Are Aluminum Bottles Greener than Glass?
July 18, 2009 11:33 AM - , Triple Pundit

Aluminum as a substitute for glass bottles has been inching its way into the consumer experience in the last few years, most notably in the US in the form of beer bottles from Anheuser-Busch and Iron City Beer, a popular regional brand founded in Pittsburgh. Coca-cola has also announced plans to roll out aluminum bottles in this country, though only in limited venues.

Sun's Activity Cycle Linked to Earth Climate
July 18, 2009 10:01 AM - LiveScience

When the sun's weather is most active, it can impact Earth’s climate in a way that is similar to El Niño and La Niña events, a new study suggests. The sun experiences a roughly 11-year cycle, during which the activities on its roiling surface intensify and then dissipate. (One noted sign of a highly active period is the number of sunspots dotting the solar surface). The total energy reaching Earth from the sun varies by only 0.1 percent across the solar cycle.

Are the deserts getting green?

It has been assumed that global warming would cause an expansion of the world's deserts, but now some scientists are predicting a contrary scenario in which water and life slowly reclaim these arid places. They think vast, dry regions like the Sahara might soon begin shrinking.

Exxon Plan to develop biofuel from algae

Exxon Mobil Corp will invest $600 million over the next five to six years on trying to developing biofuel from algae, even though the oil major has said renewables will be only a small part of global energy supply. Exxon, placing its largest financial bet on renewable fuels, is forming a research and development alliance with Synthetic Genomics Inc, a privately held company that focuses on gene-based research, the company said on Tuesday.

Global Warming: Scientists' Best Predictions May Be Wrong

July 15, 2009 08:05 AM - Canada.com from Agence France-Presse

A runaway spurt of global warming 55 million years ago turned Earth into a hothouse but how this happened remains worryingly unclear, scientists said on Monday. Previous research into this period, called the Palaeocene-Eocene Thermal Maximum, or PETM, estimates the planet's surface temperature blasted upwards by between five and nine degrees Celsius in just a few thousand years.

Electric cars could charge to dominance in U.S.
July 13, 2009 08:32 AM - Reuters

Electric car sales could jump to 86 percent of U.S. light vehicle sales in 2030 if consumers don't have to buy batteries themselves, according to a University of California, Berkeley study to be released on Monday. A company called Better Place and emerging rivals plan to offer pay-per-mile plans, similar to cell phone minutes.

Declining Aral Sea: Satellite Images Highlight Dramatic Retreat
July 12, 2009 07:03 AM - Editor ENN, adapted from materials from the European Space Agency

Envisat images highlight the dramatic retreat of the Aral Sea’s shoreline from 2006 to 2009. The Aral Sea was once the world’s fourth-largest inland body of water, but it has been steadily shrinking over the past 50 years since the rivers that fed it were diverted for irrigation projects. By the end of the 1980s, it had split into the Small Aral Sea (north), located in Kazakhstan, and the horse-shoe shaped Large Aral Sea (south), shared by Kazakhstan and Uzbekistan.
