Global emissions had to decline with Immediate actionby 2025 for 1.5°C AND 2°C limits (1.5°C now way too late)
(IPCC 6th Assessment, WG3, SPM C.1)
Climate Emergency Institute
2024 was the global warming record year at 1.55°C and 2025 was 1.47°C (Copernicus)
ATMOSPHERIC GREENHOUSE GAS CONCENTRATION
Atmospheric greenhouse gas concentration (CO2 equivalant) drives global warming, again not CO2 alone.
It is increasing, at record high at 539 ppm CO2eq. in 20204, and it is accelerating (NOAA AGGI) Atmospheric CO2 is accelerating, and has been since start of monitoring in 1958
It has reached a record high of 428.7 ppm (April 2026)
Mitigation
IPCC AR6: For the 1.5°C limit and for the 2°C limit global GHG emissions decline by 2025 at the latest, with immediate action.
This not being recommended.
There are no global mitigation proposals, to even reduce fossil fuel CO2 emissions
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.

Below is climate change in a nutshell (brief)
Global warming - is being acclerated
The 1.5°C globally disastrous danger limit has been reached,
and the temperature increase will definitely go higher
GLOBAL WARMING (2025)
THE CLIMATE EMERGENCY IS MOST DIRE -- BEING IGNORED
Global greenhouse gas emissions is used by the IPCC for assessment and mitigation, not CO2 alone
