Some like it hot -- but a robin in the Arctic?
By Martin Mittlestaedt, The Globe and Mail

ENTRE17/TPEnvironment/

Saturday, Apr. 17, 2004 - In the summer of 1993, federal fisheries 
scientist John Babaluk was on Banks Island, the most westerly of the 
big islands that stretch across Canada's Far North, when some people 
showed him what had come up in the nets they had set for Arctic char. 

No one in the tiny Inuvialuit community of Sachs Harbour had ever 
seen such a fish, which wasn't such a surprise, considering that it 
was 1,500 kilometres away from home. They had caught sockeye salmon, 
normally found on the Pacific coast of British Columbia and Alaska. 

"We actually saw, recorded, took pictures and did some measurements 
on some sockeye salmon that had shown up in Sachs Harbour. That was 
the first time that any of the locals that we talked to had seen 
them," Mr. Babaluk says.

The itinerant salmon is just one of many strange sightings across the 
country. 

The Far North is being introduced to the robin, the South's harbinger 
of spring and a bird so rarely seen above the tree line that the 
Inuvialuit don't even have a name for it. 

In Southern Ontario, the Virginia opossum now thrives as far north as 
Georgian Bay. A few decades ago, it was unknown because the climate 
was too cold.

Wildlife biologists in Manitoba have noted that migratory butterflies 
are returning earlier in the spring and that polar bears along the 
province's Hudson Bay coastline are getting thinner because the sea 
ice is melting earlier, giving the animals less time to fatten up on 
seals, their main prey. 

Why is all this happening? There could be many explanations, but the 
common thread through all the occurrences is that Canada's climate 
has been getting warmer.  

That climate change might happen some day is hardly controversial. 
Humans are adding more carbon dioxide and other planet-warming gases 
to the atmosphere every year. Since the start of the Industrial 
Revolution, concentrations of CO{-2}, the main greenhouse gas, have 
risen by about 30 per cent, but they will double by the end of this 
century if usage trends for fossil fuels continue. 

Scientific models suggest that human-induced changes to the 
composition of the atmosphere will almost certainly cause 
temperatures to rise substantially over the next 50 to 100 years. 

But on the eve of another Earth Day, Canadians might want to consider 
something more radical on the subject of global warming -- directly 
from their own backyards. Warming should not be considered an 
abstraction due to occur at some vague point in the country's future. 
It has already arrived, and has been under way for the past few 
decades. 

A group of federal and provincial scientists have concluded that 
global warming has had a profound influence on Canada after 
completing the most exhaustive review ever undertaken of the hundreds 
of studies on the country's climate trends. They looked at reports of 
unusual wildlife sightings, such as Mr. Babaluk's salmon, the extent 
of glaciers on the Rockies and data from weather stations going back 
more than a century. 

Except for small parts of the Northeast that have actually become 
cooler of late, the warming is almost universal -- and not 
necessarily just a momentary blip. "There are really strong 
indicators that the climate is changing," says Environment Canada's 
Linda Mortsch, the scientist co-ordinating the effort, "and I think 
Canadians should be aware of that." 

That is why the researchers summarized their findings in a 45-page 
report, published by the Canadian Council of Ministers of the 
Environment and made public recently.  

The publication has not prompted the interest normally associated 
with a major environmental review because the Winnipeg-based council, 
which includes the federal, provincial and territorial environment 
ministers, is little known outside environmental-policy circles. (It 
normally works on such technical issues as the question of whether 
Canada should regulate mercury emissions from power-plant 
smokestacks.) 

The climate change has been most dramatic in the North. The Mackenzie 
Basin is now an average of two degrees warmer than it was in the 
early 1950s, even though parts of Labrador, northern Quebec and 
Baffin Island have grown cooler. 

But the best long-term temperature data are for the South, and the 
report reveals that all of Canada below the line formed by the 
northern boundaries of British Columbia, Alberta, Saskatchewan and 
Manitoba has become warmer over the past 100 years. 

In fact, the average increase of 0.9 degrees in Southern Canada is 
about 50 per cent larger than the rise that has occurred elsewhere on 
the planet, making this country a global-warming hot spot. 

This has played out in some major temperature shifts. 

In Whitehorse, for instance, Environment Canada figures show that the 
Yukon community used to have an average of 63 bone-chilling days a 
year during the 1950s and 1960s when the mercury plunged to minus 20 
or lower. By the 1980s and 1990s, that number had fallen to 49. The 
same trend occurred in Yellowknife, where the number of extremely 
cold days has fallen to an average of 108 a year from 121. 

