Research reveals that Canada and Alaska's vast boreal forests, alongside the treeless shrublands just north, are facing significant threats from climate change, potentially being among the hardest hit regions over the next 500 years.

The study, a collaboration between the UK's White Rose universities of York and Leeds, Oxford, Montreal, and ETH in Switzerland, used advanced climate models to predict how the world's ecosystems could change by the year 2500 due to varying levels of carbon dioxide in the atmosphere.
Exploring the Future: How Climate Change Could Reshape Boreal Forests and Tundra Shrublands by 2500
Unlike most climate forecasts, which look up to the year 2100, this team delved much deeper, exploring how life on Earth—from humans to wildlife and plant life—might need to adapt to the climate changes that will continue beyond this century. Their findings are alarming: the boreal forests, crucial for storing carbon and providing clean water, and the tundra shrublands, vital for regulating the Earth's climate, could both face severe impacts.
The Unseen Consequences: Boreal and Tundra Ecosystems at the Frontline of Climate Change
As the planet warms, these areas are already witnessing changes, such as new plant species in the tundra that previously couldn't survive the cold. This warming could lead to a decrease in the planet's ability to reflect heat, exacerbating global warming further. The study warns that without quick action to reduce greenhouse gas emissions, many regions could become too hot for comfortable human habitation, demanding drastic changes in our daily lives.
The migration of animals and plants, attempting to adapt to these changes, is set to increase. However, trees and some species move slower than others, which could lead to the loss of certain plants and animals, fundamentally altering today's ecosystems. Dr. Christopher Lyon, a lead researcher from the University of York, emphasizes the importance of looking beyond current climate goals to understand the full scope of changes our descendants will face, including the potential need for radical adaptations.

The Urgent Need for Global Cooperation and Long-term Environmental Planning
The study also suggests that as boreal regions warm, they might become more populated, increasing stress on these ecosystems and highlighting the necessity of international cooperation for effective climate adaptation. Dr. Bethany Allen from ETH Zurich stresses the urgency of protecting these critical environments and the potential need for large-scale geographical shifts in their conservation over the coming centuries.
This research not only sheds light on the long-term effects of climate change but also calls for immediate action to mitigate these impacts, underscoring the importance of thinking ahead for future generations. The study is published in the journal Philosophical Transactions of the Royal Society B and was supported by the White Rose Collaboration Fund and the Leverhulme Trust via the Leverhulme Centre for Anthropocene Biodiversity.
