Climate alarmists claim
global warming is warming
the oceans, and that causes
more, and stronger,
hurricanes.
For all worldwide hurricane
landfalls since 1970, there
are no obvious trends.
But, If you sort the data
into weaker hurricanes
( category 1-2 )
and stronger hurricanes
( category 3-5 ),
there's a weakly
declining rate
of Cat 1-2 events,
and an increasing rate
of Cat 3-4-5 events.
Cat 1-2 landfalling events
dropped from around
11.5 a year in 1970 to
around 9.5 a year in 2020.
The Cat 3-5
landfalling events
increased from
about 3 a year,
to about 7 a year,
in the same period.
From 1970-1994
to 1995-2019,
the Cat 3-5s
have increased
by about 50% !
32.6%
of hurricanes
in the total
1970-2019
period
ended up
as Cat 3-5.
Many hurricanes
are near Florida
and Japan.
between July
and November.
A warmer
ocean temperature
could be the cause
of stronger storms.
The Atlantic Multidecadal
Oscillation moved into
a warm phase after 1995,
affecting Florida hurricanes,
but that could not explain
the similar trend near Japan.
The frequency of all Cat 1-5
hurricanes (cyclones)
globally hasn't
changed much
Ocean warming seems too small
to explain stronger hurricanes,
at least those near Florida
and Japan
The frequency of the stronger
Cat 3-5 hurricanes seems to be
increasing -- perhaps caused
by chance (random variations).
Merely blaming
"climate change"
without having
supporting data,
is junk science.
