    Irish Chronicles Document Links Between Volcanoes and Weather

    A study of over 40,000 written entries in Irish Annals and ice core measurements shows a strong correlation between the occurrence of volcanic eruptions and extreme cold weather in Ireland over a 1200 year period. Data analyzed in this study cover the period from 431 to 1649, during which time up to 48 volcanic eruptions are identified in Greenland ice core records through deposition of volcanic sulfate in annual layers of ice. You can find the study (open access), published on 6 June 2013 in IOP Publishing's journal Environmental Research Letters, at http://iopscience.iop.org/1748-9326/8/2/024035/article.

    EF-5 Tornado in El Reno, Oklahoma Widest Ever Recorded in US

    The EF-5 tornado that hit El Reno, Oklahoma on May 31st was the widest ever recorded in the US, according to the National Weather Service in Norman Oklahoma. The tornado, which remained on the ground for 40 minutes and reached 2.6 miles across (4.2 km), took the lives of 18 people including storm chasers Tim Samaras, Paul Samaras and Carl Young.

    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

Mysterious Giant Squid Found on Tasmanian Beach
News story originally written on July 29, 2002

People do not often see giant squid, which live in the deep ocean. In fact, less than 50 giant squid have ever been seen. So when a giant squid was found dead on a beach in Hobart, Tasmania, Australia last week, it was a reason for excitement!

As the name implies, the squid are very large! The giant squid that was found in Tasmania is 50 feet long, and giant squid have been found that are up to 60 feet long. They have larger eyeballs than any other animal. Each eyeball is about 18 inches across which is larger than a person's head.

Giant squid live by themselves in the deep ocean, typically far away from land. They are Mollusks and are most closely related to other Mollusks such as smaller squid and octopus. All squid, even the small ones, are carnivores and hunt their prey, but only giant squid can hunt prey as large as whales.

The giant squid that washed up on the beach may be a new species, say scientists at the Tasmanian Museum and Art Gallery. The squid was taken to the museum, where scientists noticed large flaps of muscle around its legs, a characteristic never seen before. "It's basically like having a pile of muscles on your own body that nobody else has," said David Pemberton, chief curator at the museum.

The scientists at the museum will conduct research on the body of the giant squid and then they will put it on display at the museum for people to see.
