A new study in Global Biogeochemical Cycles shows per-area greenhouse gas emissions from the world’s water reservoirs are around 29% higher than suggested by previous studies, but that practical measures could be taken to help reduce that impact.

Swedish researchers from institutions including Uppsala University have spent four years gathering data from the areas affected by the major forest fire of 2014. 

In the deep waters that underlie the productive zones of the ocean, there is a constant rain of organic material called 'marine snow'.

The smoke from the extreme forest fires on the US West Coast in September 2020 travelled over many thousands of kilometres to Central Europe, where it continued to affect the atmosphere for days afterwards. 

Researchers have identified the key factors that influence a vital pattern of ocean currents.
