In my Dec. 30, 2015, letter, I submitted a 1922 AP article stating that the Arctic zone was experiencing temperatures so warm that ice was melting and seals were leaving. Steve Lyons charged that the report represented only a selective area and time.
I agree. But that is exactly what current climate change alarmists use. Lyons notes that to have a correct picture, data must come from the largest time-and-space scales possible. Again, I agree. Unfortunately, climate change alarmists refuse to use evidence showing that ice ages (with glaciers well over one mile thick and covering large parts of the current U.S.) have alternated with warm periods for eons. That dating does not suit their purposes. And they certainly don't announce that when ice is melting in one area, it's usually increasing in another.
The National Oceanic and Atmospheric Administration (NOAA) recently released data showing that 2015 was the second hottest U.S. year on record (since 1895). Does that mean we have global warming? No.
First, the data was for the U.S., not for the globe. Second, parking lots and buildings have increased temperatures at many of our previously-rural-field weather stations. Researchers found that some data adjusted to compensate for that problem shows up to 50 percent warmer than the raw data!
NASA's satellite temperature record for the world shows a definite leveling of temperatures for the past decade or two. Also, NOAA and IPCC (Intergovernmental Panel on Climate Change) data show no increasing trends for hurricanes, tornadoes, droughts, or floods.
In recent testimony, NASA award-winning scientist John Christy compared the IPCC projections to actual data from four weather-balloon and two satellite datasets. He found that IPCC models have predicted more than twice as much warming as has actually occurred.
Again, computer models are only as good as the data inputted and cannot account for nature's compensating/balancing actions.
