Scientists Push for a Crash Program to Scrub Carbon From the Air

With time running out to avoid dangerous global warming, the nation’s leading scientific body on Wednesday urged the federal government to begin a research program focused on developing technologies that can remove vast quantities of carbon dioxide out of the atmosphere in order to help slow climate change.
The 369-page report, written by a panel of the National Academies of Sciences, Engineering and Medicine, underscores an important shift. For decades, experts said that nations could prevent large temperature increases mainly by reducing reliance on fossil fuels and moving to cleaner sources like solar, wind and nuclear power.
But at this point, nations have delayed so long in cutting their carbon dioxide emissions that even a breakneck shift toward clean energy would most likely not be enough. According to a landmark scientific report issued by the United Nations this month, taking out a big chunk of the carbon dioxide already loaded into the atmosphere may be necessary to avoid significant further warming, even though researchers haven’t yet figured out how to do so economically, or at sufficient scale.
And we’ll have to do it fast. To meet the climate goals laid out under the Paris Agreement, humanity may have to start removing around 10 billion tons of carbon dioxide from the air each year by midcentury, in addition to reducing industrial emissions, said Stephen W. Pacala, a Princeton climate scientist who led the panel. That’s nearly as much carbon as all the world’s forests and soils currently absorb each year.

How Scientists Cracked the Climate Change Case

The latest report from the world’s climate scientists has made clear the size of the challenge if the world is to stay below the global warming limit hoped for in the Paris climate agreement. Unfortunately, with current trends we are likely to cross this threshold within the next two decades because we are already two-thirds of the way there.
But how do we know what is driving these climate trends? It comes down to the same kind of detective work that typifies a crime scene investigation, only here we are dealing with a case that encompasses the whole world. Let me give you my view, which does not necessarily represent the position of NASA or the federal government.
For the past 100 years we have documented good, independently confirmed observations of change at the surface of the planet, and for the past 40 years satellites and comprehensive measuring efforts have provided a much fuller view of changes throughout the earth system. These observations show clearly that among other things, the surface of the planet has warmed, the upper atmosphere has cooled, the oceans are gaining an enormous amount of heat, sea level is rising, Arctic ice has greatly receded and glaciers around the world are in retreat.
