... nor using local weather instances as an indicator of global temperature means. hehehe Someone wasn't paying attention in science class. lolI guess AnnaG, that some people never learned the folly of using short time series to infer from.
Historic snow event in South America
23 07 2009
By Alexandre Aguiar / MetSul Weather Center
A major and historic winter storm is underway at this Wednesday morning in Argentina. Snow is falling in many parts of the country and in many areas not used to winter precipitation. Local news reports indicate snow already have been observed in the provinces of Mendoza, San Luis, San Juan, Cordoba, La Pampa and Buenos Aires.
In Bahia Blanca, a coastal city in the Southern part of the Buenos Aires, the snow storm is heavy and local authorities describe it as the worst snow event in 50 years. Roads are already blocked by snow and ice in the regional. TN news channel reports some areas of the Sierra de La Ventana could pick up even 3 feet of snow, unimaginable to the region.
Early this Wednesday afternoon, satellite pictures were showing a band of clouds advancing to the North and snow precipitation could no be ruled out in the capital Buenos Aires. In July 9th and 10th 2007 it snowed in the city of Buenos Aires for the first time in 89 years and it could snow again just two years later. Snow was also reported in the capital of Chile Santiago. MetSul Weather Center is not ruling out snow also in Uruguay.

So what is normal? How is that temperature decided? If we average the whole current interglacial period as our "normal" standard, then we are currently well below normal.

Lawrence Solomon: New Ice Age could be coming
Posted: August 24, 2009, 7:01 PM by Lawrence Solomon
Earth could soon be entering a new Ice Age, according to scientists at Oregon State University and other institutions, in a study to b e released this week by Science magazine.
"Sometime around now, scientists say, the Earth should be changing from a long interglacial period that has lasted the past 10,000 years and shifting back towards conditions that will ultimately lead to another ice age - unless some other forces stop or slow it," states a release from Oregon State University.
The Science study refutes claims by some scientists that carbon dioxide was an important factor in ending the last ice Age. It concludes that wobbles in Earth's rotation first led global ice levels "to reach their peak about 26,000 years ago, stabilize for 7,000 years and then begin melting 19,000 years ago, eventually bringing to an end the last ice age.
"The melting was first caused by more solar radiation, not changes in carbon dioxide levels or ocean temperatures, as some scientists have suggested in recent years."

Be It Resolved: the present massive scale of human activity, including burning of huge amounts of hydrocarbons, along with monstrous changes to geography through canals, dams, and mining projects, have zero effect on the world's climate.

It's comfortable if a bit gloomy here in northern BC, at the moment. But it's going to get hot again, according to the weather. Some ice-age.
While the sun sleeps
Indeed, global warming stopped and a cooling is beginning. No climate model has predicted a cooling of the Earth, on the contrary. This means that projections of future climate is unpredictable, writes Henrik Svensmark.
The star which keeps us alive, has over the last few years almost no sunspots, which are the usual signs of the sun’s magnetic activity.
Last week, reported the scientific team behind Sohosatellitten (Solar and Heliospheric Observatory) that the number of sunspot-free days suggest that solar activity is heading towards its lowest level in about 100 years’. Everything indicates that the Sun is moving into a hibernation-like state, and the obvious question is whether it has any significance for us on Earth.
If you ask the International Panel on Climate Change IPCC, representing the current consensus on climate change, so the answer is a reassuring ‘nothing’. But history and recent research suggests that it is probably completely wrong. Let us take a closer look at why.

More oxygen – colder climate
From the University of Copenhagen news release. 9 September 2009
Using a completely new method, researchers have shown that high atmospheric and oceanic oxygen content makes the climate colder. In prehistoric times, the earth experienced two periods of large increases and fluctuations in the oxygen level of the atmosphere and oceans. These fluctuations also lead to an explosion of multicellular organisms in the oceans, which are the predecessors for life as we know it today. The results are now being published in Nature.
Everybody talks about CO2 and other greenhouse gases as causes of global warming and the large climate changes we are currently experiencing. But what about the atmospheric and oceanic oxygen content? Which role does oxygen content play in global warming?
This question has become extremely relevant now that Professor Robert Frei from the Department of Geography and Geology at the University of Copenhagen, in collaboration with colleagues from Departamento de Geologı´a, Facultad de Ciencias in Uruguay, Newcastle University and the University of Southern Denmark, has established that there is a historical correlation between oxygen and temperature fluctuations towards global cooling.

More oxygen – colder climate « Watts Up With That?
Of course there is a relationship. The solubility of a gas in a solution is inversely proportional to the temperature of that solution. If the ocean cools, then the amount of oxygen at saturation increases. If the ocean warms, then the amount of oxygen at saturation decreases. So large climate swings will result in significant changes in ocean chemistry.
Oh and have we dropped below the 1000 year mean average to be considered as cooling or have we lost a little of what we gained and still far above the 1000 year mean?
