How many geoengineering-related papers will be published in the year 2020?

Climate change geoengineering, defined by the United Kingdom’s Royal Society as “the deliberate large-scale manipulation of the planetary environment to counteract anthropogenic climate change” (Shepherd et al. 2009). Geoengineering involves the removal of greenhouse gases from the atmosphere, or attempts at reflecting more energy away from the planet to counter warming (Markusson et al., 2013). It is often presented as a complement to climate change mitigation and adaptation.

The most publications listed on Google Scholar in a single year was 4.310, which were published in the 2018 calendar year.

How many geoengineering-related papers will be published in the year 2020?


This question resolves as the number of geoengineering related papers published in the calendar year 2020. The following search query shall be used, which includes patents but excludes citations:

"Climate engineering" OR "geoengineering" OR "Solar radiation management" OR "Stratospheric Particle Injection" OR "Stratospheric aerosol injection" OR "Marine cloud brightening" OR "Ocean sulfur cycle enhancement"

A search for calendar year X has the date-range "custom range" with "X - X", i.e. for 2018 the "custom range" is "2018 - 2018", which searches for all the articles published in the calendar year 2018.

The search queries for each year will be executed on any day in the first week of January, 2021, which is when this question will resolve. In case Google Scholar reports rough figures, i.e. "about N" publications, this question resolves as this 'rough' figure.


Metaculus help: Predicting

Predictions are the heart of Metaculus. Predicting is how you contribute to the wisdom of the crowd, and how you earn points and build up your personal Metaculus track record.

The basics of predicting are very simple: move the slider to best match the likelihood of the outcome, and click predict. You can predict as often as you want, and you're encouraged to change your mind when new information becomes available.

The displayed score is split into current points and total points. Current points show how much your prediction is worth now, whereas total points show the combined worth of all of your predictions over the lifetime of the question. The scoring details are available on the FAQ.

Note: this question resolved before its original close time. All of your predictions came after the resolution, so you did not gain (or lose) any points for it.

Note: this question resolved before its original close time. You earned points up until the question resolution, but not afterwards.

Community Stats

Metaculus help: Community Stats

Use the community stats to get a better sense of the community consensus (or lack thereof) for this question. Sometimes people have wildly different ideas about the likely outcomes, and sometimes people are in close agreement. There are even times when the community seems very certain of uncertainty, like when everyone agrees that event is only 50% likely to happen.

When you make a prediction, check the community stats to see where you land. If your prediction is an outlier, might there be something you're overlooking that others have seen? Or do you have special insight that others are lacking? Either way, it might be a good idea to join the discussion in the comments.
