Until now, insects in the tropics seemed to be the most threatened by climate change by living at the limit of their optimal temperature. An international team of scientists, with Spanish participation, has analysed the existing data and concluded that insects from temperate areas, such as Spain, could be as vulnerable to temperature increases as tropical insects.

The information of the territory provided by the laser technology from an airplane can be combined with data collected in mountain lakes with an inflatable boat and a small echo sounder to obtain three-dimensional maps. The system has been successfully tested by two geologists at the Truchillas glacial lake in Spain.
