Deniers pwnd


What a week. Texas burned in the midst of its global-warming-fueled drought, and in Somalia hundreds of people were dying every day of hunger and thirst, in a region driven to the edge of mass catastrophe by a combination of critical drought, high food prices, and political and social chaos.

Spencer and Braswell continued to take a beating, as Dessler (2011) exploded their toy models with actual data, and showed their sloppy methods implied ocean warming causing ocean warming. Skeptics were duely chastised and promised to curb their overreaching claims based on unphysical models ignoring actual physical evidence (kidding about that one.)

Rick Perry took the Galileo Effect mainstream in last night's Republican debate, but not before we explored how totally nonsensical such an invocation is:



Perry's bumbling invocation of this minor myth was part of a shrill and unimpressive showing in which he called Social Security a "massive lie" and a "Ponzi scheme." In this the new face of climate denial? Let's hope so.

Meanwhile, two other denier candidates, Michelle Bachmann and Ron Paul, went on record opposing mandatory vaccinations for schoolchildren. As we've noted before, the different strains of anti-science denial have significant overlap.

The Yale Project on Climate Change Communications had some good news for those of us who spend too much time in the blogosphere: outside the Tea Party, every group of voters -- including Republicans, albeit more narrowly than Democrats or independents -- favors a binding international treaty to cut CO2 emissions. The Tea Party -- only 12% of the population -- are the only ones who think global warming isn't happening.

How little influence do "loud and proud" deniers wield? More than three-quarters of the public has never heard of "climategate." Half the Tea Party members have never heard of it.

Sea ice volume is at record lows, area and extent will go down to the wire vs mighty 2007. The sea ice volume chart really tells the tale:



After the plunge in 2007, we see a slight increase in the seasonal low the following year, as you would expect, based on the principle of regression towards the mean. But with that one exception, every year for the past ten years has seen the ice hit a new record low. It's awfully close to the continual steady change that deniers always demand as proof of outside influence -- although since that kind of steady change is rarely seen in large, complex systems, it really implies such a rapid change that the natural variation of the system has been completely overwhelmed.

Climate scientists continue their observations of the natural world, while also, gradually, improving how they communicate scientific findings:



And the public is willing to listen: scientists are still be far the most trusted source of information about climate change -- even among deniers!

All and all, if you deny the physical reality of global warming and view mitigation of these rapid, irreversible changes as an eco-Marxist conspiracy to install the collectivist New World Order, you might want to take a long weekend, start fresh on Monday. Because this week things are just not going your way.

Idiot comment of the day



Words fail me:

NOAA’s Data shows that ice accumulates rapidly during warm times and slowly during cold times. It snows more in Antarctic when the oceans are warm. The NOAA Ice Core data shows that. It snows more in Greenland when the oceans are warm. The NOAA Ice Core data shows that. It snows more in Europe and Asia and North America when the Warm Ocean Currents melt Arctic Sea Ice. For Example, this past Winter and other Winters during the past Decade.

When Oceans are cold, it snows less and ice retreats. When Oceans are warm, it snows more and ice advances. This powerful negative feedback is the Thermostat of Earth. Pay attention to the agreement between Low Arctic Sea Ice Events and severe winters around the Northern Latitudes. Look up these events during the past Decade.

Consensus Climate Scientists leave this powerful negative Albedo feedback effect out of their Theory and Models.

Warm Oceans melt Arctic Sea Ice and cause it to snow more. That is when the oceans drop.

Does anyone look at the Actual Data? Most of the Replies are not about the data. Forecasts are just forecasts, but data is data.


Hot temperatures cause ice to advance -- or should that be hot temperatures Cause the ice to Advance. Yep, it'll be a new ice age soon, the way things are going. Just look at the data:



No, not that data! The data from Greenland!



No, not that data from Greenland! What about Antarctica?



You're better off sticking with the critique the original Alexander Pope gave of people like Herman:

Of all the causes which conspire to blind
Man's erring judgment, and misguide the mind;
What the weak head with strongest bias rules, —
Is pride, the never-failing vice of fools.

Sea ice extent -- headed for a record low?



Neven's sharp eyes direct us to a high-pressure system over the Arctic that has shifted the Arctic melt into overdrive:



And as the graph above shows, the result is a race for the record:

2011 decided to forge ahead, leaving 2010 in the dust and even increasing the lead over 2007. This is quite amazing as 2007 had a stunning run of century breaks in this first part of July. I guess I don't have to explain that this means 2011 is currently leading in the race. 2010 is finished for the rest of the month and will fall back quickly. The same goes for 2006, albeit to a lesser extent. 2009 will start to put up a fight towards the end of the month. But right now it's between 2011 and mighty 2007.

PIOMAS plunges to a new record low



The linear decline in Arctic ice volume is looking less and less plausible. It seems likely that what we are facing is an exponential decline in ice volume and, ultimately, in sea ice extent.

Warming in the Arctic will continue to accelerate, as the open water absorbs far more of the incident sunlight than the highly reflective surface of the ice. While this ice is not going to raise the sea level, since it is already floating over the ocean, the loss of this ice and the attendant local warming are accelerating losses from the northern portion of the Greenland ice sheet, which represents 7 meters of sea level rise in total, enough to put the homes of 700 million people under water.



Greenland's melting season last year shattered records. What will 2011 bring?
