It was recorded by the Spanish conquistadors, and triggered famines that have been linked to China’s 1901 Boxer Rebellion and even the French revolution.
Named by Peruvian fishermen because of its tendency to appear around Christmastime, El Niño is the planet’s most large-scale and recurring mode of climate variability. Every 2-7 years, a slackening of trade winds that push sun-warmed water across the Pacific contributes to a rise in water temperature across large parts of the ocean. As the heat rises, a global pattern of weather changes ensues, triggering heat waves in many tropical regions and extreme drought or rainfall in others.
The fact that we are undergoing a major El Niño event should cause major concern and requires mobilization now. Already, eight provinces in the Philippines are in a state of emergency due to drought; rice farmers in Vietnam and Thailand have left fields unplanted due to weak rains; and 42,000 people have been displaced by floods in Somalia.
And this is before the event reaches its peak. Meteorologists see a 95% chance of the El Niño lasting into 2016, with its most extreme effects arriving between now and March. Coastal regions of Latin America are braced for major floods; India is dealing with a 14% deficit in the recent monsoon rains; and poor rainfalls could add to insecurity in several of Africa’s fragile states. Indeed, Berkeley Professor Soloman Hsiang has used historical data to demonstrate that the likelihood of new conflict outbreaks in tropical regions doubles from 3% to 6% in an El Niño year.
But despite its thousand-year history, the devastation associated with El Niño is not inevitable. Progress made by many other countries since the last major event, in 1997-98, shows that we can get a grip on its effect – and others caused by climate trends.

Pakistan’s unprecedented climate shocks make it clear: regional cooperation for managing shared waters is desperately needed. To halt the increasing impacts on agriculture and livelihoods that cripple the country’s economy, diplomacy is of paramount importance. In our interview, Moeen Khan explains how territorial and ethnic tensions with India hinder much-needed transboundary solutions – and how the international community can help.
Environmental defenders in Brazil are at risk — last year, 57 were assassinated and the numbers are increasing. The UN has launched a new initiative to address the escalating violence. This article shows the challenges faced by an activist from the Amazon region who fights for justice, and it notes how the Brazilian government can save lives while preventing unregulated exploitation in the region.
Changes are occurring that could make climate action a driver of the domestic agenda for economic and social progress and for international cooperation. With the help of market forces and technological advances, the tide is moving toward climate action. Paul Joffe argues that a key to success is a strategy that draws public support and makes climate policy a force in a larger industrial renaissance.
The world can achieve slower climate warming, preventing temperatures from rising by more than 1.5˚C, a global scientific panel says. But time is short.
