That is bull **** and YOU know it!
There are no other studies of diurnal asymmetry that show the same results as Karl et al. Davies et al. shows this.
Why do you insist on lying about this?
Now how would a study published in 1993 have data and show results for up to 2000?
:lamo
Clearly... you are making an argument based on a typo in the Davies study. And if you think I am wrong then explain how that works. Did Karl have a crystal ball that showed the future?
Yes... Hansen's statement stands in contrast to Karl et al. But not to all the other studies discussed in Davies. You know... all the other studies that you keep pretending don't exist in an effort to back up your biased beliefs.
Here is the table 1 from Davy,
Just for fun let's pull out the ones that say global and see what they show and their conclusions.
Karl et al. (1993) 1951–2000; Globe DTR,−0.14, T-Max 0.07, T-Min 0.21 , DTR is significantly reduced largely because of strong increase in Tmin in wintertime (December
through May) and in high latitude.
Braganza et al.(2003)1951–2000; Globe DTR,−0.07, T-Max 0.12, T-Min 0.19 No comment on conclusions in Table.
Vose et al. (2005) 1950–2004; Globe, DTR−0.07 a, T-Max 0.14 a, T-Min0.20a, DTR change is smaller after 1979 but strong increase in Tmin in wintertime continues.
Vose et al also has footnote a, which says, "
a The maximum change in December through February."
So even the study that T-Min was only 43% greater than T-Max, the increases in T-Max were in the winter months.
What we are left with is that the minimum temperatures are, and have been increasing faster than the maximum temperatures.
Of the observed increases in average temperature, the vast majority has been increases in minimum temperatures,
and some maximum temperatures in the winter months.
I have no doubt that limited weather events like El Ninos or Volcanic eruptions, can alter the ratio for a time, but the long term trend is
what climate is composed of!
