Based on real science and actual, you know, data it seems we are heading in to another cold spell. Via Pajamas Media:
In a cosmically ironic twist of fate and timing, nature may be set to empirically freeze any and all anthropogenic global warming talk: a blast of Arctic cold may encase the earth in an icy grip not seen for 200 years.
This is not alarmist fantasy or 2012 babble — several natural forces that are known to cause cooling are awakening simultaneously, raising speculation of a “perfect storm” of downward pressures on global temperature. These forces let loose one at a time can cause the Earth to cool and can bring about harsh winter conditions. If they all break free at once, the effects could be felt not just in the coming winter, but year-round, and for several years to come.
First up, La Nina:
Since autumn of 2009, we have been under the influence of a moderately strong El Nino. El Nino is a warming of the water in the Pacific Ocean along the equator from South America to the international dateline. El Nino’s warm water adds vast amounts of heat and humidity to the atmosphere. The result is a warmer Earth and greatly altered weather patterns around the world. The current El Nino is predicted to fade out this summer, and frequently after an El Nino we see the development of La Nina, the colder sister of El Nino. La Nina’s cooler waters along the equatorial Pacific act to cool the Earth’s temperature.
And about that Solar Minimum:
We have just exited the longest and deepest solar minimum in nearly 100 years. During this minimum, the Sun had the greatest number of spotless days (days where there were no sunspots on the face of the sun) since the early 1800s. The solar cycle is usually about 11 years from minimum to minimum — this past cycle 23 lasted 12.7 years. The long length of a solar cycle has been shown to have significant short term climate significance. Australian solar researcher Dr. David Archibald has shown that for every one year increase in the solar cycle length, there is a half-degree Celsius drop in the global temperature in the next cycle.
Using that relationship, we could expect a global temperature drop of one degree Fahrenheit by 2020. That alone would wipe out all of the warming of the last 150 years.
Volcano’s… Oh my:
Magnus Tomi Gudmundson is a geophysicist at the University of Iceland, and an expert on volcanic ice eruptions:
There is an increasing likelihood we’ll see a Katla eruption in the coming months or a year or two, but there’s no way that’s certain. …
From records we know that every time Eyjafjallajokull has erupted, Katla has also erupted.
The reason this is ominously significant is that these giant eruptions can change the weather on a planetary scale for years. Mount Laki, another large volcano in Iceland, has a history of producing climate changing eruptions. In the early summer of 1783, Laki erupted, releasing vast rivers of lava. The explosive volcano also ejected a massive amount of volcanic ash and sulfur dioxide into the air — the eruption was so violent that the ash and sulfur dioxide were injected into the stratosphere, some 8 miles up. This cloud was then swept around the world by the stratospheric winds. The result was a significant decrease in the amount of sunlight reaching the Earth’s surface for several years.
That reduction in sunlight brought about bitter cold weather across the northern hemisphere. The winter of 1784 was the coldest ever seen in New England and in Europe. New Jersey was buried under feet of snow. The Mississippi River froze all the way down to New Orleans! Ice was reported in the Gulf of Mexico. Historical records show that similar conditions existed during the following winter.
This convergence of events that have proven in the past to drive down temperatures (and notice that none of these are man made events) should put a damper on all the man made ‘global warming’ hysteria.
