History no longer a indicator of weather

Because of climate change, historical weather data is no longer a good indicator of trends to come and a good guide for decision-making, World Meteorological Organisation chief Michel Jarraud said on Thursday.

In an interview to UN radio, Jarraud said many socio-economic sectors are highly dependent on climate conditions to make decisions on the long-term nature of projects.

Noting that it is important these decisions be made on the basis of the best possible scientific information, he said that the goal of WMOs World Climate Conference, next week in Geneva, is to link scientists and decision-makers. In the past, forecasts were made by taking statistics of past decades into account, but now with climate change, these statistics are changing, Jarraud told UN Radio.
