Current Climate Changes Are Normal: It’s Time The Media Got the Story Correct.

Challengers to the Intergovernmental Panel on Climate Change (IPCC) science of global warming and later climate change were rewarded with illogical, personal attacks, not answers. Most, especially the media, never investigated questions challengers asked or considered contradicting facts they presented. Challengers were always questioned about qualifications, funding or political affiliations. Questions never asked of members and supporters of the IPCC.

Challengers were called global warming skeptics even though they acknowledged warming but showed it was not due to CO2. They also pointed out that all scientists must be skeptics. They were called climate change deniers when they knew climate changes and educated anybody who would listen how much and how often. The media never even investigated why the IPCC changed from Global Warming to Climate Change.

Bloomberg Business News cover page headline about the storm Sandy that hit New York says, “It’s Global Warming, Stupid.” This is a candidate for one of the most ill-informed, misleading, headlines. Apparently they, like most of the media, are so blinded by political bias they neglect to check facts. They know the public, especially those with similar political persuasion, don’t understand that;

the world hasn’t warmed since 1997;

the storm, Sandy, that triggered the headline wasn’t unusual in the historic record;
the intensity of the storm was amplified by cold arctic air brought in by the Jet Stream a factor that was ignored because warm is the default bias;

and weather patterns are well within natural climate variability, which is far greater and more rapid than most understand.

Sandy occurred mostly New York State so its history is telling. Only 8000 years ago New York State emerged from under the massive ice sheet that covered two-thirds of North America just 18,000 years ago.

There were similar large ice sheets in Europe and Asia.

Water removed from the oceans to build the glaciers lowered sea level by 140 m. It has risen by that amount since and the rate of rise has leveled.

The graph shows how much temperature changes naturally with a range of 12°C and dramatic swings. These are greater when you understand that a 70 year smoothing average is applied. This equates to using a single temperature for the last 70 years. Which 70 years would the media choose as ‘better’ than today. Think of recent cold winters and consider whether it was better. The world was almost as warm as today for a fraction of the last half million years.

For most of the last 10,000 years the world was warmer than today: a period variously known as the Climatic Optimum, the Hypsithermal and now the Holocene Optimum. It is recorded in the Greenland ice core.

On average it was 3°C warmer than today for most of the 10,000 years. Further tangible evidence of warmth is the existence of a fossilized white spruce photographed and radiocarbon dated at 4949 before present (BP) by Professor Ritchie. (indicated on the ice core chart.).

It is important to note the existence of the Medieval Warm Period (MWP) and the more recent Little Ice Age (LIA) on the right side of the graph. Through the work of Michael Mann and others at the Climatic Research Unit (CRU) of East Anglia and given prominence in the 2001 IPCC Report the MWP was eliminated. Phil Jones, another CRU and IPCC author, determined the up turn in temperatures after the LIA was more and faster than any in the natural record and proof of human CO2 influence. Compare that claim with the remainder of the Greenland and Antarctic ice core records. Compare it with the fluctuations in the modern record from 1750.

None of those temperature records are driven by CO2. In each the temperature increases before the CO2 contradicting the fundamental assumption of the IPCC . The modern record shows a similar pattern with natural and human CO2 production. In the twentieth century temperature increased the most from 1900 to 1950 but human production of CO2 was lower. Production increased dramatically after WW II, but temperatures declined.

They increased from 1980 to 1998 and the IPCC exploited this as proof of global warming. They claimed the 1990s was the warmest decade ever and was the result of increasing CO2 from human activities. Then in 2000 the wheels fell off – CO2 continued to increase but temperatures stopped increasing. Instead of acknowledging their hypothesis was wrong because their predictions were wrong and the evidence didn’t match their claims the IPCC moved the goalposts from global warming to climate change. The biased media were easily duped, asked the wrong questions or no questions at all and attacked those who did. They didn’t consider the historic context or ask what caused the changes because they didn’t know that climate changes all the time and current changes are natural. Would somebody please tell them?
