Although Canada is home to 20 per cent of the world’s freshwater supply, there are still long-term advisories in effect here for 29 communities that do not have access to clean drinking water. Alarmingly, two-thirds of these long-term advisories affect Indigenous communities, including those in southern Ontario where clean water is plentiful in neighbouring towns and cities. Climate change and extreme events are exacerbating water quality degradation in lakes and rivers. The latest report from the UN’s climate panel highlights the disproportionate impact our warming planet has on marginalized communities. A lack of resilient infrastructure means communities are further affected; prioritizing better connections between water systems and people is essential to achieving equitable and safe access to clean water.
Predicting the unpredictable: How scientists are improving cold-region water and climate prediction models
The world is changing rapidly, and the past is no longer a guide to the future in terms of extreme events and floods. That’s one of the findings from a report on the Changing Cold Regions Network (CCRN), a summary of the research program that wrapped up in 2018 and which recently compiled many of its scientific advances in a special issue of the journal Hydrology and Earth System Sciences.
