Thank you, Madam Chair.
Thank you for the opportunity to present before you today to inform the committee's study of critical northern infrastructure projects and regional strategies from the perspective of environmental observations and monitoring.
My name is Dilhari Fernando, and I'm a Director General with the Meteorological Service of Canada and Environment and Climate Change Canada. My colleague Chris Derksen is a research scientist with the science and technology branch of the department.
Environment and Climate Change Canada informs Canadians about protecting and conserving our natural heritage and ensuring a clean, safe and sustainable environment for present and future generations. Our programs focus on minimizing threats to Canadians and their environment from pollution; equipping Canadians to make informed decisions on weather, water and climate conditions; and conserving and restoring Canada's natural environment.
Environment and Climate Change Canada is a science-based department. The department operates a vast and diverse array of infrastructure in the north and in the Arctic to gather environmental data and undertake research to support the delivery of departmental services and to provide important data and information to support the work of many others, including other federal departments and agencies, other levels of government, academia, the private sector and the global community.
In addition to buildings used for research, storage and staff accommodation, the department is the steward of a vast range of specialized observing infrastructure that we use to collect environmental data such as precipitation, air pressure, air quality, etc. This data is used for the production of weather forecasts and warnings, climate information and services, ice services, and long-term records of climate conditions.
In the case of the Eureka installation at Ellesmere Island in Nunavut, Environment and Climate Change Canada is also the principal steward of the runway, which is essential for aircraft landings and is a critical access point for federal and other visiting scientists.
Let me provide some details. The Meteorological Service of Canada is the authoritative source for weather, water quantity, air quality and ice information and services. We provide a broad range of services, including issuing public weather forecasts and alerts for approximately 90 communities in the north; monitoring sea ice floes and issuing marine forecasts, advisories and warnings; maintaining long-term records of ice and climate conditions; and collecting information on water levels and flows in Canada's major water basins, including those that flow into the Arctic Ocean.
To provide these services, we operate national monitoring networks to provide information about past and present conditions of the atmosphere, climate, water and ice. Specific to the north and the Arctic, we operate approximately 137 automated weather stations, 21 volunteer-run weather stations, 93 aviation monitoring stations, 16 upper-air operations, 11 lightning detection stations, 13 climate monitoring stations, 34 drifting buoys, one satellite receiving station and 233 hydrometric stations.
Environment and Climate Change Canada also conducts a range of research and monitoring in Canada's north and Arctic to generate important information to help us understand the unique and changing nature of northern ecosystems. As part of this work, we conduct science that leads to improved understanding of how and why Canada's climate is changing and what future climate conditions are projected. Surface observations, satellite data and climate models are fundamental to this sort of research.
The department operates a variety of science and technology facilities and programs in Canada's Arctic, including four permanent High Arctic multi-purpose research stations located at Eureka, Resolute, Alert and Iqaluit. Environment and Climate Change Canada is the primary steward at Eureka, located in Nunavut. Data gathered at Eureka is important for weather modelling and weather forecasting and is shared globally. Eureka is also a key location for acquiring High Arctic observations to support other important science and research programs.
As the steward of this infrastructure, we are responsible for overseeing and maintaining all the associated infrastructure on the site, including the runway, the buildings and the energy generation facility, and for ensuring safe living conditions, such as potable water and sanitation for departmental staff, DND staff and visiting scientists.
I would also like to bring your attention to Alert, at the northern tip of Ellesmere Island. Located about 700 kilometres from the North Pole, this is the northernmost inhabited place in the world. Alert is also an important location for upper-air observations, which are critical for weather forecasting, both in the north and in the south, and it is the sentinel site for climate and greenhouse gas observations.
Given the important and unique features of sites such as Eureka and Alert, it is important to note that infrastructure in the Arctic and in the north faces unique operational challenges and is subject to significantly higher operational costs and risks. Remote location, long periods of darkness, and severe weather require that these facilities be fully self-contained for power, water and sanitation. Air is the principal means to bring in supplies and people, which underscores the importance of year-round, safe runways. We also need specialized equipment in remote areas, with design features that allow this equipment to operate in the unique northern and Arctic climate, such as in extreme cold, and have resilience to things such as wildlife. Solutions that are viable in the south, such as solar power, are not always easily transferrable to the north.
In terms of the effects of climate change on infrastructure in the north, the special report recently released by the Intergovernmental Panel on Climate Change, or the IPCC, entitled “Global Warming of 1.5°C”, indicated that human activities are estimated to have caused approximately 1°C of global warming so far. The report also noted that vulnerable regions, including the Arctic, experience warming two to three times higher than the global average.
Over the past 40 years, changes over the north and the Arctic include loss of snow cover and sea ice, and changes to permafrost. These changes are consistent with those observed in other northern regions, including Alaska, northern Europe and Russia. There is evidence from climate model simulations that these observed changes in the Arctic and in northern Canada will continue in the coming decades.
There are important factors when considering the possible effects of climate change on infrastructure in the Arctic. Key points to consider include the following: Virtually all of the Canadian north is underlain by permafrost, and the integrity of many northern ecosystems and built infrastructure is dependent on the stability of the permafrost; permafrost is undergoing rapid change, which could threaten the structural stability and functional capability of existing infrastructure; changing coastlines and the loss of sea ice further increase the risk of flooding from rising sea levels and storm surges in some areas.
In conclusion, Environment and Climate Change Canada relies on a wide range of infrastructure across the north to gather important environmental observations for use in the delivery of key services such as weather forecasting and for research on issues such as climate change impacts in the north. Ensuring adequate density, distribution and life-cycle management of infrastructure in the north to enable observations and research is particularly challenging given Canada's vast and remote landscape. This underscores the importance of project management, adaptation to innovative technologies, and the identification and mitigation of risks as we move forward.
Thank you very much.
