As talks came to an end in Copenhagen, the World Health Organization tried to explain that climate change is about more than the environment -- it's a human health concern too.
As WHO scientist Diarmid Campbell-Lendrum said on the News Hour on Thursday, "Three and a half million die from under-nutrition. That's entirely dependent on agricultural production. And all of those deaths occur in the parts of the world that are going to be most affected by climate change."
Malaria is another heat-sensitive global health threat, which is expected to worsen with changing weather patterns. But, on the bright side, the World Health Organization reported this week that malaria-fighting funds, which went from $300 million in 2003 to $1.7 billion this year, are paying off. In a third of the 108 "malarious" countries, reports of sickness dropped by more than half since 2000.
And the Bill and Melinda Gates Foundation just awarded researchers nearly $10 million to create a malaria vaccine.
However, in case you're visiting a "malarious" country any time soon, here's some tips from the Centers for Disease Control and Prevention on keeping clear of the mosquito-borne bug.
