In what’s likely to be the hottest year on record, nations are gathering to try and hash out faster action on climate change. Here are the three main issues facing negotiators.
The combined impact of increasing temperatures (2 to 8°C by 2100) and forest development in the mixed boreal forest could modify the growth and distribution of temperate species.

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.

From dark dragonflies becoming paler to plants flowering earlier, some species are slowly evolving with the climate. Evolutionary biologists explain why few will evolve fast enough.
Climate modelling that best accounts for the processes that sustain plant life predicts plants could absorb up to 20% more CO₂ than the simplest version predicted.

Climate action should be framed not as a sacrifice but as an investment that can generate economic savings and improve human and ecosystem health today.
Forest fires were mostly started by lightning. Their spread was then exacerbated by a lack of precipitation and abnormally high temperatures.

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.

Back when there were Arctic alligators and turtles, ‘polar stratospheric clouds’ kept their world warm. Research suggests these clouds contribute to the ‘missing warming’ in climate models.

The same instruments used to measure earthquakes pick up vibrations as ocean waves put pressure on the sea floor. Four decades of data tell a story about ocean storms.

Environmental degradation and altered landscapes, both due to human action and climate change, increase the incidence of already known diseases and the risk of new zoonoses emerging
The first comprehensive assessment of trends in Southern Ocean ecosystems reveals an urgent need to address climate change. The summary for policymakers can guide decision-makers.
Rising temperatures are not just directly lethal to fish but also result in hormonal imbalances which threaten entire populations.

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

Understanding how both cloud cover and temperature work to promote coral bleaching provides valuable insight into how reefs will change over various climate scenarios.
