State of the Climate in 2023, WMO March 2024: WMO sounded a Red 'Alert on climate change worldwide' Annual report on the state of the global climate, confirms 2023 was the hottest ever recorded for 174 years (by far)
'Records were again broken, and in some cases smashed, for greenhouse gas levels, surface temperatures, ocean heat and acidification, sea level rise, Antarctic Sea ice cover, and glacier retreat'.
The report emphasised that 'warming is expected to continue—a change which is irreversible on scales of hundreds to thousands of years'.

It is clear that the global climate emergency is worse than ever
Global temperature (1) and atmospheric CO2 (2) are increasing
faster than ever (see below)
Yet it is being ignored more than ever

To limit warming to 1.5°C and 2°C
global emissions had to be declining by 2020.
(many references over many years)
The IPCC (6th Assessment) now says global
decline has to be immediate
"2020 to 2025 very latest".

1. Global temperature increasing faster than ever
'Human-induced warming has been increasing at a rate that is unprecedented in the instrumental record, reaching 0.26 [0.2–0.4] °C per decade over 2014–2023'.

2. Atmospheric CO2 increasing faster than ever
During a year of extremes, carbon dioxide levels surge faster than ever
