Somewhere under the Moonbow, down a Maui blowhole, and severe erosion along the West Coast

Good Morning Humboldt County!

Grab a cup of Joe and let’s go. There’s always something different like a moonbow:

Somewhere under the moonbow

Here’s something you don’t see every day — in fact, you can only experience it at night. It’s called a moonbow and if you’re at Yosemite National Park this weekend, you might want to consider staying up late to catch a glimpse.

As the lunar equivalent of rainbows, moonbows are created when moonlight shines on droplets of water. And with its abundant waterfalls and clear, artificial light-free skies, Yosemite is an ideal place to watch for moonbows, especially on July 15 during the next full moon.

Tourists saw Calif. man fall into Maui blow hole

Witnesses who watched a Northern California man get sucked into a Maui blow hole to his apparent death say that the tourist was dancing around and frolicking in the sprays of water moments before a wave knocked him down.

Piganelli, of La Jolla, Calif., told The Associated Press that he watched the man spiral down the blowhole, pop up briefly before disappearing when the next wave hit. The 44-year-old man, identified as David Potts of San Anselmo, Calif., has not been found since Saturday afternoon. (AP Photo/Rocco Piganelli)

Battered West Coast a lesson on warming, study finds

Severe erosion along the West Coast during the winter of 2009-2010 offers a look at, and lessons for, a warming world with rising sea levels, a new study finds.

A natural El Nino cycle that warms the Pacific Ocean produced those severe conditions, but computer models suggest that similar damage could come from sea level rise tied to human-caused greenhouse gases.

"If these trends continue," U.S. government and academic experts wrote in their study, "the combination of large waves and higher water levels, particularly when enhanced by El Ninos, can be expected to be more frequent in the future, resulting in greater risk of coastal erosion, flooding, and cliff failures."

Lead author Patrick Barnard, a coastal geologist with the U.S. Geological Survey, told msnbc.com that the study serves as a platform "to understand the broad coastal impact of conditions we are likely to experience more frequently in the future."

Time to walk on down the road…
