First UN Environment Assembly Marks Environmental Coming of Age

The UN Environment Programme (UNEP) is taking on a higher profile in multilateral efforts to spur ecosystems-based approaches to governance and development. This includes broad-based, far reaching efforts to craft and implement climate change mitigation and adaptation plans.

Ocean Acidity Rising 10x Faster Than At Any Time in the Past 55 Million Years

Ocean acidification continues to rise at a rate “unprecedented in Earth’s history,” a direct result of past and current increases in carbon and greenhouse gas emissions, posing significant threats to the health and integrity of marine ecosystems and the diverse range of products and services they provide the world over, according to a report produced by the International Geosphere-Biosphere Programme,…

14 Steps to Reduce Black Carbon and Stabilize the Cryosphere

Climate change is causing unprecedented changes in the Earth’s regions of snow and ice, portents of profound, dramatic change for ecosystems and societies around the world, according to a joint report released by The World Bank and The International Cryosphere Climate Initiative (ICCI) November 4. The Earth’s cryosphere is warming more rapidly than anticipated – “at a pace unprecedentd in…

New Research Reveals Climate Warming 55 MYA was Geologically Instantaneous

New research into past changes in climate indicates that global warming can take place much more suddenly than previously thought – over the course of only about 13 years. Temperatures at high latitudes rose as much as 8ºC (14ºF) and oceans warmed from surface to bottom some 55 million years ago during what’s known as the Paleocene-Eocene Thermal Maximum (PETM)….

Warming Ocean Portends Troubling Changes at the Base of the Marine Food Web

Conducting research of potentially vital importance to marine and coastal zone resource policy makers and managers, fisheries managers, fishing communities and stakeholders worldwide, researchers from the University of East Anglia’s (UEA) School of Environmental Sciences and School of Computing Sciences and the University of Exeter have found that warming ocean temperatures pose potentially grave risks to the marine food web….

Analogues from Earth’s Past Bode Ill for Coral Reefs, Marine Ecosystems

In a bid to anticipate the effects of a warming world, climate scientists around the world are scouring the geological record for modern-day analogues – periods of Earth history when the concentration of carbon dioxide (CO2) in the atmosphere reached or exceeded the 400 parts per million (ppm) we find today. Delving into climate, marine biology, ecosystems and the marine…

Are Hawaii's fishermen the scapegoats over environmental problems of which they have no control?

Hawaii’s Fishermen: Scapegoats for Forces Outside their Control

Land use practices and development, along with climate change and other agents, are taking a toll on fisheries in Hawaii and across the Western Pacific, highlighting an increasingly pressing need for policy makers, regulators and other stakeholders to collaborate in crafting holistic, integrated marine resource management and climate change adaptation strategies, local fishermen said at a meeting of the Western Pacific Regional Fishery Management Council.
