New peer-reviewed paper in Science should end the global warming debate

Here is the link to the published paper in Science. (H/T Watts Up With That via ECM)

Excerpt from the press release:

CORVALLIS, Ore. – A team of researchers says it has largely put to rest a long debate on the underlying mechanism that has caused periodic ice ages on Earth for the past 2.5 million years – they are ultimately linked to slight shifts in solar radiation caused by predictable changes in Earth’s rotation and axis.

In a publication to be released Friday in the journal Science, researchers from Oregon State University and other institutions conclude that the known wobbles in Earth’s rotation caused global ice levels to reach their peak about 26,000 years ago, stabilize for 7,000 years and then begin melting 19,000 years ago, eventually bringing to an end the last ice age.

The melting was first caused by more solar radiation, not changes in carbon dioxide levels or ocean temperatures, as some scientists have suggested in recent years.

“Solar radiation was the trigger that started the ice melting, that’s now pretty certain,” said Peter Clark, a professor of geosciences at OSU. “There were also changes in atmospheric carbon dioxide levels and ocean circulation, but those happened later and amplified a process that had already begun.”

That should be the end of global warming alarmism, but it won’t be, because this whole brouhaha isn’t about science. It’s about money and power. The power to control other people. The power to control the free market. So it doesn’t matter if solar radiation cycles cause global warming as a matter of fact, because facts don’t decide here.

Here’s a helpful quote from the neo-Darwinian George Gaylor Simpson that ECM sent me from Uncommon Descent:

The verdict of paleontologists is practically unanimous: almost all agree in opposing [Alfred Wegener’s hypothesis that the continents used to be one land mass and have since drifted apart]… The fact that almost all paleontologists say that the paleontological data oppose the various theories of continental drift should, perhaps, obviate further discussion of this point … It must be almost unique in scientific history for a group of students admittedly without special competence in a given field thus to reject the all but unanimous verdict of those who do have such competence.

George Gaylord Simpson, “Mammals and the Nature of Continents”, American Journal of Science 241 (1943): 1-31, p. 2.

Yes, there was a time when the consensus of scientists was against the theory of continental drift. Something to keep in mind.

NASA study links solar activity and global warming

Watts Up With That is reporting that a NASA study is FINALLY acknowledging that the Sun is responsible for past warming not man! (H/T Small Dead Animals)

Excerpt:

A study from NASA’s Goddard Space Flight Center in Greenbelt, Maryland looking at climate data over the past century has concluded that solar variation has made a significant impact on the Earth’s climate.  The report concludes that evidence for climate changes based on solar radiation can be traced back as far as the Industrial Revolution.

Past research has shown that the sun goes through eleven year cycles.  At the cycle’s peak, solar activity occurring near sunspots is particularly intense, basking the Earth in solar heat.

But don’t get too excited, because there is no way that a government-run agency is going to give back money to the taxpayer by hinting that there is no such thing as man-made global warming, regardless of scientific evidence.

While the NASA study acknowledged the sun’s influence on warming and cooling patterns, it then went badly off the tracks.  Ignoring its own evidence, it returned to an argument that man had replaced the sun as the cause current warming patterns.  Like many studies, this conclusion was based less on hard data and more on questionable correlations and inaccurate modeling techniques.

Don’t forget to read my recent post which contains quotations from real environmentalists.

Are the oceans warming?

6 Comments

We actually have a pretty comprehensive way of measuring the changes in the temperature of the oceans. We use a submersible sensor called an “Argo Buoy” in order to do the measurements. Since 2003, 3000 of them have been taking measurements in all the oceans of the world. The purpose of the buoys is to provide scientists with confirmation that the globe is really warming. But all was not well.

But the Vancouver Sun reports: (H/T Commenter ECM)

So why are some scientists now beginning to question the buoys’ findings? Because in five years the little blighters have failed to detect any global warming. They are not reinforcing the scientific orthodoxy of the day, namely that man is causing the planet to warm dangerously. They are not proving the predetermined conclusions of their human masters. Therefore they, and not their masters’ hypotheses, must be wrong.

In fact, “there has been a very slight cooling,” according to a U.S. National Public Radio (NPR) interview with Josh Willis at NASA’s Jet Propulsion Laboratory, a scientist who keeps close watch on the Argo findings.

Well, maybe the climate models predicted some cooling?

The big problem with the Argo findings is that all the major climate computer models postulate that as much as 80-90 per cent of global warming will result from the oceans warming rapidly then releasing their heat into the atmosphere.

But surely the other models are being confirmed by observations?

Modellers are also perplexed by the findings of NASA’s eight weather satellites that take more than 300,000 temperature readings daily over the entire surface of the Earth, versus approximately 7,000 random readings from Earth stations.

In nearly 30 years of operation, the satellites have discovered a warming trend of just 0.14 C per decade, less than the models and well within the natural range of temperature variation.

But maybe if we wait for a while, scientists will discover new measurements that are the opposite of these measurements. The new measurements will confirm that global warming is real, that scientists need more grant money, and that socialists must take control of the economy right now in order to save us from the horrible Flying Spaghetti Global Warming Monster! Those 700 dissenting scientists? Paid off by big oil! All of them!

The polar ice caps were also paid off by big oil. How else do you explain their refusal to melt?

UPDATE: NASA study shows that solar activity is responsible for past global warming.
