Yellowstone Journal: Are Yellowstone??™s ???Safety Valves??? Becoming Overloaded?

YOWUSA.COM, 02-November-2003
Dave Wright? 

Seismic and volcanic activities continue to escalate within our Earth as our sun continues to pound us with numerous solar flares, coronal mass ejections (CME), and charged particles of coronal holes.?  Given the current record-breaking solar activity, are Yellowstone??™s ???safety valves??? resilient enough to withstand this solar pounding while continuing to function properly??  The reason for this new concern is that Yellowstone??™s geysers (???safety valves???) appear to be working overtime to vent excess pressure, as evidenced by the recent behavior of the Steamboat Geyser.?  Steamboat is the largest geyser in the world!?  Unlike the anticipated eruptions of the 1980s, the most recent eruption was a surprise to geologists.?  To paraphrase the parlance of test pilots, is recent solar activity now pushing the edge of the Yellowstone envelope????

NASA STUDY FINDS INCREASING SOLAR TREND THAT CAN CHANGE CLIMATE

Since the late 1970s, the amount of solar radiation the sun emits, during times of quiet sunspot activity, has increased by nearly .05 percent per decade, according to a NASA funded study.

"This trend is important because, if sustained over many decades, it could cause significant climate change," said Richard Willson, a researcher affiliated with NASA's Goddard Institute for Space Studies and Columbia University's Earth Institute, New York. He is the lead author of the study recently published in Geophysical Research Letters.

"Historical records of solar activity indicate that solar radiation has been increasing since the late 19th century. If a trend, comparable to the one found in this study, persisted throughout the 20th century, it would have provided a significant component of the global warming the Intergovernmental Panel on Climate Change reports to have occurred over the past 100 years," he said.

Shrinking Arctic Sea Ice is Accelerating

Recently observed change in Arctic temperatures and sea ice cover may be a harbinger of global climate changes to come, according to a recent NASA study. Satellite data -- the unique view from space -- are allowing researchers to more clearly see Arctic changes and develop an improved understanding of the possible effect on climate worldwide.

The Arctic warming study, appearing in the November 1 issue of the American Meteorological Society's Journal of Climate, shows that compared to the 1980s, most of the Arctic warmed significantly over the last decade, with the biggest temperature increases occurring over North America.

"The new study is unique in that, previously, similar studies made use of data from very few points scattered in various parts of the Arctic region," said the study's author, Dr. Josefino C. Comiso, senior research scientist at NASA's Goddard Space Flight Center, Greenbelt, Md. "These results show the large spatial variability in the trends that only satellite data can provide." Comiso used surface temperatures taken from satellites between 1981 and 2001 in his study.

Scientists Comment on Solar Activity

A Lawrence Livermore National Laboratory scientist, in collaboration with an international team of colleagues, has reported that noticeable changes in the sub-polar climate and ecosystems appear to be linked to variations in the sun's intensity during the past 12,000 years.

Our results imply that small variations in solar irradiance induced pronounced cyclic changes in northern high-latitude environments. They also provide evidence that centennial-scale shifts in the Holocene climate were similar between the subpolar regions of the North Atlantic and North Pacific, possibly because of Sun-ocean-climate linkages.

The reconstruction shows reliably that the period of high solar activity during the last 60 years is unique throughout the past 1150 years.
