WARMING PACIFIC OCEAN, SEA
LEVEL RISE, HAIYAN’S FURY AND SURGE – EXPECT MORE AND INCREASINGLY MORE INTENSE
TYPHOONS IN THE NEAR FUTURE BECAUSE OF CLIMATE CHANGE
DIGITAL ARTIFACT submitted by ROILO GOLEZ on 19 February 2014 as part of the requirements to complete his participation in World Bank’s Massive Open Online Course (MOOC), based on the report Turn Down the Heat: Why a 4°C Warmer World Must be Avoided.
The World Bank’s Massive Open Online Course (MOOC) Climate Change Course has provided me adequate technical information on the new
physics and dynamics of tropical cyclones, like HAIYAN or YOLANDA (the
Philippine name of the typhoon) which struck our Visayas region on November 8,
2014 killing more than 6,000 and destroying billions of pesos worth of infrastructure
and properties along its deadly swath.
But
beyond the shocking and mindboggling story of the devastation is the clear
message of the “Turn Down the Heat” report:
THERE IS SCIENTIFIC BASIS TO
EXPECT THAT MORE, EVEN STRONGER TYPHOONS WILL COME, NOT AFTER MANY YEARS BUT MUCH
SOONER, AS THE WORLD CONTINUES TO WARM AND AS NATURE SIMPLY FOLLOWS THE
INVIOLABLE LAWS OF PHYSICS THAT CREATED HAIYAN.
An
urgent, compelling public information campaign must be implemented immediately
to save lives and properties and the government must review and redirect the government's multibillion dollar rehabilitation program.
The day before the typhoon hit the Philippines, dire warnings came out in the news
The
danger was clearly explained by tropical
weather expert Brian McNoldy at the Capital Weather
Gang, the Washington Post's weather blog.
Live Science summarized McNoldy’s technical explanation of why they project a
super typhoon. Please note the article from Live Science:
How Typhoon Haiyan Became Year's Most Intense
Storm
By Douglas Main, Staff Writer

This
article explained in scientific terms how the typhoon built up to become a super typhoon packing
300 kph winds:
“Haiyan got so strong because ‘it has everything working
for it,’ McNoldy said. First, it formed in the open ocean, and thus no land
mass prevented it from forming a symmetrical circular pattern, which helps a
cyclone form and gather steam, he said.
“Second, ocean temperatures are incredibly warm, topping
out at 86 degrees Fahrenheit (30 degrees Celsius). Just as important, the
warm water also extends deep into the ocean, meaning that upwelling caused by
the winds will not churn up cold water, which dampens cyclone power, McNoldy
said. Tropical cyclones are basically giant heat engines, powered by the
transfer of heat from the ocean to the upper atmosphere.
“Third, there is very little wind shear in the area at
this time, McNoldy said. Wind shear, a difference in wind speed or direction
with increasing altitude, tears developing hurricanes apart, and prevents them
from strengthening. Wind shear caused by westerly winds is the main reason why
the Atlantic hurricane season featured few strong
storms, and got off to a late start, weather experts say.”
THE article had a very clear warning
on the SURGE that should have been frightening enough had it been treated like a Tsunami
warning, but it was overshadowed by the headlines on the forecast of record
300-kph winds:
“Haiyan is likely to
push a large storm surge inland — at least 10 feet (3 meters) — along the
eastern coast of the islands of Luzon and Samar, according to the Washington
Post's Capital Weather Gang blog.”
The people and local authorities
prepared for the strong winds, the way they had done for decades, even centuries. The government issued a warning about the SURGE,
but it got submerged under the warning on the extreme strong winds. The SURGE
was the more destructive killer, sweeping and destroying homes and killing
people who could have evacuated to higher grounds had a clear Tsunami like
warning on the SURGE been issued. People braced for the winds, but not the
SURGE.
The SURGE was never fully explained
in the government warnings. People in the coastal areas of Samar and Leyte were
caught flatfooted, including local officials, the police and the military, whose
homes and offices were wiped out. With clearer warnings on what the SURGE
meant, they could have evacuated to higher ground and thousands of lives could
have been saved.
Below is a photo of the Severe
Weather Bulletin Four-A of the Philippine Weather Bureau better by its acronym
PAGASA issued at 8PM November 7, 2013 on the eve of the typhoon’s landfall.

"At the bottom of the forecast – in a footnote-like text – is a
warning against possible 7-meter high storm surges in areas declared under
signals 4, 3, and 2."
