Solar geoengineering may be effective in alleviating impacts of global warming on crops
Solar geoengineering - putting aerosols into the atmosphere to reflect sunlight and reduce global warming - is not a fix-all for climate change but it could be one of several tools to manage climate risks. A growing body of research has explored the ability of solar geoengineering to reduce physical climate changes. But much less is known about how solar geoengineering could affect the ecosystem New study shines light on hazards of Earth's largest volcano
Scientists from the University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science analyzed ground movements measured by Interferometric Synthetic Aperture Radar (InSAR) satellite data and GPS stations to precisely model where magma intruded and how magma influx changed over time, as well as where faults under the flanks moved without generating significant earthquakes.

The land-observing satellite was supposed to work for five years. Now, more than 20 years later, Landsat 7 is still going strong.
In April 2021, the satellite marked its 22nd year of serving as a set of eyes on our home planet, documenting Earth’s splendors such as the expansion of cities and calamities like volcanic eruptions and historic wildfires.
