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 […]

March 2014 Climate Briefing: Increasing Odds for El Niño

From the March climate briefing, given by IRI’s Chief Forecaster Tony Barnston: Tony Barnston provides an overview of the briefing Changes from last month’s briefing The IRI’s March ENSO forecast puts the chances of El Niño conditions at 60% for early next fall, an increase from the 45% probability in IRI’s February forecast and  the 52% probability from NOAA/IRI’s official […]

Explainer: The Global Warming ‘Hiatus’

In the March issue of Nature Climate Change, IRI Director Lisa Goddard explains what may be behind the recent slowdown in global temperature growth in a piece titled “Heat Hide and Seek”. The Earth Institute’s Kim Martineau interviewed Goddard for some additional thoughts. We include the original Q&A here along with additional resources. Q: Is there a global warming […]

February 2014 Climate Briefing: Kelvin Waves Signal Potential El Niño

From February’s climate briefing, given by our Tony Barnston: The central and eastern Pacific Ocean is currently experiencing borderline La Niña conditions, but many models are forecasting an El Niño to develop this (northern hemisphere) summer. Although scientists still don’t know the exact mechanism behind the Pacific’s transition from one state of the El Niño […]
