Back in February, the Subcommittee on Energy and Environment of the U.S. House of Representatives Committee on Energy and Commerce held a hearing emitted “The Climate Crisis: National Security, Economic, and Public Health Threats.” World Climate Report’s Pat Michaels testified that we should be careful when assessing future threats from climate change because our understanding of what climate change the future may bring is grossly uncertain. Dr. Michaels backed up his contention by a demonstration that climate models are having a tough time getting the present and recent past right—which casts a pall on their future forecasts.
Also testifying at that hearing was General Gordon Sullivan (Ret.), President and Chief Operating Officer, Association of the United States Army who discussed potential national security threats from global warming—primarily from “unrest” in other parts of the world as food and water supplies grow scarce in some regions.
