No, they're not exactly the same, but the difference my be a subtle one.
The result of warming is that things get warmer. The impact of warming
is the change that it brings in things that depend on temperature.
Results:
-- The average temperature of the air increases.
-- The average temperature of the oceans increases.
-- The polar ice caps partially or completely melt.
-- The mean sea level rises.
Impacts:
-- Deserts grow in area.
-- Plant and tree species spread farther away from the equator.
-- Some of today's prime farm land becomes barren.
-- The supply of fresh water on Earth is reduced.
-- The average energy in storms is increased.
-- Some of today's coastal land becomes gone.
