In 2014, for the first time in 40 years, global CO2 emissions have stalled, but… Good news, bad news: New data from the International Energy Agency (IEA) is showing that last year, for the first time in four decades, global CO2 emissions have “stalled,” remaining at about 32 billion tonnes, the same number as in 2013. “This is both a very welcome surprise and a significant one,” said IEA Chief Economist Fatih Birol. “It provides much-needed momentum to negotiators preparing to forge a global climate deal in Paris in December: for the first time, greenhouse gas emissions are decoupling from economic growth.” But while that’s encouraging, it shouldn’t lead the world to lose focus in its fight againstglobal warming. The reason is simple: While the rate has stopped increasing, it doesn’t mean that the concentration of CO2 in the atmosphere will stop increasing. The best way to illustrate this is with the carbon bathtub analogy: So far, every year we’ve been opening the carbon faucet wider, so that the bathtub has been filling up faster. There’s a leak at the bottom, so some is going out the drain (natural carbon sinks in the oceans and in forests, etc), but we’ve been pouring carbon in the tub faster than it leaks for a while now. All that the IEA news about 2014 means is that last year, we didn’t open the faucet more, it just keeps filling the tub at the same rate as in 2013. Said like that, it doesn’t sound so great, uh? But it’s still a good sign. I’d much rather see the rate stabilize, and eventually start to go down than to keep going up as it has been for decades. Hopefully it’s an early sign that we are decarbonizing our civilization, andturning more to clean sources of energy. Prof Corinne Le Quere, of the Tyndall Centre for Climate Change Research at the University of East Anglia, said: “An important factor could be that China’s coal consumption fell in 2014, driven by their efforts to fight pollution, use energy more efficiently and deploy renewables. “Efforts to reduce emissions elsewhere will have played a role, but there are also more random factors such as the weather and the relative price of oil, coal and gas.” (source)

Zaustavljen rast ispuštanja stakleničkih plinova Ovo je prvi put nakon 40 godina da nije zabilježen porast ispuštanja stakleničkih plinova u atmosferu, a da u isto vrijeme na svijetu nije bilo velike ekonomske krize Količina CO2 ispuštenog u 2014. godini ostala je na razini 32 gigatone što je isto kao i godinu dana ranije. Unatoč tome Svjetska energetska agencija je upozoila da iako su rezultati ohrabrujući to ''nije razlog da postanemoo nemarni''. ''Ovo je dobrodošlo iznenađenje koje je ujedno i vrlo važno'', rekao je glavni ekonomist Agencije Fatih Birol. Analitičari ovu stagnaciju ispuštanja CO2 pripisuju promjeni vrste energije koju koristi Kina i zemlje Organizacije za ekonomsku suradnju i razvoj. Profesorica Corinne Le Quere iz Tyndall Centra za istraživanje klimatskih promjena rekla je: '' Važan faktor bi moglo biti kinesko smanjivanje potrošnje ugljena koje je rezultat njihove borbe protiv zagađenja''. Osim smanjenja potrošnje ugljena važnu ulogu su odigrali i drugi faktori poput vremenskih prilika, cijene nafte, ugljena i plina, piše BBC. U 40 godina praćenja emisije stakleničkih plinova ovo je tek treći put da je zabilježena stagnacija ili pad njihovog ispuštanja u atmosferu
