World on track for 3C of warming under current global climate pledges, warns UN

Current climate commitments are insufficient to reduce emissions by the amounts needed to avoid dangerous levels of global warming, says Unep report

The commitments made by governments on climate change will lead to dangerous levels of global warming because they are incommensurate with the growth of greenhouse gas emissions, according to a new report.

The United Nations Environment Programme (Unep) said that pledges put forward to cut emissions would see temperatures rise by 3C above pre-industrial levels, far above the the 2C of the Paris climate agreement, which comes into force on Friday.

At least a quarter must be cut from emissions by the end of the next decade, compared with current trends, the UN said.

The report found that emissions by 2030 were likely to reach about 54 to 56 gigatonnes of carbon dioxide equivalent a year, a long way astray of the 42 gigatonnes a year likely to be the level at which warming exceeds 2C.

Erik Solheim, chief of Unep, said the world was “moving in the right direction” on reducing greenhouse gas emissions and tackling climate change, but that measures should be taken urgently to avoid the need for much more drastic cuts in emissions in future. “If we don’t start taking additional action now, we will grieve over the avoidable human tragedy.”

He warned in particular that people would start being displaced from their homes by the effects of climate change, suffering from drought, hunger, disease and conflicts arising from these afflictions. Mass migration as a result of climate change is hard to separate from other causes of migration, but is predicted to become a much greater problem.

This year is “locked in” to be the hottest on record, according to Nasa, eclipsing last year’s record heat, and may show the way to future temperature rises and their accompanying problems.

Under the Paris agreement, reached last December, all of the world’s functioning governments have agreed to reduce greenhouse gases in line with the need to hold warming to no more than 2C, which scientists consider the limit of safety. That agreement has been ratified by the US, China and the European Union, and several other governments.

However, while all of the governments involved in the Paris accord have agreed their own domestic targets for curbing greenhouse gases, these are not legally binding. In addition, few countries have set out concrete plans for how they would implement the curbs.

Next week, signatories to the Paris agreement will gather in Marrakesh to flesh out some aspects of the pact reached last year. Supporters hope that some countries may come up with fuller plans for how they mean to achieve the necessary future emissions reductions, and countries that have not yet ratified the agreement will be persuaded to do so.

None are expected to announce new targets on emissions in line with the reductions that the Unep report suggests are necessary. Nations currently have domestic targets on curbing or cutting emissions by 2020, set out in 2009 at the UN meeting in Copenhagen, as well as their Paris commitments which apply from 2025 to 2030.

Asad Rehman, Friends of the Earth’s international climate campaigner, said: “This is a stark warning that cannot be ignored – tougher action on climate change is urgently needed to prevent the world speeding towards catastrophe. Governments are drinking in the ‘last chance saloon’ if the lofty goals of the Paris climate agreement are to be met.”

Richard Black, director of the Energy and Climate Intelligence Unit thinktank, said: “Unep’s report confirms that there has been remarkable acceleration towards a global low-carbon economy over the past year, but considerably more action is required if governments are to meet the target they set under the Paris agreement.”

Another significant climate agreement was signed in the last few weeks. Under the Montreal Protocol of 1987, countries agreed to phase out gases known to be harmful to the ozone layer. Some of the substitutes, however, turned out to be much more potent than carbon dioxide in warming the planet.

Under a new addition to that agreement countries around the world have agreed to remove the harmful HFCs used in some air-conditioning and refrigeration systems. If fully implemented, this could result in a 0.5C reduction in future warming. Given the goal set in Paris for limiting global temperature rises to 2C, this would make a significant difference to the world’s actions on climate change if it is fully endorsed. Phasing out the relevant chemicals may take much of the rest of the decade, however, and could face resistance in some industries.

Solheim urged countries to embark on more ambitious programmes to improve energy efficiency, increase the amount of energy coming from renewable sources, and look to meet the national targets they set in Paris.


UN paints apocalyptic picture of famine, war and disease unless world wakes up to dangers of climate change

'We will grieve over the avoidable human tragedy; the growing numbers of climate refugees hit by hunger, poverty, illness and conflict will be a constant reminder of our failure to deliver'

Ian Johnston Environment Correspondent, The Independent, November 3, 2016

The world will “grieve over the avoidable human tragedy” of climate change, as refugees flee “hunger, poverty, illness and conflict” unless urgent action is taken to reduce emissions from fossil fuels, the United Nations has warned.

Despite the Paris climate agreement being hailed as a the “moment we decided to save our planet” by US President Barack Obama among others, the UN Environment Programme (UNEP) said the commitments made by countries so far were “not nearly enough” to prevent disastrous global warming.

In a report, which UNEP said it hoped would be a “wake-up call to the world”, the world body estimated the Earth’s average temperature was set to increase by up to 3.4 degrees Celsius above pre-industrial levels by 2100 – the kind of change that would take at least tens of thousands of years to occur naturally, accomplished by humans in little over two centuries. It called for further measures to reduce greenhouse gases by a quarter by 2030.

Despite an overwhelming scientific consensus that climate change is real, the total amount of greenhouse gases produced by humans has continued to rise as countries have focused on short-term economic growth.

Next week world leaders will meet in Morocco for the first major climate summit after Paris, which organisers have pledged will be a “conference of concrete action”.

The UNEP report was unequivocal about the need for the countries to co-operate with that aim in mind.

“Everybody willing to look can see the impact of our changing climate. People already face rising seas, expanding desertification and coastal erosion. They take little comfort from agreements to adopt mitigation measures and finance adaptation in the future. They need action today,” wrote Erik Solheim, head of UNEP, and Jacqueline McGlade, UNEP’s chief scientist, in the report’s foreword.

But the reductions in greenhouse gases promised at Paris were “not nearly enough”.

“This report estimates we are actually on track for global warming of up to 3.4 degrees Celsius,” the foreword said. "Current commitments will reduce emissions by no more than a third of the levels required by 2030 to avert disaster. We must take urgent action. If we don’t, we will mourn the loss of biodiversity and natural resources. We will regret the economic fallout.

“Most of all, we will grieve over the avoidable human tragedy; the growing numbers of climate refugees hit by hunger, poverty, illness and conflict will be a constant reminder of our failure to deliver. None of this will be the result of bad weather. It will be the result of bad choices by governments, private sector and individual citizens.”

Under the Paris treaty, the world committed to trying to restrict global warming to as close to 1.5C as possible, a target that looks increasingly unlikely to be met given it is already at 1C.

A leading climate researcher, Professor Niklas Höhne, of the NewClimate Institute in Cologne, previously told The Independent that three degrees of warming would be “completely catastrophic”, resulting in a world that was “not very pleasant” for its human population with increasingly severe droughts, floods and storms.

It is also could trigger a number of ‘tipping points’ such as the melting of permafrost in the northern tundra, releasing vast amounts of methane, a potent greenhouse gas, that would send the temperature spiralling upwards.

Friends of the Earth’s international climate campaigner Asad Rehman said the UNEP report was “a stark warning that cannot be ignored”.

“Tougher action on climate change is urgently needed to prevent the world speeding towards catastrophe,” he said. “Governments are drinking in the last chance saloon if the lofty goals of the Paris Climate Agreement are to be met. Failure to act will not only result in more killer droughts, storms and misery – it will also hurtle us towards a future where food, water and a safe home will be a luxury for the few.

“Governments, including our own, must stop the suicidal dash for more climate-wrecking developments, such as fracking and airport expansion.”

Richard Black, director of the Energy and Climate Intelligence Unit (ECIU) in the UK, pointed to signs of hope in the UNEP’s report, such as the “remarkable acceleration towards a global low-carbon economy over the past year”.
