In case you missed it, here are highlights from Michelle Obama's speech at the Democratic National Convention last night.
Oregon Wild will previw the new documentary film A Fierce Green Fire: the Battle for a Living Planet at 6:30 pm Wednesday, Sept. 5, at the Knight Law Center, Room 110 at UO.
A commentary by Edward Hershey in the Blue Oregon blog this week notes that The Oregonian will not be endorsing a presidential candidate this election for the first time, maybe ever. Why?
Hershey writes: “This is about pragmatism, not philosophy. What is most likely at play here is that the two men now driving editorial policy at the O — publisher Chris Anderson and editorial page editor Erik Lukens — understand it would be bad business to endorse Romney. But both would just about die rather die than endorse Obama.”
Can Eugene and Springfield learn anything about growing more compactly from Seattle’s successes and failures? Tara Sulzen, outreach director for 1000 Friends of Oregon, attended the Urban Land Institute Northwest Young Leaders Regional Conference in Seattle in early August and wrote about it the latest 1000 Friends newsletter. She also picked up some insights from noted political thinker Matthew Yglesias at a Bus Project event in Portland. Check out her report at:
A candlelight prayer vigil to remember the victims of the tragic shooting at a Sikh temple near Milwaukee, Wisc., will be from 7 to 8 pm Wednesday, Aug. 8, at Tugman Park, 36th Place and Hilyard in Eugene. The local Eugene Sikh community is inviting the greater Eugene/Springfield communities to join them.
The vigil is “to remember the victims of the tragic shooting at the Sikh temple in Wisconsin, to honor the bravery of the police officers who responded, and to stand for peace and understanding amongst all human beings,” according to an email from Gurumukh S. Khalsa. This vigil will be held in conjunction with other vigils across the nation.
Sikh prayers will be shared, a moment of silence, and words of peace may be offered. Bring blankets and a candle to light. Tea and refreshments will be served.
Architect Mark Lakeman will speak about Opportunity Village Eugene in a talk called "Let's Do It Right" from 7 to 9 pm Tuesday, Aug. 14, at the new Unitarian Universalist Church, 1685 W. 13th Ave. in Eugene. This video is from an earlier talk.
The chronic drought that hit western North America from 2000 to 2004 left dying forests and depleted river basins in its wake and was the strongest in 800 years, scientists have concluded, but they say those conditions will become the “new normal” for most of the coming century, according to a press release from Oregon State University. Here is the rest of the statement by David Stauth at OSU:
Such climatic extremes have increased as a result of global warming, a group of 10 researchers reported today in Nature Geoscience. And as bad as conditions were during the 2000-04 drought, they may eventually be seen as the good old days.
Climate models and precipitation projections indicate this period will actually be closer to the “wet end” of a drier hydroclimate during the last half of the 21st century, scientists said.
Aside from its impact on forests, crops, rivers and water tables, the drought also cut carbon sequestration by an average of 51 percent in a massive region of the western United States, Canada and Mexico, although some areas were hit much harder than others. As vegetation withered, this released more carbon dioxide into the atmosphere, with the effect of amplifying global warming.
“Climatic extremes such as this will cause more large-scale droughts and forest mortality, and the ability of vegetation to sequester carbon is going to decline,” said Beverly Law, a co-author of the study, professor of global change biology and terrestrial systems science in the College of Forestry at OSU, and former science director of AmeriFlux, an ecosystem observation network.
“During this drought, carbon sequestration from this region was reduced by half,” Law said. “That’s a huge drop. And if global carbon emissions don’t come down, the future will be even worse.”
This research was supported by the National Science Foundation, NASA, U.S. Department of Energy, and other agencies. The lead author was Christopher Schwalm at Northern Arizona University. Other collaborators were from the University of Colorado, University of California at Berkeley, University of British Columbia, San Diego State University, and other institutions.
It’s not clear whether or not the current drought in theMidwest, now being called one of the worst since the Dust Bowl, is related to these same forces, Law said. This study did not address that, and there are some climate mechanisms in western North America that affect that region more than other parts of the country.
But in the West, this multi-year drought was unlike anything seen in many centuries, based on tree ring data. The last two periods with drought events of similar severity were in the Middle Ages, from 977-981 and 1146-1151. The 2000-04 drought affected precipitation, soil moisture, river levels, crops, forests and grasslands.
Ordinarily, Law said, the land sink in North America is able to sequester the equivalent of about 30 percent of the carbon emitted into the atmosphere by the use of fossil fuels in the same region. However, based on projected changes in precipitation and drought severity, scientists said that this carbon sink, at least in western North America, could disappear by the end of the century.
“Areas that are already dry in the West are expected to get drier,” Law said. “We expect more extremes. And it’s these extreme periods that can really cause ecosystem damage, lead to climate-induced mortality of forests, and may cause some areas to convert from forest into shrublands or grassland.”
During the 2000-04 drought, runoff in the upperColorado River basin was cut in half. Crop productivity in much of the West fell 5 percent. The productivity of forests and grasslands declined, along with snowpacks. Evapotranspiration decreased the most in evergreen needleleaf forests, about 33 percent.
The effects are driven by human-caused increases in temperature, with associated lower soil moisture and decreased runoff in all major water basins of the western U.S., researchers said in the study.
Although regional precipitations patterns are difficult to forecast, researchers in this report said that climate models are underestimating the extent and severity of drought, compared to actual observations. They say the situation will continue to worsen, and that 80 of the 95 years from 2006 to 2100 will have precipitation levels as low as, or lower than, this “turn of the century” drought from 2000-04.
“Towards the latter half of the 21st century the precipitation regime associated with the turn of the century drought will represent an outlier of extreme wetness,” the scientists wrote in this study.
These long-term trends are consistent with a 21st century “megadrought,” they said.
