NOAA: Arctic changes are affecting climate elsewhere

Changes such as a decrease in sea ice have consequences elsewhere, the report says.

The Arctic's warming trend is beginning to affect the climate farther south, the National Oceanic and Atmospheric Administration said this week in its annual Arctic Report Card.

"There is evidence that the effect of higher air temperatures in the lower Arctic atmosphere in fall is contributing to changes in the atmospheric circulation in both the Arctic and northern mid-latitudes," wrote the report's authors, a team of 69 international scientists.

Extreme cold and big snowfalls can be blamed on the Arctic changes, according to NOAA.

"Beyond affecting the humans and wildlife that call the area home, the Arctic's warmer temperatures and decreases in permafrost, snow cover, glaciers and sea ice also have wide-ranging consequences for the physical and biological systems in other parts of the world," NOAA Administrator Jane Lubchenco said.

Sea ice reaches its minimum in September every year. This year's September ice cover was the third-smallest recorded since microwave satellites started taking measurements in 1979, the authors wrote.

"The last four summers have experienced the four lowest minimums in the satellite record, and eight of the 10 lowest minimums have occurred during the last decade," the report card said.

The sea ice also appears to be much younger than two decades ago, as ice that survived from year to year has dwindled to a fraction of its former mass, the data showed.

Greenland, the Arctic's great glacier-covered land mass, experienced record-setting high air temperatures, ice loss and glacier area loss, the report said.

"A combination of a warm and dry 2009-2010 winter and the very warm summer resulted in the highest melt rate since at least 1958 and an area and duration of ice sheet melting that was above any previous year on record since at least 1978," the authors wrote.

Furthermore, "a clear pattern of exceptional and record-setting warm air temperatures is evident at long-term meteorological stations around Greenland," they wrote.

    How can this climate change be happening??? Conservatives say that there is no such thing as "global warming" or a changing environment due to human activity. And, if the Right says it doesn't exist....well....then these Yale, Harvard, and MIT-trained scientists have ALL got to be wrong! Yeah! (Heck, we will find Manhattan Island to be eventually covered in water due to the melting ice caps, yet the Right will STILL blame it on something like "a leaky sewer!")

      Remember, Everyone thought the world was flat also. This climate change stuff, is more like a religon, you believe it is happening because of humans, or you don't. It's a feeling. Because science has not been around since the beginning of time. It cannot predict the future, and most reasonable peaple know that. Live your life to it's fullest, and let the planet figure it out. Your just an ant waiting to be squished.

      Do you honestly believe that there is anthing that humans can do to reverse changing weather patterns? That is like asking a fire ant colony to stop a freight train. If Manhattan is ten feet under water in a hundred years, then it shouldn't have been built in a flood zone.

    Climate Patterns change naturally.. Whether Human activity adds to the speed of this change, seems very possible.. Either way humanity needs to prepare for these changes or perish..

    If you are really worry about global warming, than stop re-producing, stop eating meat, stop driving car, stop watching television. Over population is the biggest cause and no one is addressing it since it is not PC to talk about it. We destroy the forest to make room for new cities, farm land, drill for oil to fuel our needs for energy. Solar and wind will not be able to meet all the demand for energy and we don't want to go nuclear. Well, all your eco-religious zealous, make up your mind. Put your money where your mouth is. Talk is cheap. One child per family and if you are not productive or able to contribute to society, than you must be terminated. That will take care of half or more of the earth population. Then we will not need all the car, won't have to destroy the forest, spend as much resources. Sooner or later, we will all die anyway.

      "If you are really worry about global warming, than stop re-producing, stop eating meat, stop driving car, stop watching television." Yes, and if we continue on our path of denial, it seems those luxuries will be taken away anyways. Your assertions are inadequate because they suggest a false dilemma between the current state of living and utter poverty. Somewhere in between there is a sustainable way of living without so much waste.

      Population is very close to hitting a high point, and in fact, will start to decrease in the next 10 years. Regardless if global warming is real or false, why is it so bad to clean up our air, our water, our soil? Conservatives have to take it to extremes, either "you're with us or against us" mentality, and it truly sucks. It wreaks of ignorant behavior. It would be nice to have rivers to fish, clean air to breath, and rich soil to farm.

      Sure... the end is coming. Study a little anthropology and you quickly learn that humans have believed "the end is near" at least since the beginning of recorded history. Every generation in every culture has some "provision" or caveat for the "end times." It's a part of every culture. The truth will set you free. The "end times" begin in about 4 billion years when the sun starts to burn its last remaining fuel and we're all cooked. Personally, I'm not losing sleep over it. The human race will be long-gone by then. We'll be a footnote in the history of earth and there won't be a single thing left on the planet that indicates we were ever here.

      I supposed God is the reason the ozone layer is still there to protect us from the radiation of the sun. Yeah, I'm pretty sure that a group of people got together and realize that CFC's were destroying the ozone so policy was put in place to stop the use of CFC's. Low and behold, we still have its protection.

      God does not dictate the way we handle to earth. We have free will and we can decide to destroy the earth or make it a place worth living. So don't give me this garbabe about putting all my faith in God's hands. This planet is in our hands, given by some higher power, and it is our responsiblity to take care of it. Don't be a pansy.

      Your point is empirically challenged on the God thing. Praying to God is great, but expecting him to do something independently based on your prayer and faith is broken. There are numerous occasions where praying to God have not improved the situation. The only rational conclusion is to act as if he isn't going to help. I will emphasize this is consistent with prayer. Teach a man to fish and he will live a full live. Teach a man to pray, and he will die praying for fish. Point is while prayer is great – the man still has to fish.

      Hey tx, did CFCs create a huge ozone hole? Yes it did. Was it necessary for humans to change there behavior to correct that? Yes, and we did. You can't make an argument that we would be better off if we hadn't stopped the use of CFCs.

      This debate is centered around a similar premise. The problem is that our ability to notice the change that is occurring isn't so obvious as a the giant ozone hole. But there is scientific evidence and consensus, 97% of the scientific community, which shows we are creating the warming that we are beginning to see.

    Its a cycle. Human data collection is limited to 200 years or less. On a planet that is millions of years old the fact is that we know nothing. Its like basing the outcome of a football game on the first 10 seconds. Science has been proven to be inadequate 100 percent of the time. For example, the earth revovles aroud the sun, the earth is flat and on and on. The more we learn the less we realize that we know. This is just natural phenomenon.

      Fossil fuels are basically carbon bonds that have been 'removed' from the carbon cycle. So, what happens when you pull that stored carbon up from the depths of the earth, then break the bonds and release them into the atmosphere as CO2? You increase CO2. Recall that the last time those fuels were circulating in the carbon cycle was during the carboniferous period. And we're brining it all back up, and FAST. While climate science is decidedly NOT simple, the basic chemistry is. If y'all want to be so certain you know more than all those PhD physicists out there studying climate, you ought to take graduate course in atmospheric science. I dare you.

      There is, perhaps, no greater hypocrisy than saying that Global Warming is nothign but a natural 50,000 year cycle. How do you come to the notion that it is a cycle? Well, because scientists have proven that there is a cycle of that magnitude. So , for those purposes, the scientists are right. But if a scientist says that this is a more dramatic, much shorter cycle, with clear evidence of human impact, the scientists have no idea what they are saying?!?!?!
