    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.

    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 ocean and diving has always been a part of my life! Since a young age, I loved and had a fascination with the natural world. My father was an admiral for the Venezuelan navy, so our family spent summers and every possible holiday in La Orchila, a Caribbean island that serves as a Venezuelan naval base that even has a pink sanded beach!

I spent every summer there for 18 years, and that free interaction with nature became my microscope and telescope to see and learn about our planet and space. We would swim freely aside all kinds of fish and watch turtles nest, and I even had a crab collection. It's what got me fascinated with nature and science and the wonders of the ocean. Ramon Llaneza, is my brother in law and a renown diving instructor. I met Ramon at age 18 and he diving instructor for Scuba Diving and I got most of my knowledge from his teachings. I am a IANTD & CMAS certified diver.

Now I live in Boulder, Colorado at the foothills of the Rocky Mountains and I am fond to hiking and skiing in Colorado, but every year, once a year, I join my family in Florida and together with my nieces and nephew I enjoy trips and keep learning and admiring the underwater and wonder of this magic world!
