Mojib Latif predicts that in the next few years a natural cooling trend will dominate because of cyclical changes to ocean currents and temperatures in the North Atlantic, a feature known as the North Atlantic Oscillation (NAO). He told 1,500 climate scientists in Geneve recently: we could be about to enter one or even two decades during which temperatures cool. Read more here.

Marine Cloud Whitening: Best Solution to AGW?
WASHINGTON, DC – After deliberations into the best responses to global warming, an Expert Panel of five top economists including three Nobel Laureates concluded that greater resources should be spent on research into climate engineering and green energy.
The Expert Panel’s findings highlight the problems with the current political focus on carbon taxes, and underscore the vast promise shown by alternative responses to global warming.
The Expert Panel scrutinized 21 ground-breaking research papers by top climate economists that analyzed the costs and benefits of different responses to global warming, ranging from a focus on black carbon mitigation to climate engineering and varying levels of carbon taxes. Based on an analysis of the new research, they created a prioritized list (overleaf) that outlines the best and worst ways to respond to climate change.
The Expert Panel concluded that the most effective use of resources would be to invest immediately in researching marine cloud whitening technology (where boats spray seawater droplets into clouds above the sea to make them reflect more sunlight back into space, reducing warming).

Record Warm Sea Surface Temperatures
SCIENTISTS at the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center (CPC) recently announced that the average global sea surface temperatures in July was 62.6 degrees F making it hotter than the previous record of 1998 and the hottest since record-keeping began in 1880.
The record average is from satellite based measurements and was initially disputed by some sceptics including climate scientists Roy Spencer, University of Alabama, Huntsville. Dr Spencer initially attributed the error to a data processing blunder at NOAA, but has since conceded the blunder in the calculations was his. [Read more…] about Record Warm Sea Surface Temperatures
Sunspots Just Part of The Story: Fred Singer
CLIMATE modelers seem puzzled that small fluctuations in total solar irradiance (TSI) appear to have large influence on the climate.
They feel it necessary to take recourse to complicated mechanisms.
For example, Gerald Meehl of the US-National Center for Atmospheric Research (NCAR) and his team have been able to calculate how the extremely small variations in TSI bring about a comparatively significant change in the system “Atmosphere-Ocean”. [1]
They try to explain how ‘sunspot frequency’ has an unexpectedly strong influence on cloud formation and precipitation.
One suggested mechanism is a solar-UV enhancement of stratospheric ozone, leading to circulation changes in the troposphere, a possibility explored earlier by British researcher Joanna Haigh. Another complicated mechanism suggested is increased heating and evaporation from cloud-free regions of the ocean, with the additional moisture transported into the equatorial zone, followed by some kind of positive feedback.
But the answer may really be very simple. [Read more…] about Sunspots Just Part of The Story: Fred Singer
Global Cooling has Begun: Bob Foster
BIG things are happening Sun-wise. The longer Solar Cycle 24 is delayed, the weaker should it be. Thus, it is more likely day by day – while Cycle 24 remains in deferral – that we are entering the next Little Ice Age cold period (Landscheidt Minimum1).
In 2004, NASA predicted an extra-powerful Cycle 24 starting in 2006, far stronger than modest Cycle 23 – thus supplementing IPCC’s projected people-driven warming. As you might expect, there are very few people outside the ‘mainstream’ consensus policed by Royal Society, IPCC, NASA – and propagated by the great journals Science and Nature – with the expertise to challenge NASA on this esoteric topic. But happily, there are some.
The collective angular momentum of the giant outer planets drives the Sun’s highly-irregular orbit about the centre-of-mass of the solar system (as Newton knew); and the timing (albeit, not yet the magnitude) of consequential solar variability can therefore be predicted. By “variability” I don’t mean in total solar irradiance; because TSI varies only by fractions of a percent. I am referring to the outflow of magnetised plasma from the Sun – which can vary by orders of magnitude at timings from quotidian to millennial.

SPENCER WRONG NOAA Blunder Explains Claims of Warming Oceans?
SCIENTISTS at the National Oceanic and Atmospheric Administration (NOAA) Climate Prediction Center (CPC) appear to have made a blunder with a data adjustment and splice resulting in sea surface temperatures being warmer than they would otherwise be by about 0.175 degrees C over the last two decades.
Roy Spencer, from the University of Alabama, discovered the error just a few days ago which according to meteorologist Anthony Watts, accounts for 24% of the 0.74 deg C global warming claimed for 1905-2005.

UPDATE: THE ERROR WAS ROY SPENCERS
To make a long story short, because the orbit boost caused the TMI to be able to “see” to slightly higher latitudes, the way in which individual latitude bands are handled has a significant impact on the resulting temperature anomalies that are computed over time.
