However al he national level the United Stales has IUX yet developed a comprehensive climate change policy. In the absence of a comprehensive policy direction technological advances arc creating alternatives to the traditional approaches to climate change mitigation and adaptation it deployed these new technologies could modify the Earth s climate on a large scale Moreover. these new technologies may become available to foreign governments and entities in the private sector to use unilaterally without authorization from the United State government or an international treaty The term geoengincering describes this array of technologies that aim. through large-scale and deliberate modifications of the Earth s energy balance. to reduce temperatures and counteract anthropogenic climate change. Most of these technologies arc at the conceptual and research stages and their effectiveness at reducing global temperatures has yet to be proven Moreover very lew studies have been published that document the cost environmental effects. sociopolitical impact s and legal implications of gcocngincering. If geoengiiwuring technologies were IO be deployed they are expected to have the potential to cause significant transbuundary effects. In general geoengineering technologies are categorized as either a carbon dioxide renxwal iCDR methodor a solar radiation management tSRM method. CDR methods address the wanning .
