what is geoengineering?

ByEcosystems United

Geoengineering is deliberate, large-scale intervention in Earth’s natural systems to counteract climate change. The two most common forms are: SOLAR RADIATION MANAGEMENT (SRM) SRM techniques aim to reflect a small proportion of the Sun’s energy back into space, counteracting the temperature rise caused by increased levels of greenhouse gases in the atmosphere which absorb energy…

geoengineering explained: the benefits and challenges of ocean fertilization

ByEcosystems United

Ocean fertilization is an untested carbon dioxide sequestration (CDR) technique that involves dissolving nitrates or iron into the water which will encourage an increase in carbon uptake by phytoplankton. After the plankton blooms, it dies and then sinks to the ocean floor where the carbon will be stored as sedimentary rock. BENEFITS CHALLENGES Relatively safe…
