Climate change is change I can believe in.  It changes 4 times a year around here. It gets warm, then hot, then cool and cold. It's called the 4 seasons.

The holes in the ozone layer exist above the North and South poles.
Actually those holes have closed. And they closed in a way that scientists can not explain. Maybe they really don't "know" a lot of different things but just take an educated guess, such is the nature of a theory.
The ozone layer self heals. Ozone molecules in the atmosphere are constantly being replenished created when energetic ultraviolet light splits normal oxygen. In addition, the ozone layer is replenished by upward diffusion of smog-induced surface ozone.
The belief that CFC molecules will rise and collect in the stratosphere is incorrect. Even if they did, there is a low probability of enough CFC decomposition necessary for ozone depletion. Based on Professor Rowland’s own calculations, there will be one CFC for every 136 million normal oxygen atoms in the ozone layer at 25 km altitude.
Ozone truth for duckie
I await your typical response! Name calling!
No one wants your job! You throw stones at others yet when the truth is presented to you as you ask you deny it and then try to make something personal about it. Then you lie your butt off and claim innocence. What a hypocrite!!

http://www.sciencedaily.com/releases/2007/10/071021114804.htm
ScienceDaily (Oct. 22, 2007) — Although the ozone layer over the Antarctic this year is relatively small, this is due to mild temperatures in the region’s stratosphere this winter and is not a sign of recovery, the United Nations World Meteorological Organization (WMO) has said.
Since 1998, only the ozone holes of 2002 and 2004 have been smaller than this year’s – both in terms of area and amount of destroyed ozone – and this is not indicative of ozone recuperation, the agency said.
Instead, it is due to mild temperatures in the stratosphere, which still contains sufficient chlorine and bromine to completely destroy ozone in the 14-21 kilometer altitude range.
The amount of gases which diminish ozone in the Antarctic stratosphere peaked around the year 2000. However, despite the decline in the amount by 1 per cent annually, enough chlorine and bromine will be in the stratosphere for another decade or two, which could result in severe ozone holes, WMO said.

... Record low maximum temperature set in Denver for August 16th...
The high temperature at Denver International Airport today was 58

This 58 degree reading will replace the previous low maximum

Bunk!
Climate scientists have been measuring declines in the stratospheric ozone (4% per decade) since the 1960's, when certain chemicals like CFCs, which were used in refrigeration and air conditioning, began to be used in large numbers. Other chemicals, like the biocide methyl bromide, are also big destroyers of ozone. Unlike CFCs which phased out in the Montreal protoccol, most of these second tier chemicals continue to be used and continue to destroy stratospheric ozone. It is important to note that while we are seeing holes at the North and especially the South poles, the stratosphere is thinning everywhere.
And we see the health effects of this destruction -- significant increases in basal and squamous cell skin cancer as well as actinic keratoses. Tumor biologists also fear that other cancers, like the lymphomas, are solar attenuated. In otherwords, they are not directly caused by solar radiation, but affected by it. Other diseases and vaccines are affected as well. Measles vaccines work less successfully now, because of increased UV at the surface. Rates of leprosy are increasing because solar radiation depletes the ability of the skin to work as an effective member of our immune system. Scientists at the University of Texas have been studying this phenomena. What they also worry about is that our stratospheric ozone has always protected us against incoming UVC radiation. We don't know the health effects of being bombarded by that wavelength.
As to the ozone holes opening and closing, they are seasonal changes. At the South Pole, they occur in the polar spring of September to December. Throughout the year, the increased temperatures of the earth cause the ozone depleting chemicals to disassociate and wreck havoc in the ozone. During polar spring, the winds at that time of year combine with lack of sunlight to lower the temperature sufficiently to cause these disassociated particles to freeze into acids. It is the increased level of acids that cause the hole in the ozone. When the winds subside and the
And back to the use of the word theory. To the average man in the street, theory means a guess. Scientists do not use the term in the same way. Here is a link of a glossary of terms from NOAA.

Wouldn't it have been more beneficial if the word theory had actually been defined in that link?

Which begs my question from before? Why are the ozone holes in the arctic poles if they're from CO2 emissions? If this were true, holes in the ozone would appear above heavily industrialized nations, not the south pole.

