How does global warming affect nature?

Answer 1

Changes in climate (warmer/colder, wetter/drier) affect the ecologies present in an area. Climate change (sometimes simplistically called global warming) can induce all of these impacts. As a result the plants which grow in areas both wild and crops will change,, the animals supported by the plants will change, and human populations will have to adjust. As examples:

• droughts will turn some presently productive areas into barren deserts. For humnas this will mean no water supply for major cities.
  
• changes in warm spring wether will have food supplies for returning migratory birs out of phase with their breeding and nesting need
  
• invasive species will overcome present fish and animals - this includes insects
  
• many fish need cool water for breeding and this may change
  
• flooding with increased rainfall will alter the course of rivers
• many animals have migration routes requiring specific weather timing, these animals will not survive
• feeding and breeding grounds for arctic animals will vanish
• lowlands will flood with increased ocean levels which will destroy many low lying ecosystems

Answer 2

Global warming can lead to changes in ecosystems and habitats, disrupting the natural balance and driving certain species to extinction. It can also cause extreme weather events like heatwaves, droughts, and storms which further impact wildlife and their food sources. Rising temperatures can also alter migration patterns and breeding seasons of animals.
