Experts at Dundee University have issued grim warnings as the heatwave is set to hit Scotland this week. An amber warning for extreme heat is in force across parts of Scotland with the country’s highest recorded temperature set to be broken.
Professor Sue Dawson, a hazard geoscientist at the University of Dundee, said: “The increase of temperatures well above seasonal norms is a worrying trend with temperatures due to exceed the highest levels ever recorded. The key thing for Scotland is we are not well adapted to extremes of temperature and there are risks to health, road and rail infrastructure and stresses on the water supply.
“It is not unusual to see water scarcity in Scotland, but a prolonged rise in temperatures and drought will have an impact on reservoir capacities if this continues. The long-term trends of rising temperatures are clear. Weather extremes of all kinds are becoming more common and are likely linked to climate change".
Dr Sarah Halliday, a lecturer in Geography at the University of Dundee, added: “Demand for water normally goes up during hot periods – the 2018 drought saw demand increase by 20-30%. It is therefore important people think about their water usage during this time and only use water for the tasks which are truly required.
“There are small things people can do, such as having a shower instead of baths, reducing their shower length by a few minutes, and not watering their grass.”
And she added: “With the reduced rainfall and higher temperatures there is an increasing number of reports of toxic blue-green algal blooms occurring in Scottish lochs and rivers. Blue-green algae naturally occur in our lochs and rivers and is a type of bacteria, known as cyanobacteria. This bacteria can produce toxic chemicals that are very harmful to the health of people and animals, such as our dogs.
“People using our water bodies for recreational activities over the next few days should be aware of these blooms and how to identify them.”
The news came after Nicola Sturgeon issued her own warning to Scots as the country prepares for two days of "exceptionally hot" weather.
The First Minister took to Twitter to give the advice on Sunday with temperatures expected to hit 30C on Monday and Tuesday.
An amber warning has been issued by the Met Office for Monday, affecting the east coast and south of Scotland. She said in particular people should keep out of direct sunshine and stay hydrated, as well as keep an eye on others.
Ms Sturgeon said: "The next couple of days are set to be exceptionally hot. Please take care and follow sensible advice - keep out of direct sun; stay well hydrated; and look out for others who may be suffering from the heat."
