Oral
Statement By
DR.
JOHN T. EVERETT
HEARING ON
WILDLIFE
AND OCEANS IN A CHANGING CLIMATE
BEFORE THE
COMMITTEE ON NATURAL
RESOURCES
SUBCOMMITTEE ON
FISHERIES, WILDLIFE AND OCEANS
U.S. HOUSE OF
REPRESENTATIVES
April 17, 2007
Madam Chairwoman and Members of
the Committee, thank you for inviting me.
My written statement presents the
results of the work I led for the Intergovernmental Panel on Climate Change
from 1988 to 2000. This is still the most thorough, comprehensive, and broadly
reviewed work on the oceans and fisheries subjects that has been published. I led IPCC work on five impact analyses: Fisheries
(Convening Lead Author), Polar Regions (Co-Chair), Oceans (Lead Author), and
Oceans and Coastal Zones (Co-Chair/2 reports).
In
1996 I received the NOAA Administrator’s Award for “accomplishments in
assessing the impacts of climate change on global oceans and fisheries.”
Since
leaving NOAA, I have been an IPCC reviewer and have talked to many individuals
and groups and have maintained these subjects on the UN Atlas of the Oceans (http://www.OceansAtlas.org), where I am
the Chief Editor and Project Manager.
Professionally,
I am also President of Ocean Associates, Inc. (http://www.OceanAssoc.com), an oceans and
fisheries consulting business, and two web-based businesses: http://www.OceansArt.us sells and shares
ocean-related photos, while http://www.TechnologySite.org
provides information and photos about inventions. Lastly, I have a website
where I try to keep track of all the latest information about the soldiers in
the climate change wars: http://www.ClimateChangeFacts.info.
Madam
Chairwoman, It is time for a reality check.
The
oceans and coastal zones have been far warmer and colder than is projected in
the present scenarios of climate change. Over millennia, marine life have
endured and responded to CO2 levels well beyond anything projected, and
temperature changes that put coral reefs and tropical plants closer to the
poles or had much of our land covered by ice more than a mile thick. The memory
of these events is built into the genetic plasticity of the species on this
planet. Biological impacts will be determined by this plasticity and the resiliency
of organisms to find suitable habitats. In the oceans, major climate warming
and cooling is a fact of life, whether it is over a few years as in an El Niño
or over decades as in the Pacific Decadal Oscillation or the North Atlantic
Oscillation. Currents, temperatures, salinity, and biology changes rapidly to
the new state in months or a couple years. These changes far exceed those
expected with global warming and occur much faster. The one degree F. rise
since about 1860, indeed since the year 1000, has brought the global average
temperature from 56.5 to 57.5 degrees. This is at the level of noise in this
rapidly changing system.
Sea
level has been rising since the last glaciation lost its grip, and temperatures
rose by 10-20 degrees, a mere 10,000 years ago. It is only some few thousand
years since Georges Bank was part of the mainland. It is now 60 miles offshore
of Provincetown. Its trees and the shells of its oysters that flourished on its
shores still come up in dredges and trawls in now deep water, with the oysters
looking like they were shucked yesterday. In the face of all these natural
changes, and those we are here to consider, some species flourish while others
diminish. These considerations were well understood in all the IPCC groups in
which I participated.
I
have some concerns about some few species near the margins of their suitable
habitat range, such as polar bears.
But I would much rather have the present warm climate, and even further
warming, than the next ice age that will bring temperatures much colder than
even today.
The
NOAA PaleoClimate Program shows us that when the dinosaurs roamed the earth,
the earth was much warmer, the CO2 levels were 2 to 4 times higher, and coral reefs
were much more expansive. The earth was so productive then that we are still
using the oil, coal, and gas it generated.
More
of the warming, if it comes, will be during winters and at night and toward the
poles. For most life in the oceans,
warming means faster growth, reduced energy requirements to stay warm, lower
winter mortalities, and wider ranges of distribution.
Warming
is not a big deal and is not a bad thing.
No
one knows whether the Earth is going to keep warming, or since reaching a peak
in 1998, we are at the start of a cooling cycle that will last several decades
or more. Whichever it is, our actions should be prudent. Our fishing and maritime
industries compete in a world market and are vulnerable to government actions
to reduce CO2 emissions. We already import most of our seafood and our
competitors do not need further advantages. Our ocean research should focus on
things we need to know to wisely manage our resources, industries, and coastal
areas, no matter which way the wind blows in the years to come.
I
would be pleased to answer questions.
