Could CFCs cause Global Warming?

Answer 1

CFC's and other halocarbons contribute to Global Warming, but their contribution amounts to less than a third of the contribution of CO2. This is important, but at least we have a handle on CFCs' thanks to the Montreal Protocol, so their influence should gradually wane over time.

But CO2 is growing exponentially with no end in sight. That's why the emphasis is on CO2, as it should be.

Answer 2

Chlorofluorocarbons (CFC) are haloalkanes with both chlorine and fluorine. They were formerly used widely in industry, for example as refrigerants, propellants, and cleaning solvents. Their use has been regularly prohibited by the Montreal Protocol, because of effects on the ozone layer (see ozone depletion). They also contribute to global warming. They have a global warming potential (GWP), in terms of carbon dioxide equivalence (over a time period of one hundred years) between 6000 and 9800 per kg.[citation needed]

Hydrochlorofluorocarbons (HCFCs) are of a class of haloalkanes where not all hydrogen has been replaced by chlorine or fluorine. They are used primarily as chlorofluorocarbon (CFC) substitutes, as the ozone depleting effects are only about 10% of the CFCs

Answer 3

They're a small part of it. That's the "ozone" line on this graph of verified and peer reviewed data.

And getting smaller all the time as the ozone layer recovers, thanks to am international treaty called the Montreal Protocol. We need a treaty like that for global warming, Kyoto isn't working.

By the way, I can't believe anyone is still recommending the "swindle" movie, which has been thoroughly refuted.

It is simply a political statement which distorts science.

"The science might be bunkum, the research discredited. But all that counts for Channel 4 is generating controversy."

Gore's movie may be a little over dramatic, but it has the basic science right. This movie does not.

Channel 4 itself undercuts the movie in a funny way. If you go to their website on the movie you find links to real global warming information. They also say "Confused now? Ask the Expert." The link for questions goes to a respected mainstream scientist who supports (mostly) human responsibility for global warming.

No one with any knowledge about global warming believes it.

Answer 4

CFCs add to the effect of greenhouse gases. The ozone layer reduces the amount of UV radiation that reaches the Earth by absorbing UV radiation. CFCs react with ozone and reduce the thickness of the ozone layer. Any reduction in this layer causes the Earth to receive more energy from the sun. High-intensity UV radiation also kills marine phytoplankton and destroys photosynthetic cells in plants, which leads to lower amounts of CO2 removal from the atmosphere by plants.

Answer 5

No CFC are a refrigerant why would that do any thing ??

Answer 6

no

join the heresy
