•  

  Many tropical insects face extinction by the end of this century unless they adapt to the rising global temperatures predicted, US scientists have said.

  Researchers led by the University of Washington said insects in the tropics were much more sensitive to temperature changes than those elsewhere.

• Unlike warm-blooded animals, cold-blooded organisms cannot regulate their body temperatures by growing a coat of fur or shedding it when it gets warm. They are instead limited to either seek shade when hot or sun themselves when cool.
