NRC: Abrupt Impacts of Climate Change (2013)

Published 3rd December 2013: National Research Council Abrupt Impacts of Climate Change: Anticipating Surprises | Release URL Both abrupt changes in the physical climate system and steady changes in climate that can trigger abrupt changes in other physical, biological, and human systems present possible threats to nature and society. Abrupt change is already underway in some…

Ocean Acidification Summary for Policymakers 2013

Published by IGBP November 14, 2013 This summary for policymakers reports on the state of scientific knowledge on ocean acidification, based on the latest research presented at The Third Symposium on the Ocean in a High-CO2 World, held in Monterey, California, in September 2012. Experts present the projected changes from ocean acidification for ecosystems and the people who rely on…

The Ocean Is Going To Start Confusing Fish And Dissolving Seashells

Climate Progress August 27, 2013: Ocean acidification driven by increasing atmospheric carbon levels is a substantial threat to marine life, a new study has confirmed. The study, published in the journal Nature Climate Change, analyzed 167 studies on the effects of ocean acidification on corals, crustaceans, mollusks, fishes and echinoderms, a group which includes starfish…

Dissolving brittle stars hint at implications of ocean acidification

Image: At the GeoSoilEnviroCARS beamline at the Advanced Photon Source, scientists mapped slices of 24 brittle starfish skeletons in 3 dimensions using X-ray tomography to find out how much volume the eroded skeletons had lost, and to reconstruct their structures.

A Mechanism for Shallow Methane Hydrate Dissociation

I previously looked at the science and commercial usage of Methane Hydrate, at freshwater influx in the Arctic Circle and asked  Does Freshwater Runoff in the Arctic change Ocean Circulation to Unlock Methane Hydrate in the Deep Ocean? This post covers: Identification of possible mechanism which could eventually release vast quantities of shallow Methane Hydrate…

Climate Change Puts Even ‘Safe’ Species at Risk

By Tim Redford, Climate News Network: LONDON—Climate change doesn’t just threaten species that are already vulnerable – it could have alarming consequences for a huge range of birds, corals and amphibians that no-one had considered in danger of extinction before, according to a new study. Wendy Foden of the International Union for the Conservation of…
