From the It’s the sun, stupid Department. Michael Mann to tweet #KochMachine in 3, 2, 1…
According to Professor Lockwood the late 20th century was a period when the sun was unusually active and a so called ‘grand maximum’ occurred around 1985. Since then the sun has been getting quieter.
By looking back at certain isotopes in ice cores, he has been able to determine how active the sun has been over thousands of years.
Following analysis of the data, Professor Lockwood believes solar activity is now falling more rapidly than at any time in the last 10,000 years.
He found 24 different occasions in the last 10,000 years when the sun was in exactly the same state as it is now – and the present decline is faster than any of those 24.
Based on his findings he’s raised the risk of a new Maunder minimum from less than 10% just a few years ago to 25-30%.
And a repeat of the Dalton solar minimum which occurred in the early 1800s, which also had its fair share of cold winters and poor summers, is, according to him, ‘more likely than not’ to happen.
He believes that we are already beginning to see a change in our climate – witness the colder winters and poor summers of recent years – and that over the next few decades there could be a slide to a new Maunder minimum.
But don’t worry, warming from CO2 will save the alarmists’ careers:
Any global cooling caused by this natural phenomenon would ultimately be temporary, and if projections are correct, the long term warming caused by carbon dioxide and other greenhouse gases would eventually swamp this solar-driven cooling.
