No Glaciers in Glacier National Park?
Glaciers are melting, islands are drowning, wildlife is vanishing. Because
of
global warming, our most cherished vacation spots may soon cease to exist.
And travelers are part of the problem.

Sit back, close your eyes and imagine your favorite vacation
spot. That
secluded cabin on the Chesapeake. That five-star beach resort in Martinique.
The powdery slopes of Aspen in winter. The narrow streets of Paris in
summer.
Now imagine your Chesapeake cabin flooded up to the bunk
pillows by rising
bay water. The Martinique hotel boarded up and forever closed due to record
hurricanes. Those Aspen slopes snow-free and downright balmy. And Paris
so
hot and smoggy that you venture out for baguettes only between Jerry Lewis
reruns in your air-conditioned Left Bank hotel room.
Why entertain such dreadful thoughts? Because a growing
body of scientific
evidence points to a trend that could spell heartbreak for future tourists
and catastrophe for many sectors of the tourism industry. Global warming,
driven mostly by carbon dioxide and other heat-trapping gases spewed skyward
by the world's bustling fossil-fuel economy, could negatively affect many
of
the world's most-visited tourist destinations within the next few decades.
And tourists themselves, ironically, are contributing
mightily to the
problem, traveling in ever-higher numbers on a planet where virtually
every
new snowmobile, jumbo jet, cruise liner, Winnebago, hot tub and
air-conditioned hotel ballroom draws power ultimately from oil, gas or
coal.
These fuels, once burned, add directly to the CO2 load threatening the
very
destinations people love to visit.
If you have trouble picturing your own favorite getaway
spot despoiled by
global warming and its seemingly science-fictionlike consequences, consider
the physical evidence already on display:
• Spawned by just one degree of planetary warming in the
20th century,
glaciers worldwide are retreating at breathtaking speed. Spots like Africa's
fabled Mount Kilimanjaro will be ice-free in just 15 years and Montana's
Glacier National Park will be devoid of glaciers in 70 years if current
trends hold, according to recent studies.
• Coral reefs, which attract multitudes of flipper-footed
tourists to
tropical playgrounds worldwide, are likewise in free-fall decline.
Twenty-seven percent of the world's reefs have been destroyed in the past
50
years due to rising sea surface temperatures and other factors, and another
32 percent are at risk of dying by 2050, again with water temperature
a
factor, according to the Global Coral Reef Monitoring Network, an
international clearinghouse for coral reef studies in Townsville, Australia.
• Far-flung travel guides and outfitters report strange
and suddenly
unpredictable rainfall patterns worldwide that frustrate tourist activities,
and warmer temperatures that could widen the range of malaria-bearing
mosquitoes, affecting potentially millions of travelers.
• Perhaps the most surreal indication of what might be
in store comes from
the idyllic, tourist-friendly island nations of Tuvalu and Kiribati, in
the
South Pacific. Tuvalu is developing concrete emigration plans to evacuate
its
islands – perhaps entirely – in this century, migrating en masse to "host
countries" like New Zealand. This is because scientists say sea-level
rise
could inundate Tuvalu and other low-lying island countries almost entirely
as
polar ice melts and ocean water expands. Rising ocean water in Kiribati
is
already destroying coastal roads and crops.
Beyond the obvious hardships on local populations, these
and other
climate-related changes could have a huge impact on many sectors of the
travel and tourism business. That industry is now the world's largest,
accounting for 11 percent of the world's gross economic product in 1999,
with
$3.5 billion in direct and indirect receipts, according to the World Travel
&
Tourism Council (WTTC), an industry trade association based in London.
"Tourism is an industry harmed by any harm to the
environment. Period," says
Bill Maloney, executive vice president of the American Society of Travel
Agents in Alexandria. "Global warming is definitely on our radar
screen of
concerns."
Jerry Mallett, president of the Adventure Travel Society,
an international
trade association in Salida, Colo., dials up the concern level much higher.
"Given the growing scientific data, my fear is we're
all going to wake up
soon and find the places we love totally gone – even in our lifetime,"
says
Mallett. "Global warming is a train wreck about to hit the world
tourism
business, and I think we've all been asleep at the switch."
