The State of the Climate 2023 (GWPF) – evidence of crisis not observed

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.”
