The discovery of the Oceanic Anoxic Events (H.Jenkyns) Published on Jan 17, 2015 by Mini Geology. Hugh Jenkyns goes through the contingent facts that made him discover that the earth underwent peridos of global anoxia. Then he links it with present Climate Change. Hugh has established the global synchroneity of black-shale development in intervals in the Mesozoic, he has been editor of GEOLOGY and has received the Sloss Award from the Geological Society of America Read more about Hugh at: www.geosociety.org/awards/10sp...

Biogeochemical regulation: Anoxia in the Past and Present (September 2016) Published on Jan 6, 2017 by Climate State September 2016: Professor Andrew Watson FRS, (University of Exeter, UK) speaks at Royal Society event Ocean ventilation and deoxygenation in a warming world. Abstract The major biogeochemical cycles which keep the present-day Earth habitable are linked by a network of feedbacks which has led to a broadly stable chemical composition of the oceans and atmosphere over hundreds of millions of years. This includes the processes which control both the atmospheric and oceanic concentrations of oxygen. However, one notable exception to the generally well-behaved dynamics of this system is the propensity for episodes of ocean anoxia to occur and to persist for 105 – 106 years, these OAEs (Ocean Anoxic Events) being particularly associated with warm “greenhouse” climates. OAEs are, we believe, amplified by positive feedbacks on the nutrient content of the ocean: low oxygen promotes the release of phosphorus from ocean sediments, which increases ocean productivity and drives more anoxia in the subsurface water, leading to a potentially self-sustaining condition of deoxygenation. The rapidly increasing degree of ocean deoxygenation occurring today as a result of the warming climate could conceivably result in such a very long-lasting and unpleasant consequence for the Earth’s biogeochemical cycles which underpin the “life support” system of the biosphere. royalsociety.org/science-even...

Kiribati: a drowning paradise in the South Pacific | DW Documentary DW Documentary Published on Nov 8, 2017 by DW Documentary. Climate change and rising sea levels mean the island nation of Kiribati in the South Pacific is at risk of disappearing into the sea. But the island’s inhabitants aren’t giving up. They are doing what they can to save their island from inundation. Can COP23 help make a difference? UN estimates indicate that Kiribati could disappear in just 30 or 40 years. That’s because the average elevation is less than two meters above sea level. And some of the knock-on effects of climate change have made the situation more difficult. Kiribati can hardly be surpassed in terms of charm and natural beauty. There are 33 atolls and one reef island – spread out over an area of 3.5 million square kilometers. All have white, sandy beaches and blue lagoons. Kiribati is the world’s largest state that consists exclusively of atolls. A local resident named Kaboua points to the empty, barren land around him and says, "There used to be a large village here with 70 families." But these days, this land is only accessible at low tide. At high tide, it's all under water. Kaboua says that sea levels are rising all the time, and swallowing up the land. That’s why many people here build walls made of stone and driftwood, or sand or rubbish. But these barriers won't stand up to the increasing number of storm surges. Others are trying to protect against coastal erosion by planting mangrove shrubs or small trees. But another local resident, Vasiti Tebamare, remains optimistic. She works for KiriCAN, an environmental organization. Vasiti says: "The industrialized countries -- the United States, China, and Europe -- use fossil fuels for their own ends. But what about us?" Kiribati's government has even bought land on an island in Fiji, so it can evacuate its people in an emergency. But Vasiti and most of the other residents don't want to leave. _______ Exciting, powerful and informative – DW Documentary is always close to current affairs and international events.

Saving Paradise: Sea Level Rise, Changing Cape Cod's Groundwater Published on Feb 17, 2015 by Association to Preserve Cape Cod Sea level rise is threatening Cape Cod's coastline, but the impacts are not always visible. Funded by the Massachusetts Environmental Trust, the Association to Preserve Cape Cod teamed up with the US Geological Survey and the Cape Cod Commission to map and model how rising seas are causing groundwater to rise under our feet. As USGS Hydrologist Peter Weiskel puts it, this could be called "an inundation from below" study. Bob Oldale, a homeowner in New Silver Beach, North Falmouth, explains what happened to his neighborhood when groundwater level became too high after Hurricane Bob: three septic systems and a sewer installation later, he warns that we need to adapt to ever-changing water levels, before it's too late. Bob's story is rounded out by comments from George Heufelder, the director of the Barnstable County Department of Health and the Environment, on the public health risk of septic systems and sewer lines that are too close to groundwater. Laurel Schaider, a research scientist with the Silent Spring Institute, talks about her study of pharmaceuticals and other unregulated contaminants in wastewater, and how they're getting from septic systems and into drinking water. APCC Director Ed DeWitt, follows up with a call to action: we need to stem the rising tides by reducing our carbon footprint, and mitigating its inevitable effects of sea level rise by protecting our vulnerable coastline. m.youtube.com/watch?v=enCVANaFMOA |

Honolulu and Waikiki: Sea Level Rise - Groundwater Inundation Published on Mar 26, 2017 by University of Hawai‘i News New research from the University of Hawaiʻi at Mānoa reveals a large part of the the heavily urbanized area of Honolulu and Waikīkī is at risk of groundwater inundation—flooding that occurs as groundwater is lifted above the ground surface due to sea level rise.
