Abstract:
\n
Our carbon emis sions are driving unprecedented increases in global temperatures\, and onl y their complete elimination will preserve a livable climate in the long t erm. Recent comprehensive assessments show that large-scale mitigation eff orts are falling short: even optimistic emissions-reduction scenarios are projected to exceed the Paris Agreement's 1.5–2°C warming targets this century. This gap has motivated growing research into climate intervention \, broadly divided into two strategies with distinct risk profiles. Solar radiation modification (SRM\, via stratospheric aerosol injection (SAI) an d marine cloud brightening (MCB)\, aims to cool the planet by increasing s unlight reflection\, but lacks a proven\, scalable delivery technology and carries unresolved risks of regional heterogeneity and termination shock\ , alongside contested governance as private and philanthropic actors enter the space. Marine carbon dioxide removal (mCDR) instead seeks to reduce a tmospheric CO2 by accelerating ocean carbon uptake via abiotic approaches (ocean alkalinity enhancement\, mineral dissolution\, electrochemical meth ods) and biotic approaches (macroalgae and microalgae cultivation\, biomas s sinking)\; it is more publicly palatable and already advancing toward co mmercialization\, though verification and ecological side effects remain o pen questions. Across both strategies\, ecosystem responses are poorly con strained\, from how marine systems respond to SRM's altered temperature\, radiation\, and circulation regimes\, to how mCDR reshapes ocean biogeoche mistry. This talk provides an overview of the current state of SRM and mCD R\, emphasizing key knowledge gaps and the research efforts needed to clos e them.
