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.

    So all the pollution we pump out in the air is not doing anything? All the CO2 each year. Trillions of cubic tons is not affecting weather outside or anything? When the CO2 is out it's destroying our atmosphere and ozone layer which is making heat trapped in the planet warming it up. Each year temperatures slowly get warmer. May not be drastic as they say but it's happening. We are slowly destroying the earth.

  2. Rod Martin, Jr. says:

    NASA has lost all credibility on climate science. They tell just enough truth to make their lies seem palatable. Let's start with their "scientific consensus" page on their website. "Scientific consensus" is an oxymoron. "Consensus" is political, not scientific.

    Global Warming made civilization possible 12,000 years ago. Today's warming period is the weakest of the 10 warm periods of the Holocene. Combine that with the Little Ice Age, and it suggests that the Holocene may already be shutting down, starting 3,000 years ago.

    Look up "1816 – the year without a summer." When the Holocene does shut down, we'll end up with 90,000 years without summers, rain, crops, food, and civilization. Something to think about when NASA scientists go waving their arms saying how awful warming is. For Pete's Sake! We still live in an Ice Age. Melt the damned ice already and help people move. The alternative is 7 Billion dead and no civilization.

    They have only been measuring climate change since 1880 and the earth has been for millions of years.We believe that earth has evolved many times before man even existed on earth.Even if it was man made there's not much we or will about it.Will only make the richest people richer

    Now look at 2016. We're all going to die soon if we don't take actions.

    the people have the power to stop this. If everyone would come in agreement and be firm and not go work for these companies , they would not even exist. Simple don't go work for these companies the earth is more important then a job or money.

  9. Jeff Holt says:

    Now that corporations and banks are global in power and have been taking more and more global control international governments have concocted an idea of global warming to issue a carbon tax . The carbon tax is in reality a bullshit based study funded by government agencies to take more money from the corporations who they are currently competing with for global power. This made up scenario gives gangs of politicians a weapon of control over the gangs of international business people that run the planet. The study is funded by the governments who are trying to get leverage on the international business gangs.  Most governments are bankrupt on the planet and the international business men have bankrupted them. Its a weapon of power concocted through false scientific data funded by politicians. How else can politicians fight back against the corporations that create everything on the planet, including money.

    Can someone explain me how co2 is heating our planet? No one  on this damn youtube can not answer me? HOOOOOOWWWW?/??????

  14. Billy Staggs says:

    Global Warming / Cooling, Climate Change is all bullshit. At least the media sensationalized and politicized Climate Change is. It's all about money. Follow the money, people! Ever notice how it's cold… media will completely ignore any kind of cooling around the world, but when it's hot… the fear mongers, sheep and media is all over it, preaching "It's climate change, yadda, yadda, yadda." It's bullshit. The data that you see is bullshit to. It's a bunch of noise made to look like we're living in the hottest time ever.

    wanna end global warming? youtube bill mollison global gardener the dry lands. and greening the desert. 

    if your stuck in the city then youtube Ron Finley guerrilla gardener in L.A. add urben exploring, permaculture and john poole military tactics (applied to gardening just like sun tzu) 

    if you think government is the answer start pressuring the land management to stop killing the wild horses and selling them as dog food and instead restore the land like Joel Salatin (lunatic farmer)  making it a giant carbon sink in the great plains.

    the current economic model depends on growth. Without growth it simply collapses. China has to grow at an insane 7% per year to just to avoid social chaos. How do you stop a system that depends on the exploitation of finite resources and the burning of fossil fuels? you can't. This system is like a monster with a mind of its own, with so many complicated components that stoping it becomes almost impossible. The near future does not look good. Many of the effects of climate change cannot be stopped and it is already too late. The correct thing is the keep trying, but can you convince Shell oil to stop drilling and go out of business when the entire corporate model is to simply turn a profit at the end of the quarter? no way. Get ready for a rough ride in the next 20 years. Beyond that, survival of the fittest. (if survival is even possible) 

  17. Equs Narnd says:

    When future generations look back on the global-warming scare of the past 30 years, nothing will shock them more than the extent to which the official temperature records – on which the entire panic ultimately rested – were systematically “adjusted” to show the Earth as having warmed much more than the actual data justified.

    is this good science ,,,,,,

  20. Mikail Bölgen says:

    Is it really there is an global warming on earth or it is a pshygolocical war system within Nato and Varşova? Earth become sometimes to the timeline of ice age.?..Do we really go to other planet if this earth become a bad place…? if human being make love and more children from each if really earth become a hell place or it is a war thinking system in each human being to make other race do not make him or her a baby each other
