Media worldwide report another "hottest year"
The report below is from a major Australian news source. Once again we have an example of how to lie with statistics. It appears to be true that ON AVERAGE, 2016 was unusually warm. But my favourite graph below shows that the warm months were all at the beginning of the year during the El Nino weather phenomenon. By the end of the year and the end of El Nino, temperatures had slumped, with December 2016 COOLER than December 2015 -- with an anomaly of 81 compared to 111 -- According to the NASA raw data here
And how sad for Australia's BOM, that they could only report that the year was only 4th hottest for Australia, Australia is a rather large lump of real-estate so the warming we are looking at is not exactly global is it?
Two amusing things to note below:
1). The high temperatures reported are nowhere in the article attributed to "climate change". The BOM know that what was at work was El Nino and not CO2 and have become too embarrassed to lie outright about it.
2). The BOM carefully define the record they are dealing with as: "the 137-year history of modern accurate and standardised meteorological observation". The point of that, of course is to avoid confronting the careful and validated 1790 observations of Watkin Tench, which show that Sydney has had near-unbearable hot temperatures long before the modern era
It's official: 2016 set another record for being the world's hottest. Three international agencies have confirmed today that last year was the hottest on record.
NASA reported that 2016 was 0.99 degrees Celsius hotter than the 20th-century average, while the US National Oceanographic and Atmospheric Administration (NOAA) called it at 0.94 degrees Celsius. NOAA also calculated that global land temperatures were 1.43 degrees Celsius higher. The UK Met Office, using its own data, also reported that 2016 is one of the two hottest years on record.
The figures vary slightly, depending on the baseline reference period used.
Heat records don't linger for long any more. 2016 surpassed the 2015 record, which surpassed the 2014 record. Three record hot years in a row sets yet another record in the 137-year history of modern accurate and standardised meteorological observation.
For Australia, the Bureau of Meteorology described 2016 as a "year of extreme events" and the fourth hottest at 0.87 degrees Celsius above the 1961-1990 average. The warming trend is clear.
BOM's key 2016 climate facts and events
Australia is already on average 8 degrees Celsius hotter than the average global land temperature, so further warming means our heat risk is far greater than for other industrialised countries.
This dangerous warming trend sends a dire warning, as average warming delivers many more extreme heat events, as we're currently seeing in Queensland and New South Wales. These are the killers.
As Australia lurches from heatwave to heatwave, the message is clear: extreme heat is the new norm - so Australia needs to get "heat smart".
In Australia the number of days per year over 35 degrees Celsius has increased and extreme temperatures have increased on average at 7 per cent per decade.
Very warm monthly maximum temperatures used to occur around 2 per cent of the time during the period 1951-1980. During 2001-2015, these happened more than 11 per cent of the time.
This trajectory of increased temperature extremes raises questions of how much heat can humans tolerate and still go about their daily business of commuting, managing domestic chores, working and keeping fit.
