Here are some consequences.

  1. The rising temperatures have accelerated the melting rate of mountain glaciers, ice sheets covering West Antarctica and Greenland, and Arctic sea ice. This as a result has had a negative impact on the ecosystems in these regions. Many species of flora and fauna found in these areas have been pushed to the brink of extinction
  2. The accelerated melting rate of ice water has caused the sea levels to rise at an alarming rate.
  3. It has caused changes in the water cycle, precipitation i.e. rainfall and snowfall have increased across the globe.
  4. It has caused many animal species to change their migration patterns. For example, research shows that Icelandic black-tailed godwits birds advanced migration by two weeks over the past two decades.
  5. It has ruptured the fine balance of a healthy ecosystem, where all populations are kept under check. For eg due to the long summer periods in Alaska the Spruce bark beetles, and have destroyed as much as 4 million acres of spruce trees.