And even though 0.9 degrees of warming may appear small -- it's below 
the amount humans can feel through our senses -- it has had some 
staggering environmental consequences. 

There has been a huge increase in frost-free periods each year, as 
many gardeners probably suspect. In some areas, such as central B.C., 
the span between the last frost in spring and the first freeze has 
grown by a stunning 50 days over the past century, with healthy 
increases also recorded on the Prairies and in Southern Ontario, 
Quebec and the Maritimes. 

The growing season is increasing mainly because the last spring 
frosts are happening a little earlier each year -- a direct result of 
nighttime temperatures that aren't falling as much as they used to.

But gardeners shouldn't expect to plant tropical varieties any time 
soon because the trend is unlikely to go on forever, says Joan 
Klaassen, a climatologist at Environment Canada who has researched 
the subject. 

"Eventually, we would have no winter," she says, plus the length of 
the frost-free period is volatile. As recently as 1980, for instance, 
Ottawa had its shortest growing season on record -- a mere 110 days, 
compared with the maximum of 182 days posted in 1990. 

However, if the fluctuations are smoothed out, the frost-free period 
has expanded by about 30 days since 1939. 

The trembling aspen, one of Canada's most common trees, grows in all 
forested regions, and when springtime temperatures rise enough, it 
goes into bloom. Aspens don't produce pretty flowers, but their date 
of first bloom is like a weathervane pointing to dramatic global 
warming. 

In Edmonton, researchers at the University of Alberta have been 
reviewing observations on the first flowering dates for the trees 
from 1901 to 1997, and have found a huge change.  

While the trees went into bloom in early May at the beginning of 
thelast century, by its end, the average date had advanced by nearly 
a month -- 26 days -- to early April. 

In the list of planetary threats, warming comes at the top, or close 
to the top, of any motivating factors for Earth Day. Working to 
preserve endangered species, cleaning up parks, and planting trees -- 
typical April 22 activities embraced by thousands of Canadians -- 
won't mean much if the climate changes so dramatically that it plays 
havoc with the planet. 

On paper, Canada has a good position on global warming. It has 
endorsed the Kyoto Protocol and Prime Minister Paul Martin said in 
February's Speech from the Throne that his government has unequivocal 
support for the international pact to cut emissions of planet-warming 
gases. 

But the glaring weakness in the government's commitment is that it 
hasn't fully explained how the country will meet the mind-boggling 
240 million tonnes of emission cuts required to comply with the 
treaty. 

(To put the challenge of this abstract tonnage figure in perspective, 
a typical car produces about four tonnes of CO{-2} a year.)

One of the big worries about global warming is that melting Antarctic 
and Arctic ice will cause sea levels to rise, inundating low-lying 
coastal areas. 

Canada has the world's longest coastline, making it especially 
vulnerable to flooding. 

For example, much of Charlottetown lies only a few metres above sea 
level, and over the past century, the ocean has been slowly rising up 
against the picturesque city. 

The total increase -- 30 centimetres -- means that now even small 
storms maybe able to produce enough of a surge at high tide to cause 
extensive damage. Researchers believe that about one-third of the 
rise at Charlottetown has been caused by global warming and the rest 
from land subsiding since the last ice age. 

Other areas at risk include parts of the Gasp� and the �les-de-la-
Madeleine in Quebec, along with parts of the Beaufort Sea coastline 
in the Arctic. 

Most of British Columbia will be less affected by higher sea levels 
because of its steep and rocky coastline, although low-lying areas, 
such as the highly populated Fraser Delta, are vulnerable. 

Another dramatic sign of global warming is in Canada's extensive 
glaciers and ice fields. Although not well known, this country has 
more glacial ice coverage -- 200,000 square kilometres -- than any 
place in the world, other than Antarctica and Greenland. 

The area of the most rapid warming in Canada in the past 50 years has 
been the West, and this heat has been cutting a swath through 
glaciers. There are about 1,300 glaciers on the eastern slopes of the 
Rockies, and they are 25 to 75 per cent smaller than in 1850.

Elsewhere, alpine ice patches -- in reality, mini-glaciers -- have 
been melting so rapidly from Yukon mountain ridges that archeologists 
are having trouble keeping up with all the ancient artifacts being 
exposed before these materials, such as carvings, wooden darts and 
leather pouches, succumb to rot. 

