Climate Crisis Likely to Intensify El Niño, Pushing Global Temperatures Past 1.5°C Threshold
"It's the first time in history that it's more likely than not that we will exceed 1.5°C," said a co-author of a new U.N. report.
May 17, 2023
Naturally-occurring El Niño events have resulted in hotter global temperatures for thousands of years, but a United Nations agency warned Tuesday that the warming trend that scientists expect to form in the coming months will be intensified by heat-trapping greenhouse gas emissions—likely resulting in an average global temperature that's more than 1.5°C above pre-industrial levels for at least a year.
"A warming El Niño is expected to develop in the coming months and this will combine with human-induced climate change to push global temperatures into uncharted territory," said Prof. Petteri Taalas, secretary-general of the World Meteorological Organization (WMO), as the agency released its Global Annual to Decadal Climate Update ahead of the El Niño Southern Oscillation (ENSO) event.
A global average temperature that exceeds 1.5°C above pre-industrial levels would mean that the planet temporarily grows hotter than the limit specified by the Paris climate agreement.
The WMO report says there is a 66% chance that the annual average global temperature will exceed 1.5°C above pre-industrial levels for at least one year between 2023 and 2027.
"It's the first time in history that it's more likely than not that we will exceed 1.5°C," Adam Scaife of the U.K.'s Met Office, who worked on the report, told Reuters.
As Common Dreams reported Monday, climate scientists are currently observing trends in the Pacific Ocean that appear "very much like the 1997 and 2015 early stages of a Super El Niño," in which very high temperatures would be recorded near the equator.
El Niño events occur roughly every five years, and the one that appears to be forming now is likely to make at least one of the next five years the warmest on record. The El Niño event that occurred in 2016 contributed to 2016, 2019, and 2020 being the hottest years on record so far.
The WMO report said there is a 98% chance that the upcoming five-year period as a whole will be the warmest in recorded history. There is a 32% likelihood that the five-year mean temperature will exceed the 1.5°C threshold.
Although the breach of the 1.5°C limit is expected to be temporary, Taalas warned that this El Niño event could signal a new pattern.
"This report does not mean that we will permanently exceed the 1.5°C level specified in the Paris Agreement which refers to long-term warming over many years. However, WMO is sounding the alarm that we will breach the 1.5°C level on a temporary basis with increasing frequency,” said Taalas. "This will have far-reaching repercussions for health, food security, water management, and the environment. We need to be prepared."
Scientists and heat experts have begun calling on officials to prepare communities with cooling stations, access to air conditioning equipment, and other measures to cope with the hot weather El Niño is expected to bring.
Prior to 2015, the chance of the annual global average temperature crossing the 1.5°C threshold was "close to zero," according to the WMO. Between 2017 and 2021, scientists recorded a 10% chance.
"Global mean temperatures are predicted to continue increasing, moving us away further and further away from the climate we are used to," said Dr. Leon Hermanson, a Met Office scientist who led the report.
The report noted that warming in the Arctic is "disproportionately high," which has threatened the collapse of a crucial ocean current system and disrupted weather patterns in the northern hemisphere.
Climate writer Andy Rowell called the WMO's report both "heartbreakingly terrifying and predictable" as the fossil fuel industry and policymakers refuse to heed the warnings of scientists and energy experts, who say the continued extraction of oil and gas have no place on a pathway to avoiding the 1.5°C warming limit.
"This report must be a rallying cry to intensify global efforts to tackle the climate crisis," Doug Parr, chief scientist at Greenpeace U.K., told Reuters.
An Urgent Message From Our Co-Founder
Dear Common Dreams reader, It’s been nearly 30 years since I co-founded Common Dreams with my late wife, Lina Newhouser. We had the radical notion that journalism should serve the public good, not corporate profits. It was clear to us from the outset what it would take to build such a project. No paid advertisements. No corporate sponsors. No millionaire publisher telling us what to think or do. Many people said we wouldn't last a year, but we proved those doubters wrong. Together with a tremendous team of journalists and dedicated staff, we built an independent media outlet free from the constraints of profits and corporate control. Our mission has always been simple: To inform. To inspire. To ignite change for the common good. Building Common Dreams was not easy. Our survival was never guaranteed. When you take on the most powerful forces—Wall Street greed, fossil fuel industry destruction, Big Tech lobbyists, and uber-rich oligarchs who have spent billions upon billions rigging the economy and democracy in their favor—the only bulwark you have is supporters who believe in your work. But here’s the urgent message from me today. It's never been this bad out there. And it's never been this hard to keep us going. At the very moment Common Dreams is most needed, the threats we face are intensifying. We need your support now more than ever. We don't accept corporate advertising and never will. We don't have a paywall because we don't think people should be blocked from critical news based on their ability to pay. Everything we do is funded by the donations of readers like you. When everyone does the little they can afford, we are strong. But if that support retreats or dries up, so do we. Will you donate now to make sure Common Dreams not only survives but thrives? —Craig Brown, Co-founder |
