Newsletter – February 2023

Message from the team

Thank you for subscribing to our monthly newsletter. Our goal is to provide updates on new climate change data products, tools, and guidance documents available on

This month, we want to tell you all about the brand-new statistically downscaled CMIP6 data just released on These new data constitute a major update to the site, so there’s a lot to unpack.

As always, if you or your organization have information you would like to see promoted in our newsletter, please contact us at [email protected].

What exactly is “CMIP6”?

The Coupled Model Intercomparison Project (CMIP) is a climate modelling collaboration that aims to increase our understanding of climate change. It has been running since the 1990s and involves the participation of many international research organizations. The climate model data from the most recent phase of CMIP, known as CMIP6, was featured prominently the latest IPCC assessment reports.

How have the data been downscaled?

Statistical downscaling is the process of using statistical techniques to adjust the resolution of global climate model data to a more local or regional scale, making it more applicable to specific geographic locations. In this specific case, the data has been downscaled to a grid approximately 10 by 6 km in resolution. Just like the previous-generation downscaled CMIP5 data on, the new data is available for a range of variables, including temperature and precipitation, and covers a range of time periods, from the 1950’s to the end of this century.

Accessing the new CMIP6 data

The CMIP6 dataset is now the default option on It has been seamlessly integrated across the website, meaning the way you access and view data on won’t need to change.

Why don’t you start by exploring the map. You can zoom in on the map until the grid appears, at which point you can click on the map to access the underpinning data.

New scenarios

CMIP6 also introduced shared socio-economic pathways, or SSPs, more broadly to the climate adaptation community.

Shared socio-economic pathways (SSPs) are a set of scenarios developed to explore the potential social and economic changes that could occur over the 21st century. These scenarios are used to inform climate modeling and projections of future greenhouse gas emissions. They replace the previous generation of scenarios, known as RCPs.

There are five SSPs, each of which represents a different trajectory of social and economic development over the 21st century. These pathways are based on a range of assumptions about population growth, technological change, economic development, and other factors that could influence future greenhouse gas emissions. provides data for three different SSPs: SSP1-2.6 (Sustainable Development), SSP2-4.5 (Middle of the Road), and SSP5-8.5 (Fossil-Fueled Development).

What about the “old” CMIP5 data?

If you wish to view the CMIP5 data, you can do so by using the toggle options found on the variable and location pages. Both the CMIP6 and CMIP5 datasets have been downscaled and bias-adjusted using the BCCAQv2 methodology, and are available at the same spatial scale.

The  team  recommends  that  you  use  CMIP6  for  new  work requiring  future  climate projections.  For  prior  work  based  on  CMIP5  projections,  we  recommend  comparing  CMIP5  with

CMIP6 to determine if updates may be required. New CMIP projections are generally available on a 5-8  year  cycle:  as  new  climate  projections  become available,  they  should  be  incorporated  into  the adaptation cycle.

What’s coming next?

The Learning Zone on is getting a major upgrade this year. Over the next few months you’ll find more articles that are tailored to different learning levels and learning outcomes.

We’re putting the final touches on a set of articles related to future weather files. If you’re not sure what a ‘future weather file’ is and would like to learn more now then check out our latest blog article on the subject.

Be sure to stay subscribed so you don’t miss out on future updates and product launches.
