---->"The biggest mystery in climate science today may have begun, unbeknownst to anybody at the time, with a subtle weakening of the tropical trade winds blowing across the Pacific Ocean in late 1997...Average global temperatures hit a record high in 1998 — and then the warming stalled....But the pause has persisted, sparking a minor crisis of confidence in the field. Although there have been jumps and dips, average atmospheric temperatures have risen little since 1998, in seeming defiance of projections of climate models and the ever-increasing emissions of greenhouse gases."
The above plots of temperature datasets from different climate agencies/organizations clearly indicate that the feared accelerating and runaway warming predicted did not happen, ever. And, for each dataset, the December 2013 temperature anomaly was below the December 1997 anomaly - basically, one could say the globe has cooled slightly over the past 16 years.
The chart also clearly indicates that billions upon billions of human CO2 emissions have had little, if any, impact on global warming.
This empirical evidence strongly counters any claim that changes in human CO2 emissions, up or down, can be viewed as a "control knob" or "thermostat" for Earth's temperature and climate.
Those stubborn facts about global warming and climate change are not forgiving, nor kind to those who continue to deny the indisputable.
