This is not to say that we don’t face a serious problem. But the problem is political. Because of the mistaken idea that governments can and must do something about climate, pressures are building that have the potential of distorting energy policies in a way that will severely damage national economies, decrease standards of living, and increase poverty. This misdirection of resources will adversely affect human health and welfare in industrialized nations, and even more in developing nations. Thus it could well lead to increased social tensions within nations and conflict between them.
If not for this economic and political damage, one might consider the present concern about climate change nothing more than just another environmentalist fad, like the Alar apple scare or the global cooling fears of the 1970s. Given that so much is at stake, however, it is essential that people better understand the issue.

UGWC Hypothesis 1
Manmade emissions of greenhouse gases do not discernibly, significantly and predictably cause increases in global surface and tropospheric temperatures along with associated stratospheric cooling.
UGWC Hypothesis 2
The benefits equal or exceed the costs of any increases in global temperature caused by manmade greenhouse gas emissions between the present time and the year 2100, when all global social, economic and environmental effects are considered.
Entrants acknowledge that the concepts and terms mentioned and referred to in the UGWC hypotheses are inherently and necessarily vague, and involve subjective judgment.

Probably the best-known of the aerial geoengineering proposals was that put forward in 1997 by Edward Teller and entitled ‘Global Warming and the Ice Ages: Prospects for Physics-Based Modulation of Global Change’ subsequently popularised in the Wall Street Journal in an article entitled ‘The Planet Needs a Sunscreen’.
Teller proposed deliberate, large-scale introduction of reflective particles into the upper atmosphere, a task he claimed could be achieved for less than $1 billion a year, between 0.1 and 1.0 percent of the $100 billion he estimated it would cost to bring fossil fuel usage in the United States back down to 1990 levels, as required by the Treaty of Kyoto.
Characteristic of the politics of Teller is the fact that he both ridiculed the idea of global warming and at the same time put forward what he represented as a solution to global warming. ‘For some reason,’ Teller observed sarcastically, ‘This option isn't as fashionable as all-out war on fossil fuels and the people who use them.’

Teller says that cooling caused by volcanic eruptions shows this technique would work. For exmaple, the erruption of Mexico's El Chichon in the 1980s cooled the Northern Hemisphere by about one-quarter as much as the average prediction for global warming expected by 2100.
According to Teller, the director of the U.S. Global Change Research Program's Coordination Office has been promoting such geoengineering for three decades, and one National Academy of Sciences report a few years ago commented on "the relatively low costs at which some of the geoengineering options might be implemented."
Teller and his colleagues presented their proposal for geoengineering at the 22nd International Seminar on Planetary Emergencies in August 1997.

It will be noted that in October of 1997 a change in the reporting system of visibility data was reduced from a former maximum of 40 miles to a limit of 10 miles. It is a reasonable question to ask as to why that change was made, and whether or not it was made in anticipation of certain events to follow that involve large scale aircraft aerosol operations over large scale geographic regions.
It is observed that there are highly significant degradations in the visibility data immediately following this change in the reporting method. Immediately after this change, the dramatic increase in visibility reports of less than 10 miles is quite apparent.
The graphs shown are taken from climatic archive data available for Santa Fe, NM from Jan 1994 to Mar 2001. Three different time periods are shown to aid in demonstrating the magnitude of change which has occurred in visibility. The first graph shows all data available inclusive from Jan 1994 to Mar 2001. The second graph shows the transition zone during which the visibility standards were altered. This graph showns a period from Jan 1996 to Dec 1998; the change in reporting standard was made in Oct 1997. The third graph shows recent data, where visibility below 10 miles is now a regular occurrence. This graph shows the period from Jan 1999 to Mar 2001.

The proposed revisions address two categories of particulate matter: fine particles (PM2.5), which are 2.5 micrometers in diameter and smaller; and inhalable coarse particles (PM10-2.5), which are smaller than 10 micrometers in diameter but larger than PM2.5. EPA has had national air quality standards for fine particles since 1997 and for coarse particles 10 micrometers and smaller (PM10) since 1987
EPA last revised the particulate matter standards in 1997. Under terms of a consent decree, EPA agreed to propose whether to revise the particulate matter standards by December 20, 2005; and committed to finalizing any revisions to the standards by September 27, 2006.
Proposal to Revise the National Ambient Air Quality

Hi Stellar,
I think ideas such as pumping out cooling sulphates would work. Not sure it would be a good idea though. As we generally have a poor history of meddling with nature.
As for solar being the major cause of current warming (i.e. last few decades), the evidence suggests this is not the case. Solar activity has not increased for quite a few decades, being pretty consistent, even possibly falling in more recent decades.
Thus, solar can't fully account for the current warming trend, probably has some input (e.g., 10-25%'ish).
So one awkward question you can ask, when you’re forking out those extra taxes for climate change, is “Why is east Antarctica getting colder?” It makes no sense at all if carbon dioxide is driving global warming. While you’re at it, you might inquire whether Gordon Brown will give you a refund if it’s confirmed that global warming has stopped. The best measurements of global air temperatures come from American weather satellites, and they show wobbles but no overall change since 1999.

