Global climate is projected to continue to change over this century and beyond. The magnitude of climate change beyond the next few decades depends primarily on the amount of heat-trapping gases emitted globally, and how sensitive the Earth’s climate is to those emissions.
Effects that scientists had predicted in the past would result from global climate change are now occurring: loss of sea ice, accelerated sea level rise and longer, more intense heat waves.
According to a United Nations report released Tuesday, however, projected emissions of carbon dioxide, the primary greenhouse gas, from nations around the world fall woefully short of the 2 degree Celsius goal set in the Paris Climate Agreement in 2015.
the current emission targets for all countries would result in an average global temperature rise of 3.2 degrees Celsius (5.8 degrees Fahrenheit) by 2100.
the extent of climate change effects on individual regions will vary over time and with the ability of different societal and environmental systems to mitigate or adapt to change.
The United States is the only country which would be missing from the Paris Climate Agreement thanks to president trump who has dismissed the US out of the pact claiming it placed "draconian" financial burdens on the American people.
