Record high Carbon dioxide emissions delay global peak


Record high Carbon dioxide emissions delay global peak

After steadying off for three years, a report published on Monday revealed that carbon dioxide emissions are expected to rise by the end of 2017 by about 2 percent.

"The slowdown in emissions growth from 2014 to 2016 was always a delicate balance, and the likely 2% increase in 2017 clearly demonstrates that we can't take the recent slowdown for granted", said Robbie Andrew, a senior researcher at Cicero in Oslo and co-author of the studies.

Carbon emissions in the USA declined 0.4 percent in 2017 according to the Global Carbon Project-less than in previous years. Those are smaller decreases than the average over the previous decade.

"By continuing to cause this inexorable rise in Carbon dioxide we are pushing the climate closer and closer to the edge of our comfort zone", said Professor Richard Betts, of the University of Exeter and the Met Office Hadley Centre. A report released earlier this year by scientists at Carbon Tracker, the Potsdam Institute for Climate Impact Research, and Yale University showed that global emissions must begin falling quickly after 2020 in order to keep the global temperature from rising more than 2 degrees Celsius above pre-industrial levels. "This is a window into the future", Le Quéré said.

The carbon budget report, referring to the International Monetary Fund (IMF) statistics, also flagged that all the nations collectively during the year would see GDP rise of 3.6% as compared to previous year.

It noted that this year's emission rise would follow three years of almost no growth in emissions.

It estimates that 37 billion tonnes of Carbon dioxide will be emitted from burning fossil fuels, the highest total so far. Similarly, the European Union emissions are expected to decline by 0.2% in 2017 when this group of 28 nations would collectively record 2.3% increase in their GDP.

The new analysis was based on the available energy use data for 2017 and projections for the latter part of the year.

Continuing the streak of sad news, atmospheric Carbon dioxide concentration reached 403 parts per million in 2016, and is expected to increase by 2.5 parts per million in 2017. "We do not know if the increase in emissions in 2017 is a one-off, or represents changes leading to more sustained upward pressure on emissions in the years ahead". They grew 1.9 per cent in the rest of world. "The use of coal, the main fuel source in China, may rise by 3% due to stronger growth in industrial production and lower hydro-power generation due to less rainfall". "This would essentially mean that we need to have policies to lock in the gains we have had in the last few years", Peters said.

"The federal government can slow the development of renewables and low-carbon technologies, but it can't stop it", Robert Jackson, a co-author of this year's Global Carbon Budget and a professor in Earth system science at Stanford University, said in a press statement.

"Policy makers in Bonn are preparing for the Global Stocktake under the Paris Agreement, that will start in 2018 and occur every five years, and this puts enormous pressure on the scientific community to develop methods and perform measurements that can truly verify changes in emissions within this five-yearly cycle", said Prof Le Quéré.
