EPA Requires 800 million Gallons of Biodiesel in the U.S. Domestic Market in 2011
July 16, 2010 01:18 PM - The Green Economy

WASHINGTON, DC – - Today, the Environmental Protection Agency (EPA) announced it would require the domestic use of 800 million gallons of biodiesel in 2011. This is consistent with the renewable goals established in the Energy Independence and Security Act of 2007 (EISA), which expanded the Renewable Fuels Standard (RFS2) and specifically requires a renewable component in U.S. diesel fuel.

Lakes on Titan
July 15, 2010 04:35 PM - Andy Soos, ENN

Titan, is the largest moon of Saturn, the only natural satellite known to have a dense atmosphere, and the only object other than Earth for which clear evidence of stable bodies of surface liquid has been found. On Earth, lake levels rise and fall with the seasons and with longer term climate changes, as precipitation, evaporation, and runoff add and remove liquid. Now, for the first time, scientists have found compelling evidence for similar lake level changes on Saturn's largest moon showing that is possesses a similar change cycle

US Climate bill sparks opposition from business groups
July 15, 2010 06:35 AM - Timothy Gardner, Reuters

Two U.S. business groups opposed on Wednesday the latest version of a climate change proposal circulating in the U.S. Senate, saying it was unfair to power companies and would hurt energy-intensive industries. Senators John Kerry, a Democrat, and Joe Lieberman, an independent, have crafted a draft bill focusing on capping greenhouse gas pollution from electric power utilities first. It scales back previous ambitions for a broad attack on emissions. The plan would launch a "cap-and-trade" market in which utilities that cut pollution could sell credits to companies that do not. It expects overall emissions limits would be achieved because the cap on all utilities toughens over time.

The Rising Indian Ocean
July 13, 2010 04:33 PM - Andy Soos, ENN

Changing sea levels have happened before and will happen again in a dynamic world. Newly detected rising sea levels in parts of the Indian Ocean, including the coastlines of the Bay of Bengal, the Arabian Sea, Sri Lanka, Sumatra and Java, appear to be at least partly a result of human induced increases of atmospheric greenhouse gases, says a study led by the University of Colorado at Boulder. The study, which combined sea surface measurements going back to the 1960s and satellite observations, will threaten inhabitants of some coastal areas and islands.

June Heat in the US

It is summer and it is traditional to complain about how warm it is. Weather also is always a popular subject. The National Oceanic and Atmospheric Administration (NOAA) State of the Climate report shows the June 2010 average temperature for the contiguous United States was 71.4 degrees F, which is 2.2 degrees F above the long-term average (1901-2000). The average precipitation for June was 3.33 inches, 0.44 inch above the long-term average.

Ten Nations at 'Extreme Risk' Because of Water Shortages, Report Says
July 12, 2010 08:51 AM - Yale Environment 360

Ten countries worldwide, including five African nations, are at "extreme risk" because of limited access to clean, fresh water, according to a new global water security index. And the effects of climate change and population growth will exacerbate the stress on these water supplies, potentially threatening stability in many regions, according to the analysis by Maplecroft , a UK-based consulting group.

Rising sea drives Panama islanders to mainland
July 12, 2010 06:45 AM - Sean Mattson, Reuters

Rising seas from global warming, coming after years of coral reef destruction, are forcing thousands of indigenous Panamanians to leave their ancestral homes on low-lying Caribbean islands. Seasonal winds, storms and high tides combine to submerge the tiny islands, crowded with huts of yellow cane and faded palm fronds, leaving them ankle-deep in emerald water for days on end. Pablo Preciado, leader of the island of Carti Sugdub, remembers that in his childhood floods were rare, brief and barely wetted his toes. "Now it's something else. It's serious," he said.

For Hudson Bay Polar Bears, The End is Already in Sight
July 9, 2010 09:17 AM - Yale Environment 360

The polar bear has long been a symbol of the damage wrought by global warming, but now biologist Andrew Derocher and his colleagues have calculated how long one southerly population can hold out. Their answer? No more than a few decades, as the bears' decline closely tracks that of the Arctic's disappearing sea ice.

Elves and Sprites
July 8, 2010 03:19 PM - Andy Soos, ENN

Upper atmospheric lightning or upper atmospheric discharge are terms sometimes used by researchers to refer to a family of electrical breakdown phenomena that occur well above the altitudes of normal lightning. The preferred current usage is transient luminous events (TLEs) to refer to the various types of electrical discharge phenomena in the upper atmosphere, because they lack several characteristics of the more familiar lower atmospheric lightning. TLEs include red sprites, sprite halos, blue jets, gigantic jets, and elves.

High Above the Earth, Satellites Track Melting Ice
July 8, 2010 08:48 AM - Michael D. Lemonick, Yale Environment 360

The surest sign of a warming Earth is the steady melting of its ice zones, from disappearing sea ice in the Arctic to shrinking glaciers worldwide. Now, scientists are using increasingly sophisticated satellite technology to measure the extent, thickness, and height of ice, assembling an essential picture of a planet in transition.
