Explanation:
How much will the Earth's surface warm up over the lives of our children?
No
one is sure.
Compared to the past 100 million years, the Earth is currently enduring a
relative cold spell,
possibly about four degrees Celsius below average.
Over the past 100 years, however, data indicate the
average global temperature of the Earth has increased by nearly one degree Celsius.
Few disagree that recent
global warming is occurring, and the
Intergovernmental Panel on Climate Change
(IPCC) has
concluded
that we humans have created a warming surge that is likely to continue.
A future temperature increase like that shown on the
above predictive map may cause
sea levels to rise,
precipitation patterns to change, and much
pole ice to melt.
The result could
impact many local agricultures and the
global economy.
Geoengineering projects
that might include
artificial cloud creation might reduce the amount of warming sunlight that reaches
the
Earth's surface.
