 A Chinese labourer stands next t a furnace at outside at an unauthorized steel factory on November 3, 2016 in Inner Mongolia, China. To meet China's targets to slash emissions of carbon dioxide, authorities are pushing to shut down privately owned steel, coal, and other high-polluting factories scattered across rural areas. In many cases, factory owners say they pay informal "fines" to local inspectors and then re-open. The enforcement comes as the future of U.S. support for the 2015 Paris Agreement is in question, leaving China poised as an unlikely leader in the international effort against climate change. U.S. president-elect Donald Trump has sent mixed signals about whether he will withdraw the U.S. from commitments to curb greenhouse gases that, according to scientists, are causing the earth's temperature to rise. Trump once declared that the concept of global warming was "created" by China in order to hurt U.S. manufacturing. China's leadership has stated that any change in U.S. climate policy will not affect its commitment to implement the climate action plan. While the world's biggest polluter, China is also a global leader in establishing renewable energy sources such as wind and solar power. (Photo by Kevin Frayer/Getty Images)

Areial view of the flowermarket at the city market in Bangalore, India  24  November 2016. Indian business is reportedly affected due to lack of Indian currency notes. Indian Prime Minister Narendra Modi announced the elimination of the 500 and 1,000 rupee bills at midnight on 08 November, for the purpose of fighting against 'black money' (hidden assets) and corruption in the country. The decision sparked protests, while storekeepers complained about dwindling sales because many citizens lack the cash to buy the most basic products, as queues get longer at ATMs and banks.

VIBO VALENTIA, ITALY - NOVEMBER 24:  Refugees on the the MOAS vessel "Topaz Responder" as it comes into port on November 24, 2016 in Vibo Valentia, Italy. The MOAS team worked through the night of the 21st and into the next morning rescuing 'approximately' 600 people from several vessels though that figure could change. It is believed that several people had died after one rubber dinghy capsized. 117 people were saved from that incident, but many were left suffering from hypothermia and various other minor injuries. MOAS were patrolling in the 'SAR Search and Rescue Zone, approximate 20KM off the coastline of Libya, and running rescue missions for the many migrants and refugees who continue to attempt to make the dangerous crossing across the Mediterranean Sea to Italy. MOAS are a Malta based registered foundation dedicated to providing professional search-and-rescue assistance to refugees and migrants in distress at sea and work alongside with the Red Cross on board the Topaz Responder. The number of deaths this year of people crossing the Mediterranean has risen to almost 4,300. MOAS alone have rescued around 19,000.  (Photo by Dan Kitwood/Getty Images)
