Toolkit: Big Picture Science
This interactive chart displays findings from NASA to help explain why the Earth is warming. Is it the Earth's orbit? The Sun? Volcanoes? This chart demonstrates that only greenhouse gas emissions can account for the warming we're seeing today.
This video explains - in just a few minutes - why we know climate change is happening and why we know humans are causing it. It may be worth watching a few times to capture the details and provides a great starting point to understanding the big picture of climate change science.
Climate change is ongoing across the national park system; an overwhelming majority of parks are already at the extreme warm end of their historical conditions. Here you can see the basic climate inventories featuring historical temperature and precipitation data of 289 national park units.
This is an extensive document with both summary and technical sections that represent international perspectives. It presents information about what consensus exists amongst scientists and policy makers around the world. (Their synthesis reports are published every few years.)
The National Research Council of the National Academies of Science published this three-part climate guide. Part 1 lays out the evidence for climate change, Part 2 examines impacts, and Part 3 looks at ways we can take action to adapt and mitigate climate change.
This overview from the Royal Society and the U.S. National Academy of Sciences answers twenty commonly asked questions about climate change and provides an overview of basic climate science.
This short guide presents information that is deemed important for individuals and communities to know and understand about Earth’s climate, impacts of climate change, and approaches to adaptation or mitigation. Principles in the guide can serve as discussion starters or launching points for scientific inquiry.
This study looks at how much carbon is currently being stored in national park lands and projects a decline of carbon sequestration by 31% through 2050.

This article in Park Science reveals that 96% of the land administered by the NPS is located in areas of observed 20th century warming and provides an overview of the range of impacts being felt.
