Weather in Context: Weird Winter or Standard Season?
It’s nearly impossible to pinpoint a particular weather event as caused or made worse by climate change, but during any prolonged duration of exceptional weather, such questions always arise. We want to know if the weather we’re experiencing is actually unusual, if it’s part of larger climatic change and if it’s going to become more […]

Climate prediction tools show role of oceans in Amazon drought and fire season
In the last decade, warmer sea surface temperatures in the tropical Atlantic have corresponded with below-average precipitation in Peru and western Brazil. The relationship is due to the effect of sea surface temperatures on the location of the Inter-tropical Convergence Zone (ITCZ) – a band of clouds and rain stretching around the globe where trade winds […]

Chasing Tornadoes: A Close Call with a Deadly Storm
By John Allen I’ve been chasing storms in the Great Plains of the United States since 2010, and before that in Australia since 2003. My interest in meteorology started from an encounter with a hailstorm in Sydney, Australia back in 1990, and since then I have had an avid interest in storms that has led […]

Managing Water in a Dry Land
The Elqui River basin in Chile’s Coquimbo region is one of the driest places on Earth. It receives only about 100 millimeters (4 inches) of rain each year, and most of it during one short rainy season. The rainfall isalso highly variable. In some years, the region will get close to zero rainfall, while in […]

Are We Entering an Age of Mega-Fires?
For millennia, people have set fires to clear land for cultivation, pastures or hunting; so-called slash-and-burn agriculture is still common across much of tropical Africa, Asia and South America. It has been a useful strategy, but it is now becoming problematic. A new Earth Institute story and documentary, shot in the Peruvian Amazon, follows the […]

Health Risks From Famine Likely to Persist
In a video interview about the East Africa famine, IRI’s Madeleine Thomson, an expert in climate and public health, says the health consequences of the famine will be felt not only in the short term, but for years and decades to come: We know from the 1984 Ethiopia famine that the impacts are intergenerational. They […]
The Role of Drought in the Horn of Africa Famine
Let’s get this out of the way. The current famine in the Horn of Africa isn’t caused by drought. Rather, a complex mix of societal and political factors created a dangerous situation.The worst drought in 60 years is what pushed that situation over the edge into a humanitarian crisis. However, just as these social factors were […]
Climate Information Crucial to Help Reduce Risk and Limit Disaster Damage
Forecasts can play an invaluable role when used properly in helping humanitarian agencies and governments plan for and prevent disasters, according to the latest Climate and Society publication launched by the IRI and the American Red Cross last week in Washington D.C.

To Burn, or Not to Burn
Imagine smoke and haze so thick it causes ships to crash into each other, shuts down airports and sends millions of people to the hospital with respiratory problems. This was the scene in Southeast Asia in 1997 and 1998, when land-clearing fires set by massive palm oil plantations and small scale farmers burned out of […]
La Niña Related Impacts Likely to Continue
As of mid-January, moderate-to-strong La Niña conditions continue to exist in the tropical Pacific. Scientists at the International Research Institute for Climate and Society expect these to linger, potentially causing additional shifts in rainfall patterns across many parts of the world in months to come. These shifts, combined with socioeconomic conditions and other factors, can […]

Managing Risk in a Changing Climate: Making the Case

Increasingly, the question of whether or not climate […]

Climate Information Helps Prepare for Disasters
Climate-related disasters can have a devastating impact on human life and development. Globally, climate events including floods, droughts, cyclones, heat waves and mudslides contribute to tens of thousands of deaths, hundreds of thousands of injuries and billions of dollars in economic losses each year. In recent years, it’s become clear that such losses can be […]
