Bill Radke: Hundreds of scientists, policymakers and corporate leaders are meeting this week in Geneva. They are trying to connect the dots between climate predictions and what businesses can do about them. From the Marketplace Sustainability Desk, Sam Eaton reports

Sam Eaton: The U.N.'s World Meteorological Organization says when it comes to making investment decisions, the past is no longer a reliable indicator of the future. That means everyone from government leaders to business executives will rely more heavily on climate model predictions.

Director Michel Jarraud says agriculture is a prime example:

Michel Jarraud: The crops which will thrive in the new climate may not be the same as in the old climate. So we can give better advice based on the prediction.

Jarraud says climate change will affect every sector of the global economy from forestry and fisheries to tourism, health care, and transportation. And that means climate models will be an essential tool for the decision makers in those sectors. The challenge, Jarraud says, is ensuring that poor countries will get the same access to the latest climate projections as rich countries will.
