Do you believe

  1. Global Warming is occuring as a direct result of Human Activity.

  2. IF Gloabal Warming is occurring it is as a result of Non-Human or Natural Processes.

    because that type of cycle is reasonably stable, and the recent warming isn't. IE the Milankovitch cycles have been around for eons and are an integral part of the system. Whats going on now is absolutely unique. Humans are digging up fossil fuels and burning them as fast as possible. The excess CO2 is a byproduct of that combustion

    speaking of which this article from just the other day describes the situation perfectly

    NASA
    http://www.livescience.com/18255-solar-cycle-climate-change-warming.html

    About the only thing thats surprising about all this information coming forward is that the science is still not able to cut through all the disinformation out there. In the US the denial rate among Joe public is about 50/50 although it is slowly improving

    I still say one if the largest factors (which for some reason is being completey ignored) is the change in the planet's color from green to black.

    It happens on roofs, parking lots and roads.

    albedo change is definitely being considered, The urban island effect and the melting of the ice caps is changing the average albedo of the planet considerably. Partly its a feedback and partly its another man made forcing agent but its definitely not being ignored, I could probably find a pile of articles on it if your interested.

    What this article isn't really touching on is that once the solar radiation is up to +0.25 watts ( height of the solar cycle ) rather than -0.25 then we'll see an increase of 1.08 watts per square meter, which is huge. At which point we're going to be really into the next big jump in temps. It should follow the Milankovitch cycles to some degree but what this article is pointing out is that the atmospheric CO2 is so high its overwhelming even that.

    I got snow covered Palm trees outback the boat. Newspaper reports the first time since 1956.
    Very cold

    the theory predicts a lot of extreme weather due to the fact that there's more energy available in the system. But overall there is a warming trend. Denver just got hit with a big up slope weather pattern. Its cold, snowy, got a couple feet actually but its not all that unusual.

    the key thing is weather VS climate. Climate shift is an average of worldwide weather events. This is just one small event in among a tidal wave of events. Thats why they always wait to years end when they can average everything out till they announce how that years climate stacked up to all the other data

    Ah ya gotta love the op ed pieces. Couldn't help but notice that it starts with improperly identifying our position in the syn cycle and goes on to focus on the HADcrut3 data set. Rather than engage in science and average all data sets, remove the highs and the lows and move forward from there. Clearly that was another opinion piece cherry picking the data.

    Sorry but I wish you were correct on this one, unfortunately we are most definitely screwing up our atmospheric chemistry by altering the balance of greenhouse gasses

    cheers

    It isn't green or black in Boston's town now.

    How deep is the snow? The real snow.

    well this one is heating up, and might just turn out to be something interesting

    http://www.bbc.co.uk/news/business-16901106

    Apparently the EU is initiating some much needed carbon pollution reform, China being the bastion of environmental concern that it is, doesn't want to play. So China has banned its airlines from paying the carbon tax. Something I'm not sure will work anyway. The EU is likely to ban Chinese air line/s from entering EU air space. Which will cause a whole host of issues down the road. If we're lucky it will initiate the long needed collapse in this free trade farce.

    In the end its the best thing that could be happening, if the EU starts using bio kerosene to fly on then its likely to be the start of an industry switch to the new and carbon neutral fuel. Assuming they can get it fired up soon enough to make a difference.

    Long story short this might just be the fight that turns the oil and gas stranglehold over the fuels industry.

    Ahem. Those of us who are British know the Daily Mail for what it is - a fanatical far-right hack rag little more credible than The Inquirer. I wouldn't put too much faith in their reporting. But reading this article, I'm astonished at the total fabrication of accepted data.

    There really wasn't ever an argument, at least not if your following the science. Its been a slow and inexorable move in one direction since CO2 was first described in the early 1600s. A discovery which was made incidentally by the burning of coal in controlled conditions.

    Arguing that a decades old individual graph representing smoothed data is somehow flawed or fake is a pretty good example of how week the arguments against the theory of Rapid Global Climate Shift really are.

    What might be convincing, assuming it ever happens, is if someone comes up with an alternative theory which incorporates as much or more of the information to date, into a working theory capable of making as accurate or better predictions as the present theory. As of yet not even a competing hypothesis has ever been forwarded within the scientific process.

    Sure crackpots push some rubbish or other on the net quite regularly but there's a reason they circumvent the peer review process, there "work" simply wouldn't survive it. Mans graph on the other hand has survived the peer review process numerous times and given the lack of alternative theories or even a competing hypothesis, I'm just not seeing any reasonable argument being made to the contrary.

    Ah! I meant to post this a couple days ago here.

    I was listening to the BBC and they has a PhD meteorologist on to explain the cold snap in Europe.

    He said it was a once in 10 or 20 years situation.

    There is some oddball high pressure system up in the arctic, between Europe and North America. That system is responsible for the odd weather on both sides of the Atlantic.

    The high pressure system is pulling Siberian air down over continental Europe. That's why it's so cold.

    The same system is allowing warmer air to stay more north in North America, which explains our mild winter.

    He said the two odd weather patterns are the result of the single rare high pressure over the Arctic.

    Thought maybe that would be relevant to this thread, since the extreme cold and extreme warm, in his words, are "weather events, not climate events."
