Thursday, December 21, 2017, 12:54 PM - Climate change marched on in 2017. Here are the top stories that shaped the conversation around this critical issue throughout the year.
Record lows in sea ice, cracking glaciers and ice sheets, and enormous new icebergs floating out to sea. Flooding, wildfires, and the heat-death of the Great Barrier Reef. Stories surrounding the impacts of climate change did not pull any punches this year, as they showed not only how bad things are now, but also how much worse they could be in the not-so-distant future. There were also some harder-to-find rays of hope, surrounding the Paris Climate Agreement, and Al Gore's new documentary, An Inconvenient Sequel: Truth to Power.
With 2016 soon to rank as the warmest year on the books, it took its toll on sea ice around the world, leaving global and Arctic extents at their lowest yearly levels ever recorded and with absolutely no help from the Antarctic.
Canada may become something of a safe haven from climate extremes, as a new study says climate change should deliver more mild weather days across much of the country.
Even as the world mobilizes to limit and eventually stop global greenhouse gas emissions, a new study is showing that there is still a high risk of seeing ice-free summers in the Arctic, despite these efforts.
We're in 'uncharted territory' due to the unprecedented global heat Earth is experiencing, sea ice reaches record-breaking lows at both poles, and carbon dioxide levels in the atmosphere may reach 410 ppm this year. It's What's Up In Climate Change!
An immense new crack has formed in Greenland's Petermann glacier, and NASA scientists have now returned the first close-up images of the fissure, which may herald the birth of yet another massive iceberg from the glacier.
The Great Barrier Reef has suffered back-to-back major bleaching events, but is the largest coral reef system in the world truly beyond all hope of saving, as some headlines have recently proclaimed?
There seems to be a lot of confusion going around about carbon dioxide and climate change, so here's how we know that CO2 not only causes climate change, but is the primary driver of the current warming trend of our planet.
A massive iceberg, larger than Prince Edward Island and weighing in at over a trillion metric tonnes, just broke off from Antarctica's Larsen C ice shelf.
Al Gore's
An Inconvenient Sequel: Truth to Power hit theaters, and this was not just another slideshow presentation. This update to
An Inconvenient Truth delivered a powerful message of urgency, and hope, to us all.
The flooding in Texas from Hurricane Harvey and its remnant has reached disastrous levels in some areas, due to a combination of storm surge and days of rainfall. Here's what its effects would look like for Canadian cities.
With more than 12,000 square kilometres scorched across British Columbia, the 2017 wildfire season has been deemed the worst on record, and a University of Alberta scientist says human-induced climate change has made it easier for fires to spread.
Having delivered multiple extreme weather events so far, 2017 is on track to end up - exactly as predicted by climate scientists - in the top three hottest years on record.
Sea levels are rising as our planet warms and glaciers around the world melt in response, and a new NASA tool can tell us exactly which glaciers are responsible for flooding our coastal communities, now and in the future.
Bali's Mount Agung appears to be on the brink of a major eruption, and according to scientists, such an event has the potential to cool the Earth for years to come, and could diminish the impacts of global warming for more than a decade.
