Germs under the permafrost: too scary?

„I hope I wasn’t too scary“, said Professor Andrej Grjbovski to me after our panel discussion in Bonn the other night. He works with the Norwegian School of Public Health in Oslo and the Northern State Medical University in his native Arkhangelsk in Russia.
Well I’m not for panic-mongering, but given some of the information our experts were coming out with, maybe you can’t be too scary.
Prof. G. was in Bonn both for the conference at the environment ministry and the public panel discussion. (See links on the Ice Blog 30.11.2010). Amongst other things, he’s involved in a WHO project to monitor the effects of climate change on health in a region of northern Russia.
He was referring in particular to the health dangers from melting permafrost. There are all sorts of dangerous things buried in the permafrost, which come to the surface as it melts. Not for nothing do some people refer to a “timebomb” in the Arctic. After outbreaks of diseases like anthrax, for instance, animals were buried in mass graves. The anthrax spores can survive in there and pose a new threat to health as they emerge again. Yes, Professor, that is definitely in the “scary” category.
But a changing climate poses all sorts of less “spectacular” but nonetheless crucial challenges to health care around the globe. The WHO says the 2003 heatwave killed 70,000 people in Europe. Heatstroke and heart attacks can be fatal to the particularly vulnerable, especially older people. Children and the homeless were also mentioned as amongst the vulnerable population groups.
Floods are another example. Apart from deaths from drowning, there’s the water pollution and fungus left over in the aftermath, which can result in the spread of infectious diseases, respiratory and digestive problems etc.
And of course species are moving to different areas – including, for instance, the mosquito types that are bringing illnesses like Dengue to Europe.
Needless to say – but I’m doing it anyway, sometimes we have to keep reminding ourselves of the obvious – it’s the people in poorer countries or areas who suffer most from the higher health risks through climate change. Germany has an adaptation strategy involving early warning systems for extreme weather events or the spread of infections and flood protection systems. The deputy director of the German meteorology office the DWD Paul Becker told me in an interview capacity building and passing on the necessary expertise to adapt to the health risks posed by a changing climate were the key issues in helping the developing world, whereby finding the necessary funding was probably the main challenge.
Incidentally, on the sidelines of the Cancun talks, Germanwatch published its latest Climate Risk Index. It says more than 650,000 people died in around 14,000 extreme weather events over the last two decades.
