NOAA says La Niña in the Pacific is over

Adios, La Niña by Rebecca Lindsey, NOAA  The La Niña event that overtook the tropical Pacific this past winter is officially over, according to the latest update from NOAA’s Climate Prediction Center. La Niña’s signatureof heavier-than-usual rainfall in the western part of the basin has tapered off, and the cool surface waters in the central part of the basin…

The 60-year oscillation revisited

Guest Post by Javier It is a well-known feature of climate change that since 1850 multiple climate datasets present a ~ 60-year oscillation. I recently wrote about it in the 7th chapter of my Nature Unbound series. This oscillation is present in the Atlantic Multidecadal Oscillation (AMO), Arctic Oscillation (AO), North Atlantic Oscillation (NAO), Pacific…

Finding: North Pacific climate patterns influence El Nino occurrences

From the INSTITUTE OF ATMOSPHERIC PHYSICS, CHINESE ACADEMY OF SCIENCES and the “tail wagging the dog” department. For decades, the world’s leading scientists have observed the phenomena known as El Nino and La Nina. Both significantly impact the global climate and both pose a puzzle to scientists since they’re not completely understood. Now, a new study…

Some overheated rhetoric from Jonathan Overpeck

From the UNIVERSITY OF ARIZONA and the “El Nino is just a heat vent for greenhouse gases” department. Record jump in 2014-2016 global temperatures largest since 1900 Heat generated by greenhouse gas emissions and stored in the Pacific Ocean was released by the 2015-2016 El Niño, University of Arizona geoscientists found. Global surface temperatures surged…

New mechanism for El Nino enhanced storm systems

From the INSTITUTE OF ATMOSPHERIC PHYSICS, CHINESE ACADEMY OF SCIENCES New mechanism to explain how El Niño influences East Asian and WN Pacific climate Western North Pacific anomalous anticyclone (WNPAC, or referred to as Philippine Sea anomalous anticyclone) is the most important anomalous circulation pattern connecting El Niño and East Asian-western North Pacific monsoon. WNPAC begins…

NOAA: La Niña is officially back

November 2017 La Niña update: She’s back! Author:  Emily Becker Well, it’s November, and the CPC/IRI ENSO forecast is declaring the presence of La Niña conditions! I could just link to my November 2016 post and head home for the day… but that would be no fun! There’s about a 65-75% chance that La Niña…

Report: Ocean Cycles, Not Humans, May Be Behind Most Observed Climate Change

An eminent atmospheric scientist says that natural cycles may be largely responsible for climate changes seen in recent decades.  In a new report published by the Global Warming Policy Foundation, Anastasios Tsonis, emeritus distinguished professor of atmospheric sciences at the University of Wisconsin-Milwaukee, describes new and cutting-edge research into natural climatic cycles, including the well known…
