Vice News: Scientists hope this volcano can save us from a fiery death

"“If the solar radiation management is halted for any reason, then a rapid warming would result, with likely catastrophic consequences,” Dennis Hartmann, a professor of atmospheric sciences at the University of Washington told tech and science website Futurism."

Tech Times: Can Volcanoes Help Cool The Earth? Scientists Are Preparing For The Next Big Eruption

"What is geoengineering? Simply put, geoengineering is an attempt to reduce or mitigate the effects of climate change by directly altering certain parts of the Earth's natural systems. An example of this is the process of injecting the atmosphere with sulfate particles to mimic the cooling effects of a volcanic eruption."

New York Times: The Next Big Volcano Could Briefly Cool Earth. NASA Wants to Be Ready

"One geoengineering approach would use high-flying jets to spray similar chemicals in the stratosphere. So by studying the next big volcanic eruption, scientists would also gain insights into how such a scheme, known as solar radiation management, or S.R.M., might work. “This is important if we’re ever going to do geoengineering,” said Alan Robock, a Rutgers University researcher who models the effects of eruptions and who has been involved in discussions about the rapid-response project. “But even if there were no such thing as geoengineering, it’s still important to understand how volcanoes affect climate.”"

TeCake: The Volcano that can aid to reduce global warming, says NASA

"Alan Robock, a climatologist at Rutgers University, who studies volcanic eruptions and has been involved in discussions about the rapid-response project, says in a statement, “This is important if we’re ever going to do geoengineering.” He continues further, “but even if there were no such thing as geoengineering, it’s still important to understand how volcanoes affect climate.”"

Mongabay: Climate scientists see silver lining in Bali volcano’s ash cloud

"Scientists are monitoring the emission of sulfur dioxide from the ongoing eruption of Indonesia’s Mount Agung to better understand the climate-cooling effects of the particulate’s dispersal in the stratosphere. They hope that by artificially recreating the phenomenon, they can block the amount of sunlight reaching the Earth’s surface, and thereby “geoengineer” a cooler climate."

Reuters: Scientists look to Bali volcano for clues to curb climate change

"Climate scientists are tracking an erupting volcano on the Indonesian holiday island of Bali for clues about a possible short-cut to curb global warming by injecting sun-dimming chemicals high above the Earth. "

Vox: Bali’s fiery volcano could end up temporarily cooling the entire planet

"Scientists are also toying with the controversial idea of imitating volcanoes to keep global warming in check, a strategy known as geoengineering. This includes deliberately seeding clouds or spraying sulfuric acid into the stratosphere to offset some of humanity’s impacts on the world’s climate. "

Indipendent: Artificial volcanoes designed to reverse global warming could risk natural disasters, scientists warn

"Geoengineering to cool the Earth’s climate by imitating volcanic eruptions is a ‘highly risky strategy’ that may increase the frequency of cyclones and droughts in some parts of the world"

New24: Climate-disrupting volcanoes helped topple ancient Egypt: study

"The findings, the authors said, also highlight the risk today of climate engineering schemes that would combat global warming by injecting billions of tiny particles into the stratosphere - just like a volcano - to block some of the sun's rays. Even if so-called solar radiation management lowers the planet's temperature a notch or two, it could inadvertently cause major disruptions in rainfall patterns. "Ptolemaic vulnerability to volcanic eruptions offers a caution for all monsoon-dependent agriculture regions," which today include 70% of the world's population, the authors wrote."

van Hemer, Mieke (2016): Speculative promise as a driver in climate engineering research. The case of Paul Crutzen’s back-of-the-envelope calculation on solar dimming with sulfate aerosols

van Hemer, Mieke (2016): Speculative promise as a driver in climate engineering research. The case of Paul Crutzen’s back-of-the-envelope calculation on solar dimming with sulfate aerosols. In Futures. DOI 10.1016/j.futures.2016.11.006.

"In this paper, I study the generative role of speculative promise in climate engineering research. My analysis operationalizes Alfred Nordmann’s call for a ‘forensics of wishing’, a variety of technology assessment which scrutinizes the politics of anticipation in technoscience. Using scientific articles and reports as primary sources I trace the uptake and contestation of bold claims made by atmospheric scientist Paul Crutzen a decade ago."
