Scientists are warning that the proof for man-made climate change is now at a gold standard level. The announcement increases the call to limit greenhouse emissions to help prevent future rises in global temperatures.

“Humanity cannot afford to ignore such clear signals,” a team of U.S. scientists noted in their findings.

Scientists say the evidence that humans are responsible for contributing to global warming is overwhelming and is now at the level they term “five-sigma.” This means that there is about a one-in-a-million shot that people are not part of the problem. This standard is the same one scientists used to establish the existence of the Higgs boson particle in 2012.

The lead scientist in the study, Benjamin Santer, hopes that the conclusions will make people realize that the scientific community understands what is causing global warming at a high degree of certainty.

Santer, who conducted the research from California’s Lawrence Livermore National Laboratory, says that narrative about the uncertainty of global warming needs to change.

“The narrative out there that scientists don’t know the cause of climate change is wrong,” Santer explained.

Experts agree that we are witnessing an increase in droughts, flooding, heat waves and higher ocean levels because of fossil fuel emissions. Despite the evidence, some politicians in the United States have tried to argue that global warming is not real and that being a part of the Paris climate initiative is a bad idea.

Fortunately, more and more Americans are starting to believe that humans are the cause of climate change. In fact, a poll from last year found that 62 percent of residents in the U.S. believe climate change has a human element. This is a big jump from 2013, when only 47 percent of Americans believed it was true.

Some scientists involved in the study, which used data gathered by satellites over the past decade, argue that the level of certainty about human involvement in climate change should be increased to closer to 99 or 100 percent.