A much bigger problem is that many major Prairie rivers are fed by 
glaciers, so cities such as Edmonton, Calgary and Saskatoon may face 
a thirsty future. Recent surveys have found that the amount of 
glacier water feeding the Saskatchewan, the largest prairie river, 
has already begun to drop.  

The arrival of salmon in the Arctic prompted a lot of head scratching 
at the federal Fisheries Department, and led to an investigation. Was 
the sighting a result of global warming or just wanderlust? 

The salmon have kept coming since 1993 -- several were found last 
year -- but researchers also have gone through historical records and 
found sporadic visitations in the past. 

Federal fisheries scientist Sam Stephenson has studied the situation 
and says he still isn't sure whether the salmon are just looking for 
new territory to conquer or have been pushed north by warmer water 
temperatures in the south. "I would be hesitant to say global warming 
at this stage," he says, adding that "certainly, this is something 
that bears watching." 

However, something happening on neighbouring Victoria Island is even 
more difficult to explain. Mark Ekootak, a wildlife officer for the 
Northwest Territories government, was surprised by the recent arrival 
of something "I've never seen growing up" on the barren tundra.  

Only by consulting a field guide did he finally figure out that he 
had a tree swallow on his hands -- a bit odd considering that the 
tree line lies 750 kilometres to the south.

requirements have fallen notably in recent years while the demand for 
air conditioning has risen. 

Charlottetown - Over the past century, the sea level at the city has 
risen by nearly 30 centimetres, increasing the risk of flooding 
during a storm.    

The Great Lakes and Great Plains Regions

A major climate analysis for the Great Lakes region of the U.S. was
published in April 2003 by the Union of Concerned Scientists (UCS):
"Confronting Climate Change in the Great Lakes Regions". Written by 9
noted science professors of major Midwest universities, this study found
that in just the past 4 years (1998-2001), annual average temperatures in
the Great Lakes region exceeded the long-term temperature averages at the
various stations by 2 to 4 degrees F, and that average winter month
temperatures for the region were up to 7 degrees F above their long-term
averages at those stations.

The study also noted that the occurrence of the last spring freeze in the
Great Lakes region has been happening progressively earlier in the year,
with the current freeze date being an average of one week earlier than at
the beginning of the 1900s, and that growing seasons have
also begun to lengthen. 

Declines in Great Lakes surface water levels -- predicted with global
warming because reduce ice cover on the lakes will cause more evaporation
-- have been of particular concern to commercial shipping interests using
the Great Lakes. 

The study found that over the past five decades, the frequency of 24-hour
and 7-day intense rainfall events -- which result in flooding of stream
and rivers -- has been higher relative the long term average in the Great
Lakes. Global warming allows the air to hold on to more water at a time,
but then when it rains, it rains hard and ends up running off land
surfaces faster, and not soaking long enough into the ground.

Average temperatures for January and February in the U.S. during the
period 1998 to 2003 were significantly warmer (in those regions) than the
historical average temperature of those regions for January and February.

In computing five-year annual temperatures averages recorded at 26 NOAA
cooperative climate Great Lakes region stations during 1998-2000, Neuman
cited increases similar to those identified in the UCS study in
temperature. In analyzing annual temperature data at climate stations in
the Great Lakes States, he showed that above average annual temperatures
occurred from the 1920s through the 1950s and from the 1980s through the
year 2002. He noted also that average five year annual temperatures for
1998-2002 were the highest of record at many NWS cooperative climate
stations. 

The 1998-2002 temperature averages for the Great Lakes region exceeded
the long-term average temperature records at the various stations by 2.2
degrees F, with a range of increase from 1.1 to 3.6 degrees F above the
long-term temperature average for each station. [Reported in "Special
Report - Air Temperatures & Dew Points - Great Lakes States", April 16,

Wisconsin

Five-year 1998-2002 temperature averages for Broadhead, Marshfield,
Oconto, Portage, Sturgeon Bay, Spooner, Watertown and Weyerhaeuser
weather stations exceeded their long-term temperature records at the
stations by 2.3 degree F, with a range of increase from 1.4 at Oconto to
an increase of 3.6 degrees at Spooner, Wisconsin. 

Five-year (1998-2002) temperature averages for airport weather stations
located at Eau Claire, Green Bay, La Crosse, Madison and Milwaukee were
2.8, 2.3, 2.5, 2.2, and 2.5 degrees F (respectively) above their
"long-term" (before 1950 - 1997) temperature averages at each of those
stations (average of 2.3 above long-term averages). 

