and I'll bet that's because in summer, it's warmer?ice melts in summer...

so where did all that carbon come from?The effect of permafrost thaw on old carbon release and net carbon exchange from tundra : Abstract : Nature
Permafrost soils in boreal and Arctic ecosystems store almost twice as much carbon1, 2 as is currently present in the atmosphere3. Permafrost thaw and the microbial decomposition of previously frozen organic carbon is considered one of the most likely positive climate feedbacks from terrestrial ecosystems to the atmosphere in a warmer world1, 2, 4, 5, 6, 7. The rate of carbon release from permafrost soils is highly uncertain, but it is crucial for predicting the strength and timing of this carbon-cycle feedback effect, and thus how important permafrost thaw will be for climate change this century and beyond1, 2, 4, 5, 6, 7. Sustained transfers of carbon to the atmosphere that could cause a significant positive feedback to climate change must come from old carbon, which forms the bulk of the permafrost carbon pool that accumulated over thousands of years8, 9,10, 11. Here we measure net ecosystem carbon exchange and the radiocarbon age of ecosystem respiration in a tundra landscape undergoing permafrost thaw12 to determine the influence of old carbon loss on ecosystem carbon balance. We find that areas that thawed over the past 15 years had 40 per cent more annual losses of old carbon than minimally thawed areas, but had overall net ecosystem carbon uptake as increased plant growth offset these losses. In contrast, areas that thawed decades earlier lost even more old carbon, a 78 per cent increase over minimally thawed areas; this old carbon loss contributed to overall net ecosystem carbon release despite increased plant growth. Our data document significant losses of soil carbon with permafrost thaw that, over decadal timescales, overwhelms increased plant carbon uptake13, 14, 15 at rates that could make permafrost a large biospheric carbon source in a warmer world
What researchers are stating.
what is it that was settled?People on a message board entrenched in fantasy are not worth the effort.
Scientists settled the science 15 years ago. Global Warming is real and accelerating.
There is no debate.

Science is definitely not settled. ALL of the initial projections and prophecies of doom are failing -- and the ACTUAL numbers for future temperature and disaster are currently being revised WAY down from what they were 15 years ago.
The skeptics have already won without a debate. Debate was never formally allowed. That should tell you something right there. GW is killing itself quite nicely -- thank-you...
Course, could be too the dooms that didn't come true didn't because of measures taken to prevent them as with granting the premise and reducing emissions and the like.
That's a weird statement. "Granting the premise -- and the like" is enough to deter Global Warming?
CO2 is STILL rising.. The temps? Not so much.. Check the man-made emissions for yourself. China is building out about 3 coal plants per month.
Ya, those rising temps in Alaska thawing their permafrost really cast doubt on whether it's getting warmer.
"LONDON, 17 October, 2014 − If you doubt that parts of the planet really are warming, talk to residents of Barrow, the Alaskan town that is the most northerly settlement in the US.
In the last 34 years, the average October temperature in Barrow has risen by more than 7°C − an increase that, on its own, makes a mockery of international efforts to prevent global temperatures from rising more than 2°C above their pre-industrial level.
A study by scientists at the University of Alaska Fairbanks analysed several decades of weather information. These show that temperature trends are closely linked to sea ice concentrations, which have been recorded since 1979, when accurate satellite measurements began.
The study, published in the Open Atmospheric Science Journal, traces what has happened to average annual and monthly temperatures in Barrow from 1979 to 2012.
Most striking
In that period, the average annual temperature rose by 2.7°C. But the November increase was far higher − more than six degrees. And October was the most striking of all, with the month’s average temperature 7.2°C higher in 2012 than in 1979.
Gerd Wendler, the lead author of the study and a professor emeritus at the university’s International Arctic Research Center, said he was “astonished”. He told the Alaska Dispatch News: “I think I have never, anywhere, seen such a large increase in temperature over such a short period.”"

I guess I am. I deny that the warmers know anything about climate.and I'll bet that's because in summer, it's warmer?ice melts in summer...
Wow
Just fucking wow
DENIER!!!
agreed. Sadly, the denier hate of evidence is on full display in this threadShould learn how to read. Just sad when people can't then try and debate those who can.
ROFL; rich irony indeed.
Obviously you failed to read beyond the dishonest headline.
The permafrost is not melting, but the priests of your filthy religion have computer models that say it will melt.
{
The permafrost in much of Interior Alaska is already just a degree or two below the freezing point, he said, with warming expected to continue in the decades ahead.
“A degree or two warming of climate makes a big difference in our world,” he said, adding that computer modeling shows more warming in the future.
"This amount of warming can take Alaska from being frozen to being thawed,” he said, with glaciers turned into water and permafrost into thawed ground.}
Just the usual fucking lying from the usual AGW scumbags.
Notice you can't have a discussion abotu something without resorting to profanity and personal attacks. I've always assumed that was the refuge of the clueless and immature.
It is melting as subsiding ground and topple structures built originally on level ground proves. Wanna shout at the rain go ahead. Just making yourself look unmeasured and irrational. Might get polite applause but it's only ever going to be to get you to quit talking.
