Technological interventions needed to handle climate change
Technological interventions is new mantra advocated in a new report released by Washington, DC-based climate policy organization SilverLining.It highlights the importance and necessity for immediate research in technological interventions in climate as part of a portfolio to ensure safety for communities and stability for natural systems.
The report, Ensuring a Safe Climate: A National Imperative for Research in Climate Intervention and Earth System Prediction, highlights societys exposure to near-term risk from climate change, describes possibilities for reducing warming by increasing the reflection of sunlight from the atmosphere (i.e., solar radiation management or solar geoengineering), and discusses the nature of research and governance required to assess possibilities of technological interventions.
The United Nations Intergovernmental Panel on Climate Change (IPCC) has also highlighted the need for intense technological interventions to combat climate change.
This report put lot of emphasis on geoengineering as an alternative plan ,if rise in temperature stopped at a manageable level. In fact ,Geoengineering is being envisioned as the next stretegy to arrest global warming and climate change. says prof Parthasarthi of university of Delhi.
Approaches in Geoengineering
There are two main methods which are being widely discussed in the geoengineering strategy:
CDR (carbon-dioxide removal ) method advocate removal of Greenhouse gases from atmosphere as these are root causes of global warming.main strategy to remove these green house gases are carbon capture and storage adopting man-made and natural means.
Solar radiation management (SRM)
SRM (solar radiation management) , method does not indents to disturb greenhouse gases.It advocate nuetralise or minimise their global warming effect by reflecting sunlight away from the earth by adopting various technological and natural means.
View of Emergency Manager
The expert panel at Emergency Manager magazine think that geoengineering strategy is based on theoretical models which are mostly untested on ground.large scale geoengineering actions may create risk for many ecosystems,survival and adaptation of many organisms and plants.The complex interplay of climate systems on Earth may get derailed as it is very much decided by temperature and its variations.The dream of rescuing the earth may turn into a disaster unmanageable for humanity.
Emergency Manager magazine thinks that we must take strong decisions to mend our behaviour and actions if we want to live on this planet.Government and each member of human race have to mend their ways to live.Technological interventions can be adopted on basis of proper large size research.
We Homo Sapiens,the newest species on earth, have endangered our survival by our own actions.the survival of other species is already at risk by our actions.
US actions on sunlight reflection interventions
The U.S. National Academy of Sciences recently announced the committee for a new study to define research and governance for sunlight reflection interventions, and proposals for assessment were recently raised in the United Nations. SilverLinings report is designed to help policymakers and others review concepts and considerations in advance of more comprehensive assessments.
Focuses on United States of America
The report focuses on the United States(USA) where research in climate intervention has arisen as a topic in Congress, including in a February 28, 2019 hearing in which Congressman Jerry McNerney raised the issue as being an area for political cooperation stating, There are engineering solutions that need to be addressed, but we need to have the political will to put those solutions into effect. Please work with us to find solutions that are sufficient to the threat.
To that end, the reports scope also includes international developments as well as recommendations for global engagement. We need additional options to address the risks of severe climate change in the next 10 to 30 years, states SilverLinings Executive Director, Kelly Wanser. Its critical that we generate more information on climate and alternatives to ensure safety. It aims to empower all members of society with better information, and this report is a tool for enabling many different stakeholders to engage in the discussion.
Among the reports key findings are the following:
Warming climate poses grave risks to people and ecosystems within the next 10 to 30 years, faster than the transitions required for greenhouse gas reduction or removal may take effect.
Atmospheric sunlight reflection techniques might prevent the worst impacts of climate change, but there is limited scientific information, no technology, and no formal funding for research. These approaches have risks and limitations and are not a replacement for reducing greenhouse gases, which must be restored to pre-industrial levels as rapidly as possible.
Investments are needed to assess interventions, including substantial improvements to climate predictions and a decade of modeling, observations, and small-scale experiments for technological interventions.
With the highest concentration of climate observation and research capabilities in the world, the United States is uniquely capable of supporting research and innovation in climate intervention, but open international collaboration will promote the strongest scientific and policy outcomes.
Governance is a critical concern. Existing laws and institutions have some jurisdiction over research and activity in the atmosphere, but climate interventions introduce new considerations. We currently lack sufficient information to develop governance models.
