    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/.

Easter Island

Easter Island, also known as Rapa Nui, is a volcanic island located in the Southeast Pacific Ocean. It was given the name "Easter Island" when a Dutch explorer visited the island on Easter Sunday in 1722.

Easter Island is located far from other islands or continents. Chile is 3,600 km (2,237 miles) to the east and Tahiti is 3,200 km (2,000 miles) to the west. This small island is shaped like a triangle. There is an extinct volcano at each corner. Craters in the volcanoes contain water, and the rest of the island is covered by grasslands and ancient lava flows. Easter Island has a subtropical climate.

Easter Island is well-known because of the 887 large stone statues created by the Rapa Nui people. They created these statues, called moai, as a way to worship their ancestors. In the 1500s the Rapa Nui people began to create petroglyphs of the bird-man cult. The Rapa Nui population dropped because of warfare on the island, slave raids from the mainland of South America, and exposure to European diseases. Approximately 2,300 Rapa Nui people live on Easter Island today.

People visit Easter Island to view the moai. The moai are now part of a national park and have been designated a World Heritage Site by UNESCO.
