Q. The Mangistau region, recently in the news for a man-made methane leak, is located in which country?
Answer:
Kazakhstan
Notes: Last year in Kazakhstan's Mangistau region, a drilling incident resulted in one of the largest man-made methane leaks ever, possibly the second biggest. The fire caused by the incident raged for six months, releasing 127,000 tonnes of methane. Plumes of gas were visible from space, detected 115 times by satellite instruments. Methane, a potent greenhouse gas, contributes to global warming. Fossil fuel operations are responsible for 40% of human-caused methane emissions. The leak, now stopped, had an "unusual" and "extremely big" impact, according to the UN.