High humidity levels are often associated with high temperature readings
in Wisconsin and elsewhere in the Great Lakes region, most commonly
during the months of July and August. The dew point temperature (the air
temperature at which dew begins to form), is often used as a measure of
the amount of moisture in the air relative to the air's capacity to hold
moisture. 

Global warming models predict there will be rising dew point levels with
continued global warming. Measurable increases in average dew point
temperatures in 1998-2002 occurred in Eau Claire, Green Bay, La Crosse,
Madison and Milwaukee, Wisconsin, according to Neuman's "Special Report -
Air Temperatures & Dew Points - Great Lakes States". During the last 5
years of dew point measurements at the above stations, average annual dew
point temperatures records exceeded the average dew point levels at those
stations over the period of 1950 to 1997 by 2.7, 2.9, 2.2 and 2.5 degrees
F, respectively.

The rising average dew point temperatures for the Midwest make any
periods of hot weather in Wisconsin and the Midwest more dangerous to
human health. 

A heat wave in 1995 claimed the lives of 154 Wisconsinites and forced
another 400 people to seek medical treatment. (739 people died in Chicago
from the same weather pattern). The 1995 heat wave holds the record as
the number one weather-related killer in Wisconsin since Wisconsin became
a state in 1848. 

In 1999, at least 20 people in Wisconsin died from the effects of heat;
in 2001, 15 people died from heat-related effects; and in 2002, the
number was 8. 

Madison, Wisconsin's Lake's Monona and Mendota provide an interesting
history of the effects that warmer winter temperature can have on local
winter activities.

On Lake Mendota, the largest and deepest of the two lakes, the average
duration of ice cover has decreased from about four months in the
mid-1800s to about three month by the late 1990s. While ice duration has
declined over the past 80 years on North Temperate Zone lakes, according
to University of Wisconsin Limnologist professor Emeritus John Magnuson,
the last 20 years has seen the most rapid reduction. Lake Mendota ice
duration record illustrates that trend.

The most extreme change for Lake Mendota came in the winter months of
2001-2002, when the lake had the shortest ice duration observed since
1853, and ice cover lasted only 21 days. Magunson says the mean duration
of ice cover has been declining on Madison's Lake Monona as well, from
114 days of ice cover in the 1870s, to an average of 82 days in the
1990s.

Royal Gazette)

Much of Europe and several Asian countries last summer experienced deadly
heat wavers during certain months of the summer. Upwards of 35,000
Europeans lost their lives as a result of an extreme heat wave that hit
most of Europe early last August; heat wave deaths were reported in
France, Switzerland and the Mediterranean region, killing upwards of
35,000 people, with 15,000 deaths from the heat reported in France alone.
http://www.earth-policy.org/Updates/Update29.htm

An acute heat wave took the lives of at least 1,065 people in the
southern Indian state of Andhra Pradesh, which exceeded the heat wave
death toll that occurred in 2002, when another 1,037 people lost their
lives as a result of record high temperatures during the daytime and
nighttime hours. 

The coastal regions of Andhra and Telangana experienced temperatures
almost 10 degrees higher than the seasonal average last summer. 
http://www.ncdc.noaa.gov/oa/climate/research/2003/ann/global.html#Ttrends

The NCDC summary report on 2003 for the Southern Hemisphere does not
document any heat wave deaths. That does not rule out there having been
some, of course. The Southern Hemisphere's experiences summer and winter
during the opposite times of the year from the Northern Hemisphere, and
that may influence the availability of heat wave death reports.

Arctic Circle, Antarctica and Mountain Tops

Two of the more obvious signs of global warming are: (1) rates of ice and
snow melting increase over the year, and (2) the geographic extent
(acres) of snow and ice melting increases from year to year. 

In both 2002 and 2003, the Northern Hemisphere registered record low
ocean ice cover. NASA's satellite data show the Arctic region warmed more
during the 1990s than during the 1980s, with Arctic Sea ice now melting
by up to 15 percent per decade. Satellite images show the ice cap
covering the Northern pole has been shrinking by 10 percent per decade
over the past 25 years. 

