ABSTRACT: The study of dynamic relationships between
the atmospheric carbon dioxide and the Earth’s global temperature in the
current changing climate supported the notion that the trend in the global
temperature followed the trend in the atmospheric CO2 before the climate hiatus
that started in the beginning of the 21st century. During the hiatus period,
the heat trapped by the atmospheric CO2 is going mostly to the ocean. This
conclusion is supported by comparison of the CO2 trend with the trend in the
ocean heat content. The phase relationships between the CO2 and temperature are
more complicated after the removal of the trends. The phase relationships are
chaotic on time scales shorter than the annual time scale. During 1986-2008,
the atmospheric CO2 changed in an-ti-phase with the global temperature. The
phase relationship reversed in 1979 and after 2010. The atmospheric CO2 was
in-phase with the global temperature on the El Nino time scale (2.3 - 7 years)
except during very strong El Nino years in 1991-1999 when CO2 led the global
temperature.
