Warming affects trees, streams in West

Climate change researchers are hesitant to ascribe a single cause for the warming, but they agree it's happening.
"By and large, there is a very detectable warming in this region," said Martin Hoerling, a meteorologist at the NOAA-funded Earth System Research Laboratory in Boulder, Colo. His own research suggests the West could heat up a lot more, possibly by 5 degrees by the midpoint of the century, depending on the level of greenhouse-gas emissions.
The report, "Hotter and Drier: The West's Changed Climate," crunched numbers kept by NOAA's Western Regional Climate Center in Reno, Nev.
"That sounds about right," the center's acting director, Kelly T. Redmond, said.
"It's been warming in this region for the past 35 years, after a cool period in the 1970s. We've been decidedly above average. You could put an exclamation on it," he said.
Redmond has made calculations similar to the report's 2.2-degree rise, which has meant fewer subzero nights to control the population of mountain pine beetles devastating Colorado's lodgepole pines.
At first, he said, "I didn't know whether to trust these numbers or not." They came from a network of about 2,000 thermometers across the West — from airports to weather hobbyists' backyards — recording lows and highs since the late 1800s.
But other recent patterns — earlier snowmelt in spring, earlier lilac and honeysuckle blooms — convinced Redmond the recordings were accurate.
"In 100 years, this is the largest change we've seen, so it catches your attention," he said. "We can't definitely attribute it to human causes, but my suspicion is at least part of it is due to climate change."
The West also is in the grip of a decade-long drought, which tends to raise temperatures, said Hoerling, who likewise is hesitant to attribute the warming of the West solely on carbon emissions. He believes cyclical changes in sea-surface temperatures also are to blame.
The consequences, though, are plain to see. In Yellowstone National Park, aerial photographs show vast orange-needled forests of whitebark pine that were green just three years ago. Yellowstone grizzly bears depend heavily on the fatty seeds of the whitebark pine for food. Colorado's signature aspen stands also are drying up, leaving them vulnerable to fungus.
The Rocky Mountain snowpacks that melt earlier in spring leave less water for summer irrigation and heat up trout streams. Glaciers, which provide consistent stream flows during summer, are melting. The glaciers at Montana's Glacier National Park could melt entirely by 2022, U.S. Geological Survey researchers have calculated.
Montana, Idaho and Wyoming had their hottest Julys on record last summer, while Phoenix had 47 days of 109 degrees or hotter, according to the National Weather Service.
Powell and Mead reservoirs, meanwhile, are half-empty. The reservoirs collect water from the Colorado River, supplying much of the booming Southwest. If they keep drying up, it could shred the Colorado River Compact of 1922, an agreement that allocates fixed amounts of water among seven states.
The upper basin states have the water, but lower basin states including California have senior water rights — a crisis in the making, said Bradley H. Udall, director of the Western Water Assessment Cooperative at the University of Colorado.

'Every day is Mother's Day'

So say students of the UAE, who nonetheless celebrated the day on March 21. They take time out to tell Fatma Salem what a mother means to them.
Motherhood is the greatest blessing on earth. Motherhood is a symbol of kindness, forgiveness and unconditional love. A mother's touch is the first human touch in a child's life. A mother's heart is filled with untiring love for her children. She lives and dies for them and she's the source of love and protection.
Mother's Day is celebrated worldwide to honour all mothers and express gratitude for the hardships they bear in bringing up a child. It is for the unconditional love and care they give their children, long after the child has become an adult and has become old enough to look after himself. Although various countries celebrate the day on various dates, in the UAE it falls on March 21.
This year Notes took the opportunity to give students a chance to express their love for their mothers and to tell us how they define the unique qualities of a mother.

Nice Poem about me !!

Until we meet My nights will be a little colder My days a little shorter My heart will beat a little less rapidUntil we meetI know that my arms will be empty My mind hurting from the constant thought of youMinutes will seem to be hoursHours will seem to be monthsWhile months will seem like eternityUntil we meet The stars in the sky will not affect me with its gleaming sparkles of life
