Mauna Loa

Posted by Picasa

I think this is Mauna Loa. The new snowfall can be seen on the top of the mountain. The observatory on Mauna Loa is the site where carbon dioxide measurements have been made on a continual basis, hourly, for the last 51 years.These measurements show the cycling of CO2 in the atmosphere in direct relationship to the seasons. In the winter when the trees are bare of leaves in the Northern hemisphere, the concentration of CO2 goes up. In the summer, the concentration in the air goes down. In the 50 years of measurements the concentration rose from 315ppm to 385ppm.
Could a global warming trend be the cause of our especially wet and cold fall and winter? Well, maybe.Warmer temperatures do produce more snow.
