The Greatest ThreatThe Greatest Threat

“There is no doubt in my mind that climate change is one of the greatest threats facing humanity today.”

“Things are getting desperate enough now that we need to throw away our conservatism and just act.”

What do these pollutants do? – Global Fever

Greenhouse gases make the earth too hot, just like:

> sleeping under a heavy blanket in the summertime

> wearing a parka that is too thick

Our atmospheric “blanket” or “parka” is over 35% “thicker” than it used to be

Thicker blanket traps too

much heat.

Thinner blanket is “just right.”

Weather vs. Climate

“Choosing shorts or long underwear on a particular day is about weather; the ratio of shorts to long underwear in the drawer is about climate.”

Charles Wohlforth ~ The Whale and the Supercomputer

20081950

Weather: The short-term state of the atmosphere -- up to a few days

Climate: Long-term averages, frequencies and extremes -- generally 3 to 5 decades

Melting Sea IceMelting Sea IceThe Arctic Ocean could be ice-free in summer by 2040.

(U.S National Center for Atmospheric Research 2006)

“Our research indicates that society can still minimize the impacts on Arctic ice.”

Dr. Marika Holland, National Center for Atmospheric Research

2000 2040

Page 19: Alaska PPT Slides

Impacts in Alaska1. Melting

The rapid retreat of Alaska’s glaciers represents 50% of the estimated mass loss by glaciers through 2004 worldwide (ACIA, 2004)

Loss of over 588 billion cubic yards from 1961 to 1998 (Climate Change, 11/05)

Alaska’s glaciers are responsible for at least 9% of the global sea level rise in the past century (ACIA, 2004)

Bering Glacier, representing more than 15% of all the ice in Alaska, is melting twice as fast as previously believed, releasing approximately 8 trillion gallons of water per year into the ocean -- or the equivalent of two Colorado Rivers (Michigan Tech Research Institute, 5/07)

Accelerated melting of glaciers and ice caps could add an additional 4 to 9.5 inches of sea level rise. (Science 7/07)

Alaska’s Columbia Glacier has decreased by approximately 9 miles since 1980 and thinned by as much as 1,300 feet.. (Science 7/07)

Shifting denning sites: 62% on ice (1985-94); 37% on ice (1998-2004) (Fischbach et al., 2007)

USGS predicts the extirpation of Alaska’s polar bears by 2050, with an overall elimination of two-thirds of the global population (USGS, 2007)

Due to warmer temperatures, the tree line in the Kenai Mountains has risen at a rate of about 1 meter/year over the past 50 years

20% of the tundra above 1,500 ft. has disappeared, is now shrub or open woodland (Refuge Notebook, 6/07)

Muskoxen Population in northern Alaska and

Canada declined from approximately 700 to 400 (Pat Reynolds, FWS, 2007)

Risk Factors:

• Icing events

• Lower calf production

• Deeper snow

• Not highly mobile

• Increase in disease (e.g. nematode

lungworm, able to complete life

cycle in 1 year v. 2 years) (Kutz et al., 2004)

Infrastructure Impacts in Alaska

4. Weather and Storms

“A warming climate will damage Alaska’s infrastructure because it was designed for a cold climate.” (Larsen and Goldsmith Institute of Social and Economic Research 6/07)

- Damage to infrastructure may add $3.6 to $6.1 billion (10% to 20%) to future costs for public infrastructure from now to 2030 and $5.6 to $7.6 billion (10% to 12%) from now to 2080.

- Damage will be concentrated in areas of thawing permafrost, flooding, and eroding coastlines.

Page 55: Alaska PPT Slides

Alaska’s Arctic Coast USGS documented

that in the last 50 years, a section of the Alaska North Slope coastline has eroded by as much as 3,000 ft (0.9 KM).

(Geology 07/07)

Erosion rates for the area increased from .48 km2/year (1955-1985) 1.08 km2/year (1985-2005). (Geology 07/07)

“…the Arctic is becoming an environment at risk… Sea ice is less stable, unusual weather patterns are occurring, vegetation cover is changing, and particular animals are no longer found in traditional hunting areas during specific seasons.

Local landscapes, seascapes, and icescapes are becoming unfamiliar, making people feel like

strangers in their own land.” (ACIA, 2004)

“For the Inuit, climate change is a matter of livelihood, food, health, and individual and cultural survival.”

“The erosion and potential destruction of our way of life brought about by climate change resulting from emission of greenhouse gases amounts to a violation of the fundamental human rights of Inuit.”

“Due to unusual ice conditions, one of our young local hunters lost his life, which has not

occurred in our community in my lifetime.” Fannie Weyiouanna, Shishmaref

“All of these villages have lost people on the ice. When you have a small village of 300 or 400 people, losing three or four of their senior hunters, it’s a big loss. A lot of the elders will no longer go out on the sea ice because their knowledge will not work anymore. What they’ve learned and passed on for 5,000 years is no longer functional.”

If we fail to act, and CO2 keeps rising at the current rate, then a new modeling study predicts that:

If we do not Act: Worst Case

PredictedTemperature

Increase

Average temperatures in many parts of northern North America will rise more than 25oF by 2100.

Arctic tundra will decline from 8% to 1.8% of the world’s land area, and Alaska will lose almost all of its evergreen boreal forests.

Extinctions and profound disruptions will ensue.

Measuring Your Carbon Footprint

Major Carbon Contributors:

Electric consumption

Gas/heating oil consumption

Car and miles driven

Miles flown

ORV use

Average Alaskan Carbon Footprint = 24,000 pounds

www.alaskaconservationsolutions.com

What We Can Do

Page 77: Alaska PPT Slides

Making a Difference as an IndividualConservation Measures:

Walk, bike, ride public transit, or carpool

Make sure your tires are fully inflated and your car tuned up Lower your water heater and

home thermostats Don't preheat your oven Only run your dishwasher with

full loads Reduce your shower length and temperature Buy locally produced food—look

for the Alaska Grown Logo Unplug appliances not in use Turn off lights when leaving a room Use recycled paper Reuse or recycle as much as you can Cut down on consumerism

What We Can Do

Page 78: Alaska PPT Slides

Conservation: Three ExamplesUnplug Appliances Vampires! 43 billion kWH lost/year in U.S. Estimated savings =

1,000 lbs/year/person

Pump Up Tires 4 million gallon of gas wasted

daily in U.S. Extends life of tires by 25% Estimated savings =

1,000 lbs/year/person

Lower Thermostat 2 degrees OR 6 degrees for 8 hours/day Estimated savings =

2000 lbs/year/person

What We Can Do

Page 79: Alaska PPT Slides

Making a Difference as an Individual

Energy Efficiency Reduce your home’s heat and

energy loses Replace incandescent lights with fluorescents Replace your appliances with “energy star” rated appliances Buy a hybrid car

Renewables Install renewable energy systems:

wind, solar, geothermal, in-stream hydro

Use biofuels

Carbon Neutral Carbon offsets – Denali Green Tags

Be Heard!

What We Can Do

Page 80: Alaska PPT Slides

Energy Efficiency: Two Examples

Compact Fluorescents Four to six times

more efficient Estimated savings =

100 lbs/year for each bulb converted

Hybrid Cars Save money on fuel Tax credit Estimated savings =

5,600 lbs/year

We are at ground zero.

We are the “Paul Revere” of global warming.

Alaska contributes in unique ways to the earth’s natural and cultural heritage, and this heritage is imperiled.

Our leaders matter.
