Global warming threatens public health
Hundreds of scientists from all over the world have gathered in Stockholm this week to discuss the health effects of the climate change.
Scientists can already see the effects of climate change on public health in connection with extreme natural disasters. But they also warn that the warmer temperatures could mean that tropical deceases that are rare in southern Europe and don't exist at all in northern Europe, such as dengue fever, could spread.
One already visible effect is that mosquitoes carrying malaria in mountainous areas in Africa and South America are now able to survive at much higher altitudes and this summer France had its first outbreak of dengue fever.
Elisabeth Lindgren, from the Karolinska Institute in Stockholm, told Swedish Radio News that even Sweden can expect previously nonexistent deceases to spread here as well.
"(Dengue fever) can survive in large parts or central Europe with today's climate but we are concerned that it might spread, as it gets warmer, all the way to southern Sweden."
