Creating the Impetus for Climate Action in Ottawa

April’s snow and freezing rain, on top of several months of seemingly erratic weather, is a reminder that climate change is not a future scenario but a current reality.

Last week the federal government released a report, Canada in a Changing Climate. The report gathers the science on the effects of climate change in Canada, and sets out what is expected to happen with and without significant climate action.

One of the report’s main findings: Canada’s climate is warming more than twice as fast as the global average, due to a complexity of factors.

With climate change, we’ll continue to experience increased weather extremes and their effects: hotter temperatures, higher likelihood of high precipitation, flooding, changes to snow and ice cover, and risk of freshwater shortages, to name a few.

The report indicates that the degree to which we will experience these changes depends on how much and how fast we act.

For example, in Ontario, if greenhouse gas emissions are kept relatively low, the number of days over 30 degrees Celsius will increase by four in the latter part of this century. If emissions are high, the number of 30+ degree days is projected to increase by 38. The lower emissions scenario requires “rapid and deep emission reductions.”

Making those reductions requires concerted effort at all levels: individual, local, national and international. It’s daunting, but here’s a place to start:

Everyone is welcome to follow and contribute perspectives to the federal Canada in a Changing Climate initiative.
