UBC research shows world’s monitored seabird populations have dropped 70 per cent since the 1950s, a stark indication that marine ecosystems are not doing well. Michelle Paleczny, a UBC master’s student and researcher with the Sea Around Us project, and co-authors compiled information on more than 500 seabird populations from around the world, representing 19 per cent of the global seabird population. They found overall populations had declined by 69.6 per cent, equivalent to a loss of about 230 million birds in 60 years.

BP has finally agreed to pay for the incredible damage it caused after the headline-grabbing oil disaster in 2010. The company made overtures at responsibility in the past, but this is the farthest BP has gone toward remedying the mess it made during the Deepwater Horizon Oil Spill.
Care2 has been vocal in demanding accountability for the company. A petition garnering over 150,000 signatures was delivered to BP’s offices, but the BP refused to accept the petition.
It seems BP has run out of options and will now be paying billions of dollars in a pending settlement.

A new review analyzing three decades of research on the historic effects of melting polar ice sheets found that global sea levels have risen at least six meters, or about 20 feet, above present levels on multiple occasions over the past three million years. What is most concerning, scientists say, is that amount of melting was caused by an increase of only 1-2 degrees (Celsius) in global mean temperatures.

This turns out to be quite a week for green aviation. First, an incredible milestone in the historic journey of the Solar Impulse as the fuel-free aircraft successfully completed a five-day crossing of the Pacific from Japan to Hawaii, the longest solo manned flight in history. While the realization of commercial solar-powered flight is likely still decades away, this inspirational journey sets a high bar against which all other efforts must ultimately be measured.

While electrical and electronic equipment have never been more efficient, economical or in demand, consumers' desire to own the best and the latest is contributing to an environmental issue of increasing seriousness and concern, according to a new report.
"E-waste is one of the fastest growing waste streams in developing, emerging and developed regions and it covers all electrical and electronic equipment and parts discarded by consumers," says Dr Sunil Herat, Associate Editor of the journal Waste Management & Research and a Senior Lecturer in the School of Engineering at Griffith University in Queensland, Australia.

The U.S. Geological Survey, in collaboration with the U.S. Fish and Wildlife Service, has released a study that will enable ecologists, managers, policy makers, and industry to predict the bird fatalities at a wind facility prior to it being constructed. The study examined golden eagles as a case study because they are susceptible to collisions with wind turbines in part because of their soaring and hunting behavior.

Male badgers that spend their youth fighting tend to age more quickly than their passive counterparts according to new research from the University of Exeter.
The 35-year study revealed that male badgers living alongside a high density of other males grow old more quickly than those living with lower densities of males.

A wide-ranging study of gains and losses of populations of bird species across Mexico in the 20th century shows shifts in temperature due to global climate change are the primary environmental influence on the distributions of bird species. “Of all drivers examined … only temperature change had significant impacts on avifaunal turnover; neither precipitation change nor human impacts on landscapes had significant effects,” wrote the authors of the study, which appeared recently in the peer-reviewed journal Science Advances. Using analytical techniques from the field of biodiversity informatics, researchers compared current distributions with distributions in the middle 20th century for 115 bird species that are found only in Mexico. They then compared those bird community changes to patterns of change in climate and land use.

Mosquitoes that carry the dengue and chikungunya viruses are more widespread than ever, believe scientists mapping the global spread of the insects. There are no treatments or vaccines for these diseases, so knowing where the mosquitoes that transmit them occur and thrive can help focus research and public health resources, the scientists say.
