"Update Jan 24, 2008: RSS TLT change in response to discrete error notice: January 16, 2008

We discovered an error in our processing of AMSU data from NOAA-15 for TLT. A new version, version 3.1 is now available and should be used for all applications. This new version
is in much better agreement with other sources of tropospheric temperature. We apologize for any inconvenience.

What was the error?

Last January, I made a small change in the way TLT is calculated that reduced the absolute Temperatures by 0.1K. But I only used the new method for 2007 (the error). When the data are merged with MSU, MSU and AMSU are forced to be as close as possible to each other over the 1999-2004 period of overlap. This caused the error to show up as a downward jump in January 2007. To fix the problem, I reprocessed the 1998-2006 AMSU data using the new code (like I should have done in the first place), and merged it with the MSU data.

We would like to thank John Christy and Roy Spencer, who were very helpful during the diagnosis process.

Hr eru tu mtur um hnattrna hlnunn eftir Prfessor R M Carter

Myth 1 Average global temperature (AGT) has increased over the last few years.
Fact 1 AGT has remained steady, or slightly declined, since 1998.
Myth 2 During the late 20th Century, AGT increased at a dangerously fast rate and reached a high point of unprecedented magnitude.
Facts 2 The recent rate of AGT rise has been between 1 and 2 deg. C/century, which falls squarely within natural rates of climate change for the last 10,000
years. AGT has been several degrees warmer than today many times in the recent geological past.
Myth 3 AGT was relatively unchanging in pre-industrial times, has sky-rocketed since 1900, and will increase by several degrees more over the next 100 years (the Mann, Bradley & Hughes "hockey stick" curve).
Facts 3 The Mann et al. curve has been exposed as a statistical contrivance. There is no convincing empirical evidence that past climate was unchanging, nor that 20th century changes in AGT were unusual or unnatural.
Myth 4 Computer models predict AGT will increase by 6 deg. C or more over the next 100 yr. Facts 4 Deterministic computer models do. Other equally valid (empirical) computer models predict cooling.
Myth 5 Warming of 1-2 deg. C will have catastrophic effects on ecosystems and mankind alike.
Facts 5 Ecosystems have been adapting to climate change since time immemorial. The result is the process that we call evolution. Mankind can adapt to all climate extremes.
Myth 6 Human addition of carbon dioxide to the atmosphere is causing dangerous warming, and is generally harmful. Facts 6 No human-caused warming can yet be detected that is distinct from natural system variation and noise. Any additional human-caused warming which
occurs will probably amount to less than 1 deg. C. Atmospheric carbon dioxide is a beneficial fertilizer for plants, including cereal crops, and also aids efficient evapo-transpiration.
Myth 7 Changes in solar radiation cannot explain recent changes in AGT. Facts 7 The sun's output varies on many time scales (including that of the 11-year sunspot cycle), with concomitant effects on Earth's climate. More than 50% of the 0.8 deg. C rise in AGT observed during the 20th century can be attributed to solar change. Myth 8 Unprecedented melting of ice is taking place in both the north and south polar regions.

Facts 8 Both the Greenland and Antarctic ice sheets are growing in thickness. Sea ice around Antarctica is growing. Temperature is falling at the South Pole.
Temperature in the Arctic Ocean region is just now achieving the levels of warmth experienced during the early 1940s, and the region was warmer still (sea-ice free) during earlier times.

Myth 9 Human-caused global warming is causing dangerous global sea-level (SL) rise.

Facts 9 SL change differs from time to time and place to place; between 1955 and 1996, for example, SL at Tuvalu fell by 105 mm (2.5 mm/yr). Global average
SL is a statistical measure of no value for planning purposes. The global average SL rise of 1-2 mm/yr that has occurred over the last 200 years shows little sign of increasing.
Myth 10 An increase in AGT during the late 20th century has led to an increase in the number of severe storms (cyclones) or in storm intensity.
Facts 10 Meteorological experts are agreed that no increase in storms has occurred beyond that associated with natural variation of the climate system. The
argument that storms have increased in their intensity as a result of warming remains the subject of strong dispute.

Froele
10 January 2008 Before I read this article I was, like all of my friends, convinced that the world was continuing to warm ever upward (I had been watching the BBC and believed it). However as a result of this article I took a look at the data myself and I feel deceived. Whatever the reason the world's temp has not increased for 7 years, why wasn't I told that by any of the science 'correspondents' who told me about global warming? Looking at this comment thread I see there are some people who can't stand that the temperature has been unchanged for the past 7 years - and they have to do 'statistics' to show that It's all right really the world really is warming as it should be it's just that the measurements don't reflect what is really going on! Seems to me Dr Whitehouse is right because he has stuck to the data and simply described the data. To them I say, I am taking the spirit of the article, the measurements say it's flat, so it's flat until it does otherwise and I don't think anyone knows if it will stay the same or go up and down. As it is my once unquestioning faith in the man made greenhouse gases causing global warming has been shaken. Perhaps that channel 4 programme on the global warming swindle had a germ of truth in it after all. I began to suspect that it might by the over the top reaction to it by some activists - I can't remember the name of the dope who organised a petition to offcom I think but he seems so manic that i wondered if he doth protest too much. Dr Whitehouse's article has shattered a big myth - I, and I suspect most people, believed that the world's tem was ever upward and each year was warmer than the past - now I see that this is not so. Dr Whitehouse says the flatlining of the temperature might be significant or it might not but 1. He was right to dispel the common misconception and 2. It might just be the most important science article written in decades if it turns out that the global temp does start going down again.

All we can do is wait and see.

Prfessorinn segir meal annars ar:

None of the existing global climate models have forecasted the apparent temperature break around 1998. On the contrary, they all forecast increasing temperatures along with the ongoing increase of atmospheric CO2. In a scientific context the present temperature break therefore is a classic example of what is known as empirical falsification, disproving the hypothesis on the dominant influence of CO2 and alleged associated effects on the global temperature. Clearly other factors since 1998 must have had a cooling effect of at least at the same magnitude as the alleged warming effect of greenhouse gasses. Consequently, global climate models apparently are still not perfect, and require modification and presumably also the inclusion of additional processes.
