Australian geophysicist, astronautical engineer and NASA astronaut Phil Chapman has a slightly terrifying column in the Australian cautioning the world to focus on the real climate crisis–the next ice age. There have been rumblings (muted of course by the much louder global warming voices) the last several years of a coming ice age, based mainly on the slow yet steady decline in earth’s tempurature during the past decade. Chapman, however, examines another indicator of temperature trends–a delay in sunspot cycles.
The sunspot number follows a cycle of somewhat variable length, averaging 11 years. The most recent minimum was in March last year. The new cycle, No.24, was supposed to start soon after that, with a gradual build-up in sunspot numbers.
It didn’t happen. The first sunspot appeared in January this year and lasted only two days. A tiny spot appeared last Monday but vanished within 24 hours. Another little spot appeared this Monday. Pray that there will be many more, and soon.
The reason this matters is that 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.
Northern winters became ferocious: in particular, the rout of Napoleon’s Grand Army during the retreat from Moscow in 1812 was at least partly due to the lack of sunspots.
That the rapid temperature decline in 2007 coincided with the failure of cycle No.24 to begin on schedule is not proof of a causal connection but it is cause for concern.
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.
