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 you don't want to be convinced, not even a shot in the face will convince you that firearms can be dangerous. So it goes with anything else.
No, there's not.
Some compelling evidence, yes, but I've seen nothing that's convincing.
Peer reviewed research? There is oodles of it, check out TFA for one of them.
Of course some probably are more easily convinced than others.
I can't argue with that, you conspiricy theory types are the most gullible people on the planet, all you need is a badly written website, a few poorly researched facts and people like you will believe anything.
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.
This is an interesting question that a lot of the evangelists don't know. In interviews and debates, it's a good question to ask.
The answer is: about 1/3 of the noted increase in temperature is directly due to humans, about 1/3 is the result of natural variation, and 1/3 is unaccounted for.
Of course this is a statistical measure, sort of like trying to determine whether throwing 4 heads in a row was a fluke or an indication of a trend, but it's the best answer we have with our current understanding and datasets.
It's interesting to point out the differences between science and, for example, religion.
How does religion typically deal with sceptics and dissenters? Usually with scorn, derision, excommunication, and occasionally death. In the bible it says "shall not suffer a witch to live", and so on.
Science is the complete opposite of religion. Scientists would never ostracise, belittle, or spew hatred on sceptics, would never blackball, blackmail, or threaten other scientists, would never cause them to lose income or hold an undergraduates' opinions hostage as a condition for getting a degree.
So when you read that 97% of scientists believe in global warming, you can tell that they come to that opinion honestly, and without coercion from other scientists.
Science is completely unlike religion.
It would just mean more money to fuel Al Gore's private jet and lavish lifestyle which currently includes a 20 bedroom, 12 bath mansion with 10 car garage in Tennessee. Additionally he also owns an oceanside villa in Malibu, and a personal ski lodge in Vail. If that weren't enough, he also has a luxury condo in South Beach! Fight global warming!
You can explain these results quite simply. People in countries that have benefited greatly from causing climate change through the emission of CO2 are less willing to accept that their actions are the cause. People in countries where pollution is bad and the effects of climate change are more apparent are more likely to accept it.
Japan is an outlier because people there tend to accept expert opinion and broad scientific consensus, rather than assume they know better or that it's some giant conspiracy theory. If you look at the rest of the countries where people are skeptical, it's obviously Dunning-Kruger at work. Most of the people who think they are "experts" on climate change really just googled a load of conspiracy theory web sites and enjoyed the confirmation that their 20 MPG SUV isn't the problem.
