The 1987 international agreement phased out the industrial production of chlorofluorocarbons (CFCs): chlorine - containing chemicals that help trigger the destruction of stratospheric ozone, which screens out cancer - causing ultraviolet light.
At a hearing before the House of Representatives Science Committee last week, John Doolittle, a Republican from California, said that research implicating CFCs in the destruction of ozone is «very much open to debate», and there is «no established consensus» on the role of CFCs.
The concentration of pollutants such as chlorofluorocarbons (CFCs) represents one key factor in ozone destruction, but weather conditions impact the hole as well.
«On Earth, ozone destruction by refrigerator CFCs is the cause of the polar ozone hole.
It's formula is C21H27FO6, making it a hydrofluorocarbon — a category of compounds perhaps best known for replacing chlorofluorocarbons (CFCs) when their role in the destruction of the ozone layer was discovered.
The chemical balance in the stratosphere is changed significantly by the presence of these clouds, altering the breakdown products from manmade CFCs (chlorofluorocarbons) so that rapid chemical ozone destruction can occur in the presence of sunlight.
«If left unregulated, rocket launches by the year 2050 could result in more ozone destruction than was ever realized by CFCs.»
The chemical balance in the stratosphere is changed significantly by the presence of these clouds, altering the breakdown products from manmade CFCs (chlorofluorocarbons) so that rapid chemical ozone destruction can occur in the presence of sunlight.
In the upper stratosphere (beyond the protection of the ozone layer), ultraviolet light caused CFCs to break apart, releasing chlorine, a very reactive atom that repeatedly catalyzes ozone destruction.
It is a template for how ozone destruction by human produced Chlorofluorocarbons (CFC) was a test run for the deception that human CO2 is causing global warming.
The destruction of ozone by CFC compounds requires cold conditions because at these temperatures acidic gases (hydrochloric and sulphuric acid) condense to form ice crystals and surface chemistry reactions with CFCs occur liberating the ozone destroying halogen radicals.
Requires the EPA Administrator to promulgate regulations establishing a program for the issuance of offset credits that: (1) ensure that such offset credits represent verifiable and additional GHG emission reductions or avoidance, or increases in sequestration; (2) ensure that offset credits issued for sequestration offset projects are only issued for GHG reductions that are permanent; and (3) include as reductions in GHGs reductions achieved through the destruction of methane and chlorofluorocarbons (CFCs) or other ozone depleting substances.
LOL yes, the world urgently needs Reagan - style conservatives who appreciate climate - change / CO2 science as wisely and foresightedly as Ronald Reagan appreciated ozone - destruction / CFC science!
Effectively she appears to at least confirm the possibility of my proposition that what is going on is an entirely natural solar induced process (destruction of ozone in the upper atmosphere by more incoming solar protons) which casts doubt on all previous assumptions concerning human CO2 AND CFCs.
CFC destruction of ozone caused the stratosphere to cool 1.4 C and the earth to warm some 0.5 C. Should be back to normal by 2100.
Zaelke and the team at IGSD will continue to focus on maximizing the climate - change mitigation potential of the ozone treaty through the destruction of CFCs and HCFCs contained in old air conditioners and other equipment.
And the ban on CFCs has gone a long way to repairing the destruction of stratospheric ozone, so this new research doesn't suggest that phasing out CFCs was wrong or ill - informed.
Since then we learned among other things that UV varies considerably, Polar Stratospheric Clouds (PSC) affect ozone destruction, there is no empirical evidence that CFCs were destroying ozone.
