Excellence in wingnut science!
Today's winner: Powerline's John Hinderaker for posting this cute little picture:

And then linking to this site from which he quotes:You don’t hear much about the ozone hole any more. Has it gone away? Nope. NOAA and NASA say in 2006 it was bigger and deeper than ever.There are two startlingly easy concepts John will never comprehend:
But wait, you say, we implemented the Montreal Protocols in 1989, eliminating ozone depleting CFCs. Kofi Annan called the Protocol, “Perhaps the most successful international agreement to date.” CFC concentrations have been falling since 1995. How can the ozone hole be worse?
It’s not worse, says NOAA, it’s better. It’s just that you can’t see how great the Protocol is working because colder than average temperatures in the Antarctic mask the benefit. Cold weather “result[s] in larger and deeper ozone holes, while warmer weather leads to smaller ones.”
Colder in Antarctica? Al Gore told me it was melting! Al Gore told me there was consensus. Consensus!
1.) The ozone layer is expected to take 50 years to recover "when the atmospheric amounts of reactive chlorine and bromine return to their pre-ozone-hole levels."
2.) Decreased stratospheric temperatures are partially due to increased greenhouse gas emissions:
Although increasing greenhouse gas concentrations in the atmosphere may result in warmer surface temperatures, colder temperatures are expected to occur in the stratosphere. In fact, temperatures in the lower stratosphere, as measured by NOAA's Microwave Sounding Unit, have cooled during the past 22-years, the length of the satellite record. Colder stratospheric temperatures can enhance ozone loss through their affect on the formation of polar stratospheric clouds which in turn promote chlorine-caused ozone destruction.The stupid! It burns!
