Global emissions had to decline with 'immediate action' by 2025 for the 1.5°C AND 2°C limits (way too late now for 1.5°C))
(IPCC 6th Assessment, WG3, SPM C.1)
Climate Emergency Institute
2024 was the global warming record year at 1.55°C and 2025 was 1.44°C (WMO)
ATMOSPHERIC GREENHOUSE GAS CONCENTRATION
Atmospheric greenhouse gas concentration (CO2 equivalent) drives global warming, not CO2 alone.
It is increasing, at a record high of 539 ppm CO2eq. in 2024, and it is accelerating (NOAA AGGI) Atmospheric CO2 is accelerating, and has been since start of monitoring in 1958
It reached an annual record high of 427.35 ppm in 2025 (NOAA)
Mitigation
For the 1.5°C and the 2°C limit global GHG emissions had to peak and decline by 2025
This not being recommended (apart from the IPCC Assessment).
GLOBAL GHG EMISSIONS
2024 global GHG emissions are still increasing (being increased) and reached a record 53.2 Gt CO2eq.
(EDGAR, 2025)
Emissions show acceleration in the long and short term.
Instead, they are still being increased, as fast as ever, which means future planetary catastrophe.

Global warming - is being acclerated
The 1.5°C globally disastrous danger limit has been reached,
and the temperature increase will definitely go higher, as GHG emissions and atmospheric concentrations are record high, increasing fast as ever (below).
THE CLIMATE EMERGENCY IS MOST DIRE -- BUT BEING IGNORED
Global greenhouse gas emissions is used by the IPCC
for assessment and mitigation, not CO2 alone