Note the very minimal, "by the way" style, virtual footnote mention of
the SURGE around 57 lines from the top of the bulletin, when it should have
been included among the top weather forecast items to emphasize the danger.
Following the thrust and tenor of the
government’s weather bulletin, Philippine
Star, one of the country’s biggest newspapers, also minimally mentioned the
surge among the last items in its headline news on the “Monster typhoon” the
day before the storm.

"MANILA,
Philippines - Public storm warning signal number 4 has been
raised over more areas in Visayas on Thursday evening after Super Typhoon
"Yolanda" slightly accelerated and intensified, state weather bureau
PAGASA said.
"In a severe weather bulletin
issued at 8 p.m., PAGASA said Yolanda was last spotted at 453 kilometers
southeast of Guiuan, Eastern Samar with maximum sustained winds of 225
kilometers per hour near the center and gusts of up to 260 kph.
And then around 67 lines after the first line
of this news is a “by the way, hard to notice mention of the surge:
“Those living in coastal areas under
signal nos. 4, 3 and 2 are alerted against storm surges which may reach up to a
seven-meter wave height."
The lack of advance alarm and
awareness on the SURGE was evident from local Philippine TV news quoting the
Mayor of the devastated City of Tacloban:

:
“Tacloban City Mayor Alfred Romualdez on Monday
admitted that his government found it difficult to explain what a storm surge was
to his constituents before Typhoon Yolanda (Haiyan) ravaged through their area
last month. "There was a difficulty in explaining to the public what a
storm surge is. We were aware of the height, but not the strength,"
Romualdez said.
And the PAGASA, the Philippine Weather Bureau,
admitted this lapse as indicated by this Rappler
news story six days after the typhoon struck.

'Storm surge' not explained enough – PAGASA
official
BY BUENA BERNAL
POSTED ON 11/14/2013 7:22 PM
MANILA, Philippines – As far as the
Philippine Atmospheric Geophysical and Astronomical Services
Administration (PAGASA) is concerned, all necessary public warnings were issued
before Super Typhoon Yolanda (Haiyan) unleashed its wrath Friday, November
8.
Ma. Cecilia Monteverde, assistant weather
services chief of PAGASA, however, admitted that more could have been done
in explaining to the public the magnitude and gravity of
a storm surge.
"We weren't able to tackle that. It's more
on the signals and in delivering the forecasts and
warning distributed to the public. But the storm surge wasn’t
explained there," Monteverde, speaking in Filipino, told
Rappler.

destruction:
There is an urgent need to educate
the public and public officials who are supposed to protect the public from
extreme weather events.
The dynamics of typhoons have changed: This World Bank Turn Down the Heat Climate Change Course offers more
technical explanations that should be stressed to the public so they will
better understand that the dynamics of typhoons have changed
radically, that typhoons and its consequences have become more severe because
of Climate Change.
The course, through a comprehensive
formal report and very educational videos, provides technical explanations,
which I believe most laymen, including high school students, can easily
understand.
Very important is the lecture on Sea
Level Rise which we can call “Sea Level Rise 101”: "Impact
of sea level" by Prof. Stefan Rahmstorf, Professor of a Physics of the Ocean, Potsdam University, Germany. https://class.coursera.org/warmerworld-001/lecture/39
I selected the following excerpt from that
video and created this YouTube video under my account for easier reference:
Prof. Rahmstorf clearly and scientifically
explained how the location of the Philippines aggravated the impact of Haiyan:
“Part of the devastation was due to a big storm surge. Made much worse by the
fact that sea level in that area in the Philippines rose much higher than
anywhere else in the planet. Observed sea level rise since 1993 by satellite.
There's an exceptionally large rise in the tropical Western Pacific. Where does
this come from? This is because of the fact that the trade winds that blow from
East to West near the equator have increased in the last decades pushing more
water towards the West piling it upon the side of the Philippines.”
Prof, Rahmstorf provided these photos in his
video presentation where the Philippines is situated in the red area, the
region of highest sea level rise. I took digital photos of two of Prof. Rahmstorf's slides and present them here:
The major stories and articles on
Haiyan or Yolanda blamed Climate Change or global warming as the cause of extreme
weather events. But there is no prominent mention of sea level rise as a major
aggravating factor that made the surge deadlier.
Note this article
in the Telegraph headlined “The truth behind Haiyan.” This was a full week after
the typhoon struck.
http://www.telegraph.co.uk/earth/environment/climatechange/
“There is, though, one far less
discussed factor that appears to have aggravated Haiyan’s impact: rising sea
levels do seem to have swelled the storm surge that caused most of the
deaths."
