Accelerated Water Loss in Northern Peatlands Threatens to Intensify Fires and Global Warming

A group of 59 international scientists, led by researchers at Canada’s McMaster University, has uncovered new information about the distinct effects of climate change on boreal forests and peatlands, which threaten to worsen wildfires and accelerate global warming.

A group of 59 international scientists, led by researchers at Canada’s McMaster University, has uncovered new information about the distinct effects of climate change on boreal forests and peatlands, which threaten to worsen wildfires and accelerate global warming.

Manuel Helbig and Mike Waddington from McMaster’s School of Geography and Earth Sciences gathered observational data from collaborators in countries across the boreal biome. Their study of how ecosystems lose water to the atmosphere appears today in the journal Nature Climate Change.

The unprecedented detail of their work has highlighted dramatic differences in the ways forests and peatlands regulate water loss to the atmosphere in a warming climate, and how those differences could in turn accelerate the pace of warming.

Most current global climate models assume the biome is all forest, an omission that could seriously compromise their projections, Helbig says.
