Nonlinear measurements might be expected to confound, but do they belong in a statistical model hierarchy?

– By Rick Danielson Jr –

A statistician and physicist were discussing an experiment over a pot of tea, when this hypothetical exchange occurred: “I know we are working in the right units, but do you think that some of our measurements are nonlinear?” Puzzled, the physicist took a sip before responding, “Are you saying that individual measurements could be nonlinear? Is that a thing?”

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.

First-ever Weather and Water Project WET Workshop

– By CWRA Project WET Canada –

The first joint CWRA Project WET Canada and Canadian Meteorological and Oceanographic Society (CMOS) activity was a one-day workshop cohosted for the Association of Science Teachers Conference in Halifax in October 2021. The Project WET 2.0 workshop was led by Lizabeth Nicholls and Maxine Koskie from CWRA Project WET with involvement from three CMOS National Executive and Council members who live in Halifax: Jim Abraham, Serge Desjardins, and Aldona Wiacek.

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.

Listening to Narwhal

– By Kristin Westdal –

Mittimatalik (formerly Pond Inlet) is a small hamlet on the north end of Baffin Island in the Canadian Arctic. Surrounded by mountains, rivers, and glaciers, the community sits on the shores of beautiful Eclipse Sound. These waters are a biological hot spot, teeming with marine life, including the world’s largest population of narwhal each summer. To protect this habitat, Canada established the Tallurutiup Imanga National Marine Conservation Area.

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.
