    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/.

Haumea - Hawaiian Goddess

Haumea was the goddess of childbirth and fertility in Hawaiian mythology. Her children included the volcano and fire goddess Pele, the sea goddess Namaka, and Hi'iaka - the patron goddess of hula dancers.

In one Hawaiian myth, Haumea's children were born by springing forth from various parts of the body of their mother. Hi'iaka sprang from Haumea's mouth, while Namaka came from her mother's thigh.

Haumea is also the name astronomers have given to a dwarf planet in our Solar System. The dwarf planet's moons bear the names of two of Haumea's children, Hi'iaka and Namaka.

There are several connections between the myth of Haumea and the dwarf planet and its moons. Astronomers think Haumea may have collided with another large object a long time ago. It is possible that debris from this collision coalesced to form Haumea's moons. If so, the scientific story matches the myth, as the "children" (moons) of Haumea did indeed "spring forth from" the "body" of their "mother" (the dwarf planet).

The goddess Haumea also represents the "element" of stone. The dwarf planet Haumea appears to contain more rocky material than is the case for most Kuiper Belt Objects, which are often richer in ice. Thus the dwarf planet mimics its namesake in this regard as well.

Finally, one of the groups involved with the discovery of the dwarf planet used telescopes in Hawaii to observe this faint, distant object. It is therefore quite appropriate that Haumea bears a name from Hawaiian mythology!
