El Niño returns and there could be record temperatures in 2023

The world can Breaking the new average temperature record in 2023 or 2024Driven by climate change and the early return of El Niño weather events, climate scientists say.

Climate models suggest that after three years of La Niña in the Pacific, which usually lowers global temperatures slightly, the world will experience another El Niño, its warmer counterpart, later this year.

During El Niu, winds blowing west along the equator slow and warm water is pushed eastward, warming the ocean surface.

“Neo is often associated with record-breaking global temperatures. Whether this will happen in 2023 or 2024 is not yet known, said Carlo Bontempo, director of the Climate Change Service for the European Union’s Copernicus Programme.

“Climate models indicate a return to neo conditions in late summer and the possibility of major neo development by the end of the year,” Bontempo said.

2016 was the hottest year on record in the world so farwhich coincided with a strong El Niño, although climate change has led to higher temperatures even in years without it.

The past eight years were the hottest on record in the world, reversing a long-term warming trend caused by greenhouse gas emissions.

Temperatures caused by El Niño may exacerbate the effects of climate change that countries are already experiencing, such as heat waves, droughts and fires, says Frederic Otto, a professor at the Grantham Institute at Imperial College London.

“If El Niño develops, it is very likely that 2023 will be hotter than 2016, given that the world continues to warm while humans continue to burn fossil fuels,” Otto said.

Scientists from the Copernicus Program Climate Change Service published a report Thursday assessing the extreme weather events the world witnessed last year, the fifth-highest ever recorded.

Europe experienced its hottest summer on record in 2022, while heavy rainfall caused by climate change caused catastrophic flooding in Pakistan, and Antarctic sea ice levels hit a record low in February.

According to the Copernicus team, the global average temperature is now 1.2 degrees Celsius higher than it was in pre-industrial times.

Despite a commitment by most of the world’s major emitters to reduce their net emissions to zero, global carbon dioxide emissions continued to rise last year.
