Geoengineering is the deliberate and large-scale manipulation of the weather and climate using a variety of technologies.
One popular form of
geoengineering being explored by scientists is known as Solar
Radiation Management (SRM), a process which involves spraying
aerosols from planes equipped with particulates designed to reflect
sunlight in an effort to combat "anthropogenic
The researchers came to this conclusion by studying previous volcanic eruptions in Mexico and the Philippines.
The 1991 eruption of Mount Pinatubo in the Philippines and El Chichon in Mexico in 1982 caused a decrease in wheat, soy, and rice production due to the volcanic ash blocking sun light.
The researchers concluded that,
The team calls for more studies on the effects of solar radiation management on other global systems, including human health.
The research team published their study, Estimating Global Agricultural Effects of Geoengineering using Volcanic Eruptions, in the journal Nature.
Unfortunately, the UC
Berkeley study is only the latest in a long line of research
pointing to the dangerous outcomes involved with the implementation
of geoengineering technology.
During his speech Pasztor discussed the potential dangers of geoengineering, including the upcoming experiment being conducted by Harvard University in Arizona.
Pasztor is referencing Harvard engineer (and consistent proponent of climate engineering) David Keith and his plan for a new project, SCoPEx (Stratospheric Controlled Perturbation Experiment), which will assess the risks and benefits of deploying geoengineering on a large public scale.
Keith and fellow
engineer, Frank Keutsch, will research the benefits and risks
by spraying particles such as sulfur dioxide, alumina, or calcium
carbonate from a high-altitude balloon over Arizona during 2018.
The Carnegie Council has
previously called for global governance structures
to regulate the use of
The researchers warn that efforts to inject aerosols into the atmosphere to combat climate change may end up causing more harm to wildlife, the environment, and humanity.
The study, "Potentially
dangerous consequences for biodiversity of solar geoengineering
implementation and termination," was published in the journal
According to a 2013 study published in the Journal of Geophysical Research: Atmospheres, if geoengineering programs were started and then suddenly halted, the planet could see an immediate rise in temperatures, particularly over land.
Another study published in February 2015 by an international committee of scientists stated that geoengineering techniques are not a viable alternative to reducing greenhouse gas emissions to combat the effects of climate change.
The committee report called for further research and understanding of various geoengineering techniques, including carbon dioxide removal schemes and solar-radiation management before implementation.
The scientists found that SRM techniques are likely to present,
In addition, in late October 2016, the United Nations' Convention on Biological Diversity released a report examining the problems of geoengineering and whether or not humanity will be forced to employ the practice in an attempt to halt climate change.
The report, Update On Climate Geoengineering in relation to the Convention on Biological Diversity: Potential Impacts and Regulatory Framework, found that geoengineering,
...but also cause unpredictable rain and temperature distribution on the local level.
In addition, back in January a leaked draft report from the U.N. panel of climate experts (Special Report on 1.5 Degrees - Second Order Draft - Document for Review - SR15 - Summary for Policymakers - Draft) called geoengineering "economically, socially and institutionally infeasible."
The U.N. once again
recognized that geoengineering could disrupt weather patterns.