On the opposite end of the globe, sea ice floating near Antarctica has
shrunk by some 20 percent since 1950. One of the world's largest
icebergs, named B-15, that measured near
10,000 square kilometers (4,000 square miles) or half the size of New
Jersey, calved off the Ross Ice Shelf in March 2000. The Larsen Ice Shelf
has largely disintegrated within the last decade, shrinking to 40 percent
of its previously stable size. 
http://cooltech.iafrica.com/science/280851.htm

Ice cores drilled through a glacier more than four miles up in the
Himalayan Mountains have yielded a highly detailed record of the last
1,000 years of earth's climate in the high Tibetan Plateau. Based on an
analysis of the ice, both the last decade and the last 50 years were the
warmest in 1,000 years.

http://www.senate.gov/~gov_affairs/071801_karl.htm

On Greenland, once-stable glaciers are now melting. The Jakobshavn
Glacier on the island's southwest coast is thinning four times faster now
than it did during most of the twentieth century. Each year, Greenland
loses some 51 cubic kilometers of ice, enough to annually raise sea level
0.13 millimeters. [Glacial ice melting when it occurs on land adds "new"
water to the ocean, whereas the melting of sea ice does not cause any
increase in sea level since the water is already present in or on the
ocean.]

Glaciers in Central Asia's Tien Shan Mountains have shrunk by nearly 30
percent between 1955 and 1990. In arid western China, shrinking glaciers
account for at least 10 percent of freshwater supplies. The retreat of
the Qori Kalis Glacier in the northern Andes has accelerated to 155
meters a year between 1998 and 2000, which is three times faster the
retreat that occurred during the previous three-year period. 

The Antizana Glacier in Ecuador has retreated more than 90 meters over
the last eight years. The Chacaltaya Glacier near La Paz, Bolivia, melted
to 7 percent of its 1940s volume by 1998. 

Scientists say glaciers are melting so fast in parts of Kazakhstan that
the livelihoods of millions of people will be affected. Mountains which
run for 1,250 miles along the north-west edge of the Tibetan plateau form
an important climatic barrier between the Siberian and central Asian air
masses. There are 416 glaciers in the region, covering 197 square miles.
Between 1974 and 1990, these glaciers lost 1.28% of their volume, each
year.
http://news.bbc.co.uk/go/pr/fr/-/2/hi/science/nature/3077422.stm

The Patagonia Icefields of Chile and Argentina, the largest non-Antarctic
ice masses in the Southern Hemisphere, are thinning at an accelerating
pace and now account for nearly 10 percent of global sea-level change
from mountain glaciers, according to a new study by NASA and Chile's
Centro de Estudios Cientificos.

The Patagonia Icefields (2,140 sq. mi.) lost ice at a rate equivalent to
a sea level rise of 0.04 millimeters per year during the period 1975
through 2000. This is equal to nine percent of the total annual global
sea-level rise from mountain glaciers, according to the 2001
Intergovernmental Panel on Climate Change Scientific Assessment. From
1995 through 2000, however, that rate of ice loss from the icefields more
than doubled, to an equivalent sea level rise of 0.1 millimeters per
year. 
http://www.jpl.nasa.gov/releases/2003/138.cfm

Africa's glaciers are also disappearing. Across the continent, mountain
glaciers have shrunk to one-third their size over the twentieth century.
On Kenya's Kilimanjaro, ice cover has shrunk by more than 33 percent
since 1989. In Western Europe, the glacial area has shrunk by up to 40
percent, and glacial ice has declined in volume by more than half since
1850. 

Glacier National Park in Montana has lost over two thirds of its glaciers
since 1850. Glaciers in all of Alaska's 11 glaciated mountain ranges are
shrinking. Since the mid-1990s, Alaskan glaciers have been thinning by
1.8 meters a year, more than three times as fast as during the preceding
40 years.
http://www.earth-policy.org/Updates/Update32.htm

Researchers at the University of Alaska recently surveyed 67 major
glaciers and found the rate of melting in the last five years is rapidly
growing. From the mid-1950s to the mid-1990s, the glaciers lost about 13
cubic miles of ice a year to the ocean; in the last 5 years, the annual
rate of ice lost increased almost 100% to 24 cubic miles. Over the last
half of century, approximately 500 cubic miles of ice have melted off the
67 Alaskan glaciers studied.

This summer saw the biggest melt yet in Alaska's sea ice, and winter in
the interior was unprecedentedly mild - for the Arctic. 

NCDC's latest report finds that "much warmer than average temperatures
were widespread across much of Alaska last year", that the spring snow
cover extent in the Northern
Hemisphere again measured below average, with 14 of the last
16 years in the Northern Hemisphere having below average spring snow
cover extent. 

The beetle boom in Alaska is one that locals and scientists alike
attribute to global warming. But it's just one in a long list. Some say
temperatures have changed more in Alaska over the past 30 years than they
