Abstract
This paper presents an emerging direction of systems thinking, transdisiciplinary science and technology, that is expected to respond to critical issues such as environmental sustainability in our knowledge based information society. Firstly today's systems analysis to global warming is presented for reviewing current systems approaches, then some hypothetical requisites for the further advancements are investigated with historical consideration on systems thinking. Finally present efforts for developing transdisciplinary science and technology are presented to meet the societal requirements.
