No, what they're saying is nature is contributing a negative 10% and man is contributing 110%. We'd be cooling if it wasn't for evil mankind.
Im amazed I just decoded BOTs gibberish from your (less) wrong post. Anthropogenic greenhouse gases are responsible for ~110% of the observed warming, but the primary cooling influence has actually been human sulfate pollution.
From that article:
The black bar indicates the amount of global surface warming observed from 1951 to 2010. The green bar shows the amount of warming caused by human greenhouse gas emissions during that time. The yellow is the influence from other human effects (mainly cooling from human sulfate aerosol emissions, which scatter sunlight), and the orange is the combined human effect. Below those are the contributions from external natural factors (mainly the sun and volcanoes) and from natural internal variability (mainly ocean cycles), while the whiskers show the uncertainty range for each.

IPCC AR5 figure 10.5: Likely ranges (whiskers) and their mid-points (bars) for attributable warming trends over the 19512010 period due to greenhouse gases, other anthropogenic forcings (OA), natural forcings (NAT), combined anthropogenic forcings (ANT) and internal variability. The HadCRUT4 observations are shown in black.
Notice that the green and orange bars are both bigger than the black bar. This shows that greenhouse gases have caused more warming than has been observed over the past six decades, but some of that was offset by cooling from human aerosol pollution. And the best estimate from the body of peer-reviewed climate science research is that humans are responsible for more than 100% of the global surface warming since 1950, with natural factors probably offsetting a little bit of that with a slight cooling influence
The natural cooling youre alluding to is even less significant than other anthropogenic forcings. It turns out the scientific consensus is that natural forcings and internal variability (i.e. natural cycles) just arent as significant as human influences
