The summary remarks: ‘There is no visible effect of the global COVID-19 lockdown 2020–2021 in the atmospheric concentration. The increasing amount of atmospheric carbon dioxide is enhancing photosynthesis and thereby global crop yields.’

London, 28 March — In his annual review of the state of the global climate, Professor Ole Humlum reviews last year’s key data and observations in the context of long-term climate trends, says the GWPF.
The review covers a wide range of temperature measurements in both ocean and atmosphere, alongside reviews of oceanic oscillations, sea level, snow and ice measurements and storms.
Professor Humlum draws attention to two oceanographic events that are likely to have driven up global temperatures in 2023:
While global average surface air temperatures in 2023 were at record highs relative to long instrumental records (since 1850), they were driven up as a result of the still ongoing El Niño warming episode. In contrast, the two previous years, 2021 and 2022, were influenced by a cold La Niña in the Pacific Ocean. Thus the global surface air temperature record in 2023 continues to be significantly influenced by oceanographic phenomena.”
The influence of the Hunga Tonga-Hunga Ha’apai eruption on 2023 meteorological conditions is still uncertain. The eruption, which occurred in the southern Pacific Ocean in January 2022, released an enormous plume of water vapour into the Stratosphere, but there is still uncertainty whether this event had any influence on atmospheric temperatures.
Professor Humlum said:
The global climate system represents a multifaceted system, involving sun, planets, atmosphere, oceans, land, geological processes, biological life, and complex interactions between them. Many components and their mutual coupling are still not fully understood or perhaps not even recognised.
Believing that one minor constituent of the atmosphere (CO2) controls nearly all aspects of climate is naïve and entirely unrealistic.”

WMO: El Niño/La Niña Update (February 2024)
05 March 2024
The 2023-24 El Niño has peaked during November-January and is now gradually weakening. WMO Global Producing Centres of Long-Range Forecasts indicate around a 60% chance of El Niño conditions persisting during March-May 2024, and around a 40% chance of transitioning to ENSO-neutral conditions during March-May. El Niño conditions then become increasingly unlikely, and there is around 80% chance of ENSO-neutral conditions for April-June. A possible transition from ENSO-neutral to La Niña during June-August is suggested by some climate models, while the chance of El Niño persisting during June-August is low (around 10%). Due to the relatively low historical performance of long-range forecast models at this time of year, commonly known as the Northern Hemisphere “spring predictability barrier”, these ENSO forecasts should be interpreted with caution.

Thanks for the news about this report. I did a synopsis based on the 10 key findings and supporting images.

In Ron C’s post, item 6 shows the blue and red (NH and SH) lines crossing at about solar max in Nov. 2001. Hard to say if that was a coincidence but might be worth keeping an eye on.
There’s a bit of a crisis of confidence in climate science circles.
‘Humbling, and a bit worrying’: Researcher claims that models fail to fully explain record global heat – 1 April 2024
The 2016 temperature spike came on the heels of an El Niño event, with the biggest anomalies in February, March and April of the year following its peak, he said. He noted that similar patterns occurred after previous El Niños in 1998 and 1942.
Conversely, last year’s spike arrived in August, September, October and November—before the peak of El Niño—”and that has never happened before,” Schmidt said. “It never happened in the temperature record that we have. It doesn’t happen in the climate models.”
. . .
In his Nature article, Schmidt said the inexplicable elements of the recent warming have revealed an “unprecedented knowledge gap” in today’s climate monitoring, which drives home the need for more nimble data collection that can keep up with the pace of change.
He noted it may take researchers months or even years to unpack all the factors that could have played a part in the sizzling conditions.
“We need answers for why 2023 turned out to be the warmest year in possibly the past 100,000 years,” he wrote. “And we need them quickly.”

Hang on, it can’t be more than two or three months ago all these all-seeing all-knowing ultra-wise “climate scientists” were solemnly assuring us that “the science was settled” and there was “a consensus” and assorted other certainties.
