Climate Change Is Altering Global Air Currents (independent.co.uk)
An anonymous reader quotes a report from The Independent: One of the scientists who demonstrated conclusively that global warming was an unnatural event with the famous "hockey stick" graph is now warning that giant jetstreams which circle the planet are being altered by climate change. Jetstreams are influenced by the difference in temperatures between the Arctic and the equator. But the Arctic has been warming much faster than tropical climates -- the island of Svalbard, for example was 6.5 degrees celsius warmer last year compared to the average between 1961 and 1990. The land has also been warming faster than the sea. Both of those factors were changing the flow of these major air currents to create "extreme meanders" which were helping to cause "extreme weather events", Professor Michael Mann said. In a paper in the journal Scientific Reports, Professor Mann and other researchers wrote that evidence of the effect of climate change on the jetstreams had "only recently emerged from the background noise of natural variability." They said that projections of the effect on the jetstreams in "state-of-the-art" climate models were "mirrored" in "multiple" actual temperature measurements. The jetstream normally flows reasonably consistently around the planet, but can develop loops extending north and south. The researchers, who studied temperature records going back to 1870 as well as satellite data, said these loops could grow "very large" or even "grind to a halt" rather than moving from west to east. The effect has been most pronounced during the past 40 years, they found.
If climate change is real, why is there no peer-reviewed research that shows it?
You are welcome on my lawn.
As the climate is always changing, and Mr. Hockey Stick says it's man doing it. how much is man doing it and how did he prove that? If climate change is accelerating because of what man is doing, how much acceleration can they account for? In what way did they come up with their numbers? Rather than telling me all about the end of days, tell me about real science and hard numbers please.
Make the most of this summer because it could be your last decent one: winter is coming as the planet enters the most devastating cooling period since the 65-year Maunder Minimum of the 17th and early 18th centuries.
This is the dire forecast of Professor Valentina Zharkova, a solar physicist at Northumbria University, who has based her prediction on sun spot activity – known to be a significant driver of global climate – which is currently very low and likely to get even lower during the next three solar cycles.
She has spoken about her research and her battle to get it taken seriously by the climate establishment in an interview with the Global Warming Policy Forum. You can see it in this short film.
What can't it do? If I buy now will you throw in it's effect on the radius of gopher holes, all for the low, low price of a carbon tax?
We are currently in a period of temporary warming due to the high amount of mid-20th century solar activity. Our conditions in the current period are identical to temporary warming known as the Medieval Warming. Now just as then, global temperatures are controlled by the sun and solar activity.
We are now entering a era of minimal solar activity, identical to the Maunder Minimum which brought about the horrible period of death, disease, and famine known as the Little Ice Age. If history and science has anything to say in the matter, we should be consuming more carbon fuels, and engaging in an expansion of carbon emissions in order to stave off another ice age, another epoch of frozen crops, famine, disease, plague, and death.
Uh, you're on Slashdot, the most untrustworthy site of them all.
Seriously, getting sick and tired of hearing these whacked out lies that mankind is somehow responsible for global warming. So far there has been zero evidence to support that claim and plenty to counter it.
