What Scientists Are Seeing Over Greenland


SpaceRip

Published on Sep 26, 2015

Why are scientists out flying over Greenland, drilling into its ice, and monitoring it from space? The answer is that they see it as a bellwether of future Earth.

Scientists are sampling, drilling, and flying over this great island because they believe it may be a bellwether of future Earth. Greenland is two million square kilometers of land… 81% of which is covered by a giant central ice cap, the Inland Ice. Here is 2.8 million cubic kilometers of ice… layered and packed over the millennia. Its thickest points lie beneath two massive ridges… the northern at 3 kilometers thick, the southern at over 3.2 kilometers.

The Inland Ice basin is framed by parallel mountain ranges. Its bedrock basement floor is down near sea level… depressed by the weight of the ice above it. If this ice sheet were to melt, the land beneath would be underwater, dotted with small islands. Over time, with the weight lifted, it would gradually rise. Today, the sheer mass of the Inland Ice exerts a gravitational pull on surrounding oceans. This pull raises sea levels all around the island.

In the event of extreme melting, a recent study showed that sea levels would actually drop out to a distance of about 1000 kilometers. More distance shores, however, would experience an average global sea level rise of over 7 meters.

An abrupt climate change occurs when the climate system is forced to transition to a new climate state at a rate that is determined by the climate system energy-balance, and which is more rapid than the rate of change of the external forcing. About the book: https://www.amazon.com/gp/product/B00…

Past events include the end of the Carboniferous Rainforest Collapse,[2] Younger Dryas,[3] Dansgaard-Oeschger events, Heinrich events and possibly also the Paleocene-Eocene thermal maximum.[4] The term is also used within the context of global warming to describe sudden climate change that is detectable over the time-scale of a human lifetime. One proposed reason for the observed abrupt climate change is that feedback loops within the climate system both enhance small perturbations and cause a variety of stable states.[5]

Timescales of events described as ‘abrupt’ may vary dramatically. Changes recorded in the climate of Greenland at the end of the Younger Dryas, as measured by ice-cores, imply a sudden warming of +10 °C (+18 °F) within a timescale of a few years.[6] Other abrupt changes are the +4 °C (+7.2 °F) on Greenland 11,270 years ago[7] or the abrupt +6 °C (11 °F) warming 22,000 years ago on Antarctica.[8] By contrast, the Paleocene-Eocene thermal maximum may have initiated anywhere between a few decades and several thousand years. Finally, Earth Systems models project that under ongoing greenhouse gas emissions as early as 2047, the Earth’s near surface temperature could depart from the range of variability in the last 150 years, affecting over 3 billion people and most places of great species diversity on Earth.

The IPCC states that global warming “could lead to some effects that are abrupt or irreversible”.[11]

In an article in Science, Richard Alley et al. said “it is conceivable that human forcing of climate change is increasing the probability of large, abrupt events. Were such an event to recur, the economic and ecological impacts could be large and potentially serious.”[12]

A 2013 report from the U.S. National Research Council called for attention to the abrupt impacts of climate change, stating that even steady, gradual change in the physical climate system can have abrupt impacts elsewhere—in human infrastructure and ecosystems for example—if critical thresholds are crossed. The report emphasizes the need for an early warning system that could help society better anticipate sudden changes and emerging impacts.

Abrupt climate change has likely been the cause of wide ranging and severe effects:

Mass extinctions in the past, most notably the Permian-Triassic Extinction event (often referred to as the great dying) and the Carboniferous Rainforest Collapse, have been suggested as a consequence of abrupt climate change.[2][29][41]
Loss of biodiversity. Without interference from abrupt climate change and other extinction events the biodiversity of this planet would continue to grow.
Rapid Ocean acidification, which can harm marine life (such as corals).

Jayde Lovell sits down with Joseph J. Romm, an American author, blogger, physicist and climate expert, who advocates reducing greenhouse gas emissions and global warming and increasing energy security through energy efficiency, green energy technologies and green transportation technologies.

Romm is a Fellow of the American Association for the Advancement of Science. In 2009, Rolling Stone magazine named Romm to its list of “100 People Who Are Changing America”, and Time magazine named him one of its “Heroes of the Environment”, calling him “The Web’s most influential climate-change blogger”.

U.N. Report Criticizes U.S. Government over Handling of Dakota Access Pipeline

Headlines Mar 06, 2017

And a new United Nations report has criticized the United States government over its handling of the $3.8 billion Dakota Access pipeline, which has faced massive resistance from the Standing Rock Sioux Tribe of North Dakota as well as members of hundreds of other Native American nations. The report says the U.S. government had failed to communicate with and consult Native Americans and showed a “lack of good faith involvement.” The report was delivered to State Department officials Friday. On Saturday, protesters rallied at Columbus Circle in New York City to oppose the pipeline, which is currently in the final stages of construction following the Trump administration’s approval. This is Isha Racho.

Isha Racho: “I think it’s especially meaningful to be at the statue of Christopher Columbus. I was born and raised in New York, and every time I pass it, it just reminds me how much we blatantly love to rub it in the faces of our indigenous people that this land is stolen. But I’m here at the protest because the fight’s not over. A lot of people think it has been finished for weeks or months, but it’s not over, we are still out here, we are still protesting in solidarity, and it is our duty to win, and it is our duty to keep fighting.”

NYT: Trump Admin Has Rolled Back 90 Regulations over Last 6 Weeks

Headlines Mar 06, 2017

The New York Times reports that over the last six weeks the Trump administration has rolled back more than 90 regulations in order to benefit Wall Street banks, gun sellers, coal, oil and gas companies and other corporations. The Times calls the rollback “one of the most significant shifts in regulatory policy in recent decades.” In many cases, the regulatory rollbacks have come after the direct requests of lobbyists or trade industry groups. Trump’s administration is expected to continue eliminating more regulations in the coming days and weeks, including rolling back rules that limit car pollution.
