In Canada’s Arctic, where communities are experiencing the effects of a changing climate, there’s a rising sense of urgency. So — as fluctuating water levels start to impact daily life in the Mackenzie Delta region — a unique partnership was created to investigate further.

What, exactly, would happen if an earthquake occurred in your area? A team at Natural Resources Canada have some answers. They’ve crunched the data for a new, online planning tool — RiskProfiler — that provides a risk analysis of the damages, injuries and financial costs that might result from an earthquake. The consequences could be quite staggering.

Imagine trying to measure something that’s invisible when conditions are changing every day. Yet keeping track of greenhouse gas emissions is increasingly important in our rapidly changing world. Discover how Natural Resources Canada’s highly skilled carbon accounting team calculates these complex estimates for all of Canada’s forests.

From 1952 to 1993, one of the world's largest aerial pesticide application programs occurred in New Brunswick. During this time, 97 percent of the province's 6.2 million hectares of forested land was treated with at least one pesticide. A team of researchers and scientists have now compiled and published historical records of pesticide use. The goal is to make the data available to help future studies on the environmental fate — which is what happens to a pesticide once it enters the environment — as well as ecosystem recovery and the legacy effects of this historical program.

Did you know that Canada is home to the oldest rock ever discovered? It’s the 4.03-billion-year-old Acasta gneiss. For most of us, four billion years is an unimaginable length of time. So how do we know this rock is in fact almost as old as Earth itself? Simply Science visits a highly specialized Geological Survey of Canada lab in Ottawa to meet a team of time-travelling rock star experts who figure this all out.
