By now I’m sure you know that deforestation is a major source of carbon emissions — in fact more than all the fuel burned for transportation — which would be enough to worry about, except that when it comes to emissions from chopping down trees in the Amazon, those emissions are actually increasing as […]
By Art Chimes, Washington, D.C. Rising levels of carbon dioxide in the atmosphere are a major contributor to climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry, potentially threatening marine life. Montana State University scientist Robert Dore has been taking samples of water in the Pacific […]

By Noreen Parks In addition to weakening Earth’s natural shield against excessive radiation levels, ozone depletion above Antarctica has significantly dampened the Southern Ocean’s ability to absorb atmospheric CO2 and has accelerated acidification of southern polar waters, according to new research reported online June 20 in Geophysical Research Letters (2009, DOI 10.1029/2009GL038227). Of the atmospheric […]
By Michael Perry SYDNEY (Reuters) – Mounting loss of seagrass in the world’s oceans, vital for the survival of endangered marine life, commercial fisheries and the fight against climate change, reveals a major crisis in coastal ecosystems, a report says. A global study of seagrass, which can absorb large amounts of planet-warming carbon dioxide, found […]
Oyster larvae have been dying by the billions. Scientists suspect it’s a sign that carbon dioxide is dramatically affecting the ocean. By Craig Welch, Seattle Times environment reporter WILLAPA BAY, Pacific County — The collapse began rather unspectacularly. In 2005, when most of the millions of Pacific oysters in this tree-lined estuary failed to reproduce, […]
Indonesia’s decision earlier this year to allow conversion of up to 2 million hectares of peatlands for oil palm plantations is “a monumental mistake” for the country’s long-term economic prosperity and sustainability, argues an editorial published in the June issue of Frontiers in Ecology and the Environment. Lian Pin Koh of ETH Zurich, Corey J.A. […]
WASHINGTON, DC, April 21, 2009 (ENS) – Atmospheric concentrations of two of the most potent global warming gases rose last year, according to a preliminary analysis for the annual greenhouse gas index compiled by the U.S. National Oceanic and Atmospheric Administration, NOAA, which tracks data from 60 sites around the world. At the end of […]
Low-oxygen “dead zones” in the ocean could expand significantly over the next century, according to marine chemists. These predictions are based on the fact that, as more and more carbon dioxide dissolves from the atmosphere into the ocean, marine animals will need more oxygen to survive. Concentrations of carbon dioxide are increasing rapidly in the […]
Micro-algae are growing faster under the influence of climate change. However, the composition of the algae is changing, as a result of which their nutritional value for other aquatic life is decreasing. And because algae are at the bottom of the food chain, climate change is exerting an effect on underwater life. This is the […]
