I do read the Curry et al (2006) paper you are refering to and at the page 1028 (right top), you wrote: the satellite - derived dataset of WHCC showed a global increased in
the number of category 4 and 5 hurricanes since 1970; I would love to know where you found the satellite data from 1970 and who has done the reanalysis in your team?
Our involvement in the issue of hurricanes and global warming began when we published an article in Science shortly before the landfall of Hurricane Rita, where we reported a doubling of
the number of category 4 and 5 hurricanes globally since 1970.
However, Emanuel (2005a) and Webster et al. (2005, 2006) indicated that the typhoons have become more intense in this region, with almost a doubling of PDI values since the 1950s and an increase of about 30 % in
the number of category 4 and 5 storms from 1990 to 2004 compared with 1975 to 1989.

Category 4 storm.
But a reduction in the
number and intensity
of large hurricanes driving ocean waters on shore — such as this month's Hurricane Joaquin, seen, which reached
category 4 strength — may also play a role by cooling sea - surface temperatures that fuel the growth
of these monster storms, the team notes.
The major storms, the

These relationships have been reinforced by findings
of a large increase in

4 - outcome exclusively non-behavioural (physical, chemical and other measurable parameters including weight, height, death, presence / absence,
number of individuals, etc...).

At the end
of their comment # 27 the authors state «Turning to very important question
of the frequency
of the strongest storms, it is entirely possible that a large increase in
category 4 - 5 storms will result from increasing greenhouse gases, despite an overall reduction in hurricane
numbers.
Another question we must ask is: will greater
numbers of hurricanes
of Category 4 or 5 strength make landfall as a result
of climate change (due to SSTs warming along with, but at a slower rate and with some time lag as, the atmosphere)?
Although the overall
number of storms in the region are expected to drop, the

There has been a substantial increase in most measures
of Atlantic hurricane activity since the early 1980s, the period during which high quality satellite data are available.20, 21,22 These include measures

number of strongest (
Category 4 and 5) storms.
Worldwide there will likely be an average increase in the maximum wind speed
of tropical cyclones (hurricanes and typhoons)
of 2 to 11 %.6 Because
of the way extremes respond to changes such as these,

number by the end

The U.S. National Climate Assessment finds that there has been a substantial increase — in intensity, frequency, and duration as well as the

Others there also tried to make clear the point that the line drawn between a «5» and a «
