Even today, "there is some degree of uncertainty about natural pga tour variability," acknowledged Mark McCaffrey, programs and policy director of the National Center for Science pga tour Education based in Oakland, Calif. "If it weren't for the fact that humans had become a force of nature, we would be slipping back into an ice age, according to orbital pga tour cycles."
But pga tour earth's glacial pga tour rhythms are "being overridden by human activities, especially burning fossil fuels," McCaffrey noted. The stories about global pga tour cooling "are convenient for people to trot out and wave around," he said, but they miss the point: 
"What's clear is we are a force of nature. Human activity – the burning of fossil fuels and land change – is having a massive influence. We are in the midst of this giant geoengineering experiment."
