Rising seas. Flooding rivers. Blankets of uncontrollable wildfires. But the latest risk from global warming is a humble fungus, which could now spread across the globe. We’ve mentioned the danger of antibiotic resistant fungi before here(LSS 21 10 24 et al) But we never thought to tie it to climate change.
Well all that’s just changed. Because according to a new study by Dr Norman van Rhijn of Manchester University, reported here by Alex Croft of the Independent, via Yahoo [1] dangerous strains of the Aspergillus family of fungi are starting to spread . If we carry on burning fossil fuels at the rate we do now, the strain A. fumigatus will probably extend its range by 77% by 2100, pushing up into polar regions such as Alaska. And the trend is worrying experts from many fields.[2] For one thing, fungi have an immense potential to damage drops. But they also pose a clear and present danger to human health, especially in those with weaker immune systems, such as the elderly and children. They may also produce substances such as aflatoxins which may cause liver damage and even cancer[3] It’s hard to get an exact figure which parses the number of deaths caused directly by fungi, and those cases where they become an opportunistic secondary infection. But about 3.5 million a year might not be a bad ball park figure. As the fungi become resistant to antibiotics and fungicides, this figure will grow and grow.
This is a bank holiday weekend in our country. People will be doing bank holiday things. A great many cars will be cleaned, tents put up, boats sailed and drinks drunk. But , we can’t help thinking, wouldn’t it be better to put all the fun on hold for a bit, until problems like this have been finally sorted out?