Another danger: There is the dangerous public impression that Haiyan could
be an isolated super typhoon that could take years to repeat. This is dangerous and should be
corrected.
The public and
pertinent public officials must be informed and educated that there is technical and
scientific evidence that another Haiyan or even stronger typhoon is very likely and can become regularly recurring extreme events in the future because the physical causes remain and could even get worse as
the earth gets warmer towards an increase by 2°C or worse.
And the trade winds pushing the Pacific seas from East to West will certainly continue to make the sea level around the Philippines the highest in the
world, thus posing the danger of a deadlier SURGE the next time a highly probable
typhoon from the wide open Pacific Ocean comes again.
The Climate Change Course explains clearly that the Philippine
is at the center of the highest risk by events triggered by global warming:
1. The report “Turn Down the Heat” prepared for the World Bank by
the Potsdam Institute for Climate Impact Research and Climate Analytics cites
the scientific explanation on sea level rise: “thermal expansion of the oceans
and by the addition of water in the oceans as a result of the melting and
discharge of ice from mountain glaciers and ice caps and from the much larger
Greenland and Antarctic ice sheets,” all of these as a direct result of global
warming due to increases in greenhouse gases. The public must know this, as
most of the articles on sea level rise are generally limited to mentioning
global warming. More than any other country in the planet, the Philippines appears to be the most vulnerable to sea level rise. The public and public officials must be better educated on the chain of events
leading to sea level rise and why it could get worse as a matter of the
inviolable laws of physics at work from greenhouse gases to global warming to
sea level rise to impress upon the public that continued carbon emissions
and other greenhouse gases would inevitably lead to more sea level rise. And for
the Philippines, there is a need for greater awareness of the scientific
finding that the rise in our part of the world, in the low latitude region in
the tropics, is 15-20% higher. The videos on sea level rise by Prof. Prof.
Rahmstorf are very effective in explaining this. I believe this video must be
propagated and reechoed in the countries like the Philippines facing grave sea
level rise threats.
2. That the East-West trade winds push the seas towards the Philippines is a revelation. Of course
the trade winds are not directly triggered by global warming, but the important
point is that it is that it seriously exacerbates the combination of SLR
highest in the tropics and the Philippines in the typhoon belt.
There is therefore a need to explain to the public what the SURGE is and how
the sea level rise is the Philippines area is highest in the whole planet because of
the convergence of two factors: (1) The Philippines is located in the low
latitude region near the Equator where Sea Level Rise is 15-20 % higher than
the global median sea level rise, and; (2) the East-West trade winds that push
seas towards the area of the Philippines generating more sea level rise.
In the public information campaign, the SURGE must be given the alarming image of a TSUNAMI, simple mention of which will send the
people scampering to higher grounds.
The public information campaign must stress that the increase from a
warming of .8°C to 2°C by the middle of this century is not a
small difference, that it is big and can magnify consequences into catastrophic
proportions.
It must be stressed that the Pacific
Ocean will not change, it will remain a vast ocean that will continue to give a
storm the wide open space to build up momentum and that the seas will even get
warmer to feed more power to the storm since “Tropical cyclones are basically giant heat engines, powered by the
transfer of heat from the ocean to the upper atmosphere.”
The public must be also be made very aware that the Sea Level Rise, in addition to aggravating the SURGE, also triggers the following dire consequences:
1. Destruction of coral reefs thus jeopardizing the millions who depend on
the coral reefs for income and food. Dr. Janice Lough in
Video 12 "What happens to coral reefs" https://class.coursera.org/warmerworld-001/lecture/43 warned that “Additional source of physical destruction to coral reefs
is by the big storms. It takes about ten to twenty years to recover. Storms are
likely to be more intense.”
2. “Rising
sea levels mean greater threats to Coastal aquifers and ground water systems.
Salt water pushing fresh water, affecting the health of ecosystems. Sea level
rise is accelerating around the world. As much as 10% of agricultural land may
be vulnerable” this was eloquently explained by Dr. Peter Gleick in Video 8 of
the Course entitled “Risks to Global Water Reources”, https://class.coursera.org/warmerworld-001/lecture/37.
3. Rising
sea levels cause “saltwater intrusion into freshwater aquifers, freshwater used
for drinking get infiltrated by saltwater, water could become unusable. Worst
impact is the greatly increased danger of coastal flooding. Vulnerable coasts
are the whole of Africa, Madagascar, South Asia, small islands in Indian Ocean,
Indonesia, Indochina, Thailand, China, Taiwan and the Philippines…” explained
clearly by Prof. Stefan Rahmstorf in Video 10 of the Course.
