"This is the global threat of our time, and for the sake of future generations, our generation must move toward a global compact to confront a changing climate before it is too late," President Barack Obama proclaimed back in June to a roaring crowd in Germany. "That is our job, that is our task, we have to get to work."

But progress toward that goal has not been made.

What would it take to make action on climate change happen? A new report written by the Intergovernmental Panel on Climate Change (IPCC) shows that climate change is not only real but that it is primarily—if not entirely—caused by humans.

The United Nations-assigned panel published the first part of its findings in a report today. The full report is to be released over the course of the next year.

These assessment reports come out every five years and summarize the latest findings of peer-reviewed climate science. Some of the findings of the report, known as AR-5, have already been leaked to the media.

The findings show that climate scientists are 95 percent confident that humans are responsible for at least "half of the observed increase in global average surface temperatures since the 1950s."

Additionally, the data shows that the last 30-year period is "very likely" the warmest in the last 800 years.

Coral Davenport, Energy and Environment Correspondent for the National Journal, and Raymond Schmitt, a Senior Scientist at the Woods Hole Oceanographic Institution, worked on a previous IPCC Assessment Report. They join The Takeaway to explain the latest findings.
