Experts are more certain than ever that human activity is changing the global climate, even though they don’t fully understand every detail of the climate system, according to a new report released Wednesday by two of the world’s leading scientific bodies.

The document from the U.S. National Academy of Sciences and the United Kingdom’s Royal Society aims to move the climate change debate beyond humans’ role in global warming to a discussion of how to limit the impacts on society.

“Climate change is happening. We see it in temperature, we see it in the melting ice, and we see it in sea-level rise,”Inez Fung, an atmospheric scientist at the University of California at Berkeley and a co-lead author of the report, told NBC News. The changes are due to rising atmospheric concentrations of carbon dioxide with a chemical signature from the burning of fossil fuels, she added.

The report, “Climate Change: Evidence and Causes,” is written in simple language and filled with pictures and graphs to illustrate why scientists are certain human activity is causing the climate to change.
