A crisis is looming for Canadian climate research on scientific issues of critical relevance to Canadians, as The Globe reported in June.

With anthropogenic emissions of greenhouse gases driving rapid global warming, Arctic sea ice loss and permafrost retreat, climate change is set to affect Canadians in myriad ways. But to understand just how much change Canadians are going to see, and how we can best adapt to these changes, up-to-date scientific research and information are urgently needed.

For the past five years, seven national climate research networks supported by the Government of Canada's Climate Change and Atmospheric Research (CCAR) program have been investigating questions that impact the daily lives of Canadians. This includes research ranging from the role of greenhouse gases and aerosol particles in recent Arctic sea ice loss, the Alberta floods of 2013 and the Fort McMurray wildfire of 2016; the state and fate of the Arctic's ocean, clouds, air quality, permafrost and glaciers in an era of rapid global warming; how the Labrador Sea "breathes," storing carbon dioxide and thus decreasing its rate of increase in the atmosphere; to changes in cold climate soils and snow and how this will impact water resources. Unfortunately, funding for these programs is set to expire within the year.

This critical research better positions Canadians to understand how their landscapes will change due to climate change; enables environmental policy and business decisions based on sound, scientific evidence; and drives improved marine and climate prediction systems that provide climatic forecasts seasons to years ahead.

At a modest investment of about $7-million per year, these funds have trained over 350 highly qualified personnel (undergraduate students, graduate students and other trainees) and supported field research across Canada. It's also fostered impressive partnerships between Canadian universities and government laboratory researchers to leverage breakthroughs that would not have been possible otherwise. An interim evaluation of CCAR suggests that, to date, the program has operated effectively and has enhanced research on climate change and atmospheric processes, thus advancing Canada's scientific and environmental interests.

It was therefore surprising and disheartening to learn that the 2017 federal budget did not include a renewal of the CCAR program. As a result, these science networks will have to terminate personnel and science positions, cancel training opportunities, shut down field programs and limit Canada's participation in international programs that are looking at global aspects of climate change. Even if funding does come along eventually, Canadian climate science is now facing another gap that will bring about irreversible disruption to the research capacity built over the last five years.

We are encouraged by the Canadian public's growing acceptance of the scientific evidence for global climate change and its importance for our everyday lives, as well as Canada's commitments to the Paris climate-change agreement.

We recognize the need to move toward climate change solutions within the pan-Canadian framework on clean growth and climate change – whether those involve green technology and design, measures to generate climate resilient infrastructure and/or transitioning to a low-carbon economy.

While our scientific understanding is advancing, our climate is still changing and we must figure out the causes and impacts of those changes – this is imperative. Canada needs continued investment in climate research to stay up-to-date with these advances, to lead the market with new technologies, new observations, framework commitments that require accounting for greenhouse gas emissions and sudden environmental changes that will impact us.

This is the second time in recent memory that climate research funding in Canada has been under threat. The previous government cut funding in 2009 to programs before reinstating support under CCAR in 2013. Now, with the current government not renewing CCAR funding, there are currently no meaningful climate research programs in Canada at a national scale, and no vision to drive progress in this important research area.

The federal government has prioritized action on climate change and has committed to policies that are based on well-supported science. Effective action and commitment will be impossible unless Canadians and decision-makers have up-to-date information on how our climate is changing. The government needs to follow through on its commitment with a continued emphasis on climate research funded through an open peer-reviewed process that would invite creative ideas that serve well-defined scientific and practical objectives. Canadian researchers stepped up to this challenge in the past through the CCAR program and this resulted in world-class research in this critical area.

For our future's sake, we need to continue this effort and not allow climate research to fall through another funding gap.

Justin Trudeau marked World Environment Day Monday with a paddle on the Niagara River and a plea for climate action. The prime minister said Canada 'won’t walk away' from global efforts to stop climate change.
