Global warming not man-made phenomenon

Global warming will not be helped much by efforts to reduce carbon dioxide emission into the atmosphere, say two scientists who have studied the matter.
Dr. Nir Shaviv, an astrophysicist from the Racah Institute of Physics of the Hebrew University of Jerusalem, and Prof. Jan Veiser a geochemist at the University of Ottawa in Canada and Ruhr University in Germany, say that temperature variations are due more to cosmic forces than to the actions of man.
In a recent article published in GSA Today (the journal of the Geographic Society of America) and described in Nature, Shaviv and Veiser tell of their studies illustrating a correlation between past cosmic ray flux ? the high-energy particles reaching us from stellar explosions -- and long-term climate variability, as recorded by oxygen isotopes trapped in rocks formed by ancient marine fossils. The level of cosmic ray activity reaching the earth and its atmosphere is reconstructed using another isotopic record in meteorites.
The study showed that peak periods of cosmic rays reaching the earth over the past 550 million years coincided with lower global temperatures, apparently due to the way that the cosmic rays promote low-level cloud formation (hence blocking out sun warming). No correlation was obtained, however, with the changing amount of atmospheric carbon dioxide.
The conclusion of the two scientists is, therefore, that celestial processes seem to be the dominant influence on climate change, and that increased carbon dioxide release, while certainly not beneficial, is only secondary to those forces which are beyond our control.
In practical terms, says Dr. Shaviv, "The operative significance of our research is that a significant reduction of the release of greenhouse gases will not significantly lower the global temperature, since only about a third of the warming over the past century should be attributed to man." Thus, say the scientists, the Kyoto accord of 1997 -- which was aimed at tackling the global warming phenomenon through limitations on carbon dioxide -- is not the panacea some thought it would be.
Taking the long-range view, Dr. Shaviv and Prof. Veiser believe that fluctuations in cosmic ray emissions account for about 75 percent of climate variation throughout the millennia. They acknowledge that this position pits them against prevailing scientific opinion, which still places a heavy emphasis on the negative role of greenhouse gases.

Plants have filed a class action lawsuit to stop any actions to reduce CO2 --- such action would seriously harm all plants. They are asking for $3 trillion damages.
A life is a life, and what right do any of us have to say that the rights of animal life is more important than the rights of plant life?

I reckon that's enough to demonstrate at least that I was not imagining it :)

The idea that particles from stellar explosions millions of years and billions of miles of away account for 75% of "climate change" on our planet is absolutely absurd.
Why do you say that?
Well the fact that we have our very own 27,000,000° star a mere 93 million miles away would be but one reason among many. I tend to think that its well-known variations in output might account for a larger effect on our planet's fluctuating temperature than stars that blew up millions of years ago, billions of miles away.

interesting stuff about mars... i have always felt that the sun is pulling the planets closer and closer and that eventually we will be drawn out of the orbit of life and that mars will be the next to benefit from our demise...
it is our destiny to be able to reach her before we cook...
perhaps i watch too much sci fi channel...

no problem. I hope you find these data useful against the chicken-littles.

This "Global Warming" is not all bad. Eureka Ca is setting warmer temp records once or twice a week. Last Thursday it reached a new record for the day of 71 degrees and repeated it on Sunday...

It's better than useful. It's almost too perfect. It's going to make for a dandy sound bite.

I have been pleased to note the remarkable shade of purple they turn when Mars is casually dumped on their narrow little shoulders. Have fun!

You mean it's all relative? The sky is not falling? What a relief.

Could the Mars warming be also due to the fact that Mars is getting closer to the Earth, hence the Sun?
Mars is supposed to be at its closest point to Earth, some 34 million miles, since the Neanderthals roamed the planet.
To: AFreeBird
Mars and Earth are at their closest approach in 5000 years, yes. This is a function of the mechanics of their combined orbits. We are near aphelion at the same time this time around that Mars is at perihelion, and for once we are on the same side of the sun. It is a matter of the way the orbits worked out.
However, Mars' aphelion and perihelion are the same they have always been.

Okay, thanks for the clarification. I hadn't considered that aspect of the equation.
To: RussianConservative
The 1/3 is the average warming. The 75% is the variation in such warning.

"The idea that particles from stellar explosions millions of years and billions of miles of away account for 75% of "climate change" on our planet is absolutely absurd."
It's actually quite simple. Solar activity determines how much of this "cosmic rain" reaches the atmosphere to affect the degree of cloud cover.
One might not be able to control the "rain," but the sun is like an "umbrella" that shifts into and out of position.
