[...] Niña is essentially the opposite of the warming pattern known as El Niño. Both are year-to-year phenomena related to ocean circulation in the tropical Pacific, and both [...]

It's so great to find a serious scientific take on this issue. People gossip about it all the time but nobody ever seems to come from a position of knowledge.

Good question. The trend in the diurnal temperature range, or in the lingo of climate scientists DTR, has been of intense interest to climate scientists. For many years the data appeared to indicate the DTR was decreasing; i.e., nighttime temperatures were increasing more rapidly then daytime temperatures. However, according to the most recent report of the Intergovernmental Panel on Climate Change "updated observations reveal that DTR has not changed from 1979 to 2004… (However), the trends are highly variable from one region to another."

Nice explanation of El Nino, Dr. Chameides.

On a (somewhat) related note, what impact do higher daily low temperatures have? Does the global data suggest that daily temperature ranges are contracting (ie, the difference between daily high and low temperatures)?

It seems like the cumulative effect of a shrinking temperature range would be at least as powerful as rising high temperatures (if not more). A lot more attention is given to high temperatures though.

Thanks for the explanation. I'm a meterologist (retired) and knew about El Nino's for awhile, but can see your point of looking at the bigger global picture regarding warming. El Nino's also tend to cause more precipitation which may be one reason some regions of the US are cooling slightly.

Is there any study that shows what the global temperatures would be without El Nino effects? If there would not have been El Nino in 1998, that year would not have been a record warm year, correct? 2005 would have been, is that right? Do you think an El Nino effect caused the heat in the 1930s as well? Does anyone have data on that?

Anyway, thanks. The next 3-5 years of temperature data will tell all I think. I just hope that data is not somehow altered/filtered to fit a specific long-term forecast trend.

This one comes up all the time in the blogs I hang out in, so thanks for the tip!
