El Niño is Coming This Winter. The Question is, Will It Be a Whopper?

San Diego County’s fragile shoreline and vulnerable beachfront properties could be in for a rough winter, according to the California Coastal Commission, the National Weather Service and some top San Diego scientists.

“We are looking at an emerging El Niño event,” staff geologist Joseph Street told the Coastal Commission at its meeting Wednesday in Eureka.

World Hits Record Land, Sea Temperatures as Climate Change Fuels 2023 Extremes

The target of keeping long-term global warming within 2.7 Fahrenheit is moving out of reach, climate experts say, with nations failing to set more ambitious goals despite months of record-breaking heat on land and sea.

As envoys gathered in Bonn in early June to prepare for this year’s annual climate talks in November, average global surface air temperatures were more than 2.7F above pre-industrial levels for several days, the EU-funded Copernicus Climate Change Service said.

Though mean temperatures had temporarily breached the 2.7F threshold before, this was the first time they had done so in the northern hemisphere summer that starts on June 1. Sea temperatures also broke April and May records.

“We’ve run out of time because change takes time,” said Sarah Perkins-Kirkpatrick, a climatologist at Australia’s University of New South Wales.

Ocean Temperatures Are Off the Charts, and El Niño is Only Partly to Blame

In a world of worsening climate extremes, a single red line has caught many people’s attention.

The line, which charts sea surface temperatures in the North Atlantic Ocean, went viral over the weekend for its startling display of unprecedented warming — nearly 2 degrees (1.09 Celsius) above the mean dating back to 1982, the earliest year with comparable data.

El Niño is Coming, and Ocean Temps Are Already at Record Highs – That Can Spell Disaster for Fish and Corals

It’s coming. Winds are weakening along the equatorial Pacific Ocean. Heat is building beneath the ocean surface. By July, most forecast models agree that the climate system’s biggest player – El Niño – will return for the first time in nearly four years.

El Niño is one side of the climatic coin called the El Niño-Southern Oscillation, or ENSO. It’s the heads to La Niña’s tails.

What is El Niño and How Does It Affect the Weather?

A major key to shaping weather patterns worldwide is found in the tropical Pacific Ocean, far from any mainland. Known as the El Niño-Southern Oscillation, this climate phenomenon is the pattern that can create significant differences in average ocean temperatures and often plays a pivotal role in how global weather patterns unfold.

2019 Was A Record Year For Ocean Temperatures, Data Show

Last year was the warmest year on record for the world’s oceans, part of a long-term warming trend, according to a study released Monday.

“If you look at the ocean heat content, 2019 is by far the hottest, 2018 is second, 2017 is third, 2015 is fourth, and then 2016 is fifth,” said Kevin E. Trenberth, a senior scientist at the National Center for Atmospheric Research and an author on the study
