There is no scientific evidence that human activity is causing the planet to warm, according to Greenpeace co-founder Patrick Moore, who testified in front of a Senate committee on Tuesday.
Moore argued that the current argument that the burning of fossil fuels is driving global warming over the past century lacks scientific evidence. He added that the Earth is in an unusually cold period and some warming would be a good thing.
“There is no scientific proof that human emissions of carbon dioxide (CO2) are the dominant cause of the minor warming of the Earth’s atmosphere over the past 100 years,” according to Moore’s prepared testimony.
There is no scientific proof that human emissions of carbon dioxide (CO2) are the dominant cause of the minor warming of the Earth’s atmosphere over the past 100 years. If there were such a proof it would be written down for all to see. No actual proof, as it is understood in science, exists.
At this point I could care less if it is humans that caused it or not. This constant arguing as to the why of it, is taking away from the argument we should be having. Which is; What can we do about it?. It is time to find solutions all this blame game crap is simply a distraction.
The Koch Brothers (and others of their ilk) don't want to face up to their societal obligations. Constant arguments (many funded directly by the Koch's) are nothing more than a distraction.
“There is no scientific proof that human emissions of carbon dioxide (CO2) are the dominant cause of the minor warming of the Earth’s atmosphere over the past 100 years,”
Human interference had altered the surface of the earth long before the present era (Thomas, 1956). The first major change started about 7000 years ago when man developed agriculture. This led to systematic changing of forested areas to fields and pastures. Other reasons for deforestation were the needs for structural timber and lumber. In recent times, paper requirements have led to large-scale reductions of forests. Only gradually is a systematic harvesting and replacement policy taking over.
Agriculture and lumbering have undoubtedly led to mesoscale climatic changes, but these are poorly documented, although one can make some approximate guesses at their magnitude. In many instances secondary changes have been more far-reaching. After the clearing, wind and water erosion have washed or blown the top soil away. Bare rock has become exposed, and now far more extreme temperatures and lower humidities prevail where once the even-tempered mesoclimate of the forest dominated. Stretches of Anatolia, the Spanish plateau, and some slopes of the Italian Apennines are silent witnesses to this development.
But by far the most alarming development has been the substitution of rocklike, well-compacted, impermeable surfaces for vegetated soil, a development that is the natural consequence of urbanization. Square kilometer after square kilometer has yielded to the bulldozer and has been converted to buildings, highways, and parking lots. Reservoirs and irrigation also have become important.
Svensmark's Theory Explained
Man-made climate change may be happening at a far slower rate than has been claimed, according to controversial new research.
Scientists say that cosmic rays from outer space play a far greater role in changing the Earth's climate than global warming experts previously thought.
In a book, to be published this week, they claim that fluctuations in the number of cosmic rays hitting the atmosphere directly alter the amount of cloud covering the planet.
High levels of cloud cover blankets the Earth and reflects radiated heat from the Sun back out into space, causing the planet to cool.
Henrik Svensmark, a weather scientist at the Danish National Space Centre who led the team behind the research, believes that the planet is experiencing a natural period of low cloud cover due to fewer cosmic rays entering the atmosphere.
This, he says, is responsible for much of the global warming we are experiencing.
He claims carbon dioxide emissions due to human activity are having a smaller impact on climate change than scientists think. If he is correct, it could mean that mankind has more time to reduce our effect on the climate.
The controversial theory comes one week after 2,500 scientists who make up the United Nations International Panel on Climate Change published their fourth report stating that human carbon dioxide emissions would cause temperature rises of up to 4.5 C by the end of the century.
Mr Svensmark claims that the calculations used to make this prediction largely overlooked the effect of cosmic rays on cloud cover and the temperature rise due to human activity may be much smaller.
He said: "It was long thought that clouds were caused by climate change, but now we see that climate change is driven by clouds.
"This has not been taken into account in the models used to work out the effect carbon dioxide has had.
"We may see CO2 is responsible for much less warming than we thought and if this is the case the predictions of warming due to human activity will need to be adjusted."
Mr Svensmark last week published the first experimental evidence from five years' research on the influence that cosmic rays have on cloud production in the Proceedings of the Royal Society Journal A: Mathematical, Physical and Engineering Sciences. This week he will also publish a fuller account of his work in a book entitled The Chilling Stars: A New Theory of Climate Change.
Cosmic rays and climate change over the past 1000 million years

The Galactic cosmic ray (GCR) intensity has been postulated by others to vary cyclically with a peak to valley ratio of ~3:1, as the Solar System moves from the Spiral Arm to the Inter-Arm regions of the Galaxy. These intensities have been correlated with global temperatures and used to support the hypothesis of GCR induced climate change. In this paper we show that the model used to deduce such a large ratio of Arm to Interarm GCR intensity requires unlikely values of some of the GCR parameters, particularly the diffusion length in the interstellar medium, if as seems likely to be the case, the diffusion is homogeneous. Comparison is made with the existing gamma ray astronomy data and this also indicates that the ratio is not large.The variation in the intensity is probably of order 10-20% and should be no more than 30% as the Solar System moves between these two regions, unless the conventional parameters of the GCR are incorrect. The variation in the intensity is probably of order 10-20% and should be no more than 30% as the Solar System moves between these two regions, unless the conventional parameters of the GCR are incorrect. In addition we show that the variation of the GCR intensity, as the trajectory of the Solar System oscillates about the Galactic Plane, is too small to account for the extinctions of species as has been postulated unless, again, conventional assumptions about the GCR parameters are not correct.
The cosmic ray link between solar activity and the terrestrial climate. The changing solar activity is responsible for a varying solar wind strength. A stronger wind will reduce the flux of cosmic ray reaching Earth, since a larger amount of energy is lost as they propagate up the solar wind. The cosmic rays themselves come from outside the solar system (cosmic rays with energies below the "knee" at 1015eV, are most likely accelerated by supernova remnants). Since cosmic rays dominate the tropospheric ionization, an increased solar activity will translate into a reduced ionization, and empirically (as shown below), also to a reduced low altitude cloud cover. Since low altitude clouds have a net cooling effect (their "whiteness" is more important than their "blanket" effect), increased solar activity implies a warmer climate. Intrinsic cosmic ray flux variations will have a similar effect, one however, which is unrelated to solar activity variations.
- Greenpeace founders
The current Greenpeace web site lists the founders of The Don't Make a Wave Committee as Dorothy and Irving Stowe, Marie and Jim Bohlen, Ben and Dorothy Metcalfe, and Robert Hunter. According to both Patrick Moore and an interview with Dorothy Stowe, Dorothy Metcalfe, Jim Bohlen and Robert Hunter, the founders of The Don't Make a Wave Committee were Paul Cote, Irving and Dorothy Stowe and Jim and Marie Bohlen

There has to be a better way.
"the science is settled"
Moore’s comments come after Secretary of State John Kerry and President Obama declared global warming not only a “fact,” but a matter of national security; rivaling weapons of mass destruction.
No matter if we are, or are not, now affecting our climate today, that is overshadowed by the fact that climate always changes on its own and it will not stay as it is now anyway.
