What does the future hold?
On average, global temperatures increased
by 0.6°C during the 20th century. Most of
the warming happened in the last 50 years.
Scientists on the Intergovernmental Panel
on Climate Change (IPCC) tell us that much
of this warming is due to greenhouse gases
produced by human activities. The future is
hard to predict? We are unsure about how
the atmosphere works and do not really
know how humans will behave. Will we
continue to use the world in the same way?
Will the human population double by the
year 2020? |
