3. TASK FORCE ON HEMISPHERIC TRANSPORT We have now begun to look even further across the whole northern hemisphere, even the globe But we are still at the position of establishing the scientific basis of the problem The Task Force is thus a scientific body But it will address questions that are ultimately relevant to policy makers We have now begun to look even further across the whole northern hemisphere, even the globe But we are still at the position of establishing the scientific basis of the problem The Task Force is thus a scientific body But it will address questions that are ultimately relevant to policy makers UNITED NATIONS ECONOMIC COMMISSION FOR EUROPE