Here's a link to a definition of theory. Causes the same problems when discussing evolution.
From the National Academy of Science as quoted in Wiki:
In science a theory is a testable model of the manner of interaction of a set of natural phenomena, capable of predicting future occurrences or observations of the same kind, and capable of being tested through experiment or otherwise verified through empirical observation. For the scientist, "theory" is not in any way an antonym of "fact". For example, it is a fact that an apple dropped on earth has been observed to fall towards the center of the planet, and the theories commonly used to describe and explain this behavior are Newton's theory of universal gravitation (see also gravitation), and the general theory of relativity.
In common usage, the word theory is often used to signify a conjecture, an opinion, a speculation, or a hypothesis. In this usage, a theory is not necessarily based on facts; in other words, it is not required to be consistent with true descriptions of reality. True descriptions of reality are more reflectively understood as statements which would be true independently of what people think about them.
According to the United States National Academy of Sciences,
Some scientific explanations are so well established that no new evidence is likely to alter them. The explanation becomes a scientific theory. In everyday language a theory means a hunch or speculation. Not so in science. In science, the word theory refers to a comprehensive explanation of an important feature of nature that is supported by many facts gathered over time. Theories also allow scientists to make predictions about as yet unobserved phenomena.

Which again begs the question why are there holes in the ozone at the poles? Shouldn't they be above the heaviy industrialized centers where there are supposed CO2 emissions?

Still waiting to see scientific facts from the "Global Warming Debunkers" here?
Its amazing that countless scientists, scientific agencies, institutions, educational bodies, et cetera, all agree with scientific evidence Global Warming is a fact of life.
Whereas here we have a few people considering dubious news articles, a local temperature on a cold day as indicators of Global Warming hoax!

Except those cold temperatures expand across the USA, not just in Denver.
When the people on the left reach the conclusion that they have been lied to and manipulated in order to give up their freedom, like those of us on the right, we will welcome you with open arms. Truth is universal and transcends political viewpoints. The only thing I am interested in is the truth and I refuse to let myself be manipulated by politicians who think they know better than me what's best for me. Anyone who tries to scare me and offer themselves as the saviour of my problems, deserves my contempt (I mean politicians, scientists with a political agenda.... a large number).

Which begs my question from before? Why are the ozone holes in the arctic poles if they're from CO2 emissions? If this were true, holes in the ozone would appear above heavily industrialized nations, not the south pole.  The holes in the ozone are not caused by CO2. No one ever said they were related to CO2. They're caused by chlrofluorocarbons and other chemicals. The layers of the atmosphere are thinner at the poles for the same reasons the earh is an oblate spheroid. Because the layers are thinner there, one of the thinnest layers (that containing ozone as one of its primary components) is stretched thin enough to be effectively absent at the highest latitudes at times. It doesn't matter where in the layer the destruction of the ozone occurs, that just thins the layer. If you could rotate a bottle of water at a constant speed that was enough to push water up against the sides, then even if you sucked water out of the bottle from against one side.. the level in the center would drop so that when it got low enough, there would be a "hole" in the water at the center of the bottle. It doesn't matter where it gets removed from, what matters is the remaining volume subject to physical forces.

Not bad NO.
In the past week you have tried to pawn yourself off to us as a structural engineer, an aviation engineer and now a climatologist.
When are you gonna start mixing Pina Colada's and Margaritas for us?

By that theory everything would be sucked to the center, clouds, rain, hurricanes, whatever. My point is that holes in the ozone aren't caused by man and that is another hoax hoisted on us in order to scare us and give others control of our lives. It's all about power, dude.

This isn’t a question of science. It’s a question of whether Americans can trust what the media tell them about science.

And you still don't understand the language well enough to know the difference between aviation engineering and aerodynamics, or between being a climatologist and knowing basic physical science that anyone who passed a high school science class could demonstrate to you. Just because you're ignorant and uneducated doesn't mean I'm trying to "pawn" myself "off" as anything.

Cooling trend
Scientists quoted in a past DailyTech article link the cooling to reduced solar activity which they claim is a much larger driver of climate change than man-made greenhouse gases. The dramatic cooling seen in just 12 months time seems to bear that out. While the data doesn't itself disprove that carbon dioxide is acting to warm the planet, it does demonstrate clearly that more powerful factors are now cooling it.

It seems pretty obvious the doubting Thomas's here are not switched on to science and their argument is purelly narrow-minded politically based. This is typical of "American" attitudes that the rest of the worlds International Environmental Agencies have had to face and suffer. Especially the United Nations Environmental Administration.
The US is the largest per capita emitter of carbon dioxide from burning fossil fuels in the world! China second. AND, out of 137 countries ratifying the Kyoto Protocol the US back peddled all away through it with the same similar BS in this thread.
Why is it despite 137 countires with varying government, political, economic and social interests can agree on Global Warming yet USA soap opera politics cant!!!!
Moronic, to say the least!
