Are you insane? This is a guide for classroom experiments where it has been performed thousands of times. It is designed to create equal conditions for both bottles. The picture is an example, not a picture of the only time the experiment was performed or whatever the hell you think it is, Dufus. I'm looking at the picture and there is a black "stand" under both bottles. They are both two liter bottles. The temperature probes are inside the bottles, as you would know if you had actually read the experiment. That you did not read it is further illustrated by the fact that the difference in temperatures was 4°C, not 2°. You are an idiot.
And it is NOT a robust experiment...look that one up too if you wish. These are all experiments that fail at the basic level of control of outside influences. Please take this photo to a university physics professor and see what he or she says. I dare you.
I'm afraid all that is just your ignorant and very unscientific opinion and has nothing to do with reality. The experiment is very simple and straightforward. There are no "outside influences" because there is just the two bottles and the same light passing through both of them. One bottle has more CO2 in it and consequently absorbs more of the infrared portion of the light and gets hotter. Your pretense that you know anything about physics or what physics professors would say is really pathetic.
In fact the physicists are pretty clear about their position.
Scientific opinion on climate change
(very partial list)
American Institute of Physics
The Governing Board of the American Institute of Physics endorsed the AGU statement on human-induced climate change:[30]
The Governing Board of the American Institute of Physics has endorsed a position statement on climate change adopted by the American Geophysical Union (AGU) Council in December 2003.
American Physical Society
In November 2007, the American Physical Society (APS) adopted an official statement on climate change:
Emissions of greenhouse gases from human activities are changing the atmosphere in ways that affect the Earth's climate. Greenhouse gases include carbon dioxide as well as methane, nitrous oxide and other gases. They are emitted from fossil fuel combustion and a range of industrial and agricultural processes.
The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.
Because the complexity of the climate makes accurate prediction difficult, the APS urges an enhanced effort to understand the effects of human activity on the Earth’s climate, and to provide the technological options for meeting the climate challenge in the near and longer terms. The APS also urges governments, universities, national laboratories and its membership to support policies and actions that will reduce the emission of greenhouse gases.[31]
Australian Institute of Physics
In 2005, the Australian Institute of Physics (AIP) issued a science policy document in which they stated:
Policy: The AIP supports a reduction of the green house gas emissions that are leading to increased global temperatures, and encourages research that works towards this goal.
Reason: Research in Australia and overseas shows that an increase in global temperature will adversely affect the Earth’s climate patterns. The melting of the polar ice caps, combined with thermal expansion, will lead to rises in sea levels that may impact adversely on our coastal cities. The impact of these changes on biodiversity will fundamentally change the ecology of Earth.[32]
European Physical Society
In 2007, the European Physical Society issued a position paper regarding energy:
The emission of anthropogenic greenhouse gases, among which carbon dioxide is the main contributor, has amplified the natural greenhouse effect and led to global warming. The main contribution stems from burning fossil fuels. A further increase will have decisive effects on life on earth. An energy cycle with the lowest possible CO2 emission is called for wherever possible to combat climate change.[33]
European Science Foundation
In 2007, the European Science Foundation issued a Position Paper on climate change:
There is now convincing evidence that since the industrial revolution, human activities, resulting in increasing concentrations of greenhouse gases have become a major agent of climate change. These greenhouse gases affect the global climate by retaining heat in the troposphere, thus raising the average temperature of the planet and altering global atmospheric circulation and precipitation patterns.
While on-going national and international actions to curtail and reduce greenhouse gas emissions are essential, the levels of greenhouse gases currently in the atmosphere, and their impact, are likely to persist for several decades. On-going and increased efforts to mitigate climate change through reduction in greenhouse gases are therefore crucial.[34]
Federation of Australian Scientific and Technological Societies
In 2008, the Federation of Australian Scientific and Technological Societies (FASTS) issued a policy statement on climate change:
Global climate change is real and measurable. Since the start of the 20th century, the global mean surface temperature of the Earth has increased by more than 0.7°C and the rate of warming has been largest in the last 30 years.
Key vulnerabilities arising from climate change include water resources, food supply, health, coastal settlements, biodiversity and some key ecosystems such as coral reefs and alpine regions. As the atmospheric concentration of greenhouse gases increases, impacts become more severe and widespread. To reduce the global net economic, environmental and social losses in the face of these impacts, the policy objective must remain squarely focused on returning greenhouse gas concentrations to near pre-industrial levels through the reduction of emissions.
The spatial and temporal fingerprint of warming can be traced to increasing greenhouse gas concentrations in the atmosphere, which are a direct result of burning fossil fuels, broad-scale deforestation and other human activity.[35]
Earth sciences
American Geophysical Union
The American Geophysical Union (AGU) statement,[36] adopted by the society in 2003 and revised in 2007, affirms that rising levels of greenhouse gases have caused and will continue to cause the global surface temperature to be warmer:
The Earth's climate is now clearly out of balance and is warming. Many components of the climate system—including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons—are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century. Global average surface temperatures increased on average by about 0.6°C over the period 1956–2006. As of 2006, eleven of the previous twelve years were warmer than any others since 1850. The observed rapid retreat of Arctic sea ice is expected to continue and lead to the disappearance of summertime ice within this century. Evidence from most oceans and all continents except Antarctica shows warming attributable to human activities. Recent changes in many physical and biological systems are linked with this regional climate change. A sustained research effort, involving many AGU members and summarized in the 2007 assessments of the Intergovernmental Panel on Climate Change, continues to improve our scientific understanding of the climate.
