Inevitably, when even satellite temperatures were showing 2016 as “the hottest year on record”, we were going to be told last winter that the Arctic ice was at its lowest extent ever. Sure enough, before Christmas, a report from the US National Oceanic and Atmospheric Administration was greeted with such headlines as “Hottest Arctic on record triggers massive ice melt”. In March we had the BBC trumpeting another study that blamed vanishing Arctic ice as the cause of weather which led to the worst-ever smog in Beijing, warning that it “could even threaten the Beijing Winter Olympics in 2022”.
But last week we were brought back to earth by the Danish Meteorological Institute (DMI), as charted by our friend Paul Homewood on his blog Notalotofpeopleknowthat, with the news that ever since December temperatures in the Arctic have consistently been lower than minus 20 C. In April the extent of Arctic sea ice was back to where it was in April 13 years ago. Furthermore, whereas in 2008 most of the ice was extremely thin, this year most has been at least two metres thick. The Greenland ice cap last winter increased in volume faster than at any time for years.
As for those record temperatures brought in 2016 by an exceptionally strong El Niño, the satellites now show that in recent months global temperatures have plummeted by more that 0.6 degrees: just as happened 17 years ago after a similarly strong El Niño had also made 1998 the “hottest year on record”.
This means the global temperature trend has now shown no further warming for 19 years. But the BBC won’t be telling us any of this. And we are still stuck with that insanely damaging Climate Change Act, which in this election will scarcely get a mention. (bold added)Whether the planet is warming or cooling, are man's carbon dioxide emissions to blame?
Look at these facts: (link)
- CO2 levels are today, among the lowest in the past 600 million years.
- CO2 levels were higher than today in 85% of the past 600 million years.
- CO2 levels were as much as 20 times higher in the geological past.
- CO2 levels were at least 5 times higher than today in the dinosaur period.
- There were three ice ages with more CO2 than today, one had fifteen times more.
- CO2 has never been observed in the geological record to be a driver of the climate, even when levels were significantly higher than today.
- CO2, by itself, can not cause much warming. For there to be dangerous warming, other things must occur, which would accelerate the warming, called positive feedbacks. The most likely is increased atmospheric water vapor. Positive feedbacks have not been observed to exist in the past and when CO2 levels were significantly higher than today. Atmospheric humidity is also actually in decline. link
- Global temperatures were mostly warmer than today in the prior 8,000 years, the Holocene. link
