Home Science Climate Lessening fog may hurt California redwoods
Fog has been decreasing during the summer months along the Pacific coast of the United States. According to new U.S. research, this climate change over the past century may be hurting the California redwood trees.



The 2.15.2010 Mongabay.com article 'Decline in fog threatens California's iconic redwood ecosystems' states, 'A surprising new study finds that during the past century the frequency of fog along California's coast has declined by approximately three hours a day'¦. [T]he researchers are concerned that this decrease in fog threatens California's giant redwoods and the unique ecosystem they inhabit.'

U.S. environmental scientists James Johnstone and Todd Dawson, both from the University of California at Berkeley, have been studying summer fog along the Pacific coast of the United States with respect to its affect on the California redwood.

Johnstone is a postdoctoral scholar at UC-Berkeley's Department of Environmental Science, Policy and Management (ESPM).

Their paper, titled 'Context and ecological implications of summer fog decline in the coast redwood region" appears in the journal Proceedings of the National Academies of Science (PNAS).

They identified a 33% decrease in the frequency of fog along the California coast between the years 1901 to 2008.

Native to this area in coastal California is the California redwood (Sequoia sempervirens, or coast redwood).

VMware changed the rules about the server resources required to keep a database responding

It's now more difficult for DBAs to see interaction between the database and server resources

This whitepaper highlights the key differences between performance management between physical and virtual servers, and maps out the five most common trouble spots when moving production databases to VMware

1. Innacurate metrics
2. Dynamic resource allocation
3. No control over Host Resources
4. Limited DBA visibility
5. Mutual ignorance

Don't move your database to VMware before learning about these potential risks, download this FREE Whitepaper now!
