Climate change alters the ecological impacts of seasons

[font size=4]Max Planck paper observes temperature variability across the world[/font]
October 08, 2014
[font size=4]If more of the world’s climate becomes like that in tropical zones, it could potentially affect crops, insects, malaria transmission, and even confuse migration patterns of birds and mammals worldwide. George Wang, a postdoctoral fellow at the Max Planck Institute for Developmental Biology in Tübingen, Germany, is part of a research tandem that has found that the daily and nightly differences in temperatures worldwide are fast approaching yearly differences between summer and winter temperatures.[/font]
[font size=3]…
The research was “very computationally intensive”, as Michael Dillon points out. The researchers had to use computer clusters on two continents, with the majority of the work performed on the cluster at the MPI for Developmental Biology. They also used a new mathematical technique to describe how temperature changes from day to night, and winter to summer, thus characterizing the variability of temperature over the globe.
According to this, the changes have been most dramatic for places closest to the poles and far from oceans. “In these places, warmer winters -- decreasing the difference between summer and winter -- and hotter days -- increasing the difference between day and night -- mean that the range of temperatures, which organisms experience over a few days, is closer to the range of temperatures they experience over an entire year. These patterns are strongest in Canada and Russia, but occur even in Germany,” explains Wang. “For example, in Wiesbaden, in 1992, the average difference between day and night was 1.2 degrees, while the average difference between summer and winter was 24.8 degrees. In 2012, the day/night cycle was 5.2 degrees, while the summer/winter cycle was 18.9, so the daily temperature variability is now much more similar to the yearly variability. Compare this to Las Palmas in the Canary Islands, where the day/night difference is about 4.3 degrees and the summer/winter difference is about 6.7 -- it has not changed very much.”
…
The findings show that no place is safe from climate change. “Most people are rightly concerned about sea level rise, but feel that this will not affect them if they don't live next to the ocean. We find that places far from the oceans will have be biggest changes in daily and seasonal temperature variability, because they are far away from the buffering effects of oceans”, says Wang. Therefore, there would be no places immune from effects of climate change, and this would have consequences on crops, parasites, and disease.[/font][/font]

If you're like me, I'll bet you discover that the morning lows are much much higher than 1 or 2 degrees above average shown in most global studies. Here it's typical they're between 7 - 15 degrees above normal and we're seeing more frequent mornings where there's so much trapped heat in the air, it's not uncommon for it to be higher than that. Some days it's less than 7 degrees above normal, but around 7 seems to be fairly typical, with periods of 10 - 15 above normal.
I wish someone would study the morning low temps instead of the daily high temps. It would seem to be a better marker for understanding what is in our atmosphere that is trapping heat and preventing it from naturally escaping out into space.