Alarming Predictions
Underlying much of the recent concern are the unsettling
findings of the most
authoritative global-warming report to date, published this summer by
the
U.N.-sponsored Intergovernmental Panel on Climate Change (IPCC). The
3,000-page "Third Assessment Report," drawing exclusively on
published,
peer-reviewed studies conducted by thousands of the world's leading
climatologists, oceanographers, geographers and other scientists, projects
a
warming of between 2.5 and 10.4 degrees Fahrenheit in global mean surface
temperatures by 2100, unless greenhouse gas emissions are cut well below
current levels. This warming would be the fastest in more than 10
millenniums, with potentially profound disruptions to human life worldwide.
In June, at the request of President Bush, a panel of
top American scientists
– including previous skeptics about global warming – reviewed the IPCC
report
under the auspices of the National Academy of Sciences and confirmed its
fundamental findings that global warming is a real phenomenon – and is
getting worse.
Ralph J. Cicerone, the chancellor of the University of
California at Irvine
who led the NAS panel, said in an interview that the IPCC report is
"admirable science." While acknowledging that uncertainty exists
over the
exact nature of some impacts from warming, Cicerone said he hoped the
NAS
review would dispel unwarranted, lingering doubts about the reality of
human-induced global warming.
As for tourism, the IPCC report projects warming scenarios
with negative
implications for everything from bird-watching to urban walking tours.
A few regions might actually benefit. Canada, for example,
could have a
longer season for golf and other outdoor recreation, according to the
IPCC.
But on the whole, the forecast is not good, with potentially major injuries
to ecosystems and wildlife worldwide (and the ecotourism companies they
sustain); less snow and ice for winter recreation; and adverse impacts
on
fishing, white-water rafting and many other recreational pursuits, as
interior continental regions get hotter and drier.
The most alarming impact could come from sea-level rise,
which the IPCC
projects could reach as high as three feet by 2100. A rise of only half
that
much would wreak havoc on seaside resorts and ports of call worldwide
as
seawater erodes beaches, inundates coastal property and intrudes into
drinking water. America's coastlines alone, according to the IPCC, attract
as
many as 180 million recreational visitors each year.
"And all U.S. coastlines are vulnerable, absolutely,"
says Virginia Burkett,
an American wetlands scientist and lead author of the IPCC report section
on
coastal areas. "Given even middle-range sea-level rise associated
with
climate change, shorelines will tend to peel back and transgress inland.
Whatever beach tourists tend to visit, they'll likely see some significant
level of degradation."
Unprecedented Changes
The impact of rising temperatures is already being observed
by scientists
and, anecdotally at least, by some tour operators.
The IPCC report cites a diverse array of evidence suggesting
the planet is
undergoing an unprecedented transition away from the relatively stable
climate of the past 10,000 years. "Recent regional climate changes,
particularly temperature increases, have already affected many physical
and
biological systems," according to the report. In addition to glacier
retreat
and declining coral reefs, these effects include "thawing of permafrost,
later freezing and earlier break-up of ice on rivers and lakes . . . poleward
and altitudinal shifts of plant and animal ranges, declines of some plant
and
animal populations, and earlier flowering of trees, emergence of insects,
and
egg-laying in birds."
Many tourism outfitters report equally strange weather
phenomena and
consequences. Will Weber, founder and director of Journeys International
in
Ann Arbor, Mich., believes his adventure travel company is being affected
by
global warming. Weber has spent the past 23 years organizing thousands
of
trips on every continent, from rafting the Zambezi River to ice camping
on
the Antarctic Peninsula to horseback riding across Patagonia. But in the
past
10 years, he says, he's become increasingly unable to answer two questions
most commonly asked by his clients: What's the weather going to be like
where
I'm going, and how do I prepare for it?
"The weather's just turned really wacky almost everywhere
we do business,"
says Weber. "Fifteen years ago, if you were going to the Serengeti
in April,
you'd be guaranteed to see rain. Now? Who knows? Around the planet, we
see
dryness in wet seasons and rain in dry seasons, weird temperatures and
weird
storms. We're just not sure what to tell people anymore."
While it's possible Weber is simply observing natural
weather variations in
the regions where he operates, the retreat of glaciers worldwide is beyond
dispute. That retreat is creating headaches for companies like Weber's.
