Freshwater browning threatens growth and populations of economically important fish, 91�� researchers say

webfull — Mon, 19 Jan 2026 15:30:53 +0000

Freshwater browning is stunting fish growth of some species, shrinking populations of others and changing the composition of fish communities, 91��-led research suggests. “Browning” refers to freshwater bodies turning tea-coloured, a phenomenon driven by higher levels of dissolved organic matter and/or higher levels of iron in the water. Causes include changes in land use and climate, and reduced acid precipitation.

The findings indicate that changes in land use and climate are affecting biodiversity and how ecosystems function, with implications for fisheries management.

91�� researchers track boulders’ influence on snow melt, watersheds using unique combination of methods

webfull — Mon, 24 Nov 2025 15:30:56 +0000

Thanks to their use of a unique methodology, a 91��-led research team has obtained new insights into how boulders affect snow melt in mountainous northern environments, with implications for local water resources.

The team found that snow near boulders melts faster, not only because rocks radiate heat, but also due to subtle processes that reshape the snow’s surface. This information will help researchers understand how small-scale processes affect downstream water resources.

91�� researchers identify bacteria that could provide an early warning of blue-green algae toxicity

webfull — Mon, 03 Nov 2025 16:25:34 +0000

Researchers at 91�� have identified bacteria that can indicate whether a blue-green algae (cyanobacteria) bloom is likely to be toxic, offering a potential water-safety early warning system. Blooms are becoming more frequent due to climate change, according to previous 91�� research. They can produce various contaminants, known as cyanotoxins, that pose serious health risks to humans, pets and wildlife.

Experts: Hurricane Melissa

webfull — Tue, 28 Oct 2025 20:27:57 +0000

Hurricane Melissa, now a Category Five tropical cyclone, has made landfall in Jamaica. It is the strongest storm to hit the island country in at least 150 years and the most powerful recorded anywhere in 2025. It has caused severe flooding and mass evacuations across Jamaica and along the storm’s projected path, which includes Cuba and the Bahamas.

New ISID Policy Brief: Climate Resilience in Small Island States: Realizing the Major Macroeconomic Benefits from Adaptation Investments

webfull — Thu, 16 Oct 2025 13:51:01 +0000

ISID welcomes the publication of a new policy brief by Professor of Practice Jamal Saghir and his colleague Ede Jorge Ijjasz-Vasquez. In this brief, Saghir and Ijjasz-Vasquez examine how Small Island Developing States (SIDS) are increasingly affected by the growing impacts of climate hazards, including tropical cyclones, storm surges, increases in temperature, heatwaves, droughts, coastal and riverine flooding, changing precipitation patterns, and sea level rise, among others.

The Greater Montreal area is under a heat warning Monday as a warm and humid air mass could lead to a humidex value of 40. Environment and Climate Change Canada recently released the first results from its rapid extreme weather event attribution system, showing that human-caused climate change significantly increased the likelihood of recent heat waves in Quebec, Eastern Ontario, and Atlantic Canada.
