All in all, the IPCC models do an impressive job accurately representing and projecting changes in the global climate, contrary to contrarian claims. In fact, the IPCC global surface warming projections have performed much better than predictions made by climate contrarians . It's important to remember that weather predictions and climate predictions are very different. It's harder to predict the weather further into the future. With climate predictions, it's short-term variability (like unpredictable ocean cycles) that makes predictions difficult. They actually do better predicting climate changes several decades into the future, during which time the short-term fluctuations average out. That's why climate models have a hard time predicting changes over 10–15 years, but do very well with predictions several decades into the future, as the IPCC illustrates.
BEIJING — China plans to introduce its national market for carbon permit trading in 2016, a government official said on Sunday, adding that Beijing is close to completing rules for what will be the world’s biggest emissions trading program. The nation accounts for nearly 30 percent of global greenhouse gas emissions, and it plans to use the carbon market to slow its rapid growth in climate-changing emissions. China has pledged to reduce the amount of carbon it emits per unit of its gross domestic product to 40 to 45 percent below its 2005 levels by 2020. It has already introduced seven regional pilot markets in a bid to gain experience ahead of a nationwide program. “We will send over the national market regulations to the State Council for approval by the end of the year,” Sun Cuihua, a senior climate official with the National Development and Reform Commission, told a conference in Beijing on Sunday. The national market will start in 2016, although some provinces would be allowed to start later if they lacked the technical infrastructure to participate from the outset, she said. The Chinese market, when fully functional, would dwarf the European emissions trading system, which is now the world’s biggest.
Hey fecal-face, you claimed that the global warming propagandist, consensus pushers never made a claim that that the artic would be ice free. You made this claim. Since a large portion of the arctic is comprised of an ocean, it is pretty easy to come to the correct conclusion, that these frauds are talking about sea ice. Futurecurrents said "No the Arctic was not supposed to be ice free". You made this false statement and its a lie. For far too long, liars like you were allowed to spew their disinformation, and nobody challenged. Those days are over.
The Arctic was not supposed to be ice free. This is the IPCC model. You fucking idiot. Do you know how to read a chart.
From Gore's speech: Last September 21 (2007), as the Northern Hemisphere tilted away from the sun, scientists reported with unprecedented distress that the North Polar ice cap is "falling off a cliff." One study estimated that it could be completely gone during summer in less than 22 years. Another new study, to be presented by U.S. Navy researchers later this week, warns it could happen in as little as 7 years.2 And yes, the deniers cannot even add. Not only did Gore not say "by 2013," but it would be 2014 at the soonest. ... On to reality: The Navy researcher that leads this "new study" team that the former vice president alludes to is Wieslaw Maslowski at the Naval Post Graduate School in Monterey, California. The team's research was funded by the Department of Energy (DOE), the Office of Naval Research (ONR), the National Science Foundation (NSF), the National Aeronautics and Space Administration (NASA) and the National Oceanic and Atmospheric Administration (NOAA). Maslowski also did not say "by 2013" in his original research in 2007 or when it was republished in 2009. This grandstanding about sea ice and Gore, for whatever reason, is a huge and egregious deception. The actual prediction from Maslowski's 2009 publication is, "Autumn could become near ice free between 2011 and 2016."3
The Arctic is Already Functionally Ice-Free It has happened, just as the scientists said it would happen. Only, like almost everything else in climate science, a functionally ice-free Arctic Ocean has happened a little bit ahead of the earliest prediction. Arctic sea ice was first deemed "almost seasonally ice free" in summer 2010 by professor David Barber. Barber is professor of environment and geography, Canada's research chair in Arctic system science and director of the Centre for Earth Observation Science (CEOS) at the University of Manitoba, in Winnipeg. Dr. Barber has been searching for 200-foot thick multiyear Arctic sea ice in the Beaufort Sea, an area of the Arctic Ocean that stretches for almost 1,000 miles along the coasts of Alaska and Canada. For his research in summer 2010, he cruised through the Beaufort Sea in the ice breaker Amundsen and never did find that multiyear ice. What Barber's team did find was vastly different from what the satellites were telling them was there. They thought they would find 20- to 30-foot thick multiyear ice covering 7 percent to 9 percent of the Beaufort Sea. Instead, they found 25 percent open water and very small remnant multiyear and first-year floes interspersed with thin new ice in between. Unfortunately, these satellite errors are not in our favor. The problem is because these conditions are new. They simply have not existed before, so there was no way to test for them and know that this sea icescape looks, to the eye of the satellite, exactly like a sea icescape that is thick and solid.7 The ice the Amundsen encountered was so rotten that it did not impede the forward progress of the ship. What they found was hundreds of miles of what Barber called "rotten ice." This was 20-inch layers of fresh ice covering small chunks of older ice.8This discovery came as a great surprise to this researcher as he cruised through the rotten ice of the Beaufort Sea at 14 miles per hour (the top speed of his vessel in open water is 15 miles per hour). The Amundsen was designed to break 1-meter thick sea ice (3.3 feet) at 3.4 miles per hour. The ice they found was so rotten that the Amundsen could break 19 to 26 feet of rotten multiyear ice at 5.7 miles per hour.9 This fascinating tale was from summer 2010, remember. Carbon dioxide continues to accumulate; physics marches on. Northwest Passage exploration of this new millennia has left us with these quotes from Barber attesting to this brave new world we have created for ourselves: "Ship navigation across the pole is imminent as the type of ice which resides there is no longer a barrier to [normal] ships in the late summer and fall,"10 "If you want to ship across the pole, you're concerned about multiyear sea ice. You're not concerned about this rotten stuff we we're doing 13 knots through. It's easy to navigate through. I would argue that we almost have a seasonally ice-free Arctic now, because multiyear sea ice is the barrier to the use and development of the Arctic."11 The recent record-breaking Arctic sea ice melt season has even greater significance if a few more details are understood. The 2007 record, which broke the recently set 2005 record by 22 percent, was considered a freak weather occurrence in the popular literature. This was because an unusual (for our old climate) weather system set up over the Arctic in summer 2007. Warmer-than normal-temperatures and high winds combined to reduce sea ice that year. The winds pushed ice up against Canada and out of the Arctic into the North Atlantic and down the Fram Straight to the east of Greenland. This weather system may or may not be unusual in our new climate.