Base
camp facilities constructed at the foot of a glacier are a mile from the
ice
10 years later. Just now, Weber has a group of Boy Scouts scheduled to
climb
Credner Glacier on Africa's Mount Kilimanjaro, but he's afraid the glacier
will be diminished beyond recreational use by the time the scouts arrive
later this year.
Travelers devoted to ecotourism – perhaps the industry's
fastest-growing
sector with a 20 percent annual growth rate and $154 billion in receipts
in
2000, according to the International Ecotourism Society in Burlington,
Vt. –
could face the greatest disappointment of all. Rising temperatures will
almost certainly inflict significant harm on fragile ecosystems worldwide,
according to the IPCC, increasing existing risks of species extinction
and
loss of biodiversity. Ecosystem collapse would be likely in many regions.
Areas of particular vulnerability include:
• Polar ecosystems, where Antarctic penguins have already
declined by half
over the past 50 years due to warming sea-surface temperatures, and where
Hudson Bay polar bears are having smaller litters, apparently due to ice
depletion.
• Africa, where any significant disruption of historic
rainfall patterns
could seriously affect big-game safaris, throwing into chaos the fragile
fabric of plant and animal life linked to the age-old migration of species
like the wildebeest in the Serengeti. These complex ecosystems, once lost,
might never be restored.
• Seaside resorts and beaches worldwide, where rising
sea levels could result
in beach erosion, flooding and drinking-water contamination.
• Large European and North American cities, which may
become undesirable in
summer because of heat and worsened urban air quality. Low-lying coastal
cities like Venice, New Orleans and Miami would have the added challenge
of
sea-level rise.
• The tropics, where the IPCC projects storms will likely
grow more powerful
in a rapidly warming world. Storms could usher in the ultimate poison
pill
for tourism-dependent businesses: the inability to get insurance. Geoffrey
Wall, a tourism expert and geographer at Ontario's University of Waterloo
who
helped author the IPCC section on tourism. and others say if storms become
more fierce, insurance rates will almost certainly rise in many coastal
areas, with uninsurability a potentially widespread scenario. Insurance
rates
are already climbing in the Caribbean region, according to Wall, due largely
to increased storm damage.
To illustrate the danger, analysts point to Hurricane
Andrew in 1992, the
costliest natural disaster in American history. Andrew bankrupted nine
insurance companies, throwing the Florida insurance industry into crisis
at
the same time IPCC scientists began forecasting more intense storms as
the
globe warms.
Paying the Price
To date, no one has attempted to quantify the total potential
financial loss
to tourism spawned by unchecked global warming. How do you put a price
tag on
Australia's Great Barrier Reef? Or the dreamlike climate of the Turkish
Mediterranean coast in spring? By any reckoning, the threat is potentially
enormous and, with the IPCC report, beginning to resonate with industry
leaders. Already, the first-ever international conference on climate change
and tourism has been scheduled for October in Greece, involving
climatologists, industry analysts, government policymakers and business
owners. A second conference is scheduled for 2003.
"Clearly, global warming is an issue the tourism
industry must – and I think
will – pay more and more attention to in the near future," says Wall.
But given the IPCC's finding that planetary warming is
already happening, and
given the prospect of at least moderate warming and sea-level rise in
the
near future even under the most optimistic mitigation scenarios, Wall
says
that at-risk tourism sectors have no choice but to prepare for and adapt
to
climate-related impacts already in the pipeline.
Ski resorts, for example, may need to counteract warmer
temperatures by
pushing slopes farther up mountainsides, if possible. They might also
want to
"diversify" their services by offering ski-lift access to summer
hikers. And
investors eyeing construction of new beach resorts should build facilities
significantly farther back from the surf in anticipation of sea-level
rise,
according to Wall – a process the IPCC report calls "managed retreat."
Beyond adaptation, many industry observers say any strategy
aimed at slowing
global warming and restabilizing the world's climate must include a close
look at the travel and tourism industry's own contribution to greenhouse
gases.
Air travel and transport alone, for example, add more
than 500 million tons
of CO2 to the Earth's atmosphere each year, according to the IPCC. And
as
people travel more, courtesy of ever-rising Western affluence, the problem
only gets worse. By 2050, a full 15 percent of the world's CO2 could come
from travel and tourism, according to Green Globe 21, a Bournemouth, England,
trade association.
