It was further demonstrated that TI could be used to discriminate between an increase in atmospheric thermal inertia (greenhouse effect) and an increase in input energy. This property was used to demonstrate that the warming trend between 1973 and 1994 was due to increases in input energy and not increases in thermal inertia. There was no significant correlation between the rise in CO2 and the TI metric.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-36333052.post-52388761280156206422007-05-22T05:19:00.000+10:002007-05-22T05:19:00.000+10:00I'll summarize what Jonathan's analyses show.Dayti...I'll summarize what Jonathan's analyses show.<BR/><BR/>Daytime temperatures are increasing relative to nighttime temperatures, and changes to maximum and minimum temperatures reflect increasing daytime temperatures and do not reflect a more or less compensating increase in nighttime cooling. <BR/><BR/>Mean temperature calculated (as it is) from the average of maximum and minimum is giving a misleading indication of warming in the sense of heat gain.<BR/><BR/>As the to the cause (assuming a single cause), it can only be the atmosphere is allowing increased incoming and outgoing radiation (i.e. it's not solar).<BR/><BR/>I'd also like to see whether the time of the daily minimum and maximum temps have changed. In addition, I'd like to see if places like China where atmospheric particulates have increased show similar trends.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-36333052.post-30746892935593346622007-05-21T22:56:00.000+10:002007-05-21T22:56:00.000+10:00I am wondering if you can extend on your comments ...I am wondering if you can extend on your comments in a post about a link between an increase in day time temperatures and solar influence.

I'm not quite sure that i actually meant that and will delete that little spiel. temperatures around 3pm are hotter than at 9am in tropical nth qld, but have not seen an increase at that time over time. there is still a significant increase from 9am as opposed to 6am and a significant decrease at 6pm from 3pm which still indicates the suns influence.Jonathan Lowehttps://www.blogger.com/profile/13972477779077598483noreply@blogger.comtag:blogger.com,1999:blog-36333052.post-27833078531300836842007-05-21T12:13:00.000+10:002007-05-21T12:13:00.000+10:00One more thing... space-based observations of the ...One more thing... space-based observations of the total solar irradiance show a downward trend (modulated by the 11-year activity cycle) since the measurements began in 1978. This trend exceeds the instrumental uncertainty.<BR/><BR/>While the solar effect on climate is well-established from paleoclimate studies, it would seem that if solar radiation was the zeroth order forcing then we'd have seen a decrease in global mean temperature since '78. Unless there was some other important forcing...Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-36333052.post-84427314713546533192007-05-21T12:04:00.000+10:002007-05-21T12:04:00.000+10:00You say that 9am was the only series with a signif...You say that 9am was the only series with a significant rise and attribute this to the maximum temperatures being early in the day (i.e. 9am is warmer than 3pm). Since the mean temperatures at 3pm (9am) are typically -using Gyndah as my example- ~30 (26) in summer and ~22 (15) in winter, it seems that this would actually need looking at before you can claim it.<BR/><BR/>Is 9am consistently warmer than 3pm across the Queensland stations?<BR/><BR/>I'd like to see a plot of (time of peak temperature) against (year) for, say, January and July. If you're right, then the plots should start with the 3pm bin showing the peak temperature most often and move (as the years pass) to the peak being observed at 9am.<BR/><BR/>(You may also need to treat the tropical and sub-tropical stations differently)Anonymousnoreply@blogger.com