This is the
Philippine Climate Change Action Plan approved by the Philippine President in
November 2011 (http://www.dilg.gov.ph/PDF_File/resources/DILG-Resources-2012116-d7b64f9faf.pdf)
There is no prominent
mention of how to cope with Haiyan class or, expectedly, much worse typhoons. Now, typhoons must be given very dominant attention,
commensurate to the potential damage it can inflict on the country, as
demonstrated by Haiyan and as explained by science.
Per
media report (Rappler), the Philippine government has announced a P361Billion or US$8 B Program for post-HAIYAN or
Yolanda rehabilitation http://www.rappler.com/nation/46153-philippines-recovery-assistance-yolanda-haiyan-funds.
The rehab breakdown is as follows:
Bulk of this amount will go to rebuilding homes until
2017. The Philippine government said it will use 50.79% of this
amount, or P183.3 billion, for shelter and resettlement.
The next biggest chunk, or around 19.56% of the total, will go
to jobs and businesses. The industry and services sector,
which includes livelihoods, enterprises, and services, will require P70.6
billion.
The other investment requirements include the following,
from highest to lowest:
Education
and health services – P37.4 billion
Public
infrastructure – P28.4 billion
Agriculture,
including crops, livestock, and fisheries – P18.7 billion
Social
protection – P18.4 billion
If most of the rehab
projects are going to be along the path of future, much stronger typhoons, plus
the SURGES, is it wise to make those investments that would also, based in
scientific evidence, be vulnerable to future, even stronger typhoons? What is the probability of another Haiyan-class typhoon hitting the area within one to two years while the rehab is ongoing with billions already expended? Is it better to relocate farther inland?
The Climate Change Course includes a video lecture entitled "Act Now, Act Together, Act Differently in Response to Climate Change" by Marianne Fay, Chief Economist, Sustainable Development and Climate Change Group, World Bank, https://class.coursera.org/warmerworld-001/lecture/47
She gives this advice which is most relevant to the Philippine Haiyan experience:
For "better climate information systems," the national and local governments must work and "act together" for an intensive public information campaign on the new dynamics and physics of typhoons and SURGES, among others. Below is Madam Fay's model for an information system:
The Climate Change Course includes a video lecture entitled "Act Now, Act Together, Act Differently in Response to Climate Change" by Marianne Fay, Chief Economist, Sustainable Development and Climate Change Group, World Bank, https://class.coursera.org/warmerworld-001/lecture/47
She gives this advice which is most relevant to the Philippine Haiyan experience:
"We need to plan realistically for a warmer future.... We need to ensure that climate risks are integrated into development planning from here on out. Acting differently means new infrastructure must be built with some new extremes. In some cases, existing infrastructure may need to be relocated. This may mean coastal roads moved farther inland... We must enhance adaptation to a variety of climate future. We should develop better climate information systems to address climate risks..."
I made a You tube video of the above segment for easier reference: http://www.youtube.com/watch?v=HRp8u89TzM4
Following World Bank Chief Economist Fay's advice, the multibillion dollar rehab program must include moving farther inland the coastal road system and other infrastructures of Leyte and Samar to avoid destruction by super typhoons which appear inevitable in the near future.
For "better climate information systems," the national and local governments must work and "act together" for an intensive public information campaign on the new dynamics and physics of typhoons and SURGES, among others. Below is Madam Fay's model for an information system:
Beyond the debate on mitigation and adaptation to cope with
Climate Change is the need to strongly convey to the Philippine public and
public officials the message, in layman’s terms, that failure to control the
warming to lower than 2°C means nature’s more intense wrath and fury
and that unfortunately, because of our geographical location, the Philippines
is one of the countries that have absorbed and will continue to absorb the full shock of Sea Level Rise, more intense typhoons and SURGES. Unfortunately, the Philippines can
control only a minute fraction of the scientific reasons for the warming of the
troposphere and the oceans, the causes of the sea level rise and typhoon
build-up, or the trade winds that aggravate sea level rise in the tropics where
the Philippines is located. The Philippines can only lobby, appeal, argue in
the various Climate Change forums of the world, this time armed with graphic
evidences of Climate Change at its most vicious in recorded history so far.
The world must respond even if they are far from the typhoon
belt because somehow Climate Change’s many horsemen of the apocalypse, not just
four but more, will visit them in another form, such as droughts, diseases,
floods, famine, crop failure, coral reef destruction, forest fires, energy breakdown,
even wars.
