The article discusses the study which analyzes the metrics for comparing greenhouse gases with the integrated temperature change potential (IGTP). The study showed that IGTP and the global warming potential (GWP) are equal when the time horizon approaches infinity. The study used a diffusion energy balance with climate sensitivity assumptions to estimate the greenhouse gases difference between IGTP and GWP. Results show that GWP and IGTP are differed by 10% for methane (CH4).

    A photoreduction of CO2 gas catalyzed by TiO2 powder has been studied with purpose to form methane and/or methanol as well as to prevent global warming. The photoreduction was carried out in a batch horizontal column that is by irradiating a mixture of CO2 with water vapor in the presence of...

    Most present-generation climate models simulate an increase in global-mean surface temperature (GMST) since 1998, whereas observations suggest a warming hiatus. It is unclear to what extent this mismatch is caused by incorrect model forcing, by incorrect model response to forcing or by random...

    We have recently suggested that the warming in the sea surface temperature (SST) since 1900, did not occur smoothly and slowly, but with two rapid shifts in 1925/1926 and 1987/1988, which are more obvious over the tropics and the northern midlatitudes. Apart from these shifts, most of the...
