Thanks to hackers (or an insider) who broke into The University of East Anglia's Climatic Research Unit (CRU) and downloaded 156 megaybytes of data including extremely damaging emails, we now know that data supporting the global warming thesis was completely fabricated....

Arrhenius' high absorption values for CO2, however, met criticism by Knut Ångström in 1900, who published the first modern infrared spectrum of CO2 with two absorption bands. Arrhenius replied strongly in 1901 (Annalen der Physik), dismissing the critique altogether. He touched the subject briefly in a technical book titled Lehrbuch der kosmischen Physik (1903). He later wrote Världarnas utveckling (1906), German translation: Das Werden der Welten (1907), English translation: Worlds in the Making (1908) directed at a general audience, where he suggested that the human emission of CO2 would be strong enough to prevent the world from entering a new ice age, and that a warmer earth would be needed to feed the rapidly increasing population. He was the first person to predict that emissions of carbon dioxide from the burning of fossil fuels and other combustion processes would cause global warming. Arrhenius clearly believed that a warmer world would be a positive change.
Arrhenius estimated that halving of CO2 would decrease temperatures by 4 - 5 °C (Celsius) and a doubling of CO2 would cause a temperature rise of 5 - 6 °C

Researcher Finds Solar Trend That Can Warm Climate
Ends debate over whether sun can play a role in climate change
Since the late 1970s, the amount of solar radiation the sun emits during times of quiet sunspot activity has increased by nearly .05 percent per decade, according to the study. “This trend is important because, if sustained over many decades, it could cause significant climate change,” said Willson, a researcher affiliated with NASA Goddard Institute for Space Studies and the Earth Institute at Columbia University, and lead author of the study recently published in Geophysical Research Letters.
“Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century,” says Willson. “If a trend comparable the one found in this study persisted during the 20th century it would have provided a significant component of the global warming that the Intergovernmental Panel on Climate Change report claims to have occurred over the last 100 years.”
Willson found errors in previous satellite data that had obscured the trend. The new analysis, Willson says, should put an end to a debate in the field over whether solar irradiance variability can play a significant role in climate change.
The solar cycle occurs approximately every 11 years when the sun undergoes a period of increased magnetic and sunspot activity called the "solar maximum," followed by a quiet period called the "solar minimum." A trend in the average solar radiation level over many solar magnetic cycles would contribute to climate change in a major way. Satellite observations of total solar irradiance have now obtained a long enough record (over 24 years) to begin looking for this effect.
......................
In order to investigate the possibility of a solar trend, Willson needed to put together a long-term dataset of the Sun’s total output. Six overlapping satellite experiments have monitored TSI since late 1978.The first record came from the National Oceanic and Atmospheric Administration’s (NOAA) Nimbus7 Earth Radiation Budget (ERB) experiment (1978-1993). Other records came from NASA’s Active Cavity Radiometer Irradiance Monitors: ACRIM1 on the Solar Maximum Mission (1980-1989), ACRIM2 on the Upper Atmosphere Research Satellite (1991-2001) and ACRIM3 on the ACRIMSAT satellite (2000 to present). Also, NASA launched its own Earth Radiation Budget Experiment on its Earth Radiation Budget Satellite (ERBS) in 1984. And, the European Space Agency’s (ESA) SOHO/VIRGO experiment also provided an independent data set during 1996-1998.
In this study, Willson, who is also Principal Investigator of the ACRIM experiments, compiled a TSI record of over 24 years by carefully piecing together the overlapping records. In order to construct a long-term dataset, Willson needed to bridge a two-year gap (1989-1991) between ACRIM1 and ACRIM2. Both the Nimbus7/ERB and ERBS measurements overlapped the ACRIM ‘gap.’ Using Nimbus7/ERB results produced a 0.05 percent per decade upward trend between solar minima, while ERBS results produced no trend. Until this study, the cause of this difference, and hence the validity of the TSI trend, was uncertain. Now, Willson has identified specific errors in the ERBS data responsible for the difference. The accurate long-term dataset therefore shows a significant positive trend (.05 percent per decade) in TSI between the solar minima of solar cycles 21 to 23 (1978 to present).

