Do you think global warming has slowed or stalled?

Question

Some people have argued that global warming has slowed or stalled because we haven't had a year hotter than 1998.

However, the average temperature this decade has been 14.531 deg. C. The average temperature in the 1990s was 14.3206 deg. C. The average temperature in the 1980s was 14.1685 deg. C. Not only is this decade warmer than the 90s (by 0.21 deg. C), but it's a bigger difference than the warming from the 80s to the 90s (0.152 deg. C).

Plus with the exception of 1998, every year 2001-Present has been warmer than every year in the 1990s (and every previous year on record).

Considering all this information, do you think global warming has slowed or stalled?

Ron C - when you lie about what others have claimed, it eliminates any credibility you had remaining.

This data is from Trevor's website. Clearly it illustrates that global warming is accelerating.

Answer 1

Global warming is a climate change issue. The weather in 2007 does not indicate what the climate average temperature for 2007 will be. A moving average is a more appropriate measure and the shortest meaningful window is 5 years. On this basis, the 5 year climate temperature for 2005 is the average of the years 2003, 2004, 2005, 2006 and 2007. The 5 year averages can be calculated in like manner for years between 1852 and 2005. The rate of change in the temperature increases can be calculated by subtracting the mean value for 2004 from the mean value for 2005 and so on. I manually entered the values from 1959 to 2007 and arrived at the following conclusion: The best fit to the 5 year mean climate temperature is a quadratic y=0.311x^2 - 1219.3x + 1.95E6, R^2 = 0.97. The rate of change and acceleration are the first and second derivatives of this equation yielding 27.8 +- .7 mK/yr and 0.6 +- 0.4 mK/yr^2, respectively. If a linear equation is used the fit is R^2 = 0.92 with an average slope of 14.8 (7) mK/yr. If the backward difference rather than the curve fit is used to calculate the acceleration, the result is 0.7 (4) mK/yr^2. Up to 2005 the data clearly show that global warming is continuing and accelerating. I don't know what the result for 2007 will be. Ask me in 2009 when the data is available to calculate a meaningful average. For 2007, I will observe that the climate responds to physical forcings related to solar insolation, albedo, greenhouse gasses, etc. which have not changed much in the last 2 years. On this basis I would expect the trend to continue, but await the data. (note temperature units are milli-Kelvins)

Answer 2

Check the record highs in 1936! They far exceed the 1990's.
Then of course we had the 1970's where everyone was screaming about global cooling from a scientist bought by the big oil companys!

Check with the IPCC author Prof.Christy who debunks the whole global warming theory as a swindle. It is a big money maker.

You then again may want to check with NASA's top climatologist Roy W. Spencer and he will concur the theory is propaganda.
or there is:

Tim Ball of Winnepeg

Dr. Shaviv, Israel

Dr. Reiter, Paris

Prof. Clark, Blaby

Dr. Lindzen, M.I.T.

The top climatologists around the world find the theory terribly flawed. the explanation is the approximate 500 year cycles.

There are many others around the world that are in the top of their field that state global warming is not a man made occurance, it is natural and in about 15,000 years it is predicted that we will have another ice age.

"MERRY CHRISTMAS!"

Answer 3

Yes, the rate of increase slowed dramatically after 1998. Even Trevor admits we are in a period of no warming.

A recent peer-reviewed paper by alarmists claims that "internal variability will partially offset the anthropogenic global warming signal for the next few years. However, climate will continue to warm, with at least half of the years after 2009 predicted to exceed the warmest year currently on record.” Even the alarmists expect 2008 to be cooler than 2007, which was cooler than 2006.

You can read about the paper and Roger Pielke's view of it here.

The prediction that warming will kick in after 2009 is a prediction I have no confidence in. The internal variability (meaning mainly the PDO) has only just turned to the cool phase part way through 2007. I expect to see cooler temps for the next 30 years.

Answer 4

ARe you impervious to the fact that we had an unprecedented SNOWFALL< and that the shoreline of GREENALND< North and South POLES have dwindled! There has been a HUGE INCREASE in the amount of HUMIDITY and water in the air, HENCE the excessive SNOWFALL! AUSTRALIA has had unprecedented HEAT SPEELS at about 122 degrees F! I make fun of GLOBAL WARMING a bit myself, but the CLUES are everywhere that SOMETHING IS W+RONG! It is NOT our fault, and I believe that real GEOLOGISTS will tell you that earth history shows that MAJOR CLMITAE CHANGES occur every 30,000-40,000 years! Also that the earth has had a few POLAR REVERSALS in it's history! Perhpas THIS is what killed the dinosaurs and muchmajor plant life! Insects will outlive us ALL< and new forms of illnesses appear EVERYWHERE every day, even in CATS and DOGS! TEMPERATURE CHANGES affect the biol balances, and the lifestyles off BACTERIA and FUNGI and VIRUSES we all sauffer from! I am recovering from a devastating round of BED BUGS< not seen since the forties! JUSTLOOK AROUND at all the snow! this water (SNOW) came formt he oceansa, did it not! EVAPORATED OCEAN WATER that has turned into a ner DEADLY snowfall with falling temps in teh NORTHERN HEMISPEHERE< and devastating HEATWAVES in the southern hemisphere! GEOLOGIACL CHANGES are PREDICTABLE in may ways thansk to the latest in scientific instrumentation, and further detailed examinatinos of our earth's past in archeological discovery as well! <<<>>>>!

Answer 5

Of course it hasn't stalled! What you're talking about there (average temp for an entire year) is called climate, and the AGW theory is a "climate" change theory, not a weather change theory. When people come on here and talk about how it's so cold outside and therefore global warming must be stalled, they really don't know what they're talking about.

Good luck trying to convince them though!

Answer 6

OK, Master of Science, I think your data is flawed. SERIOUSLY flawed. How is this decade's average temperature warmer than the last, if the individual years have been cooler? That doesn't really seem to make sense.

As this last link states, warming will likely continue, despite our momentary cooling trend, but this very same trend points rather obviously to that, as anthropogenic CO2 concentrations are growing ever higher while temperature is dropping, humans aren't the main cause of warming. (Meanwhile, the sun is going through a cooler cycle just as the earth is. A coincidence? Distorted data? I think not.)

Answer 7

ALL profend.com shows is that we are coming out of what is know as the Little Ice Age.

that is all that global warming is a natural end of a ice age.
http://en.wikipedia.org/wiki/Little_Ice_Age

even if there had been no change in CO2 levels this would have happened.

Answer 8

Well its Christmas now ,nothing happens anywhere.

The people causing Global Warming are to busy having Christmas parties right now .

Just kidding

Answer 9

I agree with Light W.Global warming is a fantasy.The earth goes through all sorts of weather changes and everyone panics.I live in New England,and it's freezing,and all it does is snow.Does that sound like global warming?All these bored people just want something to be concerned about.Al gore is full of it.The planet is fine...it's the people that are f..ked !

Answer 10

well some people dont care but it is nice of you to care, many people recycle so that things can be used again plant trees try not using cars some factories are doing something to try to stop pollution that comes out of their factories. There are many thing that you can do to help but the problem is that about I dont know 15% dont care, we cause pollution and it depends on us to stop it.
