Detailed explanation-1: -Three proactive strategies could reduce the risks of climate change: 1) mitigation: reducing emissions; 2) adaptation: moderating climate impacts by increasing our capacity to cope with them; and 3) geoengineering: deliberately manipulating physical, chemical, or biological aspects of the Earth system2.
Detailed explanation-2: -Geoengineering approaches include Natural Climate Solutions (e.g., Ecosystem Restoration, Blue Carbon, etc.) Solar Radiation Management, Carbon Dioxide Removal and a diverse array of Climate Change mitigation and adaptation methodologies.
Detailed explanation-3: -There are several proposed solar geoengineering technologies. These include marine cloud brightening, cirrus cloud thinning, space-based techniques, and stratospheric aerosol scattering, amongst others. Marine cloud brightening would attempt to brighten marine clouds to reflect more sunlight back into space.
