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.
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.
In the fifth assessment report (AR5), world experts from Working Group 1 summarized our collective state of knowledge and uncertainties in relation to climate change science.
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.
