New climate warning as emissions hit high
Report says CO set to break record, 2 casting doubt on ability to reach goals
Global emissions of carbon dioxide have reached the highest levels on record, scientists projected yesterday, in the latest evidence of the chasm between international goals for combating climate change and what countries are actually doing.
Between 2014 and 2016, emissions remained largely flat, leading to hopes that the world was beginning to turn a corner. Those hopes have been dashed. Last year, global emissions grew 1.6 per cent. The rise this year is projected to be 2.7 per cent.
The expected increase, which would bring fossil fuel and industrial emissions to a record high of 37.1 billion tonnes of carbon dioxide per year, is being driven by nearly 5 per cent emissions growth in China and more than 6 per cent in India, researchers estimated, along with growth in many other nations throughout the world. Emissions by the United States grew 2.5 per cent, while emissions by the European Union declined by just under 1 per cent.
As nations are gathered for climate talks in Poland, the message of yesterday’s report was unambiguous: When it comes to promises to begin cutting the greenhouse gas emissions that fuel climate change, the world remains well off target.
“We are in trouble. We are in deep trouble with climate change,” United Nations Secretary General Antonio Guterres said this week at the opening of the 24th annual UN climate conference, where countries are wrestling with the ambitious goals they need to meet to sharply reduce carbon emissions in coming years.
“It is hard to overstate the urgency of our situation,” he added. “Even as we witness devastating climate impacts causing havoc across the world, we are still not doing enough, nor moving fast enough, to prevent irreversible and catastrophic climate disruption.” Guterres was not commenting specifically on yesterday’s findings, which were released in a trio of scientific papers by researchers with the Global Carbon Project. But his words came amid a litany of grim news in which scientists have warned that the effects of climate change are no longer distant and hypothetical, and that the impacts of global warming will only intensify in the absence of aggressive international action.
In October, a top UN-backed scientific panel found that nations have barely a decade to take “unprecedented” actions and cut their emissions in half by 2030 to prevent the worst consequences of climate change. The panel’s report found “no documented historic precedent” for the rapid changes to the infrastructure of society that would be needed to hold warming to just 1.5C above preindustrial levels.
Then late last month, the Trump Administration released a nearly 1700-page report co-written by hundreds of scientists finding that climate change is already causing increasing damage to the United States. That was soon followed by another report detailing the growing gap between the commitments made at earlier UN conferences and what is needed to steer the planet off its calamitous path.
Coupled with yesterday’s findings, that drumbeat of daunting news has cast a considerable pall over the international climate talks in Poland, which began this week and are scheduled to run until December 14.
Negotiators there face the difficult task of coming to terms with the gap between the promises they made in Paris in 2015 and what’s needed to control dangerous levels of warming — a first step, it is hoped, toward more aggressive climate action beginning in 2020. Leaders at the conference also are trying to put in place a process for how countries measure and report their greenhouse gas emissions to the rest of the world in the years ahead.
But while most of the world remains firmly committed to the notion of tackling climate change, many countries are not on pace to meet their relatively modest Paris pledges. The Trump Administration has continued to roll back environmental regulations and insist that it will exit the Paris agreement in 2020. Brazil, which has struggled to rein in deforestation, in October elected a leader in Jair Bolsonaro who has pledged to roll back protections for the Amazon.
The biggest emissions story this year, though, appears to be China, the world’s single largest emitting country, which grew its output of planet-warming gases by nearly half a billion tonnes, researchers estimate. The United States is the globe’s second-largest emitter. China’s sudden, significant increase in carbon emissions could be linked to a wider slowdown in the economy, environmental analysts said.
“Under pressure of the current economic downturn, some local governments might have loosened supervision on air pollution and car-
bon emissions,” said Yang Fuqiang, an energy adviser to the Natural Resources Defence Council, a US environmental organisation.
China’s top planning agency said yesterday that three areas — Liaoning in the northeast Rust Belt and the big coal-producing regions of Ningxia and Xinjiang in the northwest — had failed to meet their targets to curb energy consumption growth and improve efficiency last year.
But Yang said that these areas were not representative of the whole country, and that China was generally on the right track. “There is still a long way ahead in terms of pollution control and emissions reduction, but we expect to see more ambitions in central Government’s plans and actions,” he said.
Such changes — in all largeemitting nations — have to happen fast. Scientists have said that annual carbon dioxide emissions need to plunge almost by half by the year 2030 if the world wants to hit the most stringent — and safest — climate change target. That would be either keeping the Earth’s warming below 1.5C — when it is already at 1C — or only briefly “overshooting” that temperature.
But emissions are far too high to limit warming to such an extent. And instead of falling dramatically, they’re still rising.
Yesterday’s research makes clear the intimidating math behind the fundamental shift that scientists say is required. While some nations continue to grow their emissions and some are shrinking them, overall there are still more additions than subtractions.
“We’re not seeing declines in wealthy countries that outpace the increases in other parts of the world,” said Rob Jackson, a researcher at Stanford University who contributed to the research as part of the Global Carbon Project.
The problem of cutting emissions is that it leads to difficult choices in the real world. A growing global economy inevitably stokes more energy demand. And different countries are growing their emissions — or failing to shrink them — for different reasons.
“India is providing electricity and energy to hundreds of millions of people who don’t have it yet,” said Jackson. “That’s very different than in China, where they are ramping up coal use again in part because their economic growth has been slowing. They’re greenlighting coal based projects that have been on hold.”
The continuing growth in global emissions is happening, researchers noted, even though renewable energy sources are growing. It’s just that they’re still far too small as energy sources.
“Solar and wind are doing great, they’re going quite well,” said Glen Peters, director of the Centre for International Climate Research in Oslo and another of the Global Carbon Project authors. “But in China and India, the solar and wind are just filling new demand. You could say if you didn’t have solar or wind, emissions could be higher. But solar and wind are nowhere near big enough yet to replace fossil fuels.” The figures the researchers provided are an estimate based on available energy and cement industry data through the first nine months of the year, and projections based on economic trends and the amount of carbon different countries are believed to be emitting to use energy. The estimated growth could change a bit, Jackson said — it’s possible the final number could be between an increase of 1.8 per cent and 3.7 per cent. But either way, there’s little doubt that 2018 hit a new record high for global emissions.
