U.S. May Remove Humpbacks From List of Endangered Species
September 29, 2009 07:26 AM - R. Greenway, ENN

The U.S. National Marine Fisheries Service may remove the humpback whale from its list of endangered species, citing evidence that the species has rebounded from near extinction. Since an international ban on their whaling in 1966, populations of the north Pacific humpback have increased about 4.7 percent each year, researchers say. An estimated 18,000 to 20,000 humpbacks now exist in the north Pacific.

Scientists discovered 100 plants, 28 fish, 18 reptiles, 14 amphibians, two mammals and one new bird species in the region.

Climate Changes Outpacing Worst-case Projections

Global temperatures may be 4 degrees Celsius hotter by the mid-2050s if current greenhouse gas emissions trends continue, said a study published on Monday. The study, by Britain's Met Office Hadley Center, echoed a U.N. report last week which found that climate changes were outpacing worst-case scenarios forecast in 2007 by the U.N.'s Intergovernmental Panel on Climate Change (IPCC).

Carbon Cycling Processes Of Inland Waters are Important to Understanding Climate Change

In a paper titled "The Boundless Carbon Cycle," published in the September issue of Nature Geoscience, scientists from the University of Vienna, Uppsala University in Sweden, University of Antwerp, and the U.S. based Stroud┢ Water Research Center argue that current international strategies to mitigate manmade carbon emissions and address climate change have overlooked a critical player - inland waters. Streams, rivers, lakes, reservoirs, and wetlands play an important role in the carbon cycle that is unaccounted for in conventional carbon cycling models.

Burning Leaves is Bad News

Remember the smell of burning fall leaves wafting through the air? Good memories, indeed, but best that they remain just memories. Burning leaves is bad news. This practice is now illegal – or at least highly discouraged – in most areas.

Greenhouse Gas Reporting Requirements Finalized
September 25, 2009 07:08 AM - R. Greenway, ENN

A major new regulatory requirement, starting January 1, 2010, will affect most large industrial and utility combustion sources in the US. Fossil fuel and industrial GHG suppliers, motor vehicle and engine manufacturers, and facilities that emit 25,000 metric tons or more of CO2 equivalent per year will be required to report GHG emissions data to EPA annually. This threshold is equivalent to about the annual GHG emissions from 4,600 passenger vehicles.

Thinning Of Greenland And Antarctic Ice
September 24, 2009 06:07 AM - Science Daily

The most comprehensive picture of the rapidly thinning glaciers along the coastline of both the Antarctic and Greenland ice sheets has been created using satellite lasers. The findings are an important step forward in the quest to make more accurate predictions for future sea level rise.

Dust storm blankets Sydney as drought bites

A huge outback dust storm swept eastern Australia and blanketed Sydney on Wednesday, disrupting transport, forcing people indoors and stripping thousands of tonnes of valuable farmland topsoil.

China Pledges to Curb CO2 Emissions

Chinese President Hu Jintao on Tuesday promised to put a "notable" brake on the country's rapidly rising carbon emissions, but dashed hopes he would unveil a hard target to kickstart stalled climate talks. The leader of the world's biggest emitter told a U.N. summit that China would pledge to cut "carbon intensity," or the amount of carbon dioxide produced for each dollar of economic output, over the decade to 2020.

Honey, We're filling that hole in the Ozone Layer!
September 22, 2009 06:39 AM - R. Greenway, ENN

The European Space Agency has presented the results of an important analysis of upper stratospheric ozone, important in shielding Earth from ultraviolet rays. The ozone layer is not distributed evenly, with more changes occurring in the upper stratosphere. By collecting data while looking sideways (limb viewing) rather than vertically downwards, instruments are able to provide highly accurate measurements of the stratosphere. By merging more than a decade of atmospheric data from European satellites, scientists have compiled a homogeneous long-term ozone record that allows them to monitor total ozone trends on a global scale – and the findings look promising.
