How much has the amount of CO2 in the atmosphere changed in history?
The figure below show results of CO2 measurements of air trapped in
ice cores taken at the Law Dome site in Antarctica, along with
present day measurements at the CMDL Mauna Loa Observatory in
Hawaii. CO2 amounts have increased about 35% in the last 200 years.
El Nino is a natural phenomenon that has been occurring throughout
the centuries, though not always with the same regularity; it now
occurs about every two to seven years. El Nino is the strong warming
of the equatorial Pacific ocean. Its effects are felt worldwide,
which demonstrates the interconnected nature of the Earth's
climate. ... Scientists are concerned that the accumulation of
greenhouse gases in our atmosphere may inject enough heat into
the Pacific Ocean to make El NiÃ±o events more frequent and fierce.
