Jo Nova has a must read article on the first ever audit of the HADCRUT temperature records
It’s based on the doctoral thesis of John McLean who found a pile of steaming detritus where the world’s top scientists had been. A month in Romania at -45°C; 3 months in Colombia at 80°C; sea temperature readings hundreds of miles inland: it’s all in the data base, and no-one noticed until a PhD student took a look at the figures. Read it, buy the book for eight Australian dollars, and reflect on the folly of the world’s first outbreak of global scientific mass hysteria.
If dangerous global warming was a court case, the judge would throw it out. If it was a company quoted on the stock exchange, the board would be facing prison sentences. A historian who changed data from a century ago would face ridicule and ostracism. But hey, it’s only science.
We knew already that NOAA’s fiddling with historical data pushed temperature rise for the twentieth century up from about half a degree to one degree. If they hadn’t done that, the dangerous effects of warming already evident which the IPCC will announce today would have been due to only half the rise they are currently attributed to. Which means the danger would have been half as great. At current rates of adjustment, by 2040 the 20th century rise in temperature will be seen to have been 2°C, making the effects of a further one degree rise negligible.
Oh well. Today is the IPCC’s big day. The news is full of pictures of wildfires and polar bears. Let’s not rain on their parade. Enjoy it while it lasts, until we’re overwhelmed by the rising tides of the millions of climate refugees.
