We are hovering around 400 ppm for carbon in the atmosphere which is 50 ppm beyond the safe threshold; 350 ppm. The planet, as a result of CO2 being pumped into the atmosphere, has warmed by 0.85°C (Celsius), or 1.5°F (Fahrenheit), since pre-industrial times. It is now the scientific consensus that the warming of our planet is a result of anthropogenic (human induced) climate change. The effects of global warming at the 0.85°C threshold is already noticeable. Regardless of how bad things have gotten already, they pale in comparison to the effects that have yet to come.
