National Academies Presidents Affirm the Scientific Evidence of Climate Change
Recently, questions have been raised about climate science. The National Academies have addressed many of these questions in our independent, evidence-based reports. We are speaking out to support the cumulative scientific evidence for climate change and the scientists who continue to advance our understanding.
Scientists have known for some time, from multiple lines of evidence, that humans are changing Earth’s climate, primarily through greenhouse gas emissions. The evidence on the impacts of climate change is also clear and growing. The atmosphere and the Earth’s oceans are warming, the magnitude and frequency of certain extreme events are increasing, and sea level is rising along our coasts.
The National Academies are focused on further understanding climate change and how to limit its magnitude and adapt to its impacts, including on health. We also recognize the need to more clearly communicate what we know. To that end, in 2018, the National Academies launched an initiative to make it easier for decision makers and the public to use our extensive body of work to inform their decisions. In addition, we will be expanding our Based on Science communications effort to include clear, concise, and evidence-based answers to frequently asked questions about climate change.
A solid foundation of scientific evidence on climate change exists. It should be recognized, built upon, and most importantly, acted upon for the benefit of society.
