By Alister Doyle, Environment Correspondent Wed Aug 11, 2010 12:04pm EDT OSLO (Reuters) – Some of Russia’s smog-causing peatland fires are likely to burn for months, part of a global problem of drained marshes that emit climate-warming greenhouse gases, experts said on Wednesday. Novel carbon markets could offer a long-term fix for peat bogs, from […]
By Richard Galpin6 August 2010 The thick blanket of smog that has shrouded Moscow as peat fires continue to burn just outside the city has worsened. The smog has disrupted air traffic at two international airports in Moscow – Domodedovo and Vnukovo. Many Russians are wearing masks as the temperature rises close to 40C (104F). […]
Provided by American Physiological SocietyAugust 5, 2010 Human impact is causing lower oxygen and higher carbon dioxide levels in coastal water bodies. Increased levels of carbon dioxide cause the water to become more acidic, having dramatic effects on the lifestyles of the wildlife that call these regions home. The problems are expected to worsen if […]
Analysis of air bubbles trapped in an Antarctic ice core extending back 800,000 years documents the Earth’s changing carbon dioxide concentration. Over this long period, natural factors have caused the atmospheric carbon dioxide concentration to vary within a range of about 170 to 300 parts per million (ppm). Temperature-related data make clear that these variations […]
By Craig Welch, Seattle Times environment reporter July 31, 2010 at 8:36 PM DABOB BAY, Hood Canal — Inside the burbling tubs of the Taylor Shellfish hatchery here, oysters are incubating once again. But no one believes things are really back to normal. Several years after oyster larvae around the Northwest began dying by the […]
This figure shows how average temperatures in the lower 48 states have changed since 1901. Surface data come from land-based weather stations, while satellite measurements cover the lower troposphere, which is the lowest level of the Earth’s atmosphere (see diagram on p. 20). “UAH” and “RSS” represent two different methods of analyzing the original satellite […]
Indonesia’s largest palm oil and pulp group, Sinar Mas, is continuing to destroy rainforests and peatland despite promises to end the practice Ecologist29th July, 2010 A major supplier of palm oil and pulp (paper) to multinationals, including food giant Cargill, has been caught clearing orang-utan habitats and carbon-rich peatlands. The Sinar Mas group, which has […]
By Wynne Parry, Senior Writer29 July 2010 07:39 am ET One hundred days ago Thursday, the oil rig Deepwater Horizon began spewing oil into the Gulf of Mexico. As profoundly as the leak of millions of barrels of oil is injuring the Gulf ecosystem, it is only one of many threats to the Earth’s oceans […]
It may takes tens of thousands of years for oceans to recover from the acidity caused by increased levels of carbon dioxide By David Biello July 22, 2010 Single-cell life-forms thrive throughout the world’s oceans—and have for hundreds of millions of years. Tiny varieties known as calcareous nanoplankton build exuberant, microscopic shells—resembling wagon wheels, fishlike […]
Carbon dioxide emissions are making the oceans more acidic, imperiling the growth and reproduction of species from plankton to squid By Marah J. Hardt and Carl Safina “Slow sperm … now that’s a problem,” said Jonathan Havenhand, his British accent compounding the gravity of the message. “That means fewer fertilized eggs, fewer babies and smaller […]
