Abstract:
OSTST community feeds climate community with altimetry data of increasing quality. Number of missions and observations increase, uncertainties are better characterized and historical missions are reprocessed to benefit from recent standards.
Among the users, the IPCC (International Panel on Climate Change) is about to close its sixth assessment cycle, in which the IPCC have produced the Sixth Assessment Report (AR6) with contributions from its three Working Groups, three Special Reports, and a Synthesis Report. In particular, the Working Group I report addresses the most updated physical understanding of the climate system and climate change. Several levels of global warming with an increasing level of casualties and lethality for the terrestrial ecosystem are detailed.
One key feature of this report is the notion of remaining carbon budget, used to describe the total net amount of CO2 that remains to be released in the future by human activities before reaching a specific global warming level.
In this presentation we consider the IPCC value of remaining carbon budget, and we convert it into remaining emissive years to understand the climate timescale . We analyze typical carbon footprint and deduce some of the most efficient actions that could be taken at individual and collective level.
We open a reflection on the balance between OSTST responsibility to maintain performing science and its responsibility to control its Greenhouse Gazes emissions
