Recommendation

CO­2 levels have reached a record high and could lead to disastrous climate change if left unchecked. Besides reducing emissions, it has now become necessary to remove the CO­2 already in the atmosphere. New Yorker writer Elizabeth Kolbert gives an informative and cautionary look at two technologies for CO­2 removal, some of the major parties involved, and the challenges facing the technologies’ widespread application. getAbstract recommends this article to those who are interested in cutting-edge, world-saving technologies and who enjoy moderate weather.

In this summary, you will learn

  • What technologies exist to remove CO­2 from the atmosphere,
  • Why CO­2 removal has become essential and
  • What challenges there are to large-scale use of these technologies.

Summary

The process of “negative emissions” subtracts CO2 from the atmosphere, and is a way to limit the rise of global temperatures.

“Negative emissions” refers to the technologies that can limit rising global temperatures by removing CO­2 from the atmosphere. The idea comes from German physicist Klaus Lackner, who founded and now runs the Center for Negative Carbon Emissions at Arizona State University.  

Direct air capture is a technology that removes COdirectly from the air.

Direct air capture technology takes CO­2 directly from the air and turns it into calcium carbonate. As this technology targets CO­2 in ambient ...
