Global climate change … NASA’s eyes on the Earth: A warming world – global temperature update … piecing together the temperature puzzle.

Each year, scientists at NASA’S Goddard Institute for Space Studies analyze global temperature data. The past year, 2009, tied as the second warmest year since global instrumental temperature records began 130 years ago. Worldwide, the mean temperature was 0.57°C (1.03°F) warmer than the 1951-1980 base period. And January 2000 to December 2009 came out as the warmest decade on record.

2009 was tied for the second warmest year in the modern record, a new NASA analysis of global surface temperature shows. The analysis, conducted by the Goddard Institute for Space Studies (GISS) in New York City, also shows that in the Southern Hemisphere, 2009 was the warmest year since modern records began in 1880.

Although 2008 was the coolest year of the decade, due to strong cooling of the tropical Pacific Ocean, 2009 saw a return to near-record global temperatures. The past year was only a fraction of a degree cooler than 2005, the warmest year on record, and tied with a cluster of other years — 1998, 2002, 2003, 2006 and 2007 1998 and 2007 — as the second warmest year since recordkeeping began.

“There’s always an interest in the annual temperature numbers and on a given year’s ranking, but usually that misses the point,” said James Hansen, the director of GISS. “There’s substantial year-to-year variability of global temperature caused by the tropical El Niño-La Niña cycle. But when we average temperature over five or ten years to minimize that variability, we find that Global Warming is continuing unabated.”

January 2000 to December 2009 was the warmest decade on record. Throughout the last three decades, the GISS surface temperature record shows an upward trend of about 0.2°C (0.36°F) per decade. Since 1880, the year that modern scientific instrumentation became available to monitor temperatures precisely, a clear warming trend is present, though there was a leveling off between the 1940s and 1970s.

The near-record temperatures of 2009 occurred despite an unseasonably cool December in much of North America. High air pressures in the Arctic decreased the east-west flow of the jet stream, while also increasing its tendency to blow from north to south and draw cold air southward from the Arctic. This resulted in an unusual effect that caused frigid air from the Arctic to rush into North America and warmer mid-latitude air to shift toward the north.

“Of course, the contiguous 48 states cover only 1.5 percent of the world area, so the U.S. temperature does not affect the global temperature much,’ said Hansen. In total, average global temperatures have increased by about 0.8°C (1.5°F) since 1880.

“That’s the important number to keep in mind,” said Gavin Schmidt, another GISS climatologist. “In contrast, the difference between, say, the second and sixth warmest years is trivial since the known uncertainty — or noise — in the temperature measurement is larger than some of the differences between the warmest years.”

Decoding the Temperature Record: Climate scientists agree that rising levels of carbon dioxide and other greenhouse gases trap incoming heat near the surface of the Earth and are the key factors causing the rise in temperatures since 1880, but these gases are not the only factors that can impact global temperatures.

The Most Terrifying Video You’ll Ever See

Posted by admin on April 24, 2012 in Global Warming with 24 Comments

Over 8 million total views. Now there’s a book:
“…superbly crafted…A must read.” -Gen. Anthony Zinni, US CENTCOM Commander (Ret.)

“This book trumps most of our accounts of the Global Warming crisis.” –author Bill McKibben

“Al Gore should share his Nobel peace prize.” -The “New Scientist”

“This is a tremendous book and well worth anyone’s time to read…. You’re in for a treat—Craven is funny as well as exceptionally clear, and wise.” –Kim Stanley Robinson, Hugo and Nebula Award-winning author of the Mars Trilogy and Science in the Capital

“This is a terrifically thoughtful book…. Cravens book shines an illuminating floodlight on how we think about global warming.”
–Ross Gelbspan, author, “The Heat Is On” and “Boiling Point”

Greg Craven (that’s me!), the creator of “The Most Terrifying Video” never intended to write a book. It just sort of happened. All as a result of the two-year back-and forth I’ve had with the YouTube community about this video and its follow up marathon “How It All Ends.”

So now “What’s the Worst That Could Happen? A Rational Response to the Climate Change Debate” is available from Amazon and other sellers through the links at www.gregcraven.org, as well as your local bookstore (I hope!).

Check it out if you’re intrigued by the argument in this video.

THE REASON THE COMMENTS ARE CLOSED ON THIS VIDEO is that most of the criticisms of what’s presented here have been addressed by the bruisingly thorough 7-hour How It All Ends video project, the discussion is happening over there. I spent months combing through literally tens of thousands of critical comments to find every single objection, criticism, “Yeah but,” and “You missed a spot” that I could to this video.

You might find the results interesting, and hopefully, helpful: http://www.youtube.com/view_play_list?p=92EE5DBE2987982F

You can post comments there. But to tell the truth, the conversation has moved even farther along, since the criticisms to those videos gave rise to the book, which now has its own discussions going at http://www.manpollo.org/forums/index.php.
