The Montreal Protocol Excuse

Filed under: Mockery,Montreal Excuse,Morons,The Pause — sunshinehours1 @ 5:18 AM

I hear there is a new explanation for The Pause in global warming. The new excuse is that a drop in CFC’s (which are a type of GHG)  has saved us!

“Our statistical analysis suggests that the reduction in the emissions of ozone-depleting substances under the Montreal Protocol, as well as a reduction in methane emissions, contributed to the lower rate of warming since the 1990s.”

The World Meteorlogical Organization puts out a Greenhouse Gas Bulletin.  Lets take a quick look at a couple of the claims.

1. “reduction in methane emissions”

Not really. One or two are down. Some have paused. Others are up.

As the WMO says “Sulfur hexafluoride (SF6) is a potent LLGHG. It is produced by the chemical industry, mainly as an electrical insulator in power distribution equipment. Its current mole fraction is about twice the level observed in the mid-1990s (Figure 6). The stratospheric ozone-depleting chlorofluorocarbons (CFCs), together with minor halogenated gases, contribute ~12%[4] to radiative forcing by LLGHGs. While CFCs and most halons are decreasing, hydrochlorofluorocarbons (HCFCs) and hydrofluorocarbons (HFCs), which are also potent greenhouse gases, are increasing at relatively rapid rates, although they are still low in abundance”

2. “reduction in the emissions of ozone-depleting substances”

Not really! There was a CH4 pause but it resumed rising in 2006.

3. What about N2O which contributes 6% of the radiative forcing? Nope.

Lets take a look at the over all table. I see no reduction. (I also don’t see H2O, but the AGW Cult always ignores water vapor).
