On a single hot, dry day this summer, an astonishing 140 wildfires leapt to life across British Columbia. “Friday, July 7 was just crazy,” says Mike Flannigan, director of the wildland fire partnership at the University of Alberta. A state of emergency was declared. By the end of summer, more than 1,000 fires had been triggered across the Canadian province, burning a record nearly 3 million acres of forest—nearly 10 times the average in British Columbia over the last decade. As the fires got bigger and hotter, even aerial attacks became useless. “It’s like spitting on a campfire,” says Flannigan. “It doesn’t do much other than making a pretty picture for the newspapers.”

According to data released Friday by the U.S. Geological Survey and partners, the three-year average of the total counts of southern sea otters was down from last year’s high, although it still exceeded the U.S. Fish and Wildlife Service’s delisting threshold for a second straight year.

In a step toward bridging the gap between fungal taxonomy and molecular ecology, scientists from several institutions including Los Alamos National Laboratory have characterized a sample of “mystery” fungus collected in North Carolina and found its home in the fungal tree of life.

New technological interventions are needed to save coral reefs under climate change.

In a study that shows the importance of climate change on critical pollinators, North Carolina State University researchers found that earlier and longer flowering seasons can have poor effects on the bumble bees that rely on these flowers to live and thrive.

This past summer Canada has been plagued with huge forest fires that have spanned most of the provinces.  British Columbia has been particularly hard hit with large portions of the landscape being decimated by fire.  In these satellite images taken by the NASA'S Aqua satellite, both the natural color and false color burn scars of left by fires can be seen.  In the natural color image it is difficult to make out the burn scars.  The false color easily identifies areas where fire has left a scar showing a brownish-red color. Currently there are 745 wildfires larger than 0.01 hectares and all wildfires of note (active or out) in British Columbia as of today, Sept. 29. (Wildfire link updates daily).  NASA's Aqua satellite collected this natural-color image with the Moderate Resolution Imaging Spectroradiometer, MODIS, instrument on September 27, 2017. 

Tropical forests have long been considered one of the world’s most important tools in combating climate change, their fast-growing trees and rich soils sucking millions of tons of carbon out of the atmosphere every year. But a new study says these forests have switched from being carbon sinks to sources of carbon, releasing an estimated 425 million tons of CO2 each year, more than the annual emissions from U.S. cars and trucks combined.

For the first time since 2011, peak contamination levels in Pacific Canadian waters from Japan’s Fukushima Daiichi nuclear disaster are known, says a University of Victoria scientist who has been monitoring levels since the meltdown of three reactors at the plant.

When a magnitude 9 earthquake shook the western Pacific Ocean floor and sent a tsunami crashing into Japan in 2011, millions of pieces of debris — from docks and fishing boats to plastic pollution — were swept out to sea. Now, a new studyfinds that nearly 300 species hitchhiked aboard that debris across the Pacific and were scattered along the west coast of North America.

Though you might not think of ants as formidable bodyguards, some do an impressive job protecting plants from enemies. Now, scientists at the University of Toronto have determined what makes some better bodyguards than others.

Examining the relationship between the Amazon rainforest plant Cordia nodosa in Peru and the Amazonian ant Allomerus octoarticulatus, they found the degree to which the ants express two genes significantly impacts the amount of protection they provide to their hosts.
