    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/.

Thunderstorm Safety

Thunderstorms can be really dangerous! Flash floods, lightning bolts, hail, tornadoes...all of these things can hurt you if you're not careful. So here's some safety tips.

GO INSIDE! If you hear distant thunder or see a flash of light, get indoors immediately. Seek shelter from sturdy buildings, not lean-tos or outhouses. You can stay in a car if that is your only option, but do not touch any of the metal on the car. If you cannot find shelter, stay away from tall, isolated objects such as trees, poles, or posts. Make sure that you are not the tallest object by crouching down. Crouch down, bend forward, and grab your ankles. Keep your head down. Do not lie flat on the ground and try to keep out of puddles or other standing water.

If you can get into a house or school, go down to either the basement or a room that is in the center of the building. Stay away from windows. That way, if a tornado touches down, you'll be safe.

Do not use a phone or a computer during a thunderstorm. Do not take a shower or wash dishes. Lightning can strike the plumbing or electrical wires that connect to your house and give you an electrical shock if you use these items.

After the storm passes, wait about half an hour before leaving the house. Lightning can still be prevalent in the sky, and more storms may come. If there are downed power lines anywhere around you, DO NOT touch them. Call your electrical company and have them take care of it.
