‘Make love, not CO2’: Emissions level off, still too high to save climate
Emissions of planet-warming carbon dioxide stayed level in 2015 at 36.3 billion tonnes (GtCO2) and were projected to rise “only slightly”, by 0.2 percent in 2016, according to the annual Global Carbon Budget report compiled by teams of scientists from around the world.world Updated: Nov 14, 2016 11:12 IST
Carbon emissions from burning fossil fuels have been nearly flat for three years in a row — a “great help” but not enough to stave off dangerous global warming, a report said Monday.
Emissions of planet-warming carbon dioxide stayed level in 2015 at 36.3 billion tonnes (GtCO2) and were projected to rise “only slightly”, by 0.2 percent in 2016, according to the annual Global Carbon Budget report compiled by teams of scientists from around the world.
“This third year of almost no growth in emissions is unprecedented at a time of strong economic growth,” said research leader Corinne Le Quere of the University of East Anglia.
Driven largely by reduced coal use in China, this was a “clear and unprecedented break” with the preceding decade’s fast emissions growth, at a rate of some 2.3 percent per year from 2004 to 2013, before dipping to 0.7 percent in 2014.
“This is a great help for tackling climate change but it is not enough,” said Le Quere.
For the world’s nations to make true on the global pact to limit average global warming to two degrees Celsius (3.6 degrees Fahrenheit) over pre-Industrial Revolution levels, emissions must do more than level off, the study found.
A decrease of 0.9 percent per year was needed to 2030.
The concentration of greenhouse gases in the atmosphere has continued to grow, the report warned, hitting a record level of 23 GtCO2 last year that looked set to reach 25 GtCO2 in 2016.
Quota running out
The analysis was published in the journal Earth System Science Data, to coincide with the UN climate conference in Morocco.
Climate envoys are gathered in Marrakesh to put plans in place to execute the so-called Paris Agreement concluded in the French capital a year ago.
It envisions a dramatic reduction in greenhouse gas-producing coal, oil and gas use for energy.
The new report said humanity has emitted 2,075 GtCO2 since 1870 -- adding 40 GtCO2 in 2016 alone.
“We have already used more than two thirds of the emissions quota to keep climate change well below two degrees,” it warned.
“The remaining quota would be used up in less than 30 years at the current emissions level.”
Under the so-called Paris Agreement’s predecessor the Kyoto Protocol, rich nations had to meet emissions reduction targets. Developing countries were excused as they needed coal and oil to fuel rapidly growing populations and economies.
China, despite not having any Kyoto targets, has been fast moving away from coal -- driven in large part by major air pollution concerns.
After growth of 5.3 percent per year from 2005-2014, China recorded a decline of 0.7 percent in 2015 and is set for a 0.5 percent drop in 2016.
This decline in the world’s most populous nation and biggest greenhouse gas polluter “largely accounts” for the global trend, the report said.
The world’s number two emitter, the United States, decreased emissions by 2.6 percent in 2015, with a fall of 1.7 percent projected for 2017.
The election of Donald Trump, who has threatened to “cancel” the Paris pact, has cast a long shadow over the Marrakesh talks, where many fear the US will abandon its targets to the detriment of the global goals.
‘Make love, not CO2’
Thousands of people marched on Marrakesh to demand “climate justice” from global envoys gathered for UN talks on staving off worst-case-scenario global warming.
“It is an international march for all the people who suffer the results of climate change, yet had no role in causing it,” said Mohamed Leghtas of a Moroccan climate coalition of environment, human rights and labour groups.
“Climate change is a triple injustice: committed by the north against the south, by current generations against future ones, and by a minority which enriches itself from fossil fuel energy against the poor who are left to pick up the pieces,” he told AFP.
Native Peruvians, Berber groups and African associations formed part of the procession which snaked through the city, brandishing placards reading: “Make love, not CO2,” and “1.5 C to stay alive.”
The latter refers to the goals of the climate rescue Paris Agreement concluded at the previous round of UN talks in the French capital in 2015, and set the goal of limiting global warming to two degrees Celsius, or 1.5 C if possible.
“We are here to demand respect and to urge the world to commit to cutting greenhouse gases,” blamed for warming the planet, added Antolin Huascar of Peru’s agricultural confederation.
The protest took place on the sidelines of the 22nd Conference of Parties of the UN’s climate convention, COP22 for short, which runs until November 18.
Diplomats must negotiate rules for putting the hard-fought Paris Agreement’s goals into action.
On Tuesday, they will be joined by dozens of African heads of state, French President Francois Hollande and UN chief Ban Ki-moon.
“People must fight for their rights and not count on governments are under pressure from multinational corporations,” Khadija Riadi, a Moroccan human rights defender told AFP at the march.
“There can be no climate justice without respect for human rights.”