"We're loving the planet to death," says John
Berger, author of "Beating the
Heat: Why and How We Must Combat Global Warming." "You look
at the IPCC
findings and you realize tourists and travel businesses – just like all
people and all businesses in the developed nations – have to reduce their
contribution to the problem or perhaps say goodbye to places and things
they've always considered eternal."
How that can be done is a hot-button political issue in
the United States,
given the current era of SUV mania and a conservative White House firmly
opposed – due to economic fears – to the internationally negotiated Kyoto
protocol, which is aimed at cutting global emissions of greenhouse gases.
But
the IPCC report makes clear that the goal of stopping global warming can
only
be achieved by cutting such gases, especially CO2, well below current
levels.
Hence, travelers should consider reducing their use of
fossil fuels – at home
and away – while supporting the development and use of nonpolluting renewable
energies (solar, wind, fuel made from plants), according to Wall and others.
Already, a few pioneering companies have begun marketing "low-impact"
recreation to tourists, and others are setting company CO2-reduction goals
with environmentally conscious travelers in mind.
Travelers' Choices
Though the research is discouraging and often frightening,
many scientists
agree that meaningful reductions in CO2 emissions could restabilize the
world's climate in time to prevent most of the worst effects. As for
tourists, not only can they contribute individually to the solution, but
the
tourism industry as a whole, some observers believe, could serve as an
important tool for mass education and a model for global change.
The Aspen Skiing Co. (ASC) certainly thinks so. Two years
ago, in direct
response to global warming and other environmental concerns, the nation's
fifth-largest ski-resort company designed and constructed its own "green"
restaurant and ski lodge. The 24,000-square-foot facility features recycled
building materials, passive solar heating and 30 percent wind-generated
electricity, representing an industry model of eco-friendliness. One entire
ski lift is also powered by renewable energy. And last April the same
company
adopted the ski industry's first-ever corporate policy on climate change,
pledging a 10 percent reduction in total company CO2 emissions by 2010.
Today, upon arrival, guests of the Aspen Skiing Co. are
given suggestions on
how they can lessen their own impacts during their stay (don't wash hotel
linens daily; take free shuttles from hotels to the slopes) and things
they
can do upon returning home, including using energy-saving fluorescent
bulbs
and turning water heaters down to 120 degrees.
To lessen industry impact further, the nonprofit trade
association Pacific
Asia Travel recently proposed recommendations ranging from increased emphasis
on rail travel to lowering the ceilings of hotel ballrooms (saves on heating
and cooling) to developing standard environmental "audits" to
help companies
voluntarily measure their CO2
output.
Meanwhile, the British environmental trade association
Green Globe 21 has
established a Web site for tourists interested in learning more about
global
warming and what can be done (see box). Starting later this month, tourists
can even use a "CO2 calculator" on the site to assess the impact
of their own
trips on global warming. And in 1999, in the only comprehensive, worldwide
program of its kind, Green Globe 21 began officially certifying "green"
tourism companies – with an emphasis on CO2 reduction – and providing
a
directory for interested tourists (see box).
Educating government policymakers about climate change
impacts should be an
additional strategy of the tourism industry, according to Eugenio Yunis
of
the World Tourism Organization (WTO) in Madrid. The WTO, an intergovernmental
research and support group whose members include 135 national governments
from five continents, has recently commissioned a $70,000, first-of-its-kind
study to estimate global warming's potential impact – in dollars – on
winter
recreation destinations and small-island nations worldwide.
"Our hope is that more concrete monetary figures
will help clarify the
gravity for both the industry and for world leaders," says Yunis,
who heads
the WTO office for sustainable tourism development.
"Just as tourists need to realize the possible loss
of destinations they
cherish," says Yunis, "governments need to see the loss to the
world
economy." Still, some observers see risks for the industry in fighting
global
warming. Any international protocol, for example, mandating sharp cuts
in CO2
emissions could seriously dampen air travel to distant destinations, bringing
near-term losses to many businesses. Additional fears exist over suggestions
that tourists be encouraged to voluntarily travel closer to home.
Despite all the recent and fast-blooming attention paid
to global warming and
various concrete steps toward a solution, the tourism business as a whole
is
still only just now waking up to the issue, industry experts agree.
