Seemingly every week a new major report comes out sounding the alarm about the escalating crisis of climate change. You may have missed two of these from just this past week that join a drumbeat that often causes me to lose sleep as I worry about the future that my 6- and 8-year-old sons will inherit. First, on Saturday the sensors at the Mauna Loa Observatory in Hawaii indicated that concentrations of the greenhouse gas has reached 415 parts per million (ppm), which means that for every 1 million molecules of gas in the atmosphere, 415 are made up of carbon dioxide. This means that even if we manage to move rapidly toward renewable energy and use other measures to help stanch the steady flow of carbon dioxide into the atmosphere, the next generation will likely be saddled with permanent negative consequences of our artificially elevated levels of CO2. Also last week, the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (I.P.B.E.S.), a research arm of the United Nations, told the world that we may be on our way to losing as many as a million plant and animal species. The 1,000-plus page report details the effects of climate change on marine and other wildlife and emphasizes like never before the devastating impact of biodiversity loss to humans.
