Volcano produced lightning


We normally associate lightning being caused by severe thunderstorms, however, thought you might like seeing lightning caused by volcanic eruptions. This photo is from the Eyjafjallajökull volcano in Iceland. Click on the following link to see more images from this on-going volcanic eruption.

Winter wheat emerges from its winter sleep in Nebraska



Spring is finally here! April 16, 2010 in Central Nebraska with a green landscape from the Winter wheat crop rapidly beginning to grow. Winter wheat is planted from September to October in Nebraska. Winter wheat sprouts before freezing occurs, then becomes dormant until the soil warms in the spring. It is harvested in Nebraska in late June and July and is very vulnerable to the peak season for hail in Nebraska which is also late June and July. North Dakota and the Prairie Provinces of Canada, however, plant "Spring Wheat" in May and harvest it in the Autumn.

March 2010 global temperatures were the warmest since records began in 1880.

Here is an animation that I created of all the monthly global temperature anomaly maps from September 2005 through March 2010:

Wednesday, April 14, 2010


With 116 years of climate data, it was an amazing January 1-March 31, 2010 time period. New England was the warmest ever recorded for this time period and the Great Lakes had much above normal temperatures. However, Florida experienced it coldest ever first three months of the year, and much of the Gulf region was much below normal. Nebraska? Right in the middle of it all, Nebraska’s temperatures averaged near normal for the first three months of the year.