"To be honest," says Maloney of the American
Society of Travel Agents, "we
still tend to be more focused on short-term issues like dead animals in
Europe and Seattle earthquakes than what might happen to the weather 50
years
from now."
Still, Yunis, Wall and others predict that climate change
will climb toward
the top of the industry's list of concerns as impacts rise with temperatures.
"Global warming means there are challenges ahead
for this industry," says
Yunis. "No doubt about it. The question is whether we can change
fast enough
and prepare well enough to limit the adverse effects."
Mike Tidwell's most recent book is "In the Mountains
of Heaven: Tales of
Adventure on Six Continents" (Lyons Press).
What You Can Do
Here are a few ways travelers can reduce their contribution
to global warming:
• Consider taking the train. According to the U.S. Department
of
Transportation, rail travel emits about half the planet-warming carbon
dioxide per passenger mile as car and plane travel.
• Once at your destination, take public transportation,
walk, bike or rent
fuel-efficient cars.
Avoid energy-guzzling activities such as snowmobiling,
jet skiing,
hot-tubbing and other "high impact" recreation.
• Patronize "green" companies. Some hotels,
resorts, outfitters and other
tourism-related businesses have adopted ecologically sound practices in
recent years. For a list of environmentally friendly companies certified
worldwide by Green Globe 21 – a trade association in Bournemouth, England,
that promotes green travel – visit www.greenglobe21.com and click on
"membership list," or call 011-44-1-202-312-001.
Another guide to eco-friendly tour operators, lodges and
trip-planning
consultants can be found at the International Ecotourism Society's Web
site,
www.ecotourism.org, or call 802-651-9818.
• Practice conservation measures in your hotel room: Turn
off unnecessary
lights and request that linens and towels not be washed every day.

US Senate panel delays action on Alaska drilling
------------------------------------------------------------------------------
--
USA: September 10, 2001
WASHINGTON - The Senate Energy Committee resumes debate
this week on a broad
U.S. energy bill, but will postpone until later this month any action
to open
the Arctic National Wildlife Refuge to drilling, a panel spokesman said
last
week.
Opening the Alaskan wilderness area is key to the White
House plan to boost
domestic energy supplies, but environmental groups and many Democratic
lawmakers are against it.
The panel will vote on electricity deregulation provisions this week,
but
won't consider Alaska drilling until the week of Sept. 17 at the earliest,
the panel spokesman said. The committee earlier had planned to consider
the
controversial drilling issue this week.
The Bush administration wants to open a total of 1.5 million
acres (607,500
hectares) of the refuge's 19 million acres (7.7 million hectares) to
exploration. The White House claims only about 2,000 acres (810 hectares)
of
the Alaskan wilderness refuge would be directly affected by drilling
equipment at any given time.
The refuge, located on Alaska's northern coast, is home
to snow geese,
caribou, polar bears and other wildlife. The U.S. Fish and Wildlife Service
calls the refuge "one of the finest examples of wilderness left on
the
planet" and one of the least affected by modern man.
A Democratic-sponsored energy bill does not allow drilling,
but Republicans
are expected to offer language during the committee's legislative debate
to
open the refuge.
A recent Reuters survey of the committee's 23 members
showed such legislation
would pass the panel by a one-vote majority, because of two Democrats
who are
expected to vote for drilling and one Republican who opposes it.
Democrats Mary Landrieu of Louisiana and Hawaii's Daniel
Akaka are expected
to break ranks with their party to support drilling. By contrast, Oregon
Republican Gordon Smith has said he'll vote against opening the refuge.
TEAMSTERS VS GREEN GROUPS
The committee's chairman, Democrat Jeff Bingaman of New
Mexico, said drilling
in the refuge would not produce enough oil to affect U.S. energy costs.
"Oil produced from the Arctic refuge is not likely
to influence the world
price of oil, or the prices that U.S. consumers pay for gasoline,"
he said
last week in a speech on the Senate floor.
Drilling supporters argue the refuge could hold up to
16 billion barrels of
oil. The United States consumes nearly 20 million barrels of petroleum
each
day, and must import more than half of that amount.
Green groups and some Democrats say a better energy policy
approach is to
tighten U.S. mileage standards for sport utility vehicles, pickup trucks
and
cars to reduce demand.
