DIRE PLANETARY EMERGENCY SIGNS
Already committed future warming and climate change
The radiative heat forcing of today's atmospheric GHGs commits the world to a global warming of 1.5°C by 2030-2040 (IPCC AR5 WG1 Figure 11.6) and full equilibrium warming over 2.0°C.
'The current RF(radiative forcing) from GHGs maintained indefinitely (i.e., the commitment from constant greenhouse gas concentrations) would correspond to approximately 2°C warming.'
(IPCC AR5 WG1 18.104.22.168)

We keep a comprehensive record of climate change indicators, from the climate monitoring centers such as NASA and NOAA (in the U.S.). This covers changes the entire climate system, which is essential for climate change risk and future impact assessment, mitigation and adaptation planning.
The change is actually climate system change and we monitor all climate system change indicators.
All indicators are record high, increasing at record rates (May 2023).
Global CO2 emissions were a new all-time
high in 2022, with no plans to change fossil fuel energy dominance, which means life will get harsher everywhere, leading an unliveable planet.
Atmospheric CO2 is at 4 million year high increasing fastest in past 50 million years.
Atmospheric methane has increase 260% and explosively since 2019 (die to wetland feedback emissions.
Northern hemisphere temperature is increasing at an accelerating rate since 2000, far faster than the global average.
The oceans, by far the largest and most crucial climate system component, are being heated, acidified and deoxygenated at an accelerating rate.
The climate system (and planet) is in a no-analog state, never experienced by advanced life before.
