Study Notes

  • Global warming causes winters to be warmer and shorter, altering the habitats of plants and animals.
  • As a result, bears no longer hibernate as much as they used to, and instead continue to search for food during the winter, making them more aggressive towards humans.
  • The duration of hibernation is decreasing, and bears are not regenerating or finding food, leading to increased aggression.
  • Many migratory bird species, such as the curruca capirotada, are no longer migrating due to climate change, instead staying in their year-round habitats.
  • Some species, like the petirrojos, remain in their home territories, while others, like storks and cranes, follow their genetic instincts and migrate, but face increasing deserts and decreasing food sources in Africa.
  • Scientific research has shown that salmon are up to 8% smaller than they were in the past, likely due to warmer water temperatures causing them to mature faster and return to their spawning rivers at a younger age.
  • The green sea turtle is also at risk of extinction, with the sex of its hatchlings determined by the temperature of the sand, with 28°C producing only males and 32°C producing only females.
  • In the northern parts of the Great Barrier Reef, only females are being born, making it difficult for them to reproduce due to a lack of males.
  • According to the World Wildlife Fund, nearly half of all animal species are at risk of extinction due to climate change.