The Teamsters Union is lobbying senators to back the Alaska
drilling plan,
claiming it would create more than 700,000 jobs. That estimate, however,
has
been criticized by environmental groups as based on a ten-year-old study
that
didn't take into account other world oil market factors.
The League of Conservation Voters and other groups that
oppose drilling say
the number of jobs created by drilling in the refuge would be closer to
46,000.
President George W. Bush last week, expressing concern
over a report that
showed the U.S. unemployment rate hit a four-year high in August, urged
Congress to pass his energy plan.
"To help get our economy moving again, Congress needs
to enact an energy plan
which will lower energy costs and create jobs," Bush told reporters.
The administration said earlier this year that its plan
was a long-term
policy and would not have much short-term benefit.
FILIBUSTER THREATENED
The Senate energy panel has already cleared the legislation's
less
controversial research and development provisions.
Next Thursday, the committee will begin debating the bill's
electricity
market reform provisions, which could take up to three days to complete,
the
panel spokesman said.
Bingaman has said he wants the committee to finish its
work on the bill by
the end of the month. The measure would then go to the Senate floor, where
it
has an uncertain fate.
Several moderate Republican lawmakers from the Northeast
states have already
come out against drilling in the refuge, which could doom the bill.
Democrats Joseph Lieberman of Connecticut and John Kerry
of Massachusetts
have vowed to filibuste???allows drilling in the refuge.
In contrast, Republican Ted Stevens of Alaska said he
would block any bill
that does not open the refuge.
The House of Representatives approved a comprehensive
energy bill last month
that allows drilling in the refuge.
However, a shrinking budget surplus means that much of
the $33 billion in the
House bill for energy tax breaks will be rejected by the Senate, a
congressional staffer said.
"It's clear it's going to have to be scaled back
dramatically from what the
House has," the staffer said. "There aren't a lot of extra dollars
to fund
these kinds of things.

WWF leaders urge quick action to save the Arctic
------------------------------------------------------------------------------
--
CANADA: September 10, 2001
TORONTO - Quick action to save the fragile environment
of the Arctic was
urged last week by a summit of World Wildlife Fund leaders from eight
Arctic
nations.
The Arctic is seriously threatened by global warming and
oil and gas
development and nations with Arctic regions must act quickly to halt the
damage before it's too late, said WWF leaders from Canada, Russia, the
United
States, Norway, Sweden, Finland, Iceland and Denmark/Greenland meeting
in
Toronto.
Singled out for criticism were U.S. government plans to allow oil and
gas
drilling in the Arctic National Wildlife Refuge. Brooks Yeager, the WWF's
U.S. representative, said that proponents of the Arctic drilling are basing
their hopes on false pretenses.
"The amount of oil produced will not lower prices
or reduce the need for the
U.S. to find new ways to conserve," he said.
Also stressed at the meeting was the need for cooperation
in the face of
climate change in the Arctic, where, said Igor Chestin, director of the
WWF
Russian Program, the effects are most severe.
"Sweden is a small country, and we need to team up,"
said Lars Kristoferson,
chief executive of WWF-Sweden. "We have the chance to do something
before
we're up against a wall."
Monte Hummel, president of WWF-Canada, said he had lunch
with former Canadian
prime minister John Turner last week, and he quoted Turner as saying "this
is
really the last chance for humanity to get it right."
"The Arctic region pops out as having some of the
last pristine and
unfragmented areas of wildlife in the world," Hummel said. "The
WWF can't do
all of this, but it can have a key role in insuring that it gets done."

Global Warming Threatens UK With Little Ice Age
Scientists in Aberdeen have confirmed the local nightmare
of global
warming - that rising sea temperatures might be about to affect ocean
currents. Sarah Hughes, an oceanographer at the fisheries research
station at Aberdeen, told the British Association science festival
yesterday that water flow from the Arctic past the north of Scotland had
decreased by 20% since 1950. This flow is part of what marine scientists
called the "global conveyor", a vast submarine flow of water
south from
the Arctic. It is replaced by water flowing north from the tropics - the
Gulf Stream that keeps Britain 5C warmer than expected at these
latitudes. (9-07-01) From the Guardian.
