SANTIAGO, March 22 (Xinhua) -- Former Chilean President Ricardo Lagos joined members of the Socialist International Commission for a Sustainable World Society and some scientists in traveling to the Antarctica to probe global warming on Saturday.

    The group was launching a visit to Chile's Eduardo Frei Base in Antarctica, which is aimed at researching the ecological and environmental impacts of global warming, Lagos told reporters ahead of the Antarctica tour.

    Lagos called on the international community to take effective measures to fight global warming, which is seen as a mission impossible for every country to accomplish alone.

    The Socialist International is the worldwide organization of social democratic, socialist and labor parties. The Socialist International Commission for a Sustainable World Society, scheduled to meet on Monday in Santiago, is expected to advance the body's work on the global environmental agenda.

    Lagos is co-chairman of the commission. He was appointed in May2007 as the U.N. Secretary General's special envoy on Climate Change.
