Arctic permafrost is melting faster than predicted

Nov 29, 2012 | Posted by: roboblogger | Full story: New Scientist

We may be closer to a major climate tipping point than we knew. Earth's permafrost - frozen soil that covers nearly a quarter of the northern hemisphere and traps vast amounts of carbon - may be melting faster than thought and releasing more potent greenhouse gasses.

In addition, you think topix does not know what you publish. Attacks on me will not delete or erase what you are and what you do. You should stop making an ASSumption of your---self before you know the facts

Yes itís true I don't have a degree like you do. I will make an effort to learn BS so I could be just like you. Then I could post cut and paste useless scientific science fiction babble. Can you tell me what school you attended so I can be just like you?

She just sees herself as an anti-science champion, stiffling any intellectual discussion.

She should live in rural Pakistan and wear a burka-- it would fit her world view.

Did it occur to you that perhaps he doesn't want to be commander troll ?
Everyone has a character...your is aptly demonstrated in your posts...
Walloped and crapper are words that would normally be associated with a 8 to 12 year old living in a remote area of the Ozarks.
Your posts reflect a science education acquired in a two holer of years past.Perhaps its just outdated magazines...
I can dredge up a certain amount of empathy for your seeming position.
It can get better if you are willing to try

Great, there is no record of there being LESS ice by whalers prior to 1950.
They think the world might have been warmer in certain areas. You didn't have 7 billion people living on the planet and thriving civilizations depending on agriculture. The estimated population of the planet during the Holocene was around a million humans.
Guess you can fantasize you'd be one of those that survive, so who cares about the rest, did I get that right wing mindset right????
You're a "loving" person too, I bet you're going to hypocritically tell me... and it was just "their time" for those people to go ....
I
Actually there is in their logs. As for the rest, the warmer it is the more land that is availabe for agriculture and the longer the growing season. I have plants in my garden that seem to be surviving since last summer. Some things might have to change such as planting earlier and planting latter in the season. With gene engineering it could be possible for some places in the US to have crops year round. And not just the US but in other locations. There is even permifrost that is melting which is more potentional farmland.

And what it is time for people to do is change. Then again it is always time to change. Time to think about adapting. For example, England is now warm enough to support grapes. Something they have not been able to have since Roman times. More open water also means more possibilities for fishing.

You seem to have real issues with change. Upset because the climate is changing and desire to stop changes from happening. Problem is that changes have happened forever.

It is the droughts that are the bigger problem. Higher temperatures dessicate the temperature out of the ground. And higher temperatures can destroy the plant.

Were you reading ANY news last summer?

I was thinking about the fact that global warming may or may not be real, and I thought that maybe the media is exaggerating what is really happening in the environment. Would that make sense or do you think what is happening is not exaggerated at all.

Which media?

#1 The science media -- no.
#2 The popular media? They can exaggerate what is happening today (definitely true with hurricanes and polar bears),
but can even be understating the risks that we face tomorrow.

See you have to go to a science source. Try Discover, Scientific American, NewScientist.

Here are a couple of good links:

http://www.scientificamerican.com/article.cfm...

http://www.newscientist.com/article/dn11462-c...

And there are mega millions of dollars spent on right wing misinformation campaigns right now, most of it by oil and coal companies.

Happy reading! Cheers.

Don't you mean dessicate water out of the ground. And yes I have read the news last summer and did the research about drough history in that area. Maybe you heard about the dust bowl. They had a decade long drought in that general area in the 1930's.

Maybe you should also spend a little more time watching PBS or the History channel. They even have them on You Tube.

But the Dust bowl was caused as much by bad agricultural practices.

Perhaps you were unaware we have a large federal Agency today called the Agricultural Department, one of whose job is to prevent the poor farming practices that caused the DustBowl.

What I was talking about was expanded droughts brought on by global warming.

Perhaps,also you would wish to inform the science community exactly how history is now influencing climate ?
The media can hype an issue for economic gratification that's their stock and trade...that would add little to an understanding
of the mechanics of climate and to what effect man plays a role
in climate change...
History histrionics lends little to an understanding of how man can influence climate...how man influences the chemistry and physics of climate will...

This report says 1.5 C could be the point where perafrost begins to melt. NOTICE THE DATE ! At current rate of warming that gives us 70 years to find the cause.

It was agrivated by bad agracultural practices but before that drought those same practices had been providing high yields. What caused it was a long drought which dried out the soil. What made it worse was the lack of root cover. Don't forget that they also had locust which also stripped much of the plant life from the land and that includes that areas that had not been plowed or grazed.

Surprise but I am spending two nights a week now in the front of a class teaching computer science. As for history, the past always influences the future. If you do not or cannot learn the lessons from the past then you will repeat those mistakes in the future.

And while I not making the hard stuff I do make a little homemade wine from different local fruits and berries.

I've had teachers dumb as dirt.
I knew a biology teacher at a university who insisted the Grand Canyon was caused by the "special waters" of the Genesis Flood.

Good luck with your home made wine efforts though.:)

In my Space Mechanics class, the prof. was a nice Christian guy who had us calculate the possibilities of a close-approaching loosely bound cometary body & at what Earth distance it would break up from gravitational Roche limit. The reason...... whether the atmospheric phenomenon could approximate the stories about the Jewish withdrawal from Egypt, including the parting of the Red Sea.

My grandpa used to make wine from the plum tree in the front yard. He had the large glass bottles, curly tubes & everything.
