·Climate change
Global warming is causing the temperature of the earth to rise slowly, causing massive global changes to our natural environment.
·Rising sea level
Global warming is rapidly melting glaciers around the globe, causing a rising sea level and possibly coastal flooding and other weather problems in the future.
·Ecosystem changes
Global warming is changing certain ecosystems throughout due to temperature fluctuations (波动). Animals and plants are being forced to adapt to this, and, as a result, are dying off.
·Breakdown of the ozone (臭氧) layer
Global warming is creating holes in the ozone layer, primarily from human use of products that emit (发出) poisonous chemicals. The ozone layer absorbs UV radiation from the sun. The holes are causing amounts of poisonous chemicals present in our breathing air to increase at a rapid rate.
