Fighting for Facts and Family: What Will We Tell Our Kids?

, Research Director, Center for Science and Democracy

They call my name. I walk to the stage and sit at the mic. I feel the eyes of the government decision-makers in front of me and the audience watching below. I start to speak. I’m interrupted by a baby crying. My baby. He’s four weeks old and strapped to my chest. I look down and frantically try to put a pacifier in his mouth. I lose my place in my notes. An awkward pause. The audience hears only my baby crying as I struggle find the words I scribbled down in a notebook earlier. I finally find them, press on to the end of my testimony, and step off the stage.

Half a Degree of Warming Could be the Difference Between Survival and Extinction for Many Species

, deputy director, Climate & Energy Program

As a conservationist who has been ringing the alarm bells on climate change threats to biodiversity for more than 25 years, I hardly know where to start in responding to the findings of the newest, and most alarming, Intergovernmental Panel on Climate Change (IPCC) Special Report on the impacts of a 1.5°Celsius global warming.  I’m not surprised that the IPPC delivers more bad news after reviewing more than 6,000 recent scientific reports, but I am surprised by just how bad the news is.

Hurricane Michael Threatens Gulf Coast Homes and Military Bases

, climate scientist

We’re watching as Hurricane Michael rapidly gains strength on its way toward the Florida Panhandle. Using the most recent storm surge prediction for Michael—released by NOAA at 11 am Eastern today—and property level data provided by Zillow, our preliminary analysis indicates that nearly 50,000 coastal properties are at risk of storm surge inundation, though many more could be affected by flash flooding and heavy rain throughout the southeast.

Pathways to 1.5C: Carbon Budget in the IPCC Special Report

, senior climate scientist

The historic Paris Climate Agreement generated a request of the Intergovernmental Panel on Climate Change (IPCC) to prepare a Special Report on 1.5 degrees Celsius increase above pre-industrial temperatures. Scientists and government representatives are in the final stretch assessing that every word of the summary for policymakers (SPM) accurately conveys evidence presented in the report.  Policymakers, business leaders, and energy system planners will be paying close attention to what the SPM says about the carbon budget remaining to stay below 1.5 degrees Celsius.
