDO pattern are marked by widespread variations in the Pacific Basin and the North American climate. In parallel with the ENSO phenomenon, the extreme phases of the PDO have been classified as being either warm or cool, as defined by ocean temperature anomalies in the northeast and tropical Pacific Ocean.

Personally If I where Putin I would assassinate Erdogan. Problem solved.

The Russian Ambassedor to France has said that the Russians are not averse to being part of a "Joint Command" - including France and the US - that will help coordinate their efforts against ISIS.
If they were going to do anything, they would have done it by now. They would not have allowed the international community to ease the tension. Besides, the Turks don't have any support. Even American sources are questioning whether or not the plane was in Turkish airspace when it was brought down.
