Nov. 23: Luis E. Fernandez gave testimony at Peru's Ministry ofEnergy and Mines on issues related to deforestation, illegal gold mining and mercury contamination in the Peruvian States of Madre de Dios, Piura and Puno.
Nov. 5: Ken Caldeira addressed this question in his testimony to the U.S. House of Representatives Committee on Science and Technology in a hearing titled: Geoengineering: Assessing the Implications of Large-Scale Climate Intervention. Can global warming be mitigated by a technological fix such as injecting light-blocking particles into the atmosphere or chemically “scrubbing” excess greenhouse gases from the atmosphere? Neither Solar Radiation Management (SRM) nor Carbon Dioxide Removal (CDR) would be a climate cure-all, however. “If you take the risk of climate damage seriously, you want to take action to diminish risk by reducing greenhouse gas emissions, but you would not want to limit yourself to only one risk-reduction approach.” He stressed the need for a research program to uncover the limitations and potential pitfalls of geoengineering.
