Where is global warming in relation to the long-term temperature goal?
Friday, 1st December 2023
Aims:
To interpret 2023’s extreme temperatures in the context of the Paris Agreement, including for the science community to understand how the Paris Agreement long-term temperature goal (LTTG) is interpreted and used in UNFCCC negotiations; and for the policy-making community (to understand how the chosen definition of temperature change affect the quantification of global warming to date) Also, how to track these and other indicators of climate change between IPCC report cycles.
Narrative
2023 has broken global temperature records, but will such records continue to fall, and if so what are the longer-term implications? Over the next decade, global greenhouse gas emissions might be expected to peak and start to decline, but global temperatures can still be expected to breach 1.5°C of warming above their pre-industrial level with increasing frequency. With around 7 years until the next IPCC Assessment Report is expected, how can the UNFCCC and other stakeholders best access, incorporate and utilise trusted information on climate trends, to better understand and make assessments of where we are in terms of the Paris Agreement long-term temperature goal (LTTG)? And how can climate scientists support them in doing so?
