Québec’s hardwood trees could move north. Here’s how that could affect the boreal forest landscape

Research shows that the distribution of temperate hardwoods (sugar maple, red maple and yellow birch) could be shifting northward, which would have serious consequences for the boreal forest.

Forest fires were mostly started by lightning. Their spread was then exacerbated by a lack of precipitation and abnormally high temperatures. (Victor Danneyrolles)

Québec’s summer 2023 wildfires were the most devastating in 50 years. Is the worst yet to come?

The forest fires of the summer of 2023 in Québec were devastating. It was the worst year in 50 years. But with climate change, the worst may be yet to come.
Rising temperatures are not just directly lethal to fish but also result in hormonal imbalances which threaten entire populations. (Jonathan Munera L.)

How climate change-induced stress is altering fish hormones — with huge repercussions for reproduction

Climate change is causing higher levels of stress in fish, and the resulting hormonal imbalances are fundamentally altering entire populations.
