two more bullets for the anthropogenic Global Warming alarmists

Two pieces of  research that the Al Gore pseudo-scientists (a.k.a. climatologists) will want to suppress.

First concerns polar volcanoes:  (lifted straight from Browning Newsletter on Climate: Shifting into Autumn)

Alaska’s Mt. Redoubt and Russia’s Sarychev Peak in 2009, and, during this year, Iceland’s Grímsvötn and Chile’s Puyehue-Cordón Caulle have all erupted.

Another volcano, Mt. Sheveluch on Russia’s Kamchatka Pennisula, may have joined these ranks. The volcano is currently erupting 8.6 km (5.3 miles) high. This is high enough that it is forcing airlines to reroute their circumpolar flights, particularly those to Japan and Northern China. It has been erupting all month and, off and on, all year. The mountain is remote and hard to observe so some of the eruptions may have been high enough to enter the stratosphere. At a minimum, the debris is drifting down wind and raining out over North America.

If eruptions are big enough for their columns to enter the stratosphere, the debris can linger for years. This has multiple effects on the weather including:

o The ash and chemicals block out incoming sunlight, cooling the air.

o Water collects around the aerosols (solid and liquid particles) forming clouds, which also block incoming sunlight.

o When the clouds finally precipitate out, the rains and snows are unusually heavy.

o The cooler air changes air pressure which changes wind patterns.

In the case of volcanoes near the Arctic and Antarctic, this means the changed air pressure weakens the circumpolar winds. These are winds that circle around the poles, trapping most of the frigid air over the Arctic or Antarctic. If the winds are weak, these frozen air masses can escape. We saw this last winter when the Arctic air masses escaped south and buried 48 of the 50 states in snow, brought European Christmas travel to a standstill and inundated Asia.

We are currently seeing this in the Southern Hemisphere. The Chilean government declared an official “catastrophe” after heavy snows that the nation’s Interior minister called a “white earthquake.” The nation’s capital had rare snow and southern regions have as much as 9 feet (2.7 meters). South Africa, which usually receives a dusting about once or twice a year, has been hit with storms that have dumped up to 60 cm (2 feet) in some areas. New Zealand was hit by a freak winter storm with heavy snow and bitterly cold weather two weeks ago, snowing on Wellington for the first time in decades.

This is a warning for the Northern Hemisphere. In summertime, the polar air masses are trapped north. Europe, Asia and North America have been more affected by balmy tropics. As fall evolves, the polar air masses will spread south, bringing a cold wet harvest season, particularly for Europe, China and the US. This will be followed by a frozen winter.

The second from http://opinion.financialpost.com/2011/08/26/lawrence-solomon-science-now-settled/

63 CERN scientists from 17 European and American institutes have done what global warming doomsayers said could never be done — demonstrate that cosmic rays promote the formation of molecules that in Earth’s atmosphere can grow and seed clouds, the cloudier and thus cooler it will be. Because the sun’s magnetic field controls how many cosmic rays reach Earth’s atmosphere (the stronger the sun’s magnetic field, the more it shields Earth from incoming cosmic rays from space), the sun determines the temperature on Earth.

Basically both of these items point up that clouds have a significantly greater effect on Global climate than Greenhouse gases, whether they are produced by ungulates, termites or us nasty fossil fuel burners.

In both cases rain droplets form on dust particles from volcanoes , or ions caused by cosmic rays.

These rain droplets form clouds, which act as a blanket preventing sunlight from reaching the Earth’s surface.

Obviously the clouds also keep us warm at night, which is why cloudy Winter nights are less frosty but the reflection of the Sun’s heat is more significant than the loss of the Earth’s radiated heat.

Despite arguments to the contrary, it supports the observation that the absence of contrails, after 9/11 left the air above America warmer (http://www.celsias.com/article/9-11-contrail-climate-effects-questioned/).
