    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/.

Global Warming Endangers an Alaskan Eskimo Village
News story originally written on August 28, 2002

Global warming is raising temperatures of arctic regions much faster than other areas on Earth. This rapid warming is causing the village of Shishmaref, Alaska to wear away slowly into the sea.

Shishmaref, located on a small barrier island off the coast of Alaska, is the home of 600 Eskimo people. They have noticed over many years that winters are warmer than they used to be with less sea ice surrounding their island. In fact, the average winter temperature in Alaska is now 4 degrees Celsius higher than it was 40 years ago.

The arctic warms much faster than other places because the warming climate melts snow and ice that cover the surface, allowing the newly exposed Earth surface to absorb more solar energy. As the surface is able to absorb more energy, the climate warms some more and is able to melt even more snow and ice according to Gunter Weller, professor at the University of Alaska.

As the arctic warms, the layer of frozen ground that covers the surface melts, becoming soft and easily worn away. This means that Shishmaref's small island was once solid but is now basically a pile of shifting sand and dirt.

Without sea ice surrounding the island and frozen ground the island is exposed to severe storms, which are wearing away the coast so rapidly that people of the village are considering moving the entire town off the island.
