SPECIAL REPORT / With time running short to agree a post-2020 international deal to tackle climate change, a new report warns that inaction puts the world at risk of greater climate volatility.
Climate change stands as one of the most controversial global challenges, often pitting the European Union against the rest of the world in what measures should be taken and who should pay for them.
Weather volatility headlines are often held up as proof of climate change: melting glaciers, catastrophic weather events like the recent flooding in Central Europe, killer cyclones in the United States, and droughts that have raised doubts about food security. There is also mounting scientific evidence.
“The climate change debate is a good example where the mainstream consensus opinion is that things are happening that will be adverse unless corrective action is taken [and] from a scientific perspective that principle holds,” said Mark Ferguson, director-general of the Irish Science Foundation.
“The debate is what action we need to take,” he told EurActiv at the European Risk Summit in Dublin.
So far, there is no clear consensus on remedies and post-Cold War efforts like the 1997 Kyoto agreement to reduce greenhouse gas emission have been met with scepticism despite concerns about the risk of inaction.
The United States, for instance, never ratified Kyoto and Canada withdrew from the protocol in 2011, citing the economic costs of reducing annual carbon dioxide emissions below 1990 levels. Developing countries won concessions at climate talks in 2010 to have rich nations pay for the shift away from fossil fuels through the Green Climate Fund although it has struggled to raise cash.
Christiana Figueres, the UN’s top climate change official, recently told international negotiators in Bonn that they needed to speed up climate talks if they are to meet a 2015 deadline for a new agreement that would come into force in 2020.
Those talks suffered a setback on Tuesday (11 June) when Belarus, Russia and Ukraine blocked further work by one of three key technical committees involved in climate change talks that began in the former German capital a week earlier. The move could slow progress before the next round of climate talks in Warsaw in November.
This week, the Paris-based International Energy Agency (IEA) – a body known best for its forecasting and market reports – warned that governments need to adopt new energy policies if the world is to limit the world’s temperature rise to 2° Celsius, the threshold level that is seen as avoiding climate upheaval.
But the report – Redrawing the Energy-Climate Map – shows the world is on course to exceed that marker.
“Climate change has quite frankly slipped to the back burner of policy priorities," said Maria van der Hoeven, the agency’s executive director.
The report, the former Dutch economy minister said, “shows that the path we are currently on is more likely to result in a temperature increase of between 3.6°C and 5.3 °C but also finds that much more can be done to tackle energy-sector emissions without jeopardising economic growth, an important concern for many governments.”
Still, concern about the economic risks is seen as a roadblock to progress, underscored by Canada’s decision to renege on its earlier endorsement of Kyoto. The economic growth argument blocked significant progress at the 2009 Copenhagen climate talks, and last year, emerging and developing nations teamed up against EU efforts to seek binding sustainability targets at the 20th anniversary of the Earth Summit in Rio de Janeiro, Brazil.
The first post-Cold War Earth Summit produced landmark environmental agreements on biodiversity, climate change and desertification, opening the door to the Kyoto Protocol on climate change that is to by succeeded by the new framework agreement in 2015.
The Rio event produced no major binding deals and the 100 leaders attending signed off on a conference document – The Future We Want – that was negotiated in advance.
'Almost irrefutable' evidence
Ferguson, who is also the chief science advisor to the Irish government, said the scientific evidence was “almost irrefutable” that human activities are fuelling climate change, including the use of fossil fuels and intensive agriculture.
“A good principle in addressing situations – whether it’s looking at drugs, food, climate, natural disasters or what have you – is that the greater the consistency and the coherence of the evidence and the analysis, the lower the likely that the principle conclusions derived from it will be overturned,” he said in a speech at the European Risk Summit.
But he said it was up to politicians, not scientific advisors like himself, to make the hard decisions on what policies should be pursued.
Extreme weather events are rare, which means that statistics are not always available analyse them. But a 2012 extreme weather report by the Inter-governmental Panel on Climate Change (IPCC) found it probable that the incidence of heat waves and floods had increased in recent years, although there are strong regional variations.
A rise in extreme coastal high water related to increases in mean sea level was also rated at between 66%-90% probability.
The IPCC’s scientists also expressed confidence that droughts were becoming more intense and longer, particularly in southern Europe and West Africa, but in central North America and north-western Australia the reverse seemed to be happening.
