    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/.

The Scientific Process

Being a scientist is fun. You get to do experiments and think of reasons why things might be happening a certain way. Being a scientist is also hard work.

After a scientist comes up with a reason why something might be happening, they have to test that reason with experiments. If their reason holds up during experiments, then the scientist usually shares his/her findings with other scientists. In modern science, this is done by talking about the findings during a presentation or by writing about the findings in a journal. A scientific journal is like a magazine, read by other scientists. See Science for an example of a scientific journal.

A discovery isn't really accepted in the science community until other scientists agree that the first scientist's work makes sense. Sometimes agreement on a science topic takes a long time--years, or even decades. Evolution, the Big Bang, and climate change are all theories that were first brought up long ago, and these are all still being researched and worked on by scientists today.

Now it's not just scientists that do science - students do too! When you do a science experiment in class, or in a science fair project, you are taking part in the scientific process too!
