Having read George C. Kaulbach’s letter of Nov. 15, I thought some real data would help him and others understand global changes. NASA has been measuring sea level using satellites. From 1994 through 2012, sea levels have risen over 2 and a quarter inches, not 1 or 2 inches over the last 100 years. A chart can be found here.

The rate of increase is a constant and sharply define rise. Kaulbach mentions global temperatures. He’s right. From 1880 to 2010, the world has warmed 1.4 degrees Fahrenheit. That doesn’t seem alarming until we look at the increase from 1975 to 2010. That is over 9/10th of one degree. The change is less than half a degree in 95 years then 9/10ths of a degree in 35 years. That should be considered amazing.

I can’t calculate the thermal mass of our planet or the amount of heat it would take to warm all the oceans and land surfaces 1 degree. It would be a lot of calories. These numbers can be found at NASA and NOAA. If we visit the U.S. Geological Survey’s information on CO2 released by volcanic eruptions to human CO2 releases from the use of carbon fuel, we learn that it would take 3,500 Mount. St. Helens to equal annual carbon fuel releases.

We do need scientific data and unemotional evaluation of global climate change. One degree in 35 years is a massive amount of heat; 3,500 annual eruptions of Mount St. Helens would be world changing. Animal flatus only comes into the debate when the facts need to be blown out of the room.
