Geoengineering is the term used to describe large-scale engineering projects meant to manipulate the planetary environment (usually in order to address climate change). Two items related to this topic are covered in this week's SciShow.
The first story notes that scientists in Italy are preparing to examine the supervolcano in the Campi Flegrei Caldera (the area around Naples) by drilling down toward the magma underlying the region. The study seeks to better understand the movement of magma in this area. Sensors will be placed 3.5 kilometers (2.2 miles) below the surface to gather information. Plans for a deeper bore were cancelled after concerns about the possibility of triggering earthquakes or gas releases.
Also in the news is SPICE (Stratospheric Particle Injection for Climate Engineering) an experimental method to deploy aerosols in the upper atmosphere (to potentially create a 'global cooling effect' to offset global warming). The British team planning this experiment had to put it on hold due to potential conflicts of interest over patents with some of the technology in the program.
More details about all of this can be found in this episode of SciShow on YouTube.
