    On the trail of the Arctic’s carbon time bomb - Another conspiracy of stupid scientis

    Great news for the defenders that the raise of carbon is very positive and it has any effect. As you know, after having read a little more, I am convinced they are right. So I believe that the scientists are pure alarmists and they are exagerating and they should not be worried about the fires in the Artic and how it affects to the permafrost that is containing the Artic's carbon.

    Source: Thenewscientist

    ON A July afternoon in the eastern Siberian town of Cherskiy, 220 kilometres north of the Arctic circle, it is a warm 27 °C. The vista features silver-blue rivers bisecting green swathes of boreal forest – Earth’s biggest ecosystem. But drive a metal rod into the soil and roughly 75 centimetres below the surface you hit a layer that’s as hard as steel – and perhaps as dangerous as dynamite.
    Arctic permafrost holds more than twice as much carbon in its frozen soil as Earth’s atmosphere. Which is what brings me here, accompanying seven US scientists from various labs, led by the Woods Hole Research Center in Falmouth, Massachusetts. We have travelled 7000 kilometres and 15 time zones to Cherskiy to study a phenomenon that might hasten the release of that carbon: the rise of Arctic wildfires.
    “Welcome to Cherskiy,” our host Nikita Zimov says minutes after we disembark the Antonov-24 propeller plane that brought us here. Zimov directs the Northeast Science Station. “I understand you want me to take you to that hellhole,” he says as he points to a ghost of a forest that will soon enchant the scientists, despite its bugs, muck and fallen trees.

    I thought we were arguing about CO2, not carbon.

    Scientists are very worried about it. Most of them.

    And about the CO2. It has direct impact in the cycle of the carbon. And it has consequences.

    Uncle Ferd says it's due to a split jet stream...

    'Unprecedented' Jet Stream Pushing Warm Air Into Arctic
    February 08, 2017 - For the second consecutive year, the northern reaches of the planet are experiencing unprecedented waves of warm air. And climate researchers say they've never seen anything like it.
    Unprecedented warm weather

    To try and understand what is going on, VOA spoke with Mark Serreze, the director of the National Snow and Ice Data Center (NSIDC) based in Denver, Colorado. The center does all kinds of things, from helping the Navy spot and avoid sea ice, to monitoring the temperatures, weather systems and extent of the sea ice covering the Arctic and Antarctic throughout the year. The weather pattern of the past two years, according to Serreze, is "unprecedented in my memory."


    Polar bear and cubs in the Arctic

    The unprecedented part is what Serreze calls "pulses of extremely warm air over the [Arctic] Ocean, extreme to the point where at the North Pole it's getting near to the freezing point." The cause is "an unusual jet stream pattern that has helped to guide lots of very strong storms into the Arctic, coming in from the Atlantic" Ocean. Jet streams are narrow bands of air that move extremely fast around the globe. The polar jets are the strongest, circling the globe between nine and 12 kilometers above sea level. They can move at more than 100 kilometers per hour.

    This winter and last, those polar jets are doing what they always do, picking up a lot of hot moist air from the tropics and pushing it up into the arctic. That's how weather works, Serreze says, moving warm, moist energetic air from the lower latitudes near the equator to higher latitudes at the poles to cool down and release all that energy. The difference here, he says, is we're experiencing an unusually strong jet stream, combined with unusually strong storms. That combination is creating these pulses of very warm weather.

    New normal, or just weather?

    Global warming melting Arctic sea ice...

    Study: Arctic Sea Ice May Be Shrinking Faster Than Thought
    October 24, 2017 — Arctic sea ice may be thinning faster than predicted because salty snow on the surface of the ice skews the accuracy of satellite measurements, a new
    study from the University of Calgary said on Tuesday.

    The report from the Canadian university's Cryosphere Climate Research Group published in the academic journal Geophysical Research Letters found satellite estimates for the thickness of seasonal sea ice have been overestimated by up to 25 percent. That means the Arctic Ocean could be ice-free much sooner than some scientific predictions, which forecast sea ice will first disappear completely during summer months between 2040 and 2050, according to lead author Vishnu Nandan.


    Ice-free summers in the Arctic Ocean would impact global weather patterns by increasing the magnitude and frequency of major storms, and alter the Arctic marine ecosystem, making it harder for animals like polar bears to hunt.

    There are a wide range of projections as to when Arctic sea ice will start disappearing in summertime as a result of warming global temperatures, and the University of Calgary study calls into question satellite measurements provided so far. "The problem is, microwave measurements from satellites don't penetrate the salty snow very well, so the satellite is not measuring the proper sea ice freeboard and the satellite readings overestimate the thickness of the ice," Nandan said.


    The sea ice freeboard refers to ice that can be seen above sea level and co-researcher John Yackel said, "Our results suggest that snow salinity should be considered in all future estimates on the Arctic seasonal ice freeboard made from satellites."

    Question

    Granny says, "Dat's right - it's `cause o' dat global warmin'...

    Warming Arctic, Drier Regions, and Wildfires: Is There a Link?
    December 09, 2017 — Many scientists believe the Arctic, one of the fastest-changing places on the planet, could drive change in other parts of the world, including wildfire-ravaged Southern California.
    In a recent NASA mission called Oceans Melting Greenland (OMG), climate scientist Josh Willis embarked on a journey to study ice in Greenland and surrounding oceans and how much oceans are eating away at the ice around the edges of the ice sheet. The data collected included the ocean’s temperature and salinity, and the shape and depth of the sea floor. “The shape of the sea floor determines how much the warm water can reach in and touch the glaciers,” said Willis, who works at NASA’s Jet Propulsion Laboratory near Los Angeles. “Warm water is widespread across the Greenland shelf, and it is very much a major threat to the glaciers,” Willis said. “The thing we really don’t know is how fast is Greenland’s ice going to disappear. “If it takes a thousand years or two thousand years, then we can probably adapt. But if it happens in a few hundred, we should already be evacuating cities around the world,” he added.

