Heat affects animals

Many animals have suffered from the record heat.

Animals’ metabolism is faster than normal in hot weather. Therefore, animals consume more energy.

For example, bears do not get enough food for hibernation.

Hedgehogs and frogs also need food, because they hibernate in the winter. In it, the animal’s body temperature drops close to zero.

Salmon like cool water, and long, warm, dry weather is bad for them. Salmon need a lot of water as they move up the river to the spawning grounds to breed.

Insects also suffer from excessively warm weather. That’s why there are fewer insect species than normal during the near summers.

There has been a strong heat wave in the Gulf of Finland and the Red Sea. The sea temperature there has been more than 5 degrees above average.

The water along the entire coast of Finland has also been very warm even in autumn.
