Nothing interesting will happen in 2012. At least, nothing on the order that a lot of you are thinking.

man, this presenter guy is such an annoying ass. He basically rubbishes Kaku after the interview. Does he realize that Kaku has more cleverness and brain power in his little finger than he does in his whole pathetic body?
Id love Kaku to be right just to **** this guy off.
UV can vary up to 10% and effects the ozone and stratosphere: “UV variability between 200 and 400 nm is almost a factor of 10 larger than was estimated from earlier satellite data.” www.lowell.edu...
The Spectral Irradiance Monitor (SIM) on-board the Solar Radiation and Climate Experiment (SORCE) satellite provides the first multi-year continuous measurements of solar spectral irradiance (SSI) variability from 200–2400 nm, accounting for about 97% of the total solar irradiance (TSI)... the SSI values for wavelengths with a brightness temperature greater than 5770 K show a brightening with decreasing solar activity, whereas those with lower brightness temperatures show a dimming. These results demonstrate that different parts of the solar atmosphere contribute differently to the TSI with the behavior in the deep photospheric layers giving an opposing and nearly compensating trend to that in the upper photospheric and lower chromospheric layers. These findings need to be incorporated into Earth-climate assessments since the solar forcing induced by these differential trends are inherently different from the relatively flat spectral contributions employed in the IPCC assessments. adsabs.harvard.edu...
THE SOLAR WOLF-GLEISSBERG CYCLE AND ITS INFLUENCE ON THE EARTH: Shahinaz M. Yousef , Astronomy &Meteorology Dept. -Cairo University
“The only continuous solar observations that extend over the important climatic time scale of decades to centuries are those of sunspots, yielding a measure of magnetic activity. There are evidences for the modulation of the amplitude of the 11 year solar cycle in a period of about 80 years known as Wolf-Gleissberg cycle. The Cycle seems to be fairly clear in the sunspot record and in its proxy measurements by cosmogenic isotopes. The cycle appears to show up in many meteorological parameters, suggesting that there may be an important sun/climate connection over long periods of time(Hoyt and Schatten 1997).... “A growing mass of evidence suggests that transient events on the sun affect our weather and long term variations of the sun’s energy output affect our climate. virtualacademia.com...
“The Sun is a powerful and highly variable source of ultraviolet and X radiation, which has major effects on our environment.” Author: David H. Hathaway spacescience.spaceref.com...
“While total solar irradiance changes by 0.1 percent, the change in the intensity of ultraviolet light varies by much larger amounts, scientists have discovered. Research shows such variations in the Sun's emissions can affect the ozone layer and the way energy moves both vertically and horizontally through the atmosphere.” www.nasa.gov...
“This is the quietest Sun we’ve seen in almost a century,” says NASA solar scientist David Hathaway. But this is not just a scientific curiosity. It could affect everyone on Earth and force what for many is the unthinkable: a reappraisal of the science behind recent global warming.”

The Pacific Decadal Oscillation (PDO) is a temperature pattern in the Pacific Ocean that spends roughly 20-30 years in the cool phase or the warm phase. In 1905, PDO switched to a warm phase. In 1946, PDO switched to a cool phase. In 1977, PDO switched to a warm phase. In 1998, PDO showed a few cool years. Note that the cool phases seem to coincide with the periods of cooling (1946-1977) and the warm phases seem to coincide with periods of warming (1905-1946, 1977-1998).

Abrupt and sudden climatic transitions and fluctuations: a review: A number of persistent oscillations exist, particularly one about 1500 years, but their amplitudes vary considerably between time periods. The Holocene appears to be no more climatically benign than the similar period in the Eemian. The importance of the North Atlantic thermohaline circulation for generating abrupt climatic changes in Europe, particularly in association with sudden pulses of fresh water, is illustrated. The concept of antiphase temperature changes between the North and South Atlantic is discussed. Externally generated abrupt climatic deteriorations owing to explosive volcanic eruptions and variations in solar irradiance are also discussed.

“The average pressure of the solar wind has dropped more than 20% since the mid-1990s … the speed of the million mph solar wind hasn't decreased much—only 3%. The change in pressure comes mainly from reductions in temperature and density. The solar wind is 13% cooler and 20% less dense. The solar wind isn't inflating the heliosphere as much as it used to … That means less shielding against cosmic rays. Ulysses also finds that the sun's underlying magnetic field has weakened by more than 30% since the mid-1990s”.....The magnetic pole in Northern Canada has been weakening as it shifts across the Arctic to Siberia.....The overall intensity of the magnetic field has decreased.
“Measurements have been made of the Earth's magnetic field more or less continuously since about 1840. If we look at the trend in the strength of the magnetic field over this time (for example the so-called 'dipole moment' shown in the graph below) we can see a downward trend. ... We also know from studies of the magnetisation of minerals in ancient clay pots that the Earth's magnetic field was approximately twice as strong in Roman times as it is now.”
The Earth’s magnetic field “acts as a shield against the bombardment of particles continuously streaming from the sun. Because the solar particles (ions and electrons) are electrically charged, they feel magnetic forces and most are deflected by our planet's magnetic field. However, our magnetic field is a leaky shield and the number of particles breaching this shield depends on the orientation of the sun’s magnetic field. … Twenty times more solar particles cross the Earth’s leaky magnetic shield when the sun’s magnetic field is aligned with that of the Earth compared to when the two magnetic fields are oppositely directed” www.appinsys.com...
