In today’s economy, energy efficiency is a top priority for both public and private institutions. It promises to reduce energy expenditures, lower GHG emissions, and – of course! – to save a pile of money. So, does this mean that we can finally save money from energy efficiency – without having to spend more cash first?

The US ranks next to last among G8 member countries when it comes to cutting greenhouse gas emissions and paving the way toward a clean energy economy, according to a World Wildlife Fund SE-Allianz study released July 1.

Scientists from Texas are batty over a new discovery which could lead to the single most important medical breakthrough in human history—significantly longer lifespans.

The rain band near the equator that determines the supply of freshwater to nearly a billion people throughout the tropics and subtropics has been creeping north for more than 300 years, probably because of a warmer world, according to research published in the July issue of Nature Geoscience. If the band continues to migrate at just less than a mile (1.4 kilometers) a year, which is the average for all the years it has been moving north, then some Pacific islands near the equator -- even those that currently enjoy abundant rainfall -- may be drier within decades and starved of freshwater by midcentury or sooner. The prospect of additional warming because of greenhouse gases means that situation could happen even sooner.

To many of us it seems as though the climate change debate is only a recent phenomena, and indeed, we have been positively bombarded by the media coverage of global warming in the past decade. Surprisingly, though, climate change speculation and study have been taking place for quite some time. In his recently published article in Weatherwise, a non-profit weather magazine, professor of geological sciences and contributing editor Randy Cerveny points out that some unexpected characters were just as concerned with weather change as we are now. Any self- respecting history buff might guess that the foremost of our founding fathers to study climate change would have been Benjamin Franklin. It all adds up—he discovered electricity, invented bifocals, and constructed the first lightning rod. However, although Franklin was an outspoken student of weather and nature, Cerveny classifies none other than Noah Webster, lexicographer and founder of the modern Merriam- Webster Dictionary, as “one of the most strident investigators on the subject of early American climate change.”

The US Environmental Protection Agency today announced the next steps in a coordinated strategy to reduce emissions from ocean-going vessels. EPA is proposing a rule under the Clean Air Act that sets tough engine and fuel standards for U.S. flagged ships that would harmonize with international standards and lead to significant air quality improvements throughout the country. "These emissions are contributing to health, environmental and economic challenges for port communities and others that are miles inland. Building on our work to form an international agreement earlier this year, we’re taking the next steps to reduce significant amounts of harmful pollution from getting into the air we breathe," said EPA Administrator Lisa P. Jackson. "Lowering emissions from American ships will help safeguard our port communities, and demonstrate American leadership in protecting our health and the environment around the globe."
