The retreat of Arctic glaciers that end in the ocean since 2000

– By Will Kochtitzky and Luke Copland –

The glacier-ocean interface is a dynamic part of glacier and fjord systems. All glaciers, both land and marine-terminating, lose mass due to melt, but those that end in the ocean also lose mass by the calving of icebergs (Figure 1). Ocean currents can bring warm water and accelerate the retreat of glaciers that end in the ocean, while glaciers can bring nutrient rich meltwater to the ocean and locally increase biological productivity.

Peatlands at COP26

– By Lorna Harris –

Our planet is warming, and this will have profound impacts on ecosystems and the species that depend on them, including us. This was one of the main messages of the new IPCC report, published in February 2022. The risk to high-carbon ecosystems and the potential amplification of global warming resulting from the release of greenhouse gases (GHG) from these ecosystems was highlighted, particularly for peatlands.

Declining numbers of stations and automation of surface snow depth observations pose important challenges for applications requiring long term consistent surface snow depth information over Canada

– By Ross D. Brown –

Environment and Climate Change Canada’s (ECCC) snow depth observing stations represent the primary surface snow depth observing network in Canada, providing real-time input on surface snow cover conditions that contributes to increased skill and reduced air temperature biases in forecast models.

Why 400+ academics wrote to the Finance Minster

– By Haley Alcock following an interview with Dr. Christina Hoicka –

On January 19, 2022, in an open letter to Finance Minister Chrystia Freeland 400+ academics and researchers urged the federal government not to introduce a proposed tax credit for carbon capture, utilization and storage (CCUS). Insisting that the tax credit would constitute a new fossil fuel subsidy, these academics made clear that research and science has an important role to play in pointing out discrepancies within the nuance of governmental climate policy.

As climate science researchers and educators, we need to do more for our students than just teach them about their dismal futures

– By Dr. Heather Short –

I resigned from my tenured position teaching climate science at a small college in August of this year. It wasn’t to take a better job offer, or to use as a bargaining chip for better pay; it was an act of conscientious objection to an educational system that is preparing students for a future that will not exist. Students are climate-crisis-fatigued, angry, confused, hopeless, and often in denial because the world outside of the classroom is in denial.

CMOS Bulletin Solidarity Statement with Wet’suwet’en land defenders

The CMOS Bulletin stands in solidarity with members of the Wet’suwet’en Nation as they peacefully defend their unceded territories in the face of militarized police action, raids and arrests by armed RCMP officers. As a science communications platform that exists for the advancement of climatology, meteorology and oceanography in a time of climate emergency, the Bulletin understands our specific responsibility to support Indigenous peoples’ efforts to protect their lands, waters and peoples against the expansion of fossil fuel infrastructure.
