Canada's changing climate report


On April 2, 2019, the federal Government of Canada published the 2019 version of Canada's Changing Climate Report. I co-authored Chapter 7 of this report about the Changes in Oceans surrounding Canada. In this Chapter, we discuss changes observed in the past and projected changes in the future for the ocean's salinity, temperature, currents, sea level, acidity and dissolved oxygen.

Toronto's climate projections to 2100


Environment and Climate Change Canada (ECCC), in collaboration with several partners, launched the climate data portal in June 2019. In this blog post, I used a subset of graphics from in order to paint a picture of how the city of Toronto's climate may evolve during the 21st century under three greenhouse gas emissions pathways (RCPs 2.6, 4.5, 8.5).  The portal contains similar data and graphics for thousands of Canadian towns/cities from coast to coast to coast. 

Intergovernmental panel on climate change



The IPCC (Intergovernmental panel on climate change) was created in 1988 by the World Meteorological Organization (WMO) and the United Nations Environment Programme (UNEP). IPCC provides governments at all levels (federal, state, province, cities) with scientific information they can use to develop climate policies.

Climate change 2021 - the physical science basis

The sixth assessment report (AR6) will be released in 2021. Information on the outline of the report and the proposed timeline are available on the IPCC website.

SROCC 2019 - Special Report on Ocean and Cryoshere in a changing Climate

In April 2016 at Nairobi, Kenya, the IPCC 

agreed to produce a special report on ocean and cryosphere in a changingclimate change. The summary for policy makers and the supporting technical summary and chapter reports will be approved at the 51st session of the IPCC in Monaco, September 20-23. I will part of the official Canadian Government delegation at this IPCC session.
