Every year Vancouver resident Stephen Ottridge takes hamburgers or steak to his street's annual summer block party. This year, against the backdrop of what looks to be the biggest sockeye salmon run in almost a century in the nearby Fraser River, he arrived with a salmon large enough to fill the whole barbecue. "There is a cornucopia of salmon this year, so we decided to treat the block to some," Ottridge said from the city on Canada's Pacific Coast, where marine experts are both puzzled and delighted by the unexpected glut of the bright-red, succulent fish.

There are a lot of things that can go into the ground water. The key is whether what goes in will readily biodegrade and if not can it harm you or the environment. In the first large study to track the fate of a wide range of antibiotics given to dairy cows, University of California (UC) Davis scientists found that the drugs routinely end up on the ground and in manure lagoons, but are mostly broken down before they reach groundwater. Note that antibiotics are given to sick cows who are isolated from the regular milking herd until the antibiotic is absent from their system.

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.

A study of bald eagle nestlings found pesticides and flame retardants in their blood. The chemicals are suspected in slowing the eagles' post-DDT recovery in Michigan. There are lots of new flame retardants in use, the health effects of which we know little or nothing.

An Indonesian volcano, inactive for four centuries, erupted again on Monday, pitching ash two km (1.5 miles) into the air and sending nearby residents scurrying from their homes. Villages were emptying fast near Mount Sinabung on the north of Sumatra island, leaving behind only officials from the bureau of meteorology and the police. Short-haul flights skirting the volcano were delayed. Surono, head of Indonesia's vulcanology center, told Reuters Monday's eruption was more powerful than the first a day earlier. "Earlier today was another eruption at 6.30 a.m., sending out smoke as high as two km, more or less," he told Reuters.

China's decision to slash export quotas of rare earth elements was a necessary step to protect the country's environment, commerce minister Chen Deming said following criticism from Japanese officials. "Mass extraction of rare earth will cause great damage to the environment and that's why China has tightened controls over rare earth production, exploration and trade," Chen was quoted by state news agency Xinhua as saying on Saturday.

Hurricane Danielle weakened to a Category 2 storm on Saturday and was set to pass east of Bermuda by the end of the day, the U.S. National Hurricane Center said. Danielle, located some 340 miles southeast of Bermuda, had top sustained winds of 110 miles per hour, the Miami-based hurricane center said. The hurricane poses no direct threat to land or the U.S. Gulf of Mexico oil patch. A tropical storm watch was in effect for Bermuda but computer models showed Danielle passing well east of the island later on Saturday. The Hurricane Center said dangerous surf conditions would affect Bermuda over the next few days.

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.

Every year an amazing event happens on this small island, owned by Australia, which is 220 miles away from the nearest land mass. Christmas Island's geographic isolation and history of limited human disturbance has brought about a high level of species not found elsewhere in the world. Among these species is the Christmas Island Red Crab. Millions of these crabs simultaneously embark on a five kilometer journey to their ocean breeding grounds. Scientists from the University of Bristol and Bangor University believe they have unlocked the mystery to this incredible feat.

At the onset of the 5th anniversary of Hurricane Katrina, students and emerging professionals are putting their time towards helping to rebuild New Orleans in a sustainable fashion. The 2010 US Green Building Council Natural Talent Design Competition, in partnership with the Salvation Army's EnviRenew program, is preparing to have the final student and emerging professional designs for a small, green and affordable home judged by an internationally recognized panel in conjunction with the citizens of New Orleans' Broadmoor neighborhood (where the homes will be built).

Hurricane Danielle strengthened into a Category 4 storm on Friday as it churned over the Atlantic, the U.S. National Hurricane Center said. Danielle, the first major hurricane of the season, was located some 545 miles southeast of Bermuda and was moving northwest at 12 miles per hour (19 km per hour). It had top sustained winds of 135 mph. Any storm packing winds of at least 111 mph is ranked as "major" by the Miami-based hurricane center. Computer models show Danielle tracking northwest and then in a more northerly direction before passing well east of Bermuda on Saturday night.

The asthenosphere is the highly viscous mechanically weak region of the upper mantle of the Earth on which "float" the continental plates. It lies below the lithosphere, at depths between 60 and 120 miles below the surface, but perhaps extending as deep as 400+ miles. The lithosphere is a complex mixture of layers. For example the North American continent is not one thick, rigid slab, but a layer cake of ancient, 3 billion-year-old rock on top of much newer material probably less than 1 billion years old, according to a new study by seismologists at the University of California, Berkeley.

U.S. government officials urged residents of a Wyoming farming community near natural gas drilling sites not to use private well water for drinking or cooking because of chemical contamination. "Sample results indicate that the presence of petroleum hydrocarbons and other chemical compounds in groundwater represents a drinking water concern," the Environmental Protection Agency said in a statement about tests of 19 water wells around the town of Pavillion. The Wyoming investigation precedes a national study by the EPA into the safety of the drilling technique known as hydraulic fracturing or "fracking", in response to concern in Congress and in some communities near gas rigs in many states that human health is threatened by the process.

The signs are all around. Many places in the world show degradation of the air, water, and soil. Species becoming extinct as natural habitats are being destroyed. The emissions of greenhouse gases that can alter the planet's climate are unacceptable. All the environmental issues put together amount to a very serious threat to human welfare. Yet at the same time, all accepted measures of well-being show that, on average, quality of life is improving around the globe. How does an environmentalist call society into action under such conditions?
