"The recent claims about thousands of new record high temperatures were based on stations whose length-of-record could begin as recently as 1981, thus missing the many heat waves of the 20th century. So, any moderately hot day now will be publicized as setting records for these young stations because they were not operating in the 1930s."

You will be interested in yesterday's Congressional testimony by Dr. John Christy:
Dr. Christy lost a lot of credibility with his support of Roy Spencer's defective analyses of the MSU data. And his invitation to piss on the science was a Republican political initiative clearly indicated by the URL. " republicans.energycommerce.house.gov "

His 'points' seem more a disparagement of the science than a true reading of the state of the research, and are political opinions, not science.

But let us debate anyway.

1. Extreme events, like the recent U.S. drought, will continue to occur, with or without
human causation.

True but misleading. There will always be 'extremes' in any statistical distribution. But that is not the issue. THe issue is the frequency and severity of events compared to 'the normal'. The CHANGE in extreme event frequenqy and magnitude is what is noted.

"These recent U.S.“extremes” were exceeded in previous decades."

Again, misleading and misreading of the science. If the event was a 'once in a millenia' event, it will occur on average about once in 1000 years. But if you find that the distribution has shifted so that this level of extreme event happens once a century, this indicates a change in the location of the 'mean' and this means the whole distribution plot has shifted on the x axis. An indication of a change in the climate.

So his statements are true but misleading. The way of a 'good liar'.

"2. The average warming rate of 38 CMIP5 IPCC models is greater than observations,
suggesting models over-react to CO2. "

Sort of true. THe fact is that warming of the *atmosphere* has lagged the forecasting, and this led to discoveries that the heat storage in the ocean penetrates farther than previously expected. This increases the LAG in the warming (more thermal mass) but by no means invalidates the 'climate sensitivity' figures from scientific studies.

"Policy based on observations will likely be far more effective than if based on speculative models, no matter what the future climate does. "

True but irredemably stupid. The point here is to set policy based on consequences of current action (or inaction) and you cannot set policy based on 'fait accompli'.

"Regarding Arctic sea ice loss, the average model response to CO2 engenders little
confidence because the models’ output fails when applied to Antarctic sea ice conditions."

True, but not a point. It is the fact that arctic ice has FAR exceedded the response we cautiously expected that is the 'warning flag' telling us that we have UNDERESTIMATED the impact of AGW on the polar regions. The models will now be 'refined' to take this into account but science is the process of LEARNING MORE and that will always continue.

On a POLICY front, the fact that models do not tell us EVERYTHING about the consequences of AGW just tells us that policy should be based on the PRECAUTIONARY PRINCIPLE, at least avoiding the extremes that occur in the 'just adapt to it' camp.

3. New discoveries explain part of the warming found in popular surface temperature
datasets which is unrelated to the accumulation of heat due to the extra greenhouse gases,
but related to human development around the stations. This means popular surface
datasets are limited as proxies for greenhouse warming.

The 'heat bubble' around human habitation does not affect AGW data sets since they are weighted by AREA. And studies have shown that even without correcting for the UHI, there is only a small change in the warming results. This is totally undefensible crap based on 'studies' by the denkialist blogs that are easily rebutted by the serious scientists.

"4. Widely publicized consensus reports by “thousands” of scientists rarely represent the
range of scientific opinion that attends our murky field of climate research. "

But does reflect about 98% of the scientists that UNDERSTAND the climate. i.e. the Climate Researchers.

"Funding resources are recommended for “Red Teams” of credentialed investigators, who study
low climate sensitivity and the role of natural variability."

O.k. Natural variability should be an active area of research, but how do you separate out the 'natural variability' when you are pushing the climate around by AGW at the SAME TIME. Science will find it very difficult to separate out the 'natural' from the 'anthropogenic' when the anthropogenic may TRIGGER 'natural changes' that are 'unnatural',i.e would not have occured without the anthropogenic contribution. More research is needed but you CANNOT separate out the 'natural' from AGW.

"Policymakers need to be aware of the full range of scientific views, especially when it appears that one-sided-science is the basis for policies which, for example, lead to increased energy costs for citizens."

A statement to which you can only agree, but based on TWO 'faulty or unproven assumptions'.

A: That shifting away from fossil fuels will 'increase costs'. Fact is that fossil fuel prices are increasing rapidly as we scramble for the 'remaining secondary grade resources' and that at the same time, alternative 'green' energy has REDUCED in cost every year.

B: That the 'full range of scientific views' currently includes a denial of AGW. ALL the major science academies have published statements that confirm that AGW is solid science. The 'scientists' with alternate 'opinions' don't have the science to back them.

"5. Atmospheric CO2 is food for plants which means it is food for people and animals."

Bogus 'demagoguery'. The actual 'food' for plants are minerals from the soil, glucose from cloroplasts and oxygen from the atmopshere. During the night, plants cannot produce 'food' even though the CO2 levels are just as high as during the day, so obviously CO2 is not 'food'. The photosynthetic reaction in the chloroplasts convertes inert CO2 to glucose and oxygen.

"More CO2 generally means more food for all."

