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 over 1.5°C by 2030-2040 (IPCC AR5 WG1 Figure 11.6). With no action on emissions 2°C will be by 2050.
'The current (2014) 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 220.127.116.11)

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 (Dec. 2023). Global CO2 emissions were a new all-timehigh in 2023. With no action or plans to change fossil fuel energy dominance, life will get harsher everywhere, leading an unliveable planet.Atmospheric CO2 (most of heating, all ocean acidification) is at a 14 million year high increasing fastest in past 50 million years.Atmospheric methane has increase 266% and explosively since 2019 (due 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, all at an accelerating rate. The climate system (and planet) is in a no-analog state, never experienced by advanced life before.
