    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/.

Prehistoric Fossil Snake is Largest on Record
News story originally written on February 4, 2009

Scientists discovered the fossils of a gigantic snake. It lived in South America 60 million years ago. It was longer than a school bus and weighed 1140 kilograms (2500 pounds). This snake was a constrictor, which means it would wrap its huge body around its prey before eating.

Scientists discovered the fossils of the snake in a coal mine in northern Colombia. They also looked for clues in the rocks to learn what the environment where the snake lived was like. They discovered that it was a tropical rainforest.

The tropical rainforests that were in South America 60 million years ago were very different than the rainforests that are there today. It was hotter then. Plus, the reptiles that lived there, like the snake, were much larger.

Places with warmer temperatures tend to be home for larger cold-blooded animals. This means that when Earth’s climate is warmer, the cold-blooded animals are larger. The scientists say that this fossil snake’s size means that the temperature was five degrees Celsius warmer than today’s tropical rainforests.
