Boy NASA is becoming the biggest contributor for proof against AGW lately.

Here is another example of nature completely blowing the human contribution to carbon dioxide out of the water.

A new NASA study provides space-based evidence that Earth’s tropical regions were the cause of the largest annual increases in atmospheric carbon dioxide concentration seen in at least 2,000 years.

Scientists suspected the 2015-16 El Nino -- one of the largest on record -- was responsible, but exactly how has been a subject of ongoing research. Analyzing the first 28 months of data from NASA’s Orbiting Carbon Observatory-2 (OCO-2) satellite, researchers conclude impacts of El Nino-related heat and drought occurring in tropical regions of South America, Africa and Indonesia were responsible for the record spike in global carbon dioxide. The findings are published in the journal Science Friday as part of a collection of five research papers based on OCO-2 data.

“These three tropical regions released 2.5 gigatons more carbon into the atmosphere than they did in 2011,” said Junjie Liu of NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, California, who is lead author of the study. “Our analysis shows this extra carbon dioxide explains the difference in atmospheric carbon dioxide growth rates between 2011 and the peak years of 2015-16. OCO-2 data allowed us to quantify how the net exchange of carbon between land and atmosphere in individual regions is affected during El Nino years.” A gigaton is a billion tons.

You should read more. This phenomenon can affect the rate at which the atmospheric concentration increases, but the net result is still an increase from each year to the next. You didn't read far enough into the article you linked.

The annual increase in atmospheric carbon dioxide levels and the magnitude of the seasonal cycle are determined by a delicate balance between Earth’s atmosphere, ocean and land. Each year, the ocean, plants and trees take up and release carbon dioxide. The amount of carbon released into the atmosphere as a result of human activities also changes each year. On average, Earth’s land and ocean remove about half the carbon dioxide released from human emissions, with the other half leading to increasing atmospheric concentrations. While natural processes are responsible for the exchange of carbon dioxide between the atmosphere, ocean and land, each year is different. In some years, natural processes remove as little as 20 percent of human emissions, while in other years they scrub as much as 80 percent.
And the CO2 being sequestered in the oceans is hurting the sea critters, killing corals and will bite us in the ass at some point.

If and when we get to the point where the atmospheric CO2 is dropping, all that CO2 we put into the ocean will be released to diminish the rate of improvement.

This isn't about absorption rates its about what is causing the most Co2 and that is definitely nature.

Trees and plants don't only absorb human produced Co2 you know.

You could cut out all human emissions and we would still be seeing spikes in Co2 levels.

That means that no matter what we attempt to do we are not going to slow down global warming unless you can find a way to stop nature.

Try reading it again. You might understand at some point.
