“At least 60% of the warming of the Earth observed since 1970 appears to be induced by natural cycles which are present in the solar system. A climatic stabilization or cooling until 2030-2040 is forecast by the phenomenological model.”

“If both Mars and Earth are experiencing global warming, then maybe there is a larger phenomenon going on in the Solar System that is causing their global climates to change, like changes in the Sun.”

Anthony Watts (1958) American television meteorologist

“Mars, Triton, Pluto and Jupiter all show global warming. Climate changes on other planets and their moons show that climate change elsewhere in the Solar System could not possibly be due to human activity on Earth. There must be a driving force outside the Earth. It is the Sun.”

“Since 1895, the media has alternated between global cooling and warming scares during four separate and sometimes overlapping time periods. From 1895 until the 1930’s the media peddled a coming ice age. From the late 1920's until the 1960's they warned of global warming. From the 1950's until the 1970's they warned us again of a coming ice age. This makes modern global warming the fourth estate's fourth attempt to promote opposing climate change fears during the last 100 years.”

“You would think that we’d know the Earth’s ‘climate sensitivity’ by now, but it has been surprisingly difficult to determine. How atmospheric processes like clouds and precipitation systems respond to warming is critical, as they are either amplifying the warming, or reducing it. This website currently concentrates on the response of clouds to warming, an issue which I am now convinced the scientific community has totally misinterpreted when they have measured natural, year-to-year fluctuations in the climate system. As a result of that confusion, they have the mistaken belief that climate sensitivity is high, when in fact the satellite evidence suggests climate sensitivity is low.”

“Have the climate models been successful in predicting anything? They, of course, predict substantial global warming. This is not surprising given the expressed belief of some of the model builders in the global warming hypothesis and the many parameters in the model that need to be introduced. However, the models also predict unambiguously that the atmosphere is warming faster than the surface of the earth; but all the available observational data unambiguously shows the opposite! Truth in science is always determined from observational facts. One finds the truth by making a hypothesis and comparing observations with the hypothesis. It is absolutely essential that one should be neutral and not fall in love with the hypothesis. If the facts are contrary to any predictions, then the hypothesis is wrong no matter how appealing. "Truth by Assertion" is not science.”

“Among complex systems, stability is typically meta-stability, which is preserved through cycling, whilst growth and shrinkage are often components of a larger-scale, cyclic wave.”

“The surya namaskar is essentially about building a dimension within you where your physical bodily cycles are in sync with the sun’s cycles, which run about twelve and a quarter years. It is not by accident but by intent that it has been structured with twelve postures. If your system is in a certain level of vibrancy and readiness, and in a high state of receptivity, then naturally your cycle will be in sync with the solar cycle. Young”

“Mars has global warming, but without a greenhouse and without the participation of Martians. These parallel global warmings -- observed simultaneously on Mars and on Earth -- can only be a straightline consequence of the effect of the one same factor: a long-time change in solar irradiance.”

Khabibullo Abdusamatov (1940) Russian astrophysicist

as quoted by Lawrence Solomon in Look to Mars for the truth on global warming http://www.canada.com/nationalpost/story.html?id=edae9952-3c3e-47ba-913f-7359a5c7f723&k=0/, National Post, January 26, 2007.

“"Global warming" suggests a steady linear increase in temperature, but since that isn't happening, proponents have shifted to the more universal term "climate change," which can be liberally applied to just about anything observable in the atmosphere.”
