The conclusion was that volcanoes may have a greater cooling effect than previously recognised.
In fact, even the UN's Intergovernmental Panel on Climate Change acknowledges that pollutant particles reflect sunlight back into space, which has a cooling effect.
Less ice on rivers, lakes and the sea will lead to more evaporation, probably increasing cloud cover at mid-levels, which should have a cooling effect.
Thus, a cooling effect in these times is not necessarily bad and, in the end, this strategy should be more efficient than permanent restrictions or oversight.
It contributed important new understanding on subjects such as the chemistry of the protective ozone layer and the cooling effect volcanoes can exert on the global climate.
Extend this out to the 30% of jobs which require such licenses and you can see that there will be something of a cooling effect on labour mobility.
FORBES: A Use For The Commerce Clause: Increasing US Labour Mobility Through Occupational Licensing
They also conclude that greenhouse warming has partially been offset by the cooling effect of aerosols - tiny particles of dust thrown into the atmosphere that can reflect solar radiation back into space.
As temperatures soared across the US this week we brought you five eco gadgets to beat the summer heat, and we also learned that solar panels have a cooling effect on buildings.
ENGADGET: Inhabitat's Week In Green: solar-powered stadium, bipod flying cars and biofueled flights
Every 20 to 30 years, the much colder water near the bottom of the oceans cycles up to the top, where it has a slight cooling effect on global temperatures until the sun warms that water.
FORBES: To The Horror Of Global Warming Alarmists, Global Cooling Is Here
While ice reflects around 80 percent of the sun's heat, having a cooling effect, blue sea water can absorb up to 95 percent of solar radiation, warming up the sea and accelerating the melting process further.
Many students of climate change argue that, although the artificial release of greenhouse gases such as carbon dioxide works to raise the global temperature, particulate pollution should, by promoting cloud cover and thus reflecting solar energy back into space, have a compensating cooling effect.
Although sulfate particles may have had the short-term effect of cooling temperatures, in the long run, pumping CO2 into the atmosphere spells trouble.
To find out what effect a cooling device might have on athletic performance, Dr Grahn and Dr Heller recruited a colleague who was a recreational weightlifter.
But rates were frozen for the second consecutive month at 4.75% almost a fortnight ago, having climbed from 3.5% in November last year - an indication the MPC was confident the rises were having the desired effect of cooling house prices and curbing high consumer borrowing.
The aggregate effect, globally, is thought to be a cooling, possibly a quite strong one.
The effect of the president's order is to impose a 60-day cooling off period and give negotiators more time to reach an agreement, according to a White House spokesman.
Just such an aerosol effect is believed to have disrupted the Earth's thermal balance during the Laki event, cooling some Northern Hemisphere regions by as much as 1 or more degrees Celsius below the long-term average.
The glaze is applied to a fired stoneware vessel, which is then fired again in a repeated cycle of six stages of heating and cooling where precise temperatures matter a great deal: either over- or under-firing will spoil the effect.
