Nasa/University of Colorado establish Sun-Climate Research Center

November 30, 2010

The “settled science” of climate change seems to be opening up to real science  – at last. Nasa and the University of Colorado are establishing a new research centre dedicated to studying the effect of the sun on climate.

And about time too.

Perhaps they could let the 15,000 gathered in Cancun know about the importance the Sun may have!

Today the University of Colorado Laboratory for Atmospheric and Space Physics (LASP) and NASA’s Goddard Space Flight Center announced the formation of a new collaborative research center dedicated to the study of the Sun’s effect on Earth’s climate. The Press release goes on to say:

The center, called the Sun-Climate Research Center (SCRC), will be directed by Peter Pilewskie, a LASP research scientist and CU professor, Robert Cahalan, Head of Goddard’s Climate and Radiation Branch, and Douglas Rabin, Head of Goddard’s Solar Physics Laboratory.

Pilewskie said, “The exciting thing about this collaboration is that we believe it will promote studies to help answer a key question about the climate system: how does Earth’s atmosphere respond to the sun’s variability, and how does that affect climate? This question is particularly important now, as we seek to quantify the human-induced impact on Earth’s climate.”

The SCRC, which has been made possible by a Federal Space Act Agreement, will foster collaboration between Earth-atmosphere and solar sciences at the two institutions. Opportunities will include a scientist exchange program between the organizations, the ability for post-doctoral scientists and graduate students in science, engineering, and mission operations to move between LASP and Goddard, annual international Sun-Climate research symposia, and the ability for the two institutions to collaborate more fluidly on future research opportunities.

Robert Cahalan, SCRC co-director and Goddard scientist, said, “In recent years Goddard and LASP have worked together on several Earth and Sun missions. Now we look forward to continuing to drive growth in this key interdisciplinary field of Sun-Earth research, bringing new focus to the study of multiyear changes in the Sun and their influence on Earth’s climate.”

With a limited number of such agreements between U.S. universities and any of NASA’s ten field centers, the SCRC represents a rare and innovative step, underscoring LASP’s ability to develop high-caliber research and programmatic opportunities with Goddard.

Daniel Baker, LASP Director, said, “LASP has developed some remarkable areas of expertise that are key to studying the sun and its effect on climate and on human activities. By working with our colleagues at Goddard, we can leverage our skills—and help take an important step toward greater cooperation between NASA centers and leading university research teams.”

Unsettled science?

History of sunspot number observations showing...

Within the space of two days there have been two scientific papers with entirely different conclusions about the effect of the active sun on climate. That there is a difference from two different studies is perfectly normal (and desirable if we are to learn), but what is obvious is the inanity of considering that the effects of solar variations on climate is a “settled science”. Solar Science and Climate are still in the realm of “where we don’t know what we don’t know”.

The first on October 5th, led to the conclusion that:

an increase in solar activity from the Sun actually cools the Earth

The second reported here comes to the conclusion that:

“The contribution of the active sun, indirectly via cosmic rays, to global warming appears to be much stronger than the presently accepted [IPCC] upper limit of 1/3.”

The Sun moves to its own music

October 6, 2010

Totally impervious to vulgar 10:10 videos, biodiversity 10.10 campaigns, 0% interest rates and other goings-on on Earth, the Sun moves to its own music.

It was spotless again.

Sunspot numbers and 10.7 flux continue to be significantly lower than forecast (and the forecast for Cycle 24 were pretty low to begin with).

2010/10/05 08:00 Today was spotless although Locarno managed to see two groups. The specks were tiny and would be on the fringe of visibility on the original Wolf 64x telescope on a perfect day. What could be old area 1106 may be returning in the next two days.

Yesterday’s adjusted F10.7 flux figures recorded a high of 76.6 (81.4) and a low of 74.7 (78.8), unbelievably low.

F10.7 Radio Flux (including September 2010)

That we are in a solar minimum (the Landscheidt minimum) seems clear but whether it will be a grand minimum remains to be seen.

And the sun will surely impact our climate — but how?

And in any case the sun gets no feedback and it does not much care.


Most detailed image of a sunspot ever by Big Bear

August 27, 2010

No wonder sunflowers are obsessed !!

Researchers at Big Bear Solar Observatory have tuned their adaptive optics array and achieved first light, capturing this image of a sunspot that is now the most detailed ever captured in visible light. The image was captured with Big Bear’s New Solar Telescope (NST), a brand new instrument (as the name implies) with a resolution of just 50 miles on the sun’s surface.

The NST is the precursor to an even-larger telescope, the Advanced Technology Solar Telescope (ATST), which will be constructed over the next decade, allowing Big Bear researchers to build a new kind of adaptive optics system known as multi-conjugate adaptive optics, that should provide them with a clear, distortion-free means of observing the sun from Earth in unrivaled detail.
