Warmer springtimes are coinciding with rivers flooding and could change the European landscape, scientists warned. Researchers from the University of Glasgow and Umeå University in Sweden analysed data collected since the 1960s on flood peaks and daily temperature in locations across Europe. It showed that climate change is disrupting the rhythms of spring growing and river flooding across Europe – which could pose new problems for biodiversity and food security in floodplains. The data, published in the journal Geophysical Research Letters, demonstrates for the first time an increasing overlap between the onset of spring and the highest points of seasonal flooding. Scientists found the thermal growing season – defined as periods where the temperature rose consistently above 5°C, encouraging plants and trees to begin to grow – has been consistently starting earlier in the year.

In the turbid, frigid waters roaring from the glaciers of Canada’s high Arctic, researchers have made a surprising discovery: for decades, the northern rivers secretly pulled carbon dioxide from the atmosphere at a rate faster than the Amazon rainforest. The findings, published in the Proceedings of the National Academy of Sciences, flip the conventional understanding of rivers, which are largely viewed as sources of carbon emissions.
