Over the past two hundred years, the ocean and atmosphere have been accumulating massive amounts of carbon dioxide as factories, automobiles, airplanes, and more churn out the powerful greenhouse gas.
Over the past two hundred years, the ocean and atmosphere have been accumulating massive amounts of carbon dioxide as factories, automobiles, airplanes, and more churn out the powerful greenhouse gas. Two articles published recently in Nature by University of Hawai‘i at Mānoa oceanographers provide a reality check on the limitations of carbon dioxide removal and a warning that marine heatwaves need clear definitions so communities can adapt.
Carbon Dioxide Removal is Not the Golden Ticket
In all the scenarios assessed by the Intergovernmental Panel on Climate Change, nations around the world must dramatically and rapidly reduce their dependence on fossil fuels in order to limit global warming to 1.5–2 °C above pre-industrial levels. Further, the paths to limit warming also require the removal of carbon dioxide from the atmosphere, using methods that are still in the early stages of development.
However, David Ho, oceanography professor at the UH Mānoa School of Ocean and Earth Science and Technology (SOEST), wrote in his recent Nature article, “We must stop talking about deploying [carbon dioxide removal] as a solution today, when emissions remain high — as if it somehow replaces radical, immediate emission cuts. We have to shift the narrative as a matter of urgency.”
