Gina McCarthy, administrator of the EPA, asked scientists at a climate change conference on Thursday in Arlington, Va., to help advance President Obama’s agenda on climate change. 'Scientists, you folks help us understand our world,' McCarthy said at the 14th National Conference and Global Forum on Science, Policy and the Environment: Building Climate Solutions, sponsored by the National Council for Science and the Environment (NCSE). 'You help EPA to meet our mission of public health protection and environmental protection. I need you now more than ever to speak the truth,' McCarthy said. 'I need you to stand up together with us and explain what the science is telling you. To tell people that science and technology improvements will allow us to take action moving forward that meets the needs of this president as he has charged EPA, which is to look at climate change as something where we can innovate and we can move forward to grow the economy, to grow jobs, to understand how we’re producing sustainable, livable communities,' McCarthy said.
