Watch out for climate 'surprises,' scientists warn

The long, slow process of climate change may trigger "surprise" shifts that could threaten human communities in years or decades, researchers from the National Academy of Sciences warned Tuesday.

In a 200-page report, the scientists call for an early-warning system that would watch bellwethers like Midwestern aquifers, Antarctic ice sheets and tropical coral reefs for signs that a "tipping point" is coming. Accelerated environmental changes can already be seen in the loss of Arctic sea ice and bigger wildfires since 1980, the authors said.

"A lot of these things require not only monitoring what's going on out there in the natural world as well as monitoring what we do in the human-built environment as well; how much dollar-wise do we have at risk?" said Jim White, who led the committee that produced Tuesday's report.

The committee didn't calculate the cost of establishing an early climate warning network. But even in a time of tight budgets, White said, the cost would be "trivial compared to the cost of the assets at risk."
