New study on CO2 emissions: The cursed coal

a Little time? At the end of text there is a summary.

For a short while, it looked as if the world had succeeded in reversing the trend in climate. In the years between 2014 and 2016, the emissions of greenhouse gases had risen in the world barely seen yet - after he had climbed at the beginning of the Millennium, yet each year, more than three percent.

Then the warning shot: The global CO2 came out last year emissions had risen to about 1.6 percent.

Well, that was obviously just a slip-up.

The carbon dioxide emissions has increased this year, according to a study, significantly - and is expected to reach a new record value. Mainly because more Oil and Gas would be burned, be increased emissions in 2018, according to a projection by more than two percent, warns the research group the Global Carbon Project. Also, the United Nations environment program released last week estimated that global CO2 emissions setting a new record.

Currently, representatives negotiate from almost 200 countries at the world climate conference in the Polish Katowice, concerning the rules for the implementation of the Paris climate agreement , with the help of the global warming to well below two degrees in 1.5 degrees are to be limited, compared to the pre-industrial era around 1750. (An Overview of the main points of the conference, see here.)

"The increase in emissions in 2017 could be seen as outliers, but in 2018 the increase is even stronger and it is not clear that the world does not have, on the objectives of the Paris agreement of 2015 membership," says Glen Peters from the center for International climate and environmental research in Oslo, in short, Cicero. Environmentalists had hoped that economic growth and increase in emissions have been decoupled from the global perspective.

coal advance is booming more

The 76 experts from 15 countries participate in the Global Carbon Project, to say now, but in 2018, an increase in emissions of between 1.8 and 3.7 percent. more Precisely, the value can be due to existing uncertainties. This year's projection, will be published in three various articles in the journals "Nature", "Earth System Science Data" and "Environmental Research Letters".

It is not sufficient to promote the Expansion of renewable energies, the author of the Study, Corinne Le Quéré, Director of the Tyndall centre for climate change research at the UK's University of East Anglia. "The desire to dispense with fossil fuels, must be extended to the whole economy."

according to The researchers, the energy demand for cars and Trucks, air travel, and ship traffic is too fast for the switch to renewable energy for electricity generation could offset. In addition, is likely to be increased accordingly, the use of coal as an energy carrier in 2018.

"It is clear that a rapid turnaround is needed. Only with a significant intensification of efforts in emission reductions, we can keep the Option open to 1.5 degrees still open," said Sabine walk from the Mercator Research Institute on Global Commons and Climate Change, which participates in the steering Committee of the Global Carbon Project.

Voluntary Commitments are not enough, States could make re-sharpening

in The year 2020 to come into force of climate agreement in Paris provides that States are not obliged to reduce emissions, but voluntary Commitments . According to estimates of the research network Climate Action Tracker, this would result in its present Form to a Temperature increase of 3.2 degrees until the end of the century. A comparison with the beginning of industrialization. Since then, it has increased the temperature however, in the cut is to a grade , maybe to 1.2 degree.

Detailed analysis of the DPA special report of the intergovernmental panel on climate change: The world is falling apart at the seams - it's a question of how much,

can be re-sharpening their Commitments. The IPCC had recently declared in a special report, to Achieve a One-degree-goal, would have to fall in global emissions up to the year 2030 in comparison to the 2010 45% and latest 2050 should be brought to the carbon dioxide emissions total to zero , according to the scientists. That in a big way so-called negative emissions - that is, the active Removal of CO2 from the air need not be, for many discussions among experts - because the methods are industrially available at the time. (Read here where the problems lie in the Detail.)

But instead of down the CO2 levels to go anyway for the time being, back to the top. The main driver for the increase in emissions in 2018 is needed, according to the report, rising energy China and India . It was "likely" that coal dominate the Chinese energy system in the next decade, says Jan Ivar Kors Bakken of Cicero, even if the Expansion of the Coal will probably not be as strong as the beginning of the Millennium.

In India is a strong growth for the rising emissions. Although both countries in a massive renewable energy - but the energy is increasing, demand still stronger.

in the United States , CO2 emissions have increased this year, therefore, mainly due to the weather were conditions in the cold months, according to the researchers. In the coming years, the U.S. emissions are expected to fall, however, according to the forecasts, again. Then cheaper electricity from new Gas-, Wind -, and solar power plants old coal would push plants out of the network.

In the European Union , which is for ten percent of global CO2 emissions, decreased emissions, according to the projection between 2.6 and 1.3 per cent.

the countries with The largest greenhouse gas emissions according to the "Global Carbon Project" in this order China , the United States , India , Russia , Japan , Germany , Iran , Saudi Arabia , South Korea and Canada . It is expected that the 28 States of EU - you can negotiate at the climate summit always together - together, they lie in third place, behind China and the United States.

The concentration of CO2 in the atmosphere will increase the projection that in the year 2018, further to an average of 407 ppm (molecules of CO2 per Million air molecules). The world meteorological organization (WMO), they rose in 2017 already 403,3 ppm on 405,5 .

CO2 is the main greenhouse gas and is created primarily by the burning of coal, Oil and Gas, cement production and other industrial processes, as well as by the internal combustion engines of cars, airplanes and ships. The concentration of CO2 is now more than 45 per cent higher than in pre-industrial times.

greenhouse gases Combined: After the year 2017, the global CO2 has risen, according to a forecast by the Global Carbon Project emissions again this year. The Plus is projected to be somewhere between 1.8 and 3.7 percent. More precisely, the value can be due to existing uncertainties. Important drivers of the rise of China and India. There the generation of electricity from renewable sources is growing, but not as strong as the overall demand for energy.
