The Australian April 23
It is time to put aside the global warming dogma, at least to begin contingency planning about what to do if we are moving into another little ice age, similar to the one that lasted from 1100 to 1850.
Sunspot activity has not resumed up after hitting an 11-year low in March last year, raising fears that — far from warming — the globe is about to return to an Ice Age, says an Australian-American scientist.
All those urging action to curb global warming need to take off the blinkers and give some thought to what we should do if we are facing global cooling instead.
Physicist Phil Chapman said the world cooled quickly between January last year and January this year, by about 0.7 degrees Centigrade. This is the fastest temperature change in the instrumental record, and it puts us back to where we were in 1930," "If the temperature does not soon recover, we will have to conclude that global warming is over."
All four agencies that track Earth's temperature (the Hadley Climate Research Unit in Britain, the NASA Goddard Institute for Space Studies in New York, the Christy group at the University of Alabama, and Remote Sensing Systems Inc in California) report that it cooled by about 0.7C in 2007. This is the fastest temperature change in the instrumental record and it puts us back where we were in 1930.
there is a close correlation between variations in the sunspot cycle and Earth's climate. The previous time a cycle was delayed like this was in the Dalton Minimum, an especially cold period that lasted several decades from 1790.
