 The paper discusses the correlation between global temperature and sea level, and how keeping shorelines near their present location requires keeping global temperature within or close to its pre-industrial Holocene range. However, global temperature now exceeds plus 1°C relative to the 1880-1920 mean, and Earth is as warm as it was during the prior. Emion, interglacial period when sea level reached 6 to 9 am higher than today. The paper also shows that Earth is out of energy balance with present atmospheric composition, implying that more warming is in the pipeline. The growth rate of greenhouse gas climate forcing has accelerated markedly in the past decade, and targets for limiting global warming now require negative emissions, or extraction of CO2 from the air. If phased down of fossil fuel emissions begin soon, improved agricultural and forestry practices may provide much of the necessary CO2 extraction. However, continued high fossil fuel emissions today place a burden on young people to undertake massive technological CO2 extraction if they are to limit climate change and its consequences. Proposed methods of extraction such as BCCS or air capture of CO2 have minimal estimated costs, but also have large risks and uncertain feasibility. This article was authored by J. Hansen, M.
