What climate is & what climate change means

[Source: Holdren 2008]

Climate is the pattern of weather, meaning averages,

extremes, timing, spatial distribution of…

  • hot & cold
  • cloudy & clear
  • humid & dry
  • drizzles & downpours
  • snowfall, snowpack, & snowmelt
  • zephyrs, blizzards, tornadoes, & typhoons

Climate change means altered patterns.

[Changes in globally averaged temperature are one measure of GCC. Other measures will include items listed above. Small changes in the index  big changes in the patterns.]

Climate governs (so climate change affects)

  • availability of water
  • productivity of farms, forests, & fisheries
  • prevalence of oppressive heat & humidity
  • formation & dispersion of air pollutants
  • geography of disease
  • damages from storms, floods, droughts, wildfires
  • property losses from sea-level rise
  • expenditures on engineered environments
  • distribution & abundance of species
why climate change is a fact
Why Climate Change is a Fact
  • The earth is getting hotter, both land and ocean.
  • Atmospheric circulation patterns are changing.
  • Permafrost is thawing.
  • Arctic summer sea ice is thawing.
  • Surface melting on Greenland is expanding.
  • Sea level is rising.
  • All of the above are forced by human emissions of Green House Gases (GHG) over last 250 years (IPCC, 2007).

  • Evaluate current and proposed actions to reduce CO2 emissions
  • Make recommendations on improved preparedness and adaptation, including climate change impacts assessment in cooperation with UW Climate Impacts Group

Objectives of the Impacts Assessment

Evaluate impacts of climate change for the 21st century

  • use IPCC 2007 climate scenarios
  • show regional impacts and areas of high and low sensitivity to climate change
  • characterize barriers to adaptation to these impacts (e.g., legal, institutional)
  • provide tools for policy makers and user groups
  • collaborate with Governor’s Climate Change Challenge team

what is significant about this project
What is Significant about This Project?
  • Large scope & sector diversity. (Atmosphere, ocean, mountains, water, fish, trees, wheat, potatoes, apples, people and their $ all in a single package).
  • Very high level of integration achieved.
  • Use of ensemble of 20 climate models narrows uncertainty to considerable extent.
  • Projected ranges of impacts at different locations and in different ecosystems quantified.
  • First time data products of such fine resolution will be freely available on the internet in such an integrated fashion.
How, in general, the project was conducted:
    • downscale global climate scenarios to regional scenarios, feed those results into VIC and DHSVM, feed those results into forest, agriculture, stormwater, energy, health models)
