Ozone depletion is greatest in polar regions during the winter, explaining why the greatest warming observed from to was of minimum temperatures in polar regions, a phenomenon known as polar amplification. Scientists suddenly realized that ozone depletion was a much bigger problem than had been thought. Within two years, scientists and political leaders developed the Montreal Protocol on Substances that Deplete the Ozone Layer mandating cutbacks in CFC production beginning January By , increases of CFCs in the atmosphere stopped.
By , increases in ozone depletion stopped. By , increases in average global temperatures stopped. The ozone layer remains depleted, the ocean continues to warm, ice continues to melt, and sea-level continues to rise, but global temperatures did not change significantly from through They also had not changed much from to Thus, humans appear to have accidently caused the warming starting around by manufacturing large amounts of CFCs and to have accidently stopped the warming of air in while trying to limit ozone depletion.
Meanwhile, atmospheric concentrations of carbon dioxide rose linearly, but at ever-increasing rates, showing no direct relationship to the details of observed global warming. Dozens of peer-reviewed scientific papers by leading atmospheric scientists have tried to explain, based on greenhouse-warming theory, why global temperatures did not change much from through , a phenomenon dubbed the global warming hiatus.
While they suggest many interesting ideas, there has been little agreement. These types of lava flows, covering tens to millions of square miles , have been contemporaneous with periods of greatest global warming, ocean acidification, and mass extinctions throughout all of geologic time. For example, million years ago, the Siberian basalts covered an area of 2. Basalts emit prodigious amounts of chlorine and bromine that seem to cause ozone depletion, although the precise chemical path has yet to be deciphered.
In the s, many leading scientists were convinced that greenhouse gases were the cause of global warming, that Earth was in danger of overheating during the 21 st century as emissions of greenhouse gases increase, and that scientists must demonstrate consensus in order to convince political leaders to take the expensive steps necessary to reduce greenhouse-gas emissions.
The IPCC has involved thousands of climate scientists writing tens of thousands of pages of thoughtful science supporting greenhouse-warming theory. The IPCC never did question the widespread assumption, however, that greenhouse gases were the primary cause of global warming. In December , this effort reached fruition with the Paris Agreement where leaders of nearly all countries agreed to work together to reduce greenhouse-gas emissions.
Science, however, is not done by popular vote. Science is not done by consensus. Consensus is the stuff of politics; debate is the stuff of science. Science is never settled. As Michael Crichton put it at Caltech in What is relevant is reproducible results. The greatest scientists in history are great precisely because they broke with the consensus. There is no such thing as consensus science.
If it's consensus, it isn't science. If it's science, it isn't consensus. IPCC scientists are so convinced by their consensus and so tired of arguing with climate skeptics, that they refuse to even think about ozone depletion. Their models calculate that greenhouse gases absorb a lot more terrestrial infrared radiation than the small amount of solar ultraviolet-B radiation reaching Earth when ozone is depleted. Yet what they fail to realize is that the energy in thermal radiation is not a function of amount; it is a function of frequency.
Ultraviolet-B radiation has 48 times the frequency of infrared radiation absorbed most strongly by carbon dioxide, 48 times the energy—has the potential to make the temperature of the absorbing body 48 times hotter. Ultraviolet-B radiation has enough energy to cause sunburn, skin cancer, and cataracts, something no amount of infrared energy can do. After all, you get much warmer standing in sunlight than standing outside at night with terrestrial infrared radiation welling up around you.
I can now show that greenhouse gases do not absorb enough heat to be the primary cause of observed global warming. It is not that difficult to google acid rain and global warming and ozone depletion Then you can take pride in doing your own homework.

Global warming vs Ozone depletion? What is the difference between ozone depletion and global warming? Difference between global warming, climate change, greenhouse effect, and ozone depletion? Answer Questions Is it just me or is my neighbour having a rant at me? How many yachts sailed through the North West Passage this year?
So, Earth survived with much more CO2 than it has now. When naval bases are flooded, what will global warming deniers blame for the flooding? Would a planet with an atmosphere as thick as that of Venus be hot because of pressure? Or cold because of Rayleigh scattering?
Scientists have determined that the thinning ozone layer is caused largely by propellants and pollution by a class of chemicals called CFC’s. Many countries around the world have joined together to ban the use of those chemicals. Global Warming. Global warming is a much more controversial problem.
Ozone Depletion and Global Warming How the video was a good example of a persuasive speech? The video was a good example of a persuasive essay because of its overall structure from attention-getter and visual aid to the conclusion and performance.
Global Warming refers to the increase in the average temperature of earth. The Greenhouse Effect is the role that the atmosphere plays in insulating and warming earth's surface. Ozone depletion is the vanishing of our ozone layer, which protects earth from harmful UV rays. global warming - Stratospheric ozone depletion - Since the s the loss of ozone (O3) from the stratosphere has led to a small amount of negative radiative forcing of the surface. This negative forcing represents a competition between two distinct effects caused by .
