Carbon monoxide levels at 405 ppm

The Guardian published an article claiming that renewables are taking over,carbon emissions are down and implies we are (sic) winning the war against global warming.

"The first is that the globe will probably rocket well past peak CO2 levels of 405 parts per million by April and May of this year. This jump has been pushed along by a baseline massive human CO2 emission and assisted by a record ocean warming event (El Nino) in the Equatorial Pacific. Overall, this new yearly record will be more than 55 parts per million higher than peak ‘safe’ levels of 350 parts per million recommended by some of the world’s top climate scientists."

There is no good news in any of this

Record annual increase of carbon dioxide observed at Mauna Loa for 2015

Mauna Loa Observatory is a premier atmospheric research facility that has been continuously monitoring and collecting data related to atmospheric change since the 1950's.

The annual growth rate of atmospheric carbon dioxide measured at NOAA’s Mauna Loa Observatory in Hawaii jumped by 3.05 parts per million during 2015, the largest year-to-year increase in 56 years of research.

In another first, 2015 was the fourth consecutive year that CO2 grew more than 2 ppm, said Pieter Tans, lead scientist of NOAA's Global Greenhouse Gas Reference Network.

Carbon dioxide levels are increasing faster than they have in hundreds of thousands of years,” Tans said. “It’s explosive compared to natural processes.”

Levels of the greenhouse gas were independently measured by NOAA’s Earth System Research Laboratory and by the Scripps Institution of Oceanography.
In February 2016, the average global atmospheric CO2 level stood at 402.59 ppm. Prior to 1800, atmospheric CO2 averaged about 280 ppm.

The last time the Earth experienced such a sustained CO2 increase was between 17,000 and 11,000 years ago, when CO2 levels increased by 80 ppm. Today’s rate of increase is 200 times faster, said Tans.  

The big jump in CO2 is partially due to the current El Niño weather pattern, as forests, plantlife and other terrestrial systems responded to changes in weather, precipitation and drought. The largest previous increase occurred in 1998, also a strong El Niño year. Continued high emissions from fossil fuel consumption are driving the underlying growth rate over the past several years.
