Rocky Mountain glaciers could be 90% gone by 2100!

According to a new study by UBC researchers, B.C. and Alberta’s glaciers will probably disappear very quickly over the next few decades and could be 70% gone by the end of the century. This calculation includes coastal B.C.’s mountains, which are  expected to lose half their ice during this time, and our Rocky Mountains, with a devastation 90% ice cover loss

Some hopeful stories for your winter blues.

It would be an understatement to say I dislike winter - the grey skies, incessant snow shoveling and the unusually cold weather we've faced this year has me longing for April already. How about some good news? We've spent the holiday season inundated with stories of rampant consumerism, wasteful spending and general doom-and-gloom prophecies for the environment - I know I could use some mid-winter cheer!

There’s a new greenhouse gas on Earth, and it's the worst one yet.

When we talk about the ability of greenhouse gases (GHGs) to warm the Earth’s climate, we often categorize these substances by their ‘effectiveness’, or the warming potential of one molecule of one compound.  (Explaining why a ‘good’ GHG is actually ‘bad’ for our planet).  We all know that the quantity of carbon dioxide in our atmosphere is concerning (over 400 parts per million), but other GHGs are actually more effective than CO2.  Methane, for instance, is anywhere from 20 to 30 times more effective a GHG than carbon dioxide (though this figure is highly debatable), explaining why release of methane from northern permafrost melt as the result of a warming climate is such a high priority concern.

Our Temperamental Planet: Reading Between the Lines with the IPCC.

The news from the latest Intergovernmental Panel on Climate Change (IPCC) report is as unsurprising as it is worrisome: Through our general human nature to make things we like and have a rip-roaring good time, we have mistreated our partner in existence, the Earth. What we see as an afternoon of excitement, tearing around the desert in a dune-buggy, the Earth takes as a slap in the face. Like any mistreated member of a partnership, the Earth has a breaking point and it is starting to get a little peeved.

332 Reasons to Care About Rising Global Temperatures

If you’re like me, you have parents or extended family that like to drift down memory lane to tell you one of their ‘classic’ stories; it usually starts with a “Back in my day”, followed by an exaggerated tale of a high school fling, or something embarrassing about them that you would quite like to erase from your memory. When it comes to our climate, however, it seems our older family members have one story that most from our generation cannot tell, and perhaps we should care to listen. The fact is if you’re 27 years old or younger, you have never lived through a month where average global temperatures have been colder than the 20th century average of 15.5 degrees Celsius (measured from 1901-2000). On the contrary, the end of October 2012 marked the 332nd consecutive warmer-than-average global temperature month.

Climate Change: The Impact on Marine Ecosystems.

Marine ecosystems are particularily affected by climate change because of the effects of warming water, increasing acidification, and lowering oxygen levels. It is difficult to monitor some marine animals due to their unseen habitat or their sizes. This causes many food chains to be threatened, life cycles and migrations routes to be altered, and helps increase habitat suitable for invasive species.
