    Insurance payouts point to climate change

    Natural disasters in 2011 exerted the costliest toll in history — a whopping $380 billion worth of losses from earthquakes, floods, tornadoes, hurricanes, wildfires, tsunamis and more. Only a third of those costs were covered by insurance. And the tally ignores completely any expenses associated with sickness or injuries triggered by the disasters. And except for quake-related events, climate change appears to have played a role in the growing cost of disasters, insurers said.

    Bt: The lesson not learned

    The more things change, the more they stay the same, as a Dec. 29 Associated Press report on genetically engineered corn notes. Like déjà vu, this news story on emerging resistance to Bt toxin — a fabulously effective and popular insecticide to protect corn — brings to mind articles I encountered over the weekend while flipping through historic issues of Science News. More than a half-century ago, our magazine chronicled, real time, the emergence of resistance to DDT, the golden child of pest controllers worldwide. Now much the same thing is happening again with Bt, its contemporary agricultural counterpart. Will we never learn?
