Graph of the Day: Iceland Sea pH, 1985-2008

The graphs show Iceland Sea winter surface water changes in pH, and the saturation state of aragonite. The anthropogenic increase of atmospheric carbon dioxide affects the Nordic Seas both at the surface and at depth. In the surface, the pH has decreased from 8.13 to 8.08 between 1985 and 2008, and the aragonite saturation, which […]

Wheat nutrition declines as CO2 rises

By Nora Schultz You may have thought that the silver lining of rising carbon dioxide levels would be a boost in crop yields. But evidence is mounting that we may trade quantity for quality. The discovery that staple crops like wheat have less protein when grown in high concentrations of CO2 has already caused concern, […]

India soil 'seriously degraded', pollution rising, biodiversity falling, freshwater use unsustainable

At least 45% of Indian land is environmentally “degraded”, air pollution is rising and flora and fauna is diminishing, according to a report. The State of Environment Report is the first to be published for eight years and is the first to use satellite imagery to support its findings. It focuses on water, energy, food, […]

Sub-Arctic timebomb: warming speeds CO2 release from soil

Climate change is speeding up the release of carbon dioxide from frigid peatlands in the sub-Arctic, fuelling a vicious circle of global warming, according to a recently published study. An increase of just 1°C over current average temperatures would more than double the CO2 escaping from the peatlands. Northern peatlands contain one-third of the planet’s […]

Carbon emissions from Amazon deforestation increase as older forest razed

  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 […]

Oceans becoming more acidic, endangering sea life

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 […]

Ozone hole linked to deterioration of Southern Ocean carbon sink

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 […]

Seagrass meadows among the most threatened ecosystems on Earth

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 […]

Acid ocean killing Pacific oyster larvae by the billions

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, […]