Lie. More CO2 will generally produce more woody cellulose matter. THis makes BIGGER plants but the FOOD value actually drops because the closing of stomata to restrict the entry of too much CO2 also reduces transport of water from the roots and therefore limits minerals which are key to producing vitamins, proteins, etc.

"Today, affordable carbon-based energy is a key component for lifting people out of crippling poverty."

Cheap energy is certainly critical to improving standards of living but by no means has the 'fossil fuel age' lifted the global population out of poverty. Nor are fossil fuels the cheapest energy today. Indeed, as supply diminishes and the cost of extraction increases, they are becoming an EXPENSIVE fuel compared to nuclear and green energy. If you want 'cheap energy' we should be exploring setting up Solar Power Satellites, which would produce clean and abundant energy to every nation with no 'externalized cost'. THe externalized cost of fossil fuels are just now being realized and added to their 'internal costs' it indicates that it is high time we moved on.

"So, rising CO2 emissions are one indication of poverty-reduction which gives hope for those now living in a marginal existence without basic needs brought by electrification, transportation and industry."

Bogus propaganda. THere is NO science here. Just a 'ideology of carbon'. We already know his POLITICAL opinions are tied to fossil fuel companies.

"Additionally, modern, carbon-based energy reduces the need for deforestation and alleviates other environmental problems such as water and deadly indoor-air pollution. Until affordable and reliable energy is developed from non-carbon sources, the world will continue to use carbon as the main energy source."

Bogus propaganda. Demagoguery like 'modern' could be more accurately applied to alternative energies such as wind and geothermal. Clean energy without the 'soot and smog' of the past. Deforestation has NO connection to energy. It goes on in high energy use countries and countries that have low energy use. As to indoor pollution, green clean energy would reduce the pollution both indoors AND out. Not sure where he makes this connection anyway. Etc. Etc. pure bullshit, demagoguery and fossil fuel company propaganda. NO science here.

My argument about climate change mitigation and man made catastrophic global warming alarmism comes down to a lack of any experiment for those theories.
Most people know that science has moved on from the age of the 'alchemists', i.e. the last idiots to think that 'experiment' was the whole of science. Well, I will concede that you may be a 'throwback' to alchemy, but basically, I suspect you are just ignorant of science methodology. If anything can be said to be at the core of science, it would be mathematics.

It's unanimous:

Senate votes to shield U.S. airlines from EU's carbon scheme

By Valerie Volcovici
WASHINGTON | Sat Sep 22, 2012 4:27pm EDT
(Reuters)- The Senate unanimously passed a bill on Saturday that would shield U.S. airlines from paying for their carbon emissions on European flights, pressuring the European Union to back down from applying its emissions law to foreign carriers.
The European Commission has been enforcing its law since January to make all airlines take part in its Emissions Trading Scheme to combat global warming, prompting threats of a trade fight.

The Senate approved the bill shortly after midnight, as it scrambled to complete business to recess ahead of the November 6 congressional and presidential elections....

Ooo wonderful. Next they will 'outlaw' pollution.

All this does is bar US airlines from EU airspace. First step in a trade war. Just what the US needs.

I'm still waiting for you to provide evidence that Watts closed his blog "to build up suspense for" whatever it was?

Why not admit that you don't have an inkling as to how many of the 3,135 July temperature records were accurate.
You certainly wouldn't want to admit, or bother to mention that any low temperatures were broken.

The remarkable thing about minimums is that in some states the minimum temperature was above the previous maximum.

The remarkable thing about high records is that these are usually more about extreme local conditions, yet centuries old records were getting broken across the country.

You're not going to persuade people that nothing remarkable happened because they were simply looking at the wrong thermometers.

If you paid attention to the news rather than rubbish that desperate deniers try to con the gullible with, you'd know this and wouldn't make yourself look so ridiculous.

Record high temperatures far outpace record lows across U.S.
November 12, 2009

BOULDER—Spurred by a warming climate, daily record high temperatures occurred twice as often as record lows over the last decade across the continental United States, new research shows. The ratio of record highs to lows is likely to increase dramatically in coming decades if emissions of greenhouse gases continue to climb.

"Climate change is making itself felt in terms of day-to-day weather in the United States," says Gerald Meehl, the lead author and a senior scientist at the National Center for Atmospheric Research (NCAR). "The ways these records are being broken show how our climate is already shifting."

....

An expanding ratio

The study team focused on weather stations that have been operating since 1950. They found that the ratio of record daily high to record daily low temperatures slightly exceeded one to one in the 1950s, dipped below that level in the 1960s and 1970s, and has risen since the 1980s. The results reflect changes in U.S. average temperatures, which rose in the 1950s, stabilized in the 1960s, and then began a warming trend in the late 1970s.

Even in the first nine months of this year, when the United States cooled somewhat after a string of unusually warm years, the ratio of record daily high to record daily low temperatures was more than three to two.

Despite the increasing number of record highs, there will still be occasional periods of record cold, Meehl notes.

The June to July heat wave finally began to ebb on Saturday, but not before breaking thousands of warm temperature records across the country. In many cases, records that had stood since the Dust Bowl era of the 1930s have been equaled or exceeded, and this event is likely to go down in history as one of America's worst early summer heat waves.
