Pacific Decadal Oscillation?

Just when Al Gore has done another investment placement around global warming issues we get word of Pacific decadal Oscillation? Say what? The investment vehicle headed by Al Gore has closed a new $683m fund to invest in early-stage environmental companies and has mounted a robust defence of green investing. The Climate Solutions Fund will be one of the biggest in the growing market for investment funds with an environmental slants.

The allegedly global warming is in for about 30 years of cooling according to NASA, one of the leading global warming theory advocates. Who's a person to believe?

Will we need a recount of those for and against global warming, without hanging chads? :-)

NASA has confirmed that a developing natural climate pattern will likely result in much colder temperatures, according to Marc Shepherd, writing in the April 30 American Thinker. He adds that NASA was also quick to point out that such natural phenomena should not confuse the issue of manmade greenhouse gas induced global warming which apparently will be going on behind the scenes while our teeth are chattering from a decade and a half long cold spell.

I'm confused here!

"A cool-water anomaly known as La Niña occupied the tropical Pacific Ocean throughout 2007 and early 2008. In April 2008, scientists at NASA's Jet Propulsion Laboratory announced that while the La Niña was weakening, the Pacific decadal Oscillation - a larger-scale, Slower-cycling ocean pattern - had shifted to its cool phase." Will Al believe this?

Notes Shepherd "This shift in the PDO, which could last for 20 or 30 years, can have significant implications for global climate, affecting Pacific and Atlantic hurricane activity, droughts and flooding around the Pacific basin, the productivity of marine ecosystems and global land temperature patterns."

And the greatest impact here in the states, he adds, will likely be on west Coast residents, particularly growers. Well, that should make for some great white wines, but who likes white? Better buy the reds now! Warns meteorologist Anthony Watts: "Look out California agriculture. The wine industry, fruits and nut growers will be hit with a shorter growing season and more threats of frost, among other things."

Watts cites two recent reports of frost-induced crop devastation - an apple orchard in Paradise and wine grapes in Nevada County. He also offers a brief history of last century's PDO phase shifts, and warns that California's agriculture, which experienced "unprecedented growth" during the past warm phase, may now be in serious trouble as things cool down.

But what about helioseismological increases? :-)

In 1905, PDO switched to a warm phase, in 1946, PDO switched to a cool phase, and in 1977, PDO switched to a warm phase again. Now they tell us! Notes Shepherd "Recently lower global temps, likely caused by the late start of Solar Cycle 24, already have some greenhouse gassers nervous - particularly amid speculation of a possible impending 'little ice age.'

But what about the solar peaks of 2012? Ah, we're just into what's happening here on earth, not what's going on out there in space. But, maybe we'll be forced too. Today has enough trouble for it's own.

Says NASA: "Natural, large-scale climate patterns like the PDO and El Niño-La Niña are superimposed on global warming caused by increasing concentrations of greenhouse gases and landscape changes like deforestation. According to Josh Willis, JPL oceanographer and climate scientist, ‘These natural climate phenomena can sometimes hide global warming caused by human activities. Or they can have the opposite effect of accentuating it.'"

In other words, CO2 is secretly warming the planet. Or maybe not. Maybe it's due to things in the universe since ALL o the planets in our solar system are warming up.
