Quite often you will here Nova comment about the “missing hotspot” as if this were evidence against global warming. It’s not. For intricate details of why, please see previous explanations (1, 2, 3, 4, 5, 6, 7, 8). For a simple summary … (more…)

Nova once again cherry picks data in order to try and fool her readers into thinking global warming is not a threat. This time she and Steve Woodman pick one year, 2011, and one country, Australia and tries to convince you that global warming isn’t happening.
Their error is to ignore the rest of the planet, and to think one year, especially one dominated by the effects of La Nina conditions, represents global climate.
Rather than rely on peer-reviewed science to work out whether the Pacific Decadal Oscillation (PDO) is driving long term climate Nova reposts the workings of “some guy on the internet” who can match observed temperatures using a simple formula.
To demonstrate her incompetence, she labels this work as “heavy stuff, but I know some people will enjoy the challenge of testing Frank’s ideas”.
Nova fails to notice the glaring mistake in Franks first graph. I’m not surprised.
Children understand that even though we have day followed by night etc., this is NOT the same as having permanent day or permanent night. A short term and large fluctuation in the amount of sunlight reaching the planet does NOT mean we could live in conditions that were permanently dark or permanently light. This analogy is the fundamental flaw behind Nova’s latest post on Ocean Acidification.
According to Joanne Nova, news about local hot weather is NOT allowed.
Sky news reported that Adelaide’s 1st Jan 2012 was the hottest since 1900.
Blackouts and fires have marked South Australia’s first heatwave of the summer with Adelaide sweltering through its hottest New Year for more than a century.
Nova’s first handbook contains one of the dumbest arguments I have ever seen (and let’s face it, she says some pretty stupid things). Against the AGW position that the current climate change is rapid, Nova claims …
Last century, temperatures rose about 0.7 degrees (and most of that gain has been lost in the past 12 months). But around 1700, there was a 2.2° C rise in just 36 years. (As measured by the Central England Temperature record, one of the only reliable records of the era.)
Aside from the questionable accuracy of thermometer measurements made 300 years ago, how do we let Nova know that the temperature in Central England does NOT represent that of the GLOBAL average?
In Nova’s handbook, she tells her readers that CO2 is plant food. Such a simplistic view of plant growth has been answered so many times during “skeptical” debate that I can only infer Nova is purposely trying to mislead her readers by reusing this old debunked argument once more.
As usual, Nova cherry picks out one small section of science and ignores everything else.
