কারণ ও প্রেক্ষাপট

Climate change is a long-term statistically significant change in climate means or variability, from natural and human causes. The governing relationship is: Greenhouse-gas emissions alter radiative forcing, warming the climate system and triggering feedbacks in ice, oceans, water and ecosystems.
