El Nino caused record Carbon dioxide spike in 2015-16

With its impressive collection of observational capabilities, OCO-2 will enable measurements of atmospheric Carbon dioxide to be made with sufficient precision, resolution, and coverage to faithfully characterize its sources and sinks globally over the seasonal cycle, a long-standing goal in atmospheric and climate science.

The findings reflect 28 months of data from NASA's Orbiting Carbon Observatory-2. A set of five papers in Science analyzes OCO-2 data collected from 2014 to 2016, identifying seasonal effects on the carbon cycle as well as the influence of the 2015-16 El Niño weather event.

The highest rates of atmospheric Carbon dioxide in 2,000 years stemmed from one of the most intense El Nino events on record, according to research published in the October 12 issue of Science.

The spikes recorded by OCO-2 indicated that the carbon dioxide emissions got a 50 percent increase in the year 2015-16 as compared to the average carbon emissions of preceding years.

In Africa, hotter-than-normal temperatures led to faster decomposition of dead trees and plants, releasing more carbon into the atmosphere.

United Nations sanctions against North Korea were last month expanded to include North Korean guest workers, along with textiles and a cap on oil exports.

The OCO-2 satellite, launched in 2014, is created to provide a detailed picture of how carbon is exchanged between air, land and sea. The super-sized El Nino a couple of years ago led to an increase of 3 billion tons of carbon in the air, most of the tropical land areas.

It should be noted that emissions of carbon dioxide due to anthropogenic factors has remained at the same level.

Together, these regions released 2.5 gigatons more carbon into the atmosphere than they did in 2011, the reference year for the study.

Out of 5 studies, two studies were about 2015-2016 El Niño's impact on the carbon cycle, and one study was done to track carbon emission from Volcanoes and cities, according to Motherboard (magazine). And some computer simulations say the frequency of El Nino will increase in the future with climate change, Denning said during a NASA press conference.
