Record
warm oceans have spawned scary slate of monster tropical cyclones
By

In
the past six months, the Earth has witnessed several of the
freakiest, most intense storms in recorded history.
Spurred
by the highest ocean temperatures observed to date,
record-breaking tropical cyclones — the class of storms that
includes hurricanes and typhoons — have explosively developed in
three regions: the
northeast Pacific Ocean, the south Pacific Ocean and the Indian
Ocean.
These
storms may be a harbinger of increasingly severe tropical
cyclones in future decades as the Earth continues warming.
The
most recent vicious storm, Tropical Cyclone Fantala, attained peak
winds of 173 mph north of Madagascar this past weekend. According
to meteorologist Bob Henson at Weather Underground,
it became the most intense tropical cyclone on record in
the Indian Ocean. Fantala has since lost some steam andis
forecast to
weaken to a tropical storm over the southern Indian Ocean by early
next week. Fortunately, it has avoided any land areas.
Just
two months before Fantala, Tropical Cyclone Winston became
the fiercest storm on record in the South Pacific, with peak winds of
185 mph. This storm devastated parts of Fiji.
And
four months before Winston, Hurricane Patricia (October 2015)
became the strongest storm measured to date by the National Hurricane
Center in the Northeast Pacific. Its peak winds reached 215 mph
before it slammed into Mexico’s west coast.

catastrophic’ Patricia, the strongest hurricane ever recorded,

Patricia
was just one of 25 Category 4 or 5 tropical cyclones in 2015 in the
Northern Hemisphere, the most on record by far.
This
is not to mention November 2013’s Super Typhoon Haiyan, which
became the strongest tropical cyclone in the northwest Pacific
(and the Eastern Hemisphere) based on wind speed. Its
195 mph maximum sustained winds devastated parts of the
Philippines.

To
be sure, because the intensity of these storms was not observed by
aircraft, except for Patricia, there is some uncertainty in their
exact measurements. And, the period of record in the Indian
Ocean, where Fantala developed, only dates to 1990.
But
all of these storms formed in areas where ocean
temperatures were much warmer than normal and during an era
in which ocean temperatures are warming.
The
recent ocean heating provided by El Niño, particularly in the
Pacific, has certainly played a role in this flare-up of intense
storms. But the longer-term ocean warming trend, related to
growing concentrations of greenhouse gases in the atmosphere, is very
likely to be playing an important role as well.
Published
studies have
documented an increase in the intensity of the strongest storms in
several ocean basins in
recent decades, although an
unambiguous global warming signal in tropical cyclone activity hasn’t
emerged. Such
a signal is expected to become clearer in the future.
A
NOAA-led study published in September projects
increases in “the number and occurrence days of very intense
category 4 and 5 storms” by the end of the century, and, more
generally, NOAA
projects an
increase in the average intensity of tropical cyclones.
Fantala,
Winston, Patricia and Haiyan may portend more frequent and
intense severe tropical cyclones, especially during El Niño
episodes in the Pacific (in the Atlantic, more intense storms would
occur during La Niñas).
Climate-change
warnings include rising seas and wild weather shifts. But giant
flying boulders?
Standing
atop a 60-foot cliff overlooking the Atlantic, James Hansen — the
retired NASA scientist sometimes dubbed the “father of global
warming” — examines two small rocks through a magnifying glass.
Towering above him is the source of one of the shards: a huge boulder
from a pair locals call “the Cow and the Bull,” the largest of
which is estimated to weigh more than 1,000 tons.
The
two giants have long been tourist attractions along this rocky coast.
Perched not far from the edge of a steep cliff that plunges down into
blue water, they raise an obvious question: How did they get up here?
A
matter of degrees: Diplomats are heading to Paris to come up with a
plan for averting the worst effects of climate change. Their goal:
Keep global temperatures from rising more than two degrees Celsius
over preindustrial levels. But are they too late?
Compounding
the mystery, these two are among a series of giant boulders arranged
in an almost perfect line across a narrow part of this 110-mile-long,
wishbone-shaped island.
Hansen
and Paul Hearty — a wiry, hammer-slinging geologist from the
University of North Carolina at Wilmington who has joined him here as
a guide — have a theory about these rocks. It’s so provocative —
and, frankly, terrifying — that some critics wonder whether the man
who helped spawn the whole debate about the dangers of climate change
has finally gone too far.
The
idea is that Earth’s climate went through a warming period just
over 100,000 years ago that was similar in many ways to the warming
now attributed to the actions of man. And the changes during that
period were so catastrophic, they spawned massively powerful
superstorms, causing violent ocean waves that simply lifted the
boulders from below and deposited them atop this cliff.
If
this is true, the effort kicking off in Paris this week to hold the
world’s nations to strict climate targets may be even more urgent
than most people realize.
Hearty,
an expert on Bahamas geology, first published in 1997 the idea that
Cow and Bull were hurled to their perch by the sea. Since then,
Hansen has given the work much added attention by framing the
boulders as Exhibit A for his dire view of climate change — which
has drawn doubters in the scientific community. But as Hansen
examines the rocks on a recent morning, Hearty explains some of the
evidence. In particular, Hearty points out that the tiny grains that
constitute the boulder rocks are more strongly cemented together and
less likely to crumble than other rocks nearby, a sign that the
boulders are older than what’s beneath them.
“Yeah,”
Hansen says with a nod, rubbing the younger rock and watching it
crumble a little. He sees the difference. It’s a key point the two
use to argue that the placement of these boulders indicates a
dramatic hurling of the rocks by the sea. Even on a calm day, the
deep blue waters of the Atlantic slam against the cliffs below with
audible force and huge plumes of spray. But could waves have lifted
these massive stones?
While
there is a suggestion in the scientific literature that the boulders
were simply left behind after surrounding rocks eroded away, Hearty
and another leading Bahamas geology expert, Pascal Kindler of the
University of Geneva in Switzerland, agree that the boulders are
older than the surface upon which they rest and, thus, probably were
moved by the sea. Even the tourist placard near here takes their
side, saying the ocean “lifted them atop the ridge.” But exactly
how it could have done that is another matter.
Scientists
have tended to attribute odd boulders such as these to tsunamis —
there’s little doubt they have the power to move large rocks. One
recent study found that in the Cape Verde islands, 73,000 years ago,
a 300-foot-high mega-tsunami carried boulders as large as 700 tons
atop a cliff almost as high as the Eiffel Tower.
But
more recent studies have also attributed large boulder movements to
storms. And now into the fray has stepped Hansen, who, in 1988
testimony before Congress, put the climate issue on the map by
contending — correctly, as it turned out — that global warming
had already begun. If he is also right about the boulders, Earth
could be in for a rough ride.
And
even if not, one thing is clear: Cow and Bull present a scientific
mystery whose solution may serve as a reminder of just how violent
and dynamic a planet we live on...[ ]
