Scientists speak, so it must be true:
Earth could be entering a new Ice Age within the next millennium, but it might not, the deep freeze averted by warming from increased carbon dioxide emissions. Humans could be thwarting the next glacial inception, a new study says.
Even in the comparatively long time scales of Earth history, we're kind of overdue for another ice age — our current Holocene era has lasted about 11,600 years, roughly 600 years longer than the average interglacial (between-ice-age) periods of the past. If atmospheric CO2 levels were lower, the next ice age might have started sometime within the next 1,000 years, according to researchers from University College London and Cambridge University.
Of course, we could accept this as just one hypothesis and keep looking for other evidence, always ready to adjust our theories as better evidence becomes available, but why start now?
