Canada’s Changing Climate Report
April 07, 2019
Canadians are experiencing the costs of climate-related extremes first hand, from devastating wildfires and flooding to heatwaves and droughts. As the planet warms, extreme weather events will become increasingly common. The knowledge provided by our scientists has helped us understand that climate change is real and driven by human activity. The Government of Canada will continue to work with Canadian scientists, by listening to their expertise and evidence-based advice to help us continue to take ambitious action to reduce emissions and fight climate change.
Just released, Canada’s Changing Climate Report provides the first in-depth, stand-alone assessment of how and why Canada’s climate has changed, and what changes are projected for the future. Undertaken by some of Canada’s finest scientists, this report provides an independent analysis and evaluation of the scientific confidence based on the scientists’ expert judgement. The assessment was led by Environment and Climate Change Canada, with contributions from Fisheries and Ocean Canada, Natural Resources Canada and university experts.
The assessment confirms that Canada’s climate has warmed in response to global emissions of carbon dioxide from human activity. The effects of widespread warming are already evident in many parts of Canada and are projected to intensify in the near future. A warmer climate will affect the frequency and intensity of forest fires, the extent and duration of snow and ice cover, precipitation, permafrost temperatures, and other extremes of weather and climate, as well as freshwater availability, rising of sea level, and other properties of the oceans surrounding Canada.
This is the first report completed as part of the National Assessment Canada in a Changing Climate: Advancing our Knowledge for Action, led by Natural Resources Canada. It provides the climate science foundation for the forthcoming reports by addressing the impacts of climate change on our communities, environment, and economy, as well as how we are adapting to reduce risk.
This report may be a bit of a stretch for our students. On the other hand, they probably know more about the climate than most adults (having just studied it) and the language isn't much harder than a senior textbook. The information is fresh — and certainly relevant to them.

Discovery: Donna Strickland and extremely powerful lasers
April 06, 2019
Discovery is a BBC Radio 4 programme that explores today's most significant scientific discoveries and talks to the scientists behind them.
Donna Strickland tells Jim Al-Khalili why she wanted to work with lasers and what it feels like to be the first woman to win a Nobel Prize for Physics in 55 years. When the first laser was built in 1960, it was an invention looking for an application. Science fiction found uses for these phenomenally powerful beams of light long before real world applications were developed. Think Star Wars light sabres and people being sliced in half. Today lasers are used for everything from hair removal to state of the art weapons. Working with her supervisor Gerard Mourou in the 1980s, the Canadian physicist, Donna Strickland found a way to make laser pulses that were thousands of times more powerful than anything that had been made before. These rapid bursts of intense light energy have revolutionised laser eye surgery and, it's hoped, could open the doors to an exciting range of new applications from pushing old satellites out of earth's orbit to treatments for deep brain tumours.
