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.

Nitrogen can present a dilemma for farmers and land managers.

Latest satellite images reveal a new 100-square-mile iceberg emerging from Antarctica’s Pine Island Glacier. The calving event did not come as a complete surprise, but is a troubling sign with regards to future sea level rise.

Certain marine species will fare much worse than others as they become more vulnerable to the effects of climate change, a new UBC study has found.

Researchers have found that three common species of Vibrio bacteria in Chesapeake Bay could increase with changing climate conditions by the end of this century, resulting in significant economic and healthcare costs from illnesses caused by exposure to contaminated water and consumption of contaminated shellfish.

Unusually warm ocean conditions off the Pacific Northwest in the last few years led anchovies, sardines and hake to begin spawning in Northwest waters much earlier in the year and, for anchovy, longer than biologists have ever recorded before, new research has found.
