Why do polar bears depend on ice?
For polar bears, the sea ice is a crucial platform for life. They use the ice to travel long distances to new areas. They hunt for seals by finding their dens or sitting next to gaps in the ice, waiting for the unsuspecting prey to pop up.
What are the effects of polar ice melting?
What are the effects of melting glaciers on sea level rise? Melting glaciers add to rising sea levels, which in turn increases coastal erosion and elevates storm surge as warming air and ocean temperatures create more frequent and intense coastal storms like hurricanes and typhoons.
What are 5 effects of climate change?
What are the effects of climate change and global warming?
- rising maximum temperatures.
- rising minimum temperatures.
- rising sea levels.
- higher ocean temperatures.
- an increase in heavy precipitation (heavy rain and hail)
- shrinking glaciers.
- thawing permafrost.
How long will it take for all the ice to melt?
There are more than five million cubic miles of ice on Earth, and some scientists say it would take more than 5,000 years to melt it all.
