great, but that is not a result of CO2, thats the result of banning CFC's

Is this your own poll of scientists?

My point was, it's 50deg today, 01/2011. if I used the 'deniers' logic, then global warming is here. I don't use this as an argument, just making a point on the 'it snowed in December, climate change isn't real' argument

Isn't the chemical that replaced CFC's one of the leading causes of
" Global Warming" ?

Never heard that. I believe HFC's are about ten times weaker than CFC's in regards to global warming, and 50 times weaker in regards to ozone depletion.

Hey wasn't the ozone hole a big scam as well???

Worester's high of 58 today tied the all time record set in 1892.z

No other records than Salty's ranting about Barry's vacation costs were tied or broken today.

Ok now that was friggin funny

There is no such thing as global warming. It's all been dreamed up.

It's really Obama's fault.

From Wikipedia...
The interim replacements for CFCs are hydrochlorofluorocarbons (HCFCs), which deplete stratospheric ozone, but to a much lesser extent than CFCs.[10] Ultimately, hydrofluorocarbons (HFCs) will replace HCFCs with essentially no ozone destruction (although all three groups of halocarbons are powerful greenhouse gases).

I don't know if it was a scam but do you know it was not?

I don't know what you mean by a 'scam'?
Ozone was a real issue, and globally it was a significant achievement to reduce the depletion of Ozone in the atmosphere by eliminating CFC's

Note; I don't have time to dig out a text and look it up, but from memory, with the caveat that I'm not an atmospheric chemist:

HFC's are a greenhouse gas. Not as effective at trapping solar radiation as CFC's, so besides the ozone benefit of banning cfc's there is a reduction in greenhouse gas, albeit a slight one. We are essentially swapping one GHG with another, with the added benefit of not destroying the Ozone layer.

the amount of HFC's in the atmosphere vs CO2 is orders of magnitude smaller, although ideally, a non-greenhouse gas would be used as a propellant or coolant. the net benefit of HFC's over CFC's to the ozone layer is significant, even if there was no significant reduction in greenhouse gas. Think of it as the lesser of two evils.

Was a joke. People said the same thing about the ozone hole years ago, environmentalists just trying to wreck the economy, but you don't hear that today.

Then why not lobby to roll back to CFC's? They're a lot easier to make.

No Poll, just random reading over a period of time on the controversy.

I agree one day, month, year, or even a decade don't prove it either way.
I am saying to think that a massive Green Jobs Program to save the world
and produce a new economy is pie in the sky thinking.

No matter what we do China and the emerging third world countries who are
doing most of the manufacturing polution are not going to adhere to
strict standards or go to the expense.

2010 was the warmest year on record for BOS with a daily avg temp of 53.8 beating the 53.6 set in 1949 and 1953.

NWS has been recording temps in BOS since 1872
