Global Warming Research - Do You Recognize the 3 major goals for global warming research

Global warming research has been divided into 3 major goals

Global warming research concluded rapid increase in the consumption of fossil fuels, level of carbon dioxide in the atmosphere has been steadily increasing. Many great scientist have projected that if greenhouse gases doesn't stopped from increasing in the atmosphere, than it could effect negatively on and it is very critical suitation now to investigate about this important problem. Concerned orgatnisation must do something on this and should provide reliable assessment of current and future changes in global climate.


As this global warming research have many different goal to achieve but one of the main goal is to provide reliable and quantitative projection of global warming.





Let's divide global warming research into three different goal to make it simple for you:

First gloal(G1) is to reduce the uncertainty while determining the appropriate response of climate changes in real time (which could help the concerned localities to intimate from calamities) concentration of greenhouse gases and aerosols in theatmosphere, elucidating the physical mechanism of global warming.


Second gloal(G2) is to develop model for an atmosphere-ocean-land coupled which have high performance through numerical experiments and comparison of the outputs with the observed analyses.


Third Goal(G3) is to get detailed information about the chemical and physical mechanisms, which are responsible for the large climactic change of the geological past.


It also attempts to evaluate and validate the sensitivity of model climate through paleoclimate simulations. The primary tools of these groups are general circulation models of both the atmosphere and ocean and the coupled atmosphere-ocean-land models.

This group explores the physical mechanism of future changes of weather and climate, which occur in response to the increase of greenhouse gases in the atmosphere. It will thus contribute to the reduction of the uncertainty in projections of these changes. Specifically, the project will investigate how the behavior of tropical and extra-tropical cyclones, monsoon, and the baiu front, which have substantial impacts on the Asian climate, are influenced by the climate change with a high-resolution climate model. The response of cloud distribution and thickness to the climate change, which affects strongly the amplitude of the future warming, will be examined with a climate model and observational data analysis. The possibility of weakening of the Atlantic deep ocean circulation in response to the climate change will also be investigated.


These studies are conducted as joint projects with the Center for Climate System Research of the University of Tokyo (CCSR) and the National Institute for Environmental Studies (NIES) and with the Meteorological Research Institute (MRI).

Coupled Model Development Group [Second gloal(G2)]

One of the main goals of FRCGC is the development of a coupled atmosphere-ocean-land model which can reproduce climate variability at various time scales. Cooperation between specialists in each research field related to the climate system is essential to further understanding of the various physical mechanisms involved in climate change, and to ensure that each process is accurately represented in the model. The coupled model development group has been formed within the Global Warming Research Program so that it works as the central core team in the coupled model development. Our group will collaborate closely with researchers in related organizations outside FRCGC, as well as with other members of the Global Warming Research Program and FRCGC, with the aim of developing the best model to date. The coupled model will be open for use by researchers inside and outside FRCGC under a certain guideline of usage.

Paleoclimate Research Group [Third gloal(G3)]

Using a hierarchy of climate models with varying degrees of complexity, this project will explore the physical and chemical processes that control past changes of climate, ice sheet extent and oceanic circulation. It also validates climate models based upon the simulation of the climates of geological past such as the last glacial maximum and the late Cretaceous period.


The emphasis of this project is also on the quantitative assessment of the astronomical theory of glacial/interglacial fluctuation of global climate during the Quaternary. Using coupled or uncoupled ocean-atmosphere-continental ice sheet models of varying degrees of complexity, this project inquires why the changes of Earthеs orbit around the Sun had an enormous impact upon the fluctuation of ice volume and global climate. In addition, this project will attempt to project future changes in Greenland and Antarctic ice sheets associated with global warming.


These studies are conducted in close collaboration with the Center for Climate System Research (CCSR) of the University of Tokyo.
