Climate Council (or Should that be Climate CON-cil?) - 5 Myths.

by Geoff Brown and Anthony Cox

Cartoons by Josh

The Climate Council, (or Should that be Climate CON-cil?) true to their nature have published a fairy tale called Mythbusting Guide for Christmas BBQs.  There is hardly a sentence in their release which is true.

Let’s look at their five "myths." (Should that be misses....Do they have a lisp?)

1: The Climate Isn't Getting Warmer, we still have cold weather:

The Climate Council erroneously writes:: 
The Earth has warmed strongly over the past half-century and continues to warm. 
Did the earth warm over the last half century? Well, yes and no. Let's define the last half century, say 1963 to 2013. And the record shows that 1963 to around 1975 was a cooling period followed by 1975-98 warming followed by a cooling period from 1998 to 2013.

Using the (UN)Skeptical Science trend calculator and the RSS satellite data there is a warming trend from 1979 to 1997 of 0.071ºC per decade and from 1998 to 2013 a cooling trend of 0.052ºC per decade.

At the beginning of this 50 years period, Scientists were worried that Antarctic ice would cause a new ice age (Link – Real  Science)

So 1963 to 1975 Cooling; 1998 to 2013 Cooling; 1975 to 1997 warming: 25 years cooling and only  22 years warming.  Therefore the Climate Council’s 
The Earth has warmed strongly over the past half-century and continues to warm.
is totally busted.

Then they continue with their lies:
The Greenland and Antarctic Ice Sheets are losing mass
Arctic sea ice has continued to decrease  
They must know that these are lies.


Arctic and Antarctic

And these prevaricators were paid propagandists for the Rudd/Gillard/Rudd government? They should hand the money back!

2: Climate Change isn't caused by humans, it has always happened. 

Well, that's both true and not-true. Climate change HAS always happened. Man has contributed, for example, by the Urban Heat Island effect.  However, the human contribution is insignificant.

The mendacious Climate Council write:
Scientists are more certain than ever that the warming of climate since 1950 has been caused primarily by human activities. 
Are the Climate Council deniers?  Are they just thumping the table? (link)

3: It's only a few degrees of warming, it can't be that bad.

Although the Climate Council try to scare us re warming; In fact, warm is better than cold.  
In a review article published in the Southern Medical Journal, Keatinge and Donaldson (2004) of Queen Mary's School of Medicine and Dentistry at the University of London begin the main body of their text with a clear declaration of the relative dangers of heat and cold when it comes to human mortality: "cold-related deaths are far more numerous than heat-related deaths in the United States, Europe, and almost all countries outside the tropics, and almost all of them are due to common illnesses that are increased by cold." (Link)

4: We’ve always had extreme weather,  it’s not influenced by (man-made) climate change.

The Climate Council states that: 
All extreme weather events are now being influenced by climate change 
Bjørn Lomborg, an adjunct professor at the Copenhagen Business School writes (LINK)
One of the most persistent claims in the climate debate is that global warming leads to more extreme weather. Green groups and even such respectable outlets as Scientific American declare that “extreme weather is a product of climate change.”
 Yet this is not supported by science. “General statements about extremes are almost nowhere to be found in the literaturebut seem to abound in the popular media,” climate scientist Gavin Schmidt of the NASA Goddard Institute for Space Studies said last month. “It’s this popular perception that global warming means all extremes have to increase all the time, even though if anyone thinks about that for 10 seconds they realize that’s nonsense.”
Are extreme weather events getting worse? Well, no!           

Not according to  Kundzewicz et al. (2005) (via Roger Pielke Jr)
Observations to date provide no conclusive and general proof as to how climate change affects flood behaviour.

Not according to Anthony Watts:

Why it seems that severe weather is “getting worse” when the data shows otherwise – a historical perspective

5 The Science is settled

The Climate Council say
The Science is settled. There is no confusion or debate in the scientific community about the reality of climate change 

There is no confusion? This statement is full of confusion. Science and settled is a scientific oxymoron. 

Is there a reality of climate change? Of Course. Climate has always changed since the beginning of time.

By climate change, the Climate Council probably means catastrophic man-made global warming (CAGW). Well,  there definitely is debate in the scientific community about the reality of CAGW.

Climate Change Reconsidered II: Physical Science (CCR-II is an independent, comprehensive, and authoritative report on the current state of climate science. It is the fourth in a series of scholarly reports produced by the Nongovernmental International Panel on Climate Change (NIPCC), an international network of climate scientists sponsored by three nonprofit organizations: Center for the Study of Carbon Dioxide and Global Change, Science and Environmental Policy Project (SEPP), and The Heartland Institute. Whereas the reports of the United Nations' Intergovernmental Panel on Climate Change (IPCC) warn of a dangerous human effect on climate, NIPCC concludes the human effect is likely to be small relative to natural variability, and whatever small warming is likely to occur will produce benefits as well as costs.

Why do the Climate Council continually issue false information

Because, if they reported the truth, they would be out of a job.
