“I don’t expect people to be worried about more cyclotella, or to be scared of it. What happens (in the food chain) above that may be the problem.”
November 22, 2016 – Dr. Dianne Saxe, Environmental Commissioner of Ontario, today released her 2016 Greenhouse Gas Progress Report, Facing Climate Change. The report reviews the impacts of climate change, and why Ontario must dramatically reduce its greenhouse gas emissions. It also includes information on Ontario’s current emissions, and what the government is doing to reduce them.
November 21, 2016 – FloodSmartCanada is a project created by Partners for Action (P4A), providing a hub of information related to floods, flood risks, and emergency preparedness. This information is intended to educate community members, organizations, businesses and municipalities about floods and to share information.
Most Canadians don’t realize they are at risk, and don’t have a plan to protect themselves from flood. Even if you don’t live near water, your home or business could be at risk, and preparing now could save you money later. FOCA is a member of the Stakeholder Group of the Partners for Action (P4A).
November 12, 2016 – In a report entitled Unbreakable: Building the Resilience of the Poor in the Face of Natural Disasters published this week by the World Bank and the Global Facility for Disaster Reduction and Recovery (GFDRR), World Bank Group president, Jim Yong Kim, said “Building resilience to disasters not only makes economic sense, it is a moral imperative.” The report assesses the benefits resilience-building interventions can have, including access to adequate types of insurance, early warning systems and other measures.
August 29, 2016 – Waterfront Ontario may be at relatively less dire risk from a changing climate/water future than portrayed in the World Bank’s new publication, High and Dry: Climate Change, Water, and the Economy, yet building resilience can help our communities to limit the negative impacts.

August 2016 – State of the Climate report confirms 2015 was Earth’s warmest year on record (American Meteorological Society)
May 18, 2016 – Today, Ontario passed the Climate Change Mitigation and Low-Carbon Economy Act, as it moves towards joining the biggest carbon market in North America. According to today’s press release, the province will be accountable for investing proceeds from the cap and trade program into actions that reduce greenhouse gas pollution, create jobs and help people and businesses shift to a low-carbon economy.
Ontario’s Climate Change Strategy states that:
Climate change requires a shift in thinking and behaviour. There are costs to inaction and there are risks if we don’t plan ahead in areas such as public safety and emergency response, roads and other infrastructure, buildings and homes. Adapting and managing risk must be considered side-by-side with reducing greenhouse gas emissions as Ontario plans and invests for the future.
Some perspective from FOCA:
Our climate is changing, in large part from human causes. Climate change will affect our land and water resources, our economy and ultimately our way of life; these profound impacts have obvious policy implications, and will affect our communities and all of us as individuals.
Our job as lake managers has gotten more challenging.
All of the lake and watershed protection and management activities that FOCA advocates for will become more critical and important as a result of the impacts of climate change. As stated in the 2011 OMNR Summary report by Dove-Thompson et al.:
“Given the importance of understanding the range of potential climate change effects on aquatic assets, it is essential that management agencies and organizations identify and apply appropriate effective mitigation and adaptive management strategies.”
Flood Happens. How can our communities weather the storm?
FOCA has joined the University of Waterloo’s “Partners for Action” (P4A) initiative. P4A is facilitating collaboration between researchers, government, and non-governmental organizations towards making strategic decisions to improve flood resiliency in our communities.
May 18, 2016 – According to the US National Oceanic and Atmospheric Administration, “The globally averaged temperature over land and ocean surfaces for April 2016 was the highest for the month of April in the NOAA global temperature dataset record, which dates back to 1880. This marks the 12th consecutive month that the monthly global temperature record has been broken, the longest such streak in the 137-year record.”
The combined average temperature over global land and ocean surfaces for April was 1.98 Fahrenheit (1.10 Celsius) above the 20th century average of 56.7 F (13.7 C). See more climate information from NOAA

December 17 – Canadian lakes and those that are ice-covered in winter are warming twice as fast as others (CBC News)
December 16, 2015 – Lakes are warming
A recently published study analyzed 25 years of data worldwide and concludes that there is pervasive and rapid warming in freshwater lakes at rates much greater than the warming rate of either the ocean or the atmosphere. The study notes that lakes hold a large majority of Earth’s liquid freshwater, support enormous biodiversity, and provide key provisioning and cultural ecosystem services to people around the world. In the Great Lakes region (and in Northern Europe), lakes were warming significantly faster than the global average.
Since even seemingly small changes in lake temperature can profoundly affect key physical and biological processes, climate change is among the greatest threats to lakes. This study supports the urgent need to incorporate climate impacts into vulnerability assessments and adaptation efforts for lakes.

Dec. 2015 – updates from IISD-ELA: Over the last 47 years, researchers at the Experimental Lakes Area have discovered a lot about the effects of climate change on lakes and freshwater. These are not future predictions; these effects are happening already, and include:
Part I – Our air is getting warmer
Part II – Our lakes are getting a lot less icy
Part III – Our lakes are getting darker
Part V – Our fish are getting smaller
December 4, 2015 – After COP21 Paris: The interactions of climate change and water have important implications for human poverty alleviation and sustainable development. Water is a key medium through which climate change affects human and non-human lives. Climatically-altered precipitation patterns, extreme weather events (and ensuing floods and droughts), and shifting water temperatures all contribute to alterations in the quality and quantity of freshwater available to humans, plants and animals in ecosystems around the world. In particular, water scarcity is already posing threats to human livelihoods and freshwater biodiversity. Hear more perspectives in this excerpt from the freshwater blog from the COP 21 meetings in Paris: Climate Change and the future state of our freshwaters (PDF; 2 pages).

