Arctic peatlands may release potent greenhouse gas as permafrost thaws

From ABC Science, 30 May 2017: Arctic peatlands may become a substantial source of a greenhouse gas 300 times more potent than carbon dioxide when they thaw, a new study suggests. The study by a team of Scandinavian scientists indicated that thawing permafrost could release nitrous oxide (N2O) — also known as ‘laughing gas’ — Continue reading Arctic peatlands may release potent greenhouse gas as permafrost thaws

Urban heat islands: cooling things down with trees, green roads and fewer cars

From the Guardian, 21 February 2017: When it comes to coping with heatwaves, our own cities are conspiring against us. Road surfaces, pavements and buildings all contribute to keeping urbanised environments three to four degrees hotter than surrounding non-urbanised areas.
