Scotland's lochs and reservoirs have increased in temperature over recent years sparking the risk of dangerous algae, according to new research.
A report published by Scotland’s Centre of Expertise for Waters (CREW) found that climate change has caused water to warm up by up to 1C per year between 2015 and 2019.
Over this period, 9% increased by more than that – some by up to 1.3°C per year. Some 97% of monitored Scottish lochs and reservoirs have increased in temperature.
