Carter Marine Geophysical Laboratory, James Cook University, Townsville, Queensland, Australia Time series for the Southern Oscillation Index (SOI) and global tropospheric temperature anomalies (GTTA) are compared for the 1958?2008 period. GTTA are represented by data from satellite microwave sensing units (MSU) for the period 1980-2008 and from radiosondes (RATPAC) for 1958-2008. After the removal from the data set of short periods of temperature perturbation that relate to near-equator volcanic eruption, we use derivatives to document the presence of a 5- to 7-month delayed close relationship between SOI and GTTA. Change in SOI accounts for 72% of the variance in GTTA for the 29-year-long MSU record and 68% of the variance in GTTA for the longer 50-year RATPAC record. Because El Niño?Southern Oscillation is known to exercise a particularly strong influence in the tropics, we also compared the SOI with tropical temperature anomalies between 20°S and 20°N. The results showed that SOI accounted for 81% of the variance in tropospheric temperature anomalies in the tropics. Overall the results suggest that the Southern Oscillation exercises a consistently dominant influence on mean global temperature, with a maximum effect in the tropics, except for periods when equatorial volcanism causes ad hoc cooling. That mean global tropospheric temperature has for the last 50 years fallen and risen in close accord with the SOI of 5-7 months earlier shows the potential of natural forcing mechanisms to account for most of the temperature variation.

It loses some of its ability to absorb CO2 as it warms up yes. If the temperature remains above a certain level, you will get an excess release of CO2 from the oceans some 800 years later, as the flush out deep ocean sediment. Shrug. I have been telling people that this is (global warming) pure kiddology for two decades. Perhaps the world is catching up with me again. Haven't you changed your tune a bit though recently? I'm pretty sure not so long ago you were denying utterly that any warming was taking place. http://tinyurl.com/n9x9m6 Now you've shifted your ground to conceding that it's real, but that it's some kind of natural phenomenon that you can't explain. And also, that it's mysteriously disappeared (which you also can't explain). [snip boasting about iraq] Same deal here. It is getting COLDER again. I still don't know how you can say that, given that the top ten hottest years have all been in the last 12. http://tinyurl.com/mtdcdr That worries me.

And since we don't have any nukes, it might ge awful nippy in the mornings hey? Ice ages are caused by major geological events, like the formation of new mountain ranges, or they're caused by changes in the Earth's orbit, or extreme variations in solar output. Are you saying that one of these has occurred and scientists haven't noticed?

some kind of natural phenomenon that you can't explain. And also, that it's mysteriously disappeared (which you also can't explain). And nor can the climate models that are used as the basis of the AGW scare campaign. Big difference is that I don't claim to have an accurate computer model of climate change which doesn't in any way match reality, and nor am I using these clearly and demonstrably incorrect models to demand huge changes to how the world works. Fact is, the climate warms and cools. Not one of the climate models predicts cooling, ever, none of them can explain the natural variability. There is no model which even vaguely manages to "predict" the climate changes that have occurred in the past. Given the models have repeatedly been proved wrong, why would anybody believe they can predict the future if they cannot even predict the past? You would have to be stupid to believe in a climate model which is demonstrably wrong. |

It's simple: There is not enough money being taken out of everyone's electric bill to properly stop AGW. Simple. Plausible. and lies. |

But selectively drawing lines from 1998 to 2008, for instance, doesn't really shine a light on anything except their own bias. Nor does narrowing down the sample from 2005 to 2008. -- "Conservatives are not necessarily stupid, but most stupid people are conservatives."- John Stuart Mill http://regruntled.wordpress.com/ |
