GLOBAL WARMING PROVEN NATURAL NOT MAN-MADE ONCE AGAIN
[It is quite gratifying that TTP’s “Solar Warming” published ten years ago continues to be proven correct –JW]
Most global warming is natural and even if there had been no Industrial Revolution current global temperatures would be almost exactly the same as they are now, a study has found.
The paper, by Australian scientists John Abbot and Jennifer Marohasy, published in GeoResJ uses the latest big data technique to analyze six 2,000 year-long proxy temperature series from different geographic regions.
“Proxies” are the markers scientists use – tree rings, sediments, pollen, etc – to try assess global temperature trends in the days before the existence of thermometers.
All the evidence suggests that the planet was about a degree warmer during the Medieval Warming Period than it is now; and that there is nothing unnatural or unprecedented about late 20th century and early 21st century “climate change”.
