My comprehensive study of Texas rain events of 20 + inches from 1948 - 2002 found
no overall change in frequency over the period.

Rather than look at the
overall number of DNA
changes, Harris focused on the
frequency of
changes in each kind of DNA base
in the populations she studied.
Analysis of 166 stars found almost a quarter — much more than expected — had small, rocky planets, which should force a
change in thinking on the
overall frequency of such bodies.
I find the entire concept of attempting to partially attribute cyclone power or
frequency of specific storms to climate
change wanting,
in light of the fact that the
overall numbers do not appear to demonstrate any trend.
-- Projected precipitation and temperature
changes imply
changes in floods, although
overall there is low confidence at the global scale regarding climate - driven
changes in magnitude or
frequency of river - related flooding, due to limited evidence and because the causes of regional
changes are complex.
But focusing the debate within societies on
overall frequency or intensity or degrees of this or that
in this or that geographical basin as a way to evaluate the relationship between climate
change and tropical storms is confusing the issue.
Mid-latitude storms have decreased
in frequency (e.g.,
in the United States
overall) while high - latitude storm activity has increased (e.g.,
in Canada).4 It is likely that human influence contributed to these
changes.5
The
overall result of the analysis is similar to the real - time analysis with a best estimate of a 59 % increase
in event
frequency, but a larger confidence interval that does include no
change.
