La Niña, we hardly knew ye. This year’s iteration of the climate phenomenon nearly set records for strength and riled up world weather for nine months. Now it’s dead. What’s next?

La Niña Still Hanging On

The current moderate-strength La Niña is now weakening and is expected to dissipate by late spring, said Tony Barnston, the lead forecaster at the International Research Institute for Climate and Society, which holds a monthly climate briefing. Early February showed the first easing in strength of the cool sea-surface temperatures in the central and eastern [...]

Floods in Eastern Sri Lanka and North-Eastern Australia: Contrasts in Disaster Risk Management

by | 2.10.2011 at 3:11pm

Due to the ongoing floods in Sri Lanka, more than a million people are affected, 185,000 were displaced and 16 had died by February 5, 2011. The impact has been most severe on Eastern Sri Lanka a “Disaster Hazard and Vulnerability Hotspot”. The purpose of this post is to publicize information resources to help target disaster risk, and to advocate, before attention turns away, the need to enhance local risk management capacity in manner that pays attention to why lessons are repeatedly identified from major disasters but not followed up on.

El Niño Begins to Dissipate

by | 4.15.2010 at 2:15pm

Though weak El Niño conditions still exist, it appears that the climatic phenomenon that developed over the course of last summer has finally begun to dissipate. As reported earlier, El Niño is the name given to sustained sea surface temperature (SST) anomalies greater than 0.5°C across the central tropical Pacific Ocean. It is the warm [...]

Top misconceptions about El Niño and La Niña

by | 8.7.2009 at 3:02pm

Forecasts by the International Research Institute for Climate and Society and other institutions show that a weak El Niño has developed in the equatorial Pacific, and is likely to continue evolving with warmer-than-normal conditions persisting there until early 2010. What exactly is this important climate phenomenon and why should society care about it? Who will [...]
