Wiping out species decreases resilience to climate change

24 October 2012 (PhysOrg) – It is tragic whenever any species is lost. Now it appears that the impact of species loss is far-reaching, much more than previously thought. The symbiotic relationships that develop in the environment as a result of high biodiversity make ecosystems more resilient to change. The loss of a species can […]

Graph of the Day: Area of Mid-Summer Bottom Water Hypoxia in the Gulf of Mexico, 1985-2012

Record drought across the United States in 2012 followed a year of record flooding in the Mid-West in 2011, producing two very different areas of hypoxia, or oxygen deficient water, on the Louisiana continental shelf. The 2012 area of low oxygen, commonly known as the ‘Dead Zone,’ measured 7,480 square kilometers (= 2,889 square miles) […]

Gulf of Mexico dead zone smallest ever measured, due to drought in corn belt

By KELLY SLIVKA2 August 2012 In yet another display of the inexorable interdependence of Earth’s ecosystems, a bad summer for Midwestern farmland has turned out to be a good one for life in the Gulf of Mexico. Researchers from the Louisiana Universities Marine Consortium have found that this summer’s hypoxic zone in the Gulf of […]

Guy McPherson: We’re Done

By Guy McPherson22 June 2012 British economist John Maynard Keynes (1883-1946) is well known for his views on monetary policy.

Web of marine life disintegrating under human onslaught

NEW YORK, New York, 22 May 2012 (ENS) – Oceans cover about 72 percent of Earth’s surface area and there are an estimated 250,000 marine species. “Yet, despite its importance, marine biodiversity has not fared well at human hands,” UN Secretary-General Ban Ki-moon said today in his message to mark the International Day for Biological […]

Climate change could reduce economic value of oceans by $2 trillion per year

21 March 2012 (SEI) – A global, integrated approach is urgently needed to protect the oceans from converging threats. A new study coordinated by SEI shows climate change alone could reduce the economic value of key ocean services by up to 2 trillion USD a year by 2100, and urges world leaders to make the […]

Water pollution rises from farms, costing billions

By Tara Patel13 March 2012 Water pollution from agriculture is costing billions of dollars a year in developed countries and is expected to increase in China and India as farmers race to increase food production, the Organization for Economic Cooperation and Development said. “Pollution from farm pesticides and fertilizers is often diffuse, making it hard […]