As for other human non-GHG causes (e.g., black carbon, habitat destruction/urbanisation), I would think they are having an impact, maybe a bit more than we currently think, maybe not.
I can tell you that second hand smoke is not a health hazard to anyone and never was, and the EPA has always known it. I can tell you that the evidence for global warming is far weaker than its proponents would ever admit. I can tell you the percentage the US land area that is taken by urbanization, including cities and roads, is 5%. I can tell you that the Sahara desert is shrinking, and the total ice of Antarctica is increasing. I can tell you that a blue-ribbon panel in Science magazine concluded that there is no known technology that will enable us to halt the rise of carbon dioxide in the 21st century. Not wind, not solar, not even nuclear. The panel concluded a totally new technology-like nuclear fusion-was necessary, otherwise nothing could be done and in the meantime all efforts would be a waste of time. They said that when the UN IPCC reports stated alternative technologies existed that could control greenhouse gases, the UN was wrong.

Also, only a few planets/moons are warming.
It's very unlikely that a 2'C warming on pluto is due to increases in solar activity, as this would suggest warming well in excess of 2'C here on earth (in fact, we would be baking).
Most likely each has it's own reason for warming apart from solar variations (i.e. local weather, orbital variations etc).
ABE: This guy has some of the research on the planetary warming issue.

You can start reading around post four and tell me what you think about that and the following.

May the possibility of the planet heating up not then have more to do with the Sun heating up and the global warming that seems to be taking place on all the planets in the inner solar system ?

Well ok BUT:
So the Sun is doing SOMETHING to most of the planets even if our scientist can not explain how or why; i wont accept the claim that it's just a 'coincidence'.
But it's not that much warmer if at all and certainly not on average.

It's interesting that a former of editor of New Scientist would feel so very strongly about that, right?
So we are going to destroy hundreds of millions of lives all over the world but when we are clearly not sure?
Kinda like his approach and i have validated the claims to the best of my abilities. ....
I can show you evidence that almost all are which either means there are humans on all of them ( John Lear would tell you so... ) or the Sun is doing SOMETHING somehow...
Well i just provided you with data that suggest we can influence the global weather patterns by means of introduction of particulant matter; have you ever heard of chem trails?
I know that it suits many agenda's to believe that but personally i do not believe in that type of 'coincidences'.
I think i supplied some sources earlier one showing the other side of that story...

WASHINGTON, Sept. 12 /PRNewswire-USNewswire/ -- A new analysis of peer-reviewed literature reveals that more than 500 scientists have published evidence refuting at least one element of current man-made global warming scares. More than 300 of the scientists found evidence that 1) a natural moderate 1,500-year climate cycle has produced more than a dozen global warmings similar to ours since the last Ice Age and/or that 2) our Modern Warming is linked strongly to variations in the sun's irradiance. "This data and the list of scientists make a mockery of recent claims that a scientific consensus blames humans as the primary cause of global temperature increases since 1850," said Hudson Institute Senior Fellow Dennis Avery.

Eh? So, there are natural changes in climate. I don't think any half-intelligent climatologist would deny this. This essentially means little to the causes of current warming.

On the Cause of the 1930s Dust Bowl

During the 1930s, the United States experienced one of the most devastating droughts of the past century. The drought affected almost two-thirds of the country and parts of Mexico and Canada and was infamous for the numerous dust storms that occurred in the southern Great Plains. In this study, we present model results that indicate that the drought was caused by anomalous tropical sea surface temperatures during that decade and that interactions between the atmosphere and the land surface increased its severity. We also contrast the 1930s drought with other North American droughts of the 20th century.

You know what I mean: THE TREND. Are you suggesting that 1934 was the only year? As if there isn't a 30 year trend all throughout?
Plus that study is about the drought. Drought as in dry. That's the model for the drought, not the climate. Explain where the 30 year trends came from. Let's hear your mechanism. What causes the 30 year trends? Considering the graphs I provided it appears quite obvious that neither the sun nor CO2 'drove' much during that 'spell'.