September 29, 2015 – During the Canadian Federal election campaign there’s been a lot of talk about the economy. There has been very little discussion about Canadian’s other top priority the environment, and climate change – which is to say the federal leaders have missed the fact that you cannot sustain our economy in a vacuum and without paying attention to the underlying environmental conditions that support healthy communities.
Today, Mark Carney, the governor of the Bank of England, warned that climate change will lead to financial crises and falling living standards – hardly a positive economic outlook.
Carney said specifically that insurers were heavily exposed to climate change risks and that time was running out to deal with global warming unless the world’s leading countries do more to ensure that they do more about their current and future carbon emissions.

What about the science?
Citing some relevant scientific reports helps to provide a comprehensive review of climate impacts to aquatic systems in North America. (Citations are listed in full at the end of this article.)
The first report (Kling) examines impacts of climate change in the Great Lakes Region. The report discusses three topics: 1) future climate, 2) likely changes to lakes, and 3) actions for citizens and policy makers.
1) Future Climate
According to the report, the climate of the Great Lakes Region will grow warmer during the 21st century. By the end of the century, temperatures in the region are expected to increase by 5 to 12ºF in the winter and by 5 to 20ºF in the summer.
- Extreme heat will be more common.
- The average annual amount of precipitation will not change; however, the distribution will change – more in the winter and less in the summer. The overall effect will be to reduce surface and groundwater levels. As well, the frequency of intense rainfalls will increase, which will increase flooding events.
- Interestingly, the increased frequency of intense rain events will probably result in poorer water quality treatment efficiency of stormwater ponds due to detention time and pollution loading.
2) Changes to Lakes
The report notes these changes to lake ecosystems:
- Declining lake levels.
- Declines in the duration of winter ice.
- Shorter winter ice cover may reduce the likelihood for winter fish kills in shallow lakes.
- The distribution of many fish species will change – cold-water species will likely decline in the south and warm-water species will expand northward.
- Invasions of non-native species will be more likely.
- The duration of summer stratification will increase, adding to the risk of oxygen depletion. Lower water levels and warmer temperatures may accelerate the accumulation of mercury and other contaminants in the food chain and ultimately fish.
- Fish growth rate should increase, but not at the same rate for each species. The food chain will likely be altered.
3) Actions for Citizens and Policymakers
Finally, the report lists three ‘prudent and responsible’ actions for citizens and policymakers, representing complimentary approaches:
- Reduce the region’s contribution to the global problem of heat-trapping greenhouse gas emissions. Strategies for accomplishing this include: increasing energy efficiency, increasing conservation, boosting the use of renewable energy (e.g. wind), improving vehicle fuel efficiency, reducing the number of miles driven, avoiding waste and recycling.
- Minimize human pressures on the global and local environment to reduce the vulnerability of ecosystems. Prudent actions include: reducing air pollution, protecting the quality of water supplies and aquatic habitat, reducing urban sprawl, reducing habitat destruction and fragmentation, restoring critical habitats, and preventing the spread of invasive non-native species.
- Anticipate and plan for the impacts of climate change to reduce future damage. Adaptations may include: shifts in fisheries management and farming activities, changes in building codes, and public health management to prepare for extreme events.
The authors emphasize that these actions can be taken now. In addition to preventing or minimizing environmental impacts, these actions will also result in collateral benefits that include cost savings, cleaner air and water, improved habitat and recreation, and enhanced quality of life.
A second report (Poff) provides a less critical analysis. The report states, “… alterations in climate pose serious risk for inland freshwater ecosystems and coastal wetlands, and they adversely affect numerous critical services they provide to human populations.” The report lists eight potential impacts of climate change to aquatic ecosystems:
- Aquatic ecosystems are very vulnerable to climate change.
- Water temperature increases will shift the thermal suitability of aquatic habitats for resident species.
- Seasonal shifts in stream runoff will have significant negative impacts.
- Wetland loss in Alaska and Canada is likely to result in additional CO2 releases to the atmosphere.
- Coastal wetlands are vulnerable to sea-level rise.
- Most specific ecological responses to climate change cannot be predicted, because new combinations of native and non-native species will interact in novel situations.
- Increased water temperatures and seasonally reduced streamflows will alter many ecosystem processes with potential direct societal costs.
The manner in which people adapt to a changing climate will greatly influence the future status of aquatic ecosystems.
The authors go further to explain specific impacts to lakes. These include the increase in nuisance algae and the reduction of fish habitats with the warming of lakes. These impacts will be especially severe in shallow lakes. In addition, there will be changes in runoff – increases and decreases – which will in turn affect lake levels.
Finally, aquatic species ranges may expand or contract.
Due to the limited ability of lake ecosystems to adapt to climate change, several examples of ‘climate change insurance’ were presented (only those applicable to lake ecosystems are included here):
- Reduce nutrient loading to lakes. Protect healthy wetlands and restore degraded wetlands to enhance nutrient uptake and reduce nutrient loading.
- Locate new reservoirs only off-channel so as not to disrupt the natural downstream flow of water and sediments to critical riverine ecosystems.
- Minimize groundwater pumping for irrigation, human consumption, etc., that removes water from aquatic and wetland ecosystems.