Anyway, what would convince me that mamade global warming is false?
Well, obvious it would require disproving the work of Fourier, Arrhenius, Tyndall etal. One would also have to show that temperature data from urban areas is wrong and this there is no urban heat island effect. Also, that no human actibity affects cloud cover in anyway, nor Earth's albedo.
In fact, one would have to show that if there had never been a human on the planet then, all else being equal, every single place on the planet would still be exactly the same temperature ....... Okay, in the absence of an identical earth from a parallel universe, we'd have to use a computer simulation. But maybe something for the deniers to consider?
Of course, climate change due to human activity isn't just down to temperature/global warming. So we'd then have to do the same again for rainfall ....... Show that every single place on the planet gets exactly the same rainfall today as it would had no human ever existed.

Geographically distributed predictions of future climate, obtained through climate models, are widely used in hydrology and many other disciplines, typically without assessing their reliability. Here we compare the output of various models to temperature and precipitation observations from eight stations with long (over 100 years) records from around the globe. The results show that models perform poorly, even at a climatic (30-year) scale. Thus local model projections cannot be credible, whereas a common argument that models can perform better at larger spatial scales is unsupported.
The widely accepted (albeit unproven) theory that manmade global warming will accelerate itself by creating more heat-trapping clouds is challenged this month in new research from The University of Alabama in Huntsville.
Instead of creating more clouds, individual tropical warming cycles that served as proxies for global warming saw a decrease in the coverage of heat-trapping cirrus clouds, says Dr. Roy Spencer, a principal research scientist in UAHuntsville's Earth System Science Center.
That was not what he expected to find.
"All leading climate models forecast that as the atmosphere warms there should be an increase in high altitude cirrus clouds, which would amplify any warming caused by manmade greenhouse gases," he said. "That amplification is a positive feedback. What we found in month-to-month fluctuations of the tropical climate system was a strongly negative feedback. As the tropical atmosphere warms, cirrus clouds decrease. That allows more infrared heat to escape from the atmosphere to outer space."
The results of this research were published today in the American Geophysical Union's "Geophysical Research Letters" on-line edition. The paper was co-authored by UAHuntsville's Dr. John R. Christy and Dr. W. Danny Braswell, and Dr. Justin Hnilo of Lawrence Livermore National Laboratory, Livermore, CA.

Abstract Observations from the International Satellite Cloud Climatalogy Project (ISCCP) are used to demonstrate that the 19-level HadAM3 version of the United Kingdom Met Office Unified Model does not simulate sufficient high cloud over land. By using low-altitude winds, from the European Centre for Medium Range Weather Forecasting (ECMWF) Re-Analysis from 1979 to 1994 (ERA-15) to predict the areas of maximum likelihood of orographic wave generation, it is shown that much of the deficiency is likely to be due to the lack of a representation of the orographic cirrus generated by sub-grid scale orography. It is probable that this is a problem in most GCMs.
Who was debating about the Sun effecting Climate. Of course it does, its the bloody Sun. The argument is regarding Anthropogenic causes increasing warming.

Ends debate over whether sun can play a role in climate change
I call your Earth Institute article and raise you with some other Earth Institute archives.

