Local warming

Pacific Northwest says goodbye to salmon, skiing; hello to heat waves 3

The new U.S. climate change impacts report—on which we’ve been reporting all day—includes some hard-hitting regional data.

For example, did you know that annual average temperatures in the Northwest rose about 1.5 degrees Fahrenheit over the last century—with some areas seeing increases up to 4 degrees? And the rising mercury ain’t slowing any time soon: average temps are predicted to rise another 3-10 degrees in this century.

That may not sound too bad to those of us craving some summer warmth. But it’s scary news if you’re a local salmon craving cold water—or a ski bum craving cold snow, for that matter.

How else will rising CO2 emissions (and rising temperatures) affect our region? Here are some highlights (low lights?) from the report:

  • Declining springtime snowpack leads to reduced summer streamflows, straining water supplies.
  • Increased insect outbreaks, wildfires, and changing species composition in forests will pose challenges for ecosystems and the forest products industry.
  • Salmon and other coldwater species will experience additional stresses as a result of rising water temperatures and declining summer streamflows.
  • The projected reduction in snow cover will adversely affect winter recreation and the industries that rely upon it.
  • Sea-level rise along vulnerable coastlines will result in increased erosion and the loss of land. (See scary red image below.)

Map of sea-level rise in Puget SoundHighly populated coastal areas throughout Puget Sound, Wash., are vulnerable to sea-level rise. The maps show regions of Olympia and Harbor Island (both located in Puget Sound) that are likely to be lost to sea-level rise by the end of this century based on moderate and high estimates.

 

P.S. I’m focusing my anxiety on the Northwest regional data because, well, that’s where I live. But the news is bad all over ... check it out for yourself.

    me thinks right now WA has other problems to worry about ** WEATHER CAFE **
    Cooler spring delays harvest
    Growers note consistently low temperaturesDegree-days
    Cumulative degree days – 45 F minimum, 85 F maximum – from Jan. 1 through March 19 in the years designated.2007 2008 2009
    Bellingham 114 69 45
    Mount Vernon 133 84 58
    Wenatchee 69 64 18
    Yakima 106 101 48By COOKSON BEECHERCapital PressLate harvests may be in store for Washington state growers this year, according to reports from the field.Underscoring the field reports are comparisons of degree-days – also known as heat units – from the start of the year to March 19, which show fewer heat units this year than in 2008 or 2007.Rufus LaLone, an entomologist and meteorologist, said this year’s situation is worrisome because 2008 had the latest harvests in the region since 1984.“We’re way behind last year,” LaLone said. “It’s still early, but if March and April stay cold, we’ll really be behind.”According to LaLone’s Weather Cafe report on March 23, April 3 or 4 should see a return to a cold upper trough dropping down from the Gulf of Alaska bringing wet and unseasonably chilly conditions to the Pacific Northwest for several days. Eastern Washington basins will return to near-winter feel by early April, as cold air aloft will hinder spring. Possibly drier, but nippy weather, is forecast for April 8-12.Each plant needs a certain number of degree-days before it reaches the next stage of its development.LaLone compares degree-days to money in the bank.“If enough heat units are generated, the plants collect them,” LaLone said. “It’s like a savings account. They don’t forget what they’ve accumulated.”In Skagit County, Wash., William Roozen, co-owner of Washington Bulb, said the daffodils are later this year than last year, and the tulips may go into peak bloom later than usual. His brother John said that in an average year, daffodil harvest runs from Feb. 18 to 22, but this year picking didn’t start until early March.Many Western Washington farmers say that if the flowers are late, harvest for other crops will probably be late. But John Roozen said Mother Nature calls the shots.“If the weather warms up, the tulips can go like lightning,” he said.Skagit County, Wash., potato grower Darrin Morrison said he’s watching soil temperatures, which were still low on March 20.“It’s a late spring,” he said. “Even our orchard trees haven’t budded out yet.”In Whatcom County, Wash., Allen Brown, fieldman for Curt Maberry Farm, said that last year crews started the main fungicide spraying regime for blueberries on March 12.“We haven’t sprayed a single blueberry this year,” he said on March 20. “We’re probably three weeks behind last year.”Raspberry cane planting is also running late. While Maberry’s usually has all of its new raspberries in by March 20, the farm still had 90 acres to plant, and some growers in the area hadn’t planted any new canes.“We’ve had a lot of cold weather and freezing temperatures – 18 degrees for three days in a row a week or so ago,” Brown said. “It was like winter.”Brown said berry growers in his area are praying for sunshine.“We’re behind, and we want to get going,” he said. “We’re in a hurry-up-and-wait mode.”LAST YEAR was no great shakes either — Cherry and apples crops took a hit due to unseasonable cold. seehttp://seattle.bizjournals.com/seattle/stories/2008/06/23/story4.html

    Interesting. That site only talks about increasing heat and doesn't explain the weather anomalies the Northeast is experiencing right now, in terms of another cool wet spring (3rd in a row: sad tomato plants abound) - and it's still going - leaving everyone craving summer weather. Soggy. Here at the Orion magazine office we're starting to call it the Pacific Northeast.So maybe that's the deal, Sarah: we got your weather now, you got ours. Climate change is just that: change everywhere of all kinds, even cooler weather sometimes. - Erik, Orion Grassroots Network

    Goog point Erik.  I with I could find the link at my fingertips, but there are NOAA maps of "departure from climactic" termperature maps of the globe that show what you mean very simply and intuitively.  The rapid warming of certain areas in northern Alaska and northern Siberia are the most obvious features -- it looks as if on fire!  True, the same map also shows cooler blue temperatures over the northern tier of the US, very observant.  The rest of the globe appears to be covered in light pink, meaning constantly warming temperatures -- although there are a few interesting spots where anomalies and cooling exists. The Bahamas, for example, appear to be in a cooling phase of sorts.So my point is that the world will not warm 10 to 11 degrees everywhere, spread across the board.  This is impossible from a thermodynamic perspective.  I'm sure no scientist would claim this other than to say that mean global average temperatures could climb 10 to 11 degrees over the next century, based on what we know today and how our models work.  A global mean really doesn't say anything about a specific spot on the Earth.
