99.9999 percent chance we're the cause of global warming, study says

There's a 99.9999 per cent chance that humans are the cause of global warming, a new study reported Monday.

 There's a 99.9999 per cent chance that humans are the cause of global warming.

This means we've reached the "gold standard" for certainty, a statistical measure typically used in particle physics. 

Humanity burns fossil fuels such as oil, coal and gas, which release carbon dioxide (CO2) into the Earth's atmosphere and oceans. CO2 is the greenhouse gas that's most responsible for warming.

Study lead author Benjamin Santer of the Lawrence Livermore National Laboratory told Reuters that “the narrative out there that scientists don’t know the cause of climate change is wrong."
