To state that climate change will be ‘catastrophic’ hides a cascade of value-laden assumptions which do not emerge from empirical or theoretical science,” Hulme wrote.Lindzen singled out Secretary of State John Kerry for his ‘ignorance’ on science. “Kerry expresses his ignorance of what science is,” he added.The fossil organism identified as a red algae called , found in rocks on Somerset Island and Baffin Island in Nunavut, was discovered more than two decades ago and estimated to be between 720 million and 1.2 billion years old.

Now researchers from Mc Gill University, using a relatively new radiochemical dating technique, have estimated that the fossils are between 1.03 billion and 1.06 billion years old.
The fact that they're significantly less than 1.2 billion years old will likely reassure biologists who were previously skeptical of the fossil, said Timothy Gibson, lead author of the new study published earlier in December in the journal Geology.
Some scientists' calculations based on DNA evidence suggested red algae couldn't have existed 1.2 billion years ago.
And being on the younger end of the range would have put its age as being similar to other fossils of recognizable complex organisms, making it nothing unusual.
Lindzen cautioned: “The most important thing to keep in mind is – when you ask ‘is it warming, is it cooling’, etc. “I urge you when looking at a graph, check the scales! And they are arguing over hundredths of a degree when it is uncertain in tenths of a degree,” Lindzen said.
— is that we are talking about something tiny (temperature changes) and that is the crucial point.” Lindzen also challenged the oft-repeated UN IPCC claim that most of warming over past 50 years was due to mankind. The uncertainty here is tenths of a degree,” he noted. “And the proof that the uncertainty is tenths of a degree are the adjustments that are being made.
Knowing precisely how old the fossil is also allowed the researchers to estimate that the very first plant likely evolved around 1.25 billion years ago.
Bangiomorpha, a microscopic fossil organism just fractions of a millimetre long, was first discovered beautifully preserved in layers of chert — effectively, glass — in cliffs on Somerset Island in Nunavut.
Ralph Cicerone has even admitted that there is no evidence for catastrophic claims of man-made global warming. Miike Hulme, Professor of Environmental Sciences at the University of East Anglia, and Director of the Tyndall Centre for Climate Change Research, admitting that claims of a climate catastrophe were not the “language of science.” “The discourse of catastrophe is a campaigning device,” Hulme wrote to the BBC in 2006.
