Those characteristics can include a brief dip in air pressure, a change in wind direction, a change in wind speed, a rise in air temperature or a dip in ultraviolet light reaching the rover.
ENGADGET: Curiosity rover finds radiation levels on Mars are safe for humans
Stabilizing greenhouse gas concentrations at 550 ppm -- which would invoke a rise in temperature of about three degrees Celsius -- would require energy emissions to rise no higher than 33 gigatons and would need to fall in the longer term.
Water, however, can absorb 4, 000 times as much heat as air, for a given rise in temperature.
IPCC's worst-case scenario, which is about a 7 degree Fahrenheit rise in temperature, shows a global sea level gain of 10 to 23 inches.
Now we know what we get purely from having the CO2 in the atmosphere, something like a 0.7 oF rise in temperature.
The team suggests it is worth investigating whether the long-term AMO cycles, which are thought to last 65-70 years, may play a part in the temperature rise, fall and rise again seen during the 20th Century.
Many legal policy experts, including the Washington Legal Foundation, have long insisted that the debate over the effects of carbon emissions on the rise in global temperature is strictly a political question that should not be decided in the courts.
But the report warned that just a one-degree centigrade rise in average temperature would reduce this to 500 viable slopes, and that this was likely to happen between 2020-2025.
As it currently stands, the UN Framework Convention on Climate Change has set a target of limiting the rise in global mean temperature to 2C (3.6F) above pre-industrial levels.
This ocean acidification theory is very convenient for global warming alarmists because it allows them to claim a major global warming-related crisis even when global temperatures fail to rapidly rise or rise in a manner that does not produce temperature-related crises.
FORBES: Another Global Warming Crisis Canceled For Lack Of Evidence
Research has shown that the body's temperature tends to rise by a few degrees in the afternoon, warming the muscles and connective tissues and resulting in a slight improvement in your performance capabilities.
Many low-lying nations have used the UN conference, which is currently under way in Doha, to call for a threshold temperature rise less than 2C, arguing that even a 2C rise will jeopardise their future.
His book addresses the argument in cost-benefit terms, and concludes that spending 1-2% of global output to avoid a significant temperature rise is a bargain worth taking a similar conclusion to that in his original 2006 study.
