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.

Resource consumption has grown exponentially over the past: between 1970 and 2010, the quantity of extracted materials has tripled. Not only the overall amount of resources extracted and consumed has risen rapidly, but also the diversity of resources has grown. While half a century ago, only a few materials such as wood, brick, iron, copper, and plastics were in high demand worldwide, today products are more complex and require a wide range of materials.
Times of war can result in rapid environmental degradation as people struggle to survive and environmental management systems break down resulting in damage to critical ecosystems. For over six decades, armed conflicts have occurred in more than two-thirds of the world’s biodiversity hotspots thus posing critical threats to conservation efforts. [...]
More than 4,700 delegates, including environment ministers, scientists, academics, business leaders and civil society representatives, met in Nairobi for the UN Environment Assembly, the world’s top environmental body whose decisions will set the global agenda, notably ahead of the UN Climate Action Summit in September.
Mid february, the EU's foreign affairs ministers welcomed the Commission’s strategic long-term vision for a climate neutral Europe. Ministers also called for urgent and decisive action to strengthen the global response on climate change and restated the EU’s determination to lead the way on accelerated climate action on all fronts.
