KATHMANDU - Nepal is stepping up calls for major greenhouse gas emitters to take action against climate change after devastating floods triggered by what is believed to have been a glacier collapse linked to global warming struck the Himalayan nation in August.

Prime Minister Balendra Shah, a former rapper who took office in March, appealed for international solidarity at the U.N. General Assembly in September, warning that Nepal was paying a heavy price for climate change despite contributing little to global greenhouse gas emissions.
