Tell the world, 2015 is the hottest year since 2010.
The fuss made over contested decimal points in highly adjusted datasets of irrelevant factors only shows how unscientific the public debate is. It probably wasn’t the hottest year in the last 150, and even it was, who cares — that doesn’t tell us anything about the cause. (Remember when cause and effect used to matter to a scientist?) Natural forces like the Sun and clouds can cause hot years too. Even if it was “the hottest” in a short noisy segment, the world has been hotter before (and life on Earth thrived) and the climate models are still hopelessly wrong. If CO2 was a big driver of the climate, 2015 should have been a lot hotter.
1. It wasn’t the hottest year. Satellites have better, broader coverage, surveying almost the whole planet (rather than selected car parks, runways, etc. like the surface thermometers). The satellites say that both 1998 and 2010 were hotter. In any case, these kind of piddling noisy differences are just street signs on the road to nowhere — what matters are the long term trends, and the predictions of climate models. (If the models worked, […]
NOAA has a press release out being picked up around the world. For example, the DailyMail, UK, is saying July was the hottest month since records began in 1880 as heatwaves swept the Earth’s countries and oceans. Other silly tabloids have headlines about this being the hottest July in 4,000 years, as if we have even the remotest idea what the average July global temperature was in the days of Plato.
Better data shows July this year is the hottest since way back in… 2014. It’s not 4,000 years, not 135 years, it’s the hottest July since the last one. We only have 30 years of good climate data: the satellites tell us the pause is real, and last month’s summer temperatures is not a record anything. According to the UAH and RSS global satellites, lower troposphere averages for July 2014 were 0.30C and 0.34C, compared to July 2015 of 0.28C. Even, June 2015 was hotter (UAH, 0.35C; RSS, 0.39C). July 2015 is not even the hottest month since June.
But some journalists will believe anything. Anthony Sharman, sports journalist, News.com, Australia, thinks we know the global temperature of the July that Jesus was born. Who’s a gullible journalist then? […]
I guess it is winter. In a cold snap last week nearly 1,400 records were broken in the US. 886 places recorded the lowest maximum, 325 recorded the coldest minimum, and 127 places recorded the highest snowfall.
…
Source: Hamweather
Total Records: 1,379 Snowfall: 127 High Temp: 28 Low Temp: 325 Low Max Temp: 886 High Min Temp: 13
A few days ago the records for that seven day period were even higher: 205 snowfall records. 969 Low Max. 203 Low temps. 17 High Temp. 61 High minimum.
Media coverage of the record cold? Almost non-existent
A search for news of cold records set in US from Nov 26 to Nov 30 turns up one story in the Christian Science Monitor and pretty much no where else (did I miss some?). When 1,000 heat records fell in a week USA today covered it. They don’t seem to have mentioned the cold records, but we might wonder whether that’s an editorial bias, or (I think more likely) that no official climate or meteorological group issued a press release.
More cold is apparently on the way, look at the forecast map: 10 out of 10 […]
