September 7, 2010 08:58 AM - Science Daily

ScienceDaily (Sep. 3, 2010) — ESA's (European Space Agency) Envisat satellite has been tracking the progression of the giant iceberg that calved from Greenland's Petermann glacier on 4 August 2010. A new animation shows that the iceberg, the largest in the northern hemisphere, is now entering Nares Strait -- a stretch of water that connects the Lincoln Sea and Arctic Ocean with Baffin Bay.

The United States reiterated on Friday that it was committed to cutting greenhouse gas emissions by 2020 even though the Senate has failed to pass legislation. "I am in no sense writing off legislation over time. And I'm quite sure the president isn't," U.S. climate envoy Todd Stern told a news conference during two days of talks in Geneva among about 45 nations reviewing climate finance.

Hurricane Earl
September 2, 2010 05:10 PM - Andy Soos, ENN

Hurricane Earl is still a powerful category four hurricane on the Saffir-Simpson Scale as it approaches the North Carolina coast September 2. NASA's Tropical Rainfall Measuring Mission satellite observed the high rates rain was falling within Earl in some areas more than 2 inches per hour. Hurricane Earl became the most powerful hurricane of the 2010 Atlantic season early on September 2 when its sustained winds reached 120 kts (~138 mph). It was still intensifying when the TRMM satellite passed near its location on 2 September 2010. The TRMM Microwave Imager data were used in the rainfall analysis that showed heavy rainfall, particularly in the northwest quadrant of Earl's very distinct circular eye.

Top Climate Skeptic Reverses Course, Now Urges Bold Action

Bjørn Lomborg may not be a household name around here, but that's through no fault of his. In November 2001, this Danish environmental author and economics professor was selected "Global Leader for Tomorrow" by the World Economic Forum. Controversy may as well have been his middle name, especially after his book The Skeptical Environmentalist: Measuring the Real State of the World came out in 2001. However, Lomborg has a new book entitled Smart Solutions to Climate Change: Comparing Costs and Benefits in which he proposes an aggressive $100 billion annual fund specifically targeting global warming solutions...

Indonesian Volcanos
September 1, 2010 04:38 PM - Andy Soos, ENN

The geography of Indonesia is dominated by volcanoes that are formed due to subduction zones between the Eurasian plate and the Indo-Australian plate. Some of the volcanoes are notable for their eruptions, for instance, Krakatau for its global effects in 1883, Lake Toba for its supervolcanic eruption estimated to have occurred 74,000 Before Present which was responsible for several years of cold of volcanic winter, and Mount Tambora for the most violent eruption in recorded history in 1815. Indonesia's Mount Sinabung has recently erupted, two days after it sprang back into life after over 400 years of inactivity.

Study: Horseshoe Crab Decline Connected to Climate Change
August 31, 2010 10:56 AM - David A Gabel, ENN

The horseshoe crab is one of the most ancient animals on the planet today. They have survived massive upheavals throughout the Earth's history and have remained intact and unchanged. Recently their numbers have been in decline, and this is thought to be due to coastal habitat destruction and over-harvesting; they are often used as bait, in fertilizer, or by pharmaceutical companies. However, new research from the US Geological Survey (USGS) indicates that their population size also parallels changes in the climate. With predicted climate change in the future, their numbers may continue to decline.

A History of Destruction: 8 Great Hurricanes

From June 1 through Nov. 30 each year, the coastal United States comes under threat from the ferocious winds and floodwaters of the hurricanes that form in the Atlantic Ocean basin. While Katrina is the most remembered of these swirling storms — its name now infamous — it certainly isn't alone in causing significant death and destruction to areas of the United States. Following are eight of the most destructive storms in recorded U.S. history from 1900 until present day.

New Findings on Carbon Dioxide Release from World's Oceans
August 30, 2010 10:16 AM - David A Gabel, ENN

Carbon Dioxide (CO2), a greenhouse gas, is intricately linked to global warming. The largest store of CO2 is the world's oceans. How the oceans sequester or release CO2 to or from the atmosphere is important to understand as mankind alters Earth's climate with the burning of fossil fuels. A new report from researchers at the University of California, Davis offers clues on how that mechanism works by analyzing the shells of plankton fossils.

Solar Storm
August 27, 2010 11:36 AM - Andy Soos, ENN

A geomagnetic storm (or solar storm) is a temporary disturbance of the Earth's magnetosphere caused by a massive solar flares or related sun output. A geomagnetic storm is caused by a solar wind shock wave which typically strikes the Earth's magnetic field 3 days after the event on the sun. The effect on the earth can be small or it can be large. Astronomers are predicting that a massive solar storm, much bigger in potential than the one that caused spectacular light shows on Earth earlier this month, will strike our planet in 2012 with a force of 100 million hydrogen bombs. This is far larger than average.