    Impact of sea ice

    A separate study from Lawrence Livermore National Laboratory suggests a link between sea ice melting in the Arctic and drier conditions in California. A new simulation that only looks at sea ice in the next two decades, shows a pressure ridge pushing the winter air masses north into Alaska and Canada, which impacts California. “We saw quite substantial drying of California so with (looking at) the sea ice alone, we saw 10 to 15 percent decrease in precipitation over a 20-year period,” said Ivana Cvijanovic, an atmospheric scientist and post-doctoral researcher at the national laboratory.

    Other factors such as greenhouse gases and particulate pollution can also affect the future of rainfall in California. The modeling framework used in the study at Lawrence Livermore helps scientists understand the impact of sea ice in isolation to these other factors. “Ice is disappearing on the Arctic Ocean. It’s disappearing from Greenland and this is reshaping climate patterns all across the planet,” Willis said. He and other scientists predict that as Arctic regions warm, the American Southwest will feel the impact. “We will probably see drier conditions in the long run in the second half of the [21st] century in the Southwest and that means we’re going to struggle with water needs and also fire,” Willis said.

    Intersection of wildland, people

    Dry conditions plus a growing population and urban sprawl equals more wildfires and costly devastation, such as the ones in Southern California. “We are in Southern California and a lot of the fires we find that happen right where people intersect with wildland happen because of people,” said Natasha Stavros, an applied science system engineer and fire expert at NASA’s Jet Propulsion Laboratory. As the weather evolves and more wildfires burn, Stavros expects other environmental changes. “As we experience climate changes and things become hotter and dryer, fire acts kind of like an eraser. It erases the landscape and it actually allows new ecosystems to establish because they don’t have to compete with what was there,” Stavros said.

    The American Southwest is not the only place where change is predicted. “As the atmosphere heats up, it becomes a better pipe for carrying water for picking it up from one place and dumping it in another,” Willis said. “This means that dry places are more likely to get drier and wet places are likely to get wetter. It also means that bigger more torrential downpours become more likely.”

    California Governor: Late-year Wildfires are 'New Normal'
    December 09, 2017 - California Governor Jerry Brown cautioned Saturday that more wildfires were in his state's future, as firefighters battled six major blazes that have killed at least one person and damaged hundreds of homes.
    Brown surveyed fire damage in Ventura County, just north of Los Angeles, the scene of some of the worst destruction of the past week. "This is the new normal," he said, blaming climate change for the increased danger of wildfires late in the year. "We're facing a new reality in the state where fires threaten people's lives, their property, their neighborhoods, and of course billions and billions of dollars" in damage, Brown told reporters. Late Friday, officials said they had linked the death of a 70-year-old woman in a car accident to the fires. Ventura County medical examiner Christopher Young said Virginia Pesola was fleeing the Thomas Fire in her car, following an evacuation route, when she crashed and died. Young said the cause of death was blunt force injuries and smoke inhalation.


    California Gov. Jerry Brown discusses the Thomas Fire and the extended length of the state's fire season during a press conference Dec. 9, 2017, in Ventura, Calif.

    About 87,000 people remained evacuated from their homes, down from a height of more than 200,000 earlier this week. Since Monday, the fires have burned more than 670 square kilometers (260 square miles). New fires keep erupting in dry conditions, though, and are being stoked by relentless westward Santa Ana winds, which are expected to gust up to 80 kilometers per hour (50 mph) on Sunday. About 8,700 firefighters, accompanied by helicopters, continued to spray and dump water and fire retardant to try to slow the spread of the blazes that have erupted along the Pacific Coast from San Diego to Santa Barbara County, about 370 kilometers (230 miles) to the north. President Donald Trump responded to the fires Friday by issuing a federal declaration of a state of emergency for California, paving the way for federal agencies to help coordinate relief efforts.

    The biggest and most destructive blaze is the Thomas Fire, about 90 kilometers (56 miles) northwest of Los Angeles. It has charred nearly 580 square kilometers (224 square miles) and destroyed nearly 440 structures. As firefighters made progress against the Los Angeles-area fires, most evacuation orders were lifted. One of the newer blazes, the Lilac Fire, broke out Thursday in San Diego County, more than 200 kilometers (125 miles) south of Los Angeles. The fire burned 16 square kilometers (6 square miles) in mere hours as it swept through the densely populated Rancho Monserate Country Club community and the small city of Fallbrook, home to numerous horse ranches and avocado orchards. Officials said 85 structures were quickly destroyed.

    Officials said a smaller fire erupted Friday in San Diego County, about 50 kilometers (31 miles) east of downtown San Diego. They said the fire was small compared with the Lilac Fire and that numerous resources would be sent to fight it. Fires are not uncommon in Southern California this time of year, before the winter rains set in, when the vegetation is tinder dry and winds blast the region. This year, however, has been particularly bad for California fires because of dry, hot and windy conditions that would be extreme for any season, including the winter season that is just two weeks away. Just weeks ago, wildfires that broke out in Northern California killed 44 people and destroyed 8,900 homes and other buildings.​
