Arguments against global warming hardly based on fact
Is a new ice age on the way despite evidence of global warming? Interestingly enough, we may have been on the verge of a new ice age, until it was averted by recent warming. So, a little climate change was not a bad thing, but the current data and the projections indicate that we are about to seriously overdo it. Some people dispute the warming. Is this position based on the facts?
Graphs and articles (mainly from the Internet) have been distributed claiming that historical data shows no warming in recent history, and that present annual temperatures are lower than in the past. I was sent some such graphs recently, and recognized the graphs as being plots of Greenland ice core isotope data used to reconstruct annual average temperatures during the last 50,000 years. Anyone can download this climate data from NOAA (U.S. National Oceanic and Atmospheric Administration). It appears that some have, and then severely misinterpreted it.
When I graphed the data myself, I realized that what the climate change denier author of the “cooling” graph was using as “recent” data ended in the 1800s! This is because ice slowly accumulates from snow. Data of this kind gives the values for 95 years before a “zero” year, and the zero year may be 1950, or another starting point. Recent data (not dependent on ice cores) is collected at weather stations such as at Angmagssalik, Greenland. This weather station shows the same pattern of recent, rapid warming since the 1970s that is found in other weather station records.
