MET office are frauds

The MET lying to people
1. “… [F]or Mr. Rose to suggest that the latest global temperatures available show no warming in the last 15 years is entirely misleading.”

2. “What is absolutely clear is that we have continued to see a trend of warming …”.

3. “The linear trend from August 1997 (in the middle of an exceptionally strong El Niño) to August 2012 (coming at the tail end of a double-dip La Niña) is about 0.03 C°/decade …”.

4. “Each of the top ten warmest years have occurred in the last decade.”

5. “The models exhibit large variations in the rate of warming … so … such a period [15 years without warming] is not unexpected. It is not uncommon in the simulations for these periods to last up to 15 years, but longer periods are unlikely.”

Each of the assertions enumerated above was calculated to deceive. Each assertion is a lie. It is a lie told for financial advantage. M’lud, let me take each assertion in turn and briefly outline the evidence.

The METS BS exposed
1. The assertion that Mr Rose was “entirely misleading” to say there had been no global warming for 15 years is not just entirely misleading: it is entirely false. The least-squares linear-regression trend on the global temperature data is statistically indistinguishable from zero for 18 years (HadCRUt4), or 19 years (HadCRUt3), or even 23 years (RSS).

2. What is absolutely clear is that the assertion that “it is absolutely clear that we have continued to see a trend of warming” is absolutely, clearly false. The assertion is timescale-dependent. The Met Office justified it by noting that each of the last n decades was warmer than the decade that preceded it. A simple heuristic will demonstrate the dishonesty of this argument. Take a two-decade period. In each of years 1-2, the world warms by 0.05 Cº. In each of years 3-20, the world does not warm at all. Sure, the second decade will be warmer than the first. But global warming will still have stopped for 18 years. By making comparisons on timescales longer than the 18 years without warming, what we are seeing is long-past warming, not a continuing “trend of warming”.

3. In August 1997 global temperatures were not “in the middle of an exceptionally strong El Niño”: they were in transition, about halfway between La Niña (cooler than normal) and El Niño (warmer than normal) conditions. Likewise, temperatures in August 2012 were not “at the tail-end of a double-dip La Niña”: they were plainly again in transition between the La Niña of 2011/12 and the El Niño due in a year or two.

4. The Met Office’s assertion that each of the past ten years has been in the top ten is dataset-dependent. On most datasets, 1998 was the warmest year on the global instrumental record (which only began 160-odd years ago). Therefore, on these datasets, it cannot have been possible for each of the last ten years to be among the warmest on record.

5. Finally, the Met Office shoots itself in the foot by implicitly admitting that there has been a 15-year period without warming, saying that such a period is “not unexpected”. Yet that period was not “expected” by any of the dozens of lavishly-funded computer models that have been enriching their operators – including the Met Office, whose new computer cost gazillions and has the carbon footprint of a small town every time it is switched on. The NOAA’s State of the Climate report in 2008 said this: “Near-zero and even negative trends are common for intervals of a decade or less in the simulations, due to the model’s internal climate variability. The simulations rule out (at the 95% level) zero trends for intervals of 15 years or more, suggesting that an observed absence of warming of this duration is needed to create a discrepancy with the expected present-day warming rate.”

Australia – was hot and is hot. So what? This is not an unusual heat-wave

The media are in overdrive, making out that “the extreme heat is the new normal” in Australia. The Great Australian Heatwave of January 2013 didn’t push the mercury above 50C at any weather station in Australia, yet it’s been 50C (122F) and hotter in many inland towns across Australia over the past century. See how many are in the late 1800′s and early to mid 1900′s. You can’t blame those high records on man made global warming.  [feel free to post some old records of your own and the source reference we can check and we will update the map]
