BBC: Since April an El Niño event has been under way in the Pacific Ocean. El Niños, which are associated with a band of warm water that develops off the western coast of South America, can cause weather events all over the world. Although weak at the moment, the current El Niño is expected to ramp up by September, according to Australia’s Bureau of Meteorology. That could be a cause for concern. Past El Niños have caused monsoons in Southeast Asia; droughts in Australia, the Philippines, and Ecuador; blizzards in the US; heat waves in Brazil; and flooding in Mexico. However, it is still too early to forecast what the effects will be. It has been predicted that future El Niños will cause even more intense weather events as global atmospheric temperatures rise.
