Scientists In Alaska Find Mammoth Amounts Of Carbon In The Warming Permafrost : Goats a... - 0 views

Tom McHale on 26 Jan 18"n northern Alaska, the temperature at some permafrost sites has risen by more than 4 degrees Fahrenheit since the 1980s, the National Oceanic and Atmospheric Administration reported in November. And in recent years, many spots have reached record temperatures. "Arctic shows no sign of returning to reliably frozen region of recent past decades," NOAA wrote in its annual Arctic Report Card last year. The consequences of this warming could have ripple effects around the world. To explain why, Douglas takes me deeper down into the tunnel. "This is really an amazing feature," he says, shining his flashlight up to the ceiling. Crispy grass is dangling upside-down above our heads. "It's green grass - from 25,000 years ago," he exclaims. "It has been preserved that way for 25,000 years." The permafrost is packed with the remains of ancient life. From prehistoric grass and trees to woolly mammoths and woolly rhinoceroses, just about every creature that lived on the tundra over the past 100,000 years is buried and preserved down in the permafrost. And all this life is made of carbon. So there's a massive amount of carbon buried down here. "The permafrost contains twice as much carbon as is currently in Earth's atmosphere," Douglas says. "That's 1,600 billion metric tons." In fact, there's more carbon in the permafrost, Douglas says, than all the carbon humans have spewed into the atmosphere since the Industrial Revolution - first with steam trains, then with coal plants, cars and planes."
