How microbes are cleaning up the BP oil spill

<!– –> Microbes, primarily bacteria and fungi, get a bad rap in today’s society. However they’ve long played an incredible role within the Earth’s ecosystem. And one of the most important places microbes are transforming the earth is in the Gulf of Mexico, where a nu

Wildfires ravage Canada and Alaska causing mass evacuations

“Extreme.” “Unprecedented.” “Historic.” Those are just a few of the words being used to describe the start of this year’s fire season in North America. The wildfires are centered in the northwest of the continent, but their consequences are fa

How human activities have influenced "energy flow" in the environment

A collection of fossilized owl pellets in Utah suggests that when the Earth went through a period of rapid warming about 13,000 years ago, the small mammal community was stable and resilient, even as individual species changed along with the habitat and landscape. By contrast, human-c

As species adapt to a warming climate, ecosystems change

<!– –> If it seems like you’re pulling more bass than trout out of Ontario’s lakes this summer, you probably are. Blame it on the ripple effect of climate change and warming temperatures. Birds migrate earlier, flowers bloom faster, and fish move to newly

Bumblebees trapped in "Climate Vice"

As Europe and North America warm, bumblebees should be able to fly north to cooler climes, writes Tim Radford. But they’re not: the bees’ range is receding in the south, but staying put in the north, and scientists fear their shrinking habitat will put many species at risk

Seabird Populations on the Decline

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

Slight global warming causes six meter sea level rise

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, sc
