Climate Change: Not every scientist is part of Al Gore's mythical "consensus." Scientists worried about a new ice age seek funding to better observe something bigger than your SUV — the sun.
Back in 1991, before Al Gore first shouted that the Earth was in the balance, the Danish Meteorological Institute released a study using data that went back centuries that showed that global temperatures closely tracked solar cycles.
To many, those data were convincing. Now, Canadian scientists are seeking additional funding for more and better "eyes" with which to observe our sun, which has a bigger impact on Earth's climate than all the tailpipes and smokestacks on our planet combined.
And they're worried about global cooling, not warming.
Kenneth Tapping, a solar researcher and project director for Canada's National Research Council, is among those looking at the sun for evidence of an increase in sunspot activity.
Solar activity fluctuates in an 11-year cycle. But so far in this cycle, the sun has been disturbingly quiet. The lack of increased activity could signal the beginning of what is known as a Maunder Minimum, an event which occurs every couple of centuries and can last as long as a century.
