“Debris flows are common events that can shape stream habitat in
mountainous regions around the world, particularly in the rainy
Pacific Northwest. “A landslide, once in a stream, can create a
debris flow — a slurry of mud, rocks, and organic material that
scours sediment and wood along steep headwaters streams — and then
deposit this downstream in lower-gradient fish-bearing channels,”
explains Burnett. “But not all landslides enter streams and not all
debris flows travel to streams containing fish.”

First Nationwide Climate Change Survey of Public Health Departments
Shows Lack of Resources for Dealing with Health Challenge

WASHINGTON, DC – April 24 – Climate change is a concern to most local public health directors but few have resources to tackle the problem, according to a national survey conducted by National Association of County and City Health Officials (NACCHO), Environmental Defense Fund (EDF) and George Mason University.
The survey, included in the report Are We Ready? Preparing for the Public Health Challenges of Climate Change, is the first national one of its kind that assesses the perceptions and activities of local public health directors regarding climate change and public health.

FALSE SOLUTION: Sulphate Spraying Into Stratosphere

Plan to reverse global warming could backfire
Thu Apr 24, 2008 7:14pm EDT By Julie Steenhuysen

CHICAGO (Reuters) – A proposed solution to reverse the effects of global warming by spraying sulfate particles into Earth’s stratosphere could make matters much worse, climate researchers said on Thursday.

They said trying to cool off the planet by creating a kind of artificial sun block would delay the recovery of the Antarctic ozone hole by 30 to 70 years and create a new loss of Earth’s protective ozone layer over the Arctic.

“What our study shows is if you actually put a lot of sulfur into the atmosphere we get a larger ozone depletion than we had before,” said Simone Tilmes of the National Center for Atmospheric Research in Boulder, Colorado, whose research appears in the journal Science.

New Zealand’s Largest Glacier Rapidly Shrinking

NEW ZEALAND

Largest glacier shrinking quickly

WELLINGTON — New Zealand’s biggest glacier is melting at its fastest pace in recent history, Massey University glacier expert Martin Brook said Thursday. The Tasman Glacier on South Island was 18 miles long in 1990, with virtually no lake at its front edge.
New measurements last week showed the glacier was 14 miles long, Brook said.
Meanwhile, a lake that has formed next to the glacier is now 4.4 miles long, 1.2 miles wide and 800 feet deep, he said.