Stalled Economy or Not, Record Year for CO2 Emissions
People Still Consumed More Per Capita in 2008
Per capita CO2 emissions are rising despite global recession
Each person on the planet produced 1.3 tons of carbon last year—an all-time high--despite a global recession that slowed the growth of fossil fuel emissions for the first time this decade, according to a report published this week in the journal Nature Geoscience. Emissions grew 2 percent last year, to total 8.7 billion tons of carbon dioxide.
So here we have two articles. One showing the increase in Anthropogenic CO2 emissions and another study on Oceanic absorption of CO2 now in decline(as predicted) due to its inability to cope with CO2 emissions. If we agree that the Ocean is a climate regulator and that we agree that we are increasing the amount of CO2 in both the Ocean as well as the atmosphere, then can we not agree that this is Anthropogenic effect on a Climate Regulator, that being the Ocean. That we are effecting change via Anthropogenic activity on a system of climate regulation?
Oceans' Uptake of Manmade Carbon May be Slowing
First Year-by-Year Study, 1765-2008, Shows Proportion Declining
The oceans play a key role in regulating climate, absorbing more than a quarter of the carbon dioxide that humans put into the air. Now, the first year-by-year accounting of this mechanism during the industrial era suggests the oceans are struggling to keep up with rising emissions—a finding with potentially wide implications for future climate. The study appears in this week’s issue of the journal Nature, and is expanded upon in a separate website.
Oceanic Influences and Interactions with Weather Systems
The world's oceans are the largest regulator of weather and climate systems. Covering more than 70% of the world, the temperatures, weather systems, and and circulation patterns over the ocean regulate the type of weather your local area will get. Find out how ENSO (The El Nino Southern Oscillation) could affect you. Will there be more hurricanes as a result? Find out now by exploring the subtopics below.
The CSIRO team analysed thousands of temperature and salinity data samples collected between 1950 and 2002 by research ships, robotic ocean monitors and satellites in the region between 60°S and the Equator. They identified linkages between these gyres to form a global-scale ‘supergyre’ that transfers water to all three ocean basins.
Mr Ridgway and co-author Mr Jeff Dunn say identification of the supergyre improves the ability of researchers to more accurately explain how the ocean governs global climate.
So here we have Wilson suggesting that IF the trend observed in the Late 19th century WAS comparable and persisted INTO the 20th THEN it would be significant. Which it would be and is, but that does not make 6 billion people vanish, does it? That does not make all the changes we have made insignificant, does it?
“Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century,” says Willson. “If a trend comparable the one found in this study persisted during the 20th century it would have provided a significant component of the global warming that the Intergovernmental Panel on Climate Change report claims to have occurred over the last 100 years.”

In other words the net radiation has remained about the same.
Chen et al (2002) suggest these changes in the tropics are related
to natural climate variability in the strength of the larger scale
Hadley and Walker circulations, variability that has long been
known about and is simply another periodic atmospheric pro-
cess (like El Niño, or the North Atlantic Oscillation).
To assess the impact of greenhouse gases on global warming,
one needs to consider the radiation over the entire globe, not
just the tropics. Greenhouse gases absorb long-wave radiation
from the surface at particular frequencies. Harries et al (2001)
showed that between 1970 and 1997 significant changes oc-
curred in the global radiation emitted to space at these frequen-
cies. This result is particularly important as it means that we are
directly observing more radiation absorbed by the increasing
amount of greenhouse gases. This alone is clear scientific evi-
dence for a significant human contribution to the observed
global warming.
Yes, we know the sun effects the climate. It is the Sun.
Willson found errors in previous satellite data that had obscured the trend. The new analysis, Willson says, should put an end to a debate in the field over whether solar irradiance variability can play a significant role in climate change.

Claims that increased solar activity is the cause of global warming - rather than man-made greenhouse gases - have been comprehensively disproved by a detailed study of the Sun.
Scientists have delivered the final blow to the theory that recent global warming can be explained by variations in the natural cycles of the Sun - a favourite refuge for climate sceptics who dismiss the influence of greenhouse-gas emissions.
Dr Lockwood and his colleague Claus Fröhlich, of the World Radiation Centre in Davos Dorf, Switzerland, have produced the most powerful counter argument to suggestions that current warming is part of the natural cycle of solar activities. "There is considerable evidence for solar influence on Earth's pre-industrial climate, and the Sun may well have been a factor in post-industrial change in the first half of the last century," they write.
However, since about 1940 there has been no evidence to suggest that increases in global average temperatures were caused by solar activity. "Our results show that the observed rapid rise in global mean temperatures seen after 1985 cannot be ascribed to solar variability, whichever of the mechanisms is invoked and no matter how much the solar variation is amplified," the two scientists said.
Monitoring TSI variability is clearly an important component of climate change research, particularly in the context of understanding the relative forcings of natural and anthropogenic processes.
