"The key lesson from this report is that humanity must take immediate action to reduce greenhouse gas emissions. The faster and deeper the emissions cuts, the lower the risk to farms, forests and pastures that nourish the planet," says Steven D. Allison, University of California, Irvine professor of ecology & evolutionary biology and earth system science. "Scientists can help by creating new ecological forecasting tools that deliver critical information to farmers and land managers facing climate change. It's also crucial that scientists work together with other disciplines and cultures, like indigenous groups, to preserve vital lands as the climate changes."
