Recent MA graduate, Sheena Stewart and colleague Marley Kress, continue to pull valuable information from the history of trees to apply lessons from past climates to planning for tomorrow.

Manitoba, Saskatchewan, and Alberta present unique challenges for detecting and communicating climate change as well as managing uncertainty. Those living across the Prairies know that variability is a part of life and have been adapting to the shifts in weather between seasons for generations—but the Prairies are also one of the fastest warming regions in Canada due to human-caused climate change.


We have released these guides to help navigate these challenges and better understand the different types of uncertainty and how they can be managed. Recognizing, understanding, and accounting for uncertainty can inform robust adaptation and decision-making, and help prepare for the future. 


The Uncertainty Primers are your technical guides to confronting the natural uncertainty in climate projections and incorporating this uncertainty into decision making. We offer a longer, technical guide for the advanced practitioner, a clear-language summary of uncertainty in climate modeling, and a smaller abstract to suit your needs.


A webinar to discuss these materials further and how to use them in your work is being created. Stay tuned for an announcement from PARC and ClimateWest for an early 2023 date!

PARC Director, Dave Sauchyn, explains how historical information from tree rings can provide insight into the climate of Saskatchewan and the Prairies, yielding much more insight into previous flood and drought events than current weather observations. Read the short article below to find out how PARC's Tree Ring Lab is utilizing these paleoclimate records to reconstruct Prairie climates.

From the article:

“This tendency to perceive floods, storms, and drought as ‘unprecedented’ is common. After all, it is human nature to view extreme conditions as out of the norm, given that our general frame of reference – such as a human lifespan – is relatively short.

The tree rings capture natural climatic variability before the world’s climate was significantly modified by human activity.”

In a podcast with Canadaland's Sarah Lawrynuik, PARC Director, Dr. David Sauchyn, discusses the recent plight of Manitoba's 2021 drought juxtaposed with heavy flooding in the southern and central parts of the province this year - a term called "whiplash". 


Check out the link below to learn why the Prairies are uniquely situated for the world's most variable climate, the role this variability plays in water resources management, and the challenges brought upon industries and biodiversity.

From the article:

“This whiplash is the kind of condition that we expect in a warmer climate,” he says. “Now, I’m not saying that the drought of last summer and the flooding of the spring is caused by climate change — these are perfectly natural conditions. But there’s pretty good science to suggest that the severity of the drought and the severity of the flooding is, to some extent, increased as a result of a warmer climate.”

In response to user needs, PARC implements second website to highlight applications of unique paleoclimate records and high-resolution regional climate modeling in the Prairie provinces.


This is a gateway to better explain the what, where, why and how of our data:

  1. the kinds of data we are producing and working with;
  2. where we are applying these data;
  3. how we are utilizing these data; and
  4. why we are doing this.

The who has always been the Canadian climate user community, which includes both public and private partners interested in identifying and / or evaluating risks associated with climate change.


The new site also provides us an opportunity to expand the services we can offer. In the coming months we will begin building the Climate Risk Indicator Atlas of the Prairies, which will provide an interactive gateway to regionally relevant data and tools for physical risk assessment. This resource is intended to provide sector specific indicators of climate risk to help guide evaluations of risk in the face of uncertainty.


Many changes and updates will take place to the site on an ongoing bases, including new case studies to be featured and interactive features of our data. Stay tuned for these!


The broader vision and mission of PARC - to provide scientific research that delivers practical and regionally relevant climate data, information and knowledge in support of adaptation to climate variability and change - can be found expanded upon at There you will also find more general information about our 21-year history, rich archive of past projects and resources, and our Tree-ring Lab.
