Pengiun clues

 
Published: Sunday 31 October 1993

AS THE global warming debate heats up, scientists are looking towards the most unlikely source for clues -- penguins. They suspect the availability of fish on which penguins feed is increasing in the waters of the Antarctic Ocean, which are warming slightly. Therefore, fatter penguins would indirectly confirm the greenhouse effect, suggest researchers.

Next year, a team of researchers from New Zealand and USA will start monitoring the weight of about 100 penguins, tagged with electronic detectors, for a period of five years.
