Ice Melt

 

What else can we expect as we negotiate our abrupt transition in climate to a much warmer world?

 

by Paul Beckwith for World Daily

 

Abrupt climate change. It is happening today, big time. The northern hemisphere atmospheric circulation system is doing its own thing, without the guidance of a stable jet stream. The jet stream is fractured into meandering and stuck streaked segments, which are hoovering up water vapor and directing it day after day to unlucky localized regions, depositing months or seasons worth of rain in only a few days, turning Road Damagethese locales into water worlds and trashing all infrastructure like houses, roads, train tracks and pipelines. Creating massive sinkholes and catastrophic landslides. And climate change is only getting warmed up.

In the Arctic methane is coming out of the thawing permafrost. Both on land and under the ocean on the sea floor. The Yedoma permafrost in Siberia is now belching out methane at greatly accelerated rates due to intense warming. The collapsing sea ice in the Arctic Ocean is exposing the open ocean to greatly increased solar absorption and turbulent mixing from wave action due to persistent cyclonic activity. Massive cyclonic activity will trash large portions of the sea ice if positioned to export broken ice via the Fram Strait.

What does it all mean? There is no new normal? Far from it. We have lost our stable climate. Likely permanently. Rates of change are greatly exceeding anything in the paleorecords. By at least 10x, and more likely >30x. We are heading to a much warmer world. The transition will be brutal for civilization.global-warming

Can we avoid this? Stop it? Probably not? At least with climate reality being suppressed by corporations and their government employees. With their relentless push for more and more fossil fuel infrastructure and mining and drilling.

Craziness, in a nutshell. Temperatures over land surfaces in the far north have been consistently over 25 C for weeks, due to persistent high pressure atmospheric blocks leading to clear skies and unblocked solar exposure. Water temperatures in rivers and streams in the far north have resulted in large fish kills as their ecological mortality thresholds have been exceeded. Many other regions are experiencing strange incidences of animal mortality. Mass migrations of animals towards the poles are occurring on land and sea, at startling rates, in an effort for more hospitable surroundings for survival. Shifting food source distributions is causing even hardier, less vulnerable species to be severely stressed. For example, dolphins are being stranded or dying, birds are dropping out of the sky, and new parasites and bacteria are proliferating with warmer temperatures.

In regions of the world undergoing severe droughts the vegetation and soils are drying and fires are exploding in size, frequency, and severity. Especially hard-hit are large regions of the US southwest, southern Europe, and large swaths of Asia. Who knows if forests that are leveled by fire will eventually be reforested; it all depends on what type of climate establishes in the region.

What about coastal regions around the world and sea levels? Not looking too good for the home team. In 2012 Greenland tossed off about 700 Gt (Gt=billion tons) of sea ice, from both melting and calving. As the ice melts it is darkening from concentrated contaminants being exposed, from much greater areas of low albedo meltwater pools, and from fresh deposits of black carbon ash from northern forest fires. Even more worrying are ominous signs of increasing movement. GPS sensor anchored to the 3 km thick glaciers hundreds of km from the coast are registering increased sliding. Meltwater moulins are chewing through the ice from the surface to the bedrock and are transporting heat downward, softening up the ice bonded to the bedrock and allowing sliding. Eventually, large chunks will slide into the ocean causing tsunamis and abrupt sea level rises. Many regions of the sea floor around Greenland are scarred from enormous calving episodes in the past.

Coastal Flooding
On a positive note, this knowledge of our changing climate threat is filtering out to greater numbers of the slumbering public that has been brainwashed into lethargy by the protectors of the status quo. As more and more people see the trees dying in their back yards and their cities and houses and roads buckling under unrelenting torrential rains they are awaking to the threat. And there will be a threshold crossed and a tipping point reached in human behavior. An understanding of the reality of the risks we face. And finally global concerted action. To slash emissions. And change our ways. And retool our economies and reset our priorities. And not take our planet for granted.

Toward Genuinely Improved Discussions of Methane & Climate

The post ‘Toward Improved Discussions of Methane & Climate’ recently appeared at SkepticalScience, in response to the recent publication in Nature of ‘Vast Costs of Arctic Change‘, by Gail Whiteman, Chris Hope, and Peter Wadhams.

shapeimage_3There is a new phenomenon in the global arena called “Climate Refugees”. A climate refugee is a person displaced by climatically induced environmental disasters. Such disasters result from incremental and rapid ecological change, resulting in increased droughts, desertification, sea level rise, and the more frequent occurrence of extreme weather events such as hurricanes, cyclones, fires, mass flooding and tornadoes. All this is causing mass global migration and border conflicts. For the first time, the Pentagon now considers climate change a national security risk and the term climate wars is being talked about in war-room like environments in Washington D.C.

An epic journey event, four years in the making. A film that is changing the way the world is looking at climate change.  Screened by

Prime Ministers, Presidents, The Pentagon, United Nations, Davos, US Embassies, universities and churches around the world.  Climate Refugees will forever change the way you view the future of our planet. via … climaterefugees.com

 

Fox News found to be a major driving force behind global warming denial

A new study published in the journal Public Understanding of Science (PDF available here) surveyed a nationally representative sample of over 1,000 Americans in 2008 and 2011 about their media consumption and beliefs about climate change.

The results suggest that conservative media consumption (specifically Fox News and Rush Limbaugh) decreases viewer trust in scientists, which in turn decreases belief that global warming is happening. In contrast, consumption of non-conservative media (specifically ABC, CBS, NBC, MSNBC, CNN, NPR, The New York Times, and The Washington Post) increases consumer trust in scientists, and in turn belief that global warming is happening.

The study also examined previous research on this issue and concluded that the conservative media creates distrust in scientists through five main methods:

America’s first climate refugees

 

It’s real, global warming, it’s real.
Nathan Tom, a Newtok resident

Sabrina Warner keeps having the same nightmare: a huge wave rearing up out of the water and crashing over her home, forcing her to swim for her life with her toddler son.

“I dream about the water coming in,” she said. The landscape in winter on the Bering Sea coast seems peaceful, the tidal wave of Warner’s nightmare trapped by snow and several feet of ice. But the calm is deceptive. Spring break-up will soon restore the Ninglick River to its full violent force.

In the dream, Warner climbs on to the roof of her small house. As the waters rise, she swims for higher ground: the village school which sits on 20-foot pilings.

Even that isn’t high enough. By the time Warner wakes, she is clinging to the roof of the school, desperate to be saved.

Warner’s vision is not far removed from a reality written by climate change. The people of Newtok, on the west coast of Alaska and about 400 miles south of the Bering Strait that separates the state from Russia, are living a slow-motion disaster that will end, very possibly within the next five years, with the entire village being washed away.

The Ninglick River coils around Newtok on three sides before emptying into the Bering Sea. It has steadily been eating away at the land, carrying off 100ft or more some years, in a process moving at unusual speed because of climate change. Eventually all of the villagers will have to leave, becoming America’s first climate change refugees.
