Is the Earth’s ozone layer on the rebound? That’s what this recent article from the CSMonitor claims. In a time when “Global Warming Fever” has captured the world, is this is a little dose of hope to counter the hype? (Hey, I kind of like that. GWF! Does that have a copyright yet? Is John Travolta available for the part of a disco dancing Al Gore?) Anyway, let’s take a look at what this article has to say:
“It’s clear that the Montreal Protocol has reduced the total amount of chlorine entering the atmosphere,” notes Derek Cunnold, an atmospheric scientist at Georgia Institute of Technology in Atlanta and a member of one of the two research teams. Those reductions, he continues, should first arrest the decline, then allow the ozone layer to rebuild. “We are now seeing that kind of a response,” he says, referring to the stabilization of ozone levels.
The researchers still caution that ozone layers are extremely low, and that harmful ultraviolet rays are reaching the Earth in record quantities. Still though, in just a short time, it seems that humans have been able to at least slow a potentially devasting environmental trend. Yeah! Hurrah for humans!
