Explaining Extreme Events of 2013

A report released today investigates the causes of a wide variety of extreme weather and climate events from around the world in 2013. Published by the Bulletin of the American Meteorological Society, "Explaining Extreme Events of 2013 from a Climate Perspective (link is external)" addresses the causes of 16 individual extreme events that occurred on four continents in 2013. NOAA scientists served as three of the four lead editors on the report.

Of the five heat waves studied in the report, human-caused climate change was found to have clearly increased the severity and likelihood of those events. On the other hand, for other events examined like droughts, heavy rain events, and storms, fingerprinting the influence of human activity was more challenging. Human influence on these kinds of events—primarily through the burning of fossil fuels—was sometimes evident, but often less clear, suggesting natural factors played a far more dominant role.

"This annual report contributes to a growing field of science which helps communities, businesses and nations alike understand the impacts of natural and human-caused climate change," said Thomas R. Karl, L.H.D., director of NOAA’s National Climatic Data Center. "The science remains challenging, but the environmental intelligence it yields to decision makers is invaluable and the demand is ever-growing."

Confidence in the role of climate change about any one event is increased when multiple groups using independent methods come to similar conclusions. For example, in this report, five independent research teams looked at specific factors related to the record heat in Australia in 2013. Each consistently found that human-caused climate change increased the likelihood and severity of that event. However, for the California drought, which was investigated by three teams from the United States, human factors were found not to have influenced the lack of rainfall. One team found evidence that atmospheric pressure patterns increased due to human causes, but the influence on the California drought remains uncertain.

When human influence for an event cannot be conclusively identified with the scientific tools available today, this means that if there is a human contribution, it cannot be distinguished from natural climate variability.

"There is great scientific value in having multiple studies analyze the same extreme event to determine the underlying factors that may have influenced it," said Stephanie C. Herring, PhD, lead editor for the report at NOAA’s National Climatic Data Center. "Results from this report not only add to our body of knowledge about what drives extreme events, but what the odds are of these events happening again—and to what severity."

The report was edited by Herring, along with Martin P. Hoerling, NOAA’s Earth System Research Laboratory; Thomas Peterson, NOAA’s National Climatic Data Center, and Peter A. Stott, UK Met Office Hadley Centre and written by 92 scientists from 14 countries. View the full report online (link is external).

Putting Climate Polluters in the Dock

Can Caribbean governments take legal action against other countries that they believe are warming the planet with devastating consequences?

A former regional diplomat argues the answer is yes. Ronald Sanders, who is also a senior research fellow at London University, says such legal action would require all Small Island Developing States (SIDS) acting together.

He believes the Hague-based International Court of Justice (ICJ) would be amenable to hearing their arguments, although the court’s requirement that all parties to a dispute agree to its jurisdiction would be a major stumbling block.

“It is most unlikely that the countries that are warming the planet, which incidentally now include India and China, not just the United States, Canada and the European Union…[that] they would agree to jurisdiction,” Sanders told IPS.

“The alternative, if countries wanted to press the issue of compensation for the destruction caused by climate change, is that they would have to go to the United Nations General Assembly.”

Sanders said that the Caribbean Community (CARICOM) countries could “as a group put forward a resolution stating the case that they do believe, and there is evidence to support it, that climate change and global warming is having a material effect… on the integrity of their countries.

“We’re seeing coastal areas vanishing and we know that if sea level rise continues large parts of existing islands will disappear and some of them may even be submerged, so the evidence is there.”

Sanders pointed to the damaging effects of flooding and landslides in St. Vincent and the Grenadines, St. Lucia, and Dominica as 2013 came to an end.

The prime minister of St. Vincent and the Grenadines, Dr. Ralph Gonsalves, described the flooding and landslides as “unprecedented” and gave a preliminary estimate of damage in his country alone to be in excess of 60 million dollars.

“People who live in the Caribbean know from their own experience that climate change is real,” Sanders said.

“They know it from days and nights that are hotter than in the past, from more frequent and more intense hurricanes or freak years like the last one when there were none, from long periods of dry weather followed by unseasonal heavy rainfall and flooding, and from the recognisable erosion of coastal areas and reefs.”

At the U.N. climate talks in Warsaw last November, developing countries fought hard for the creation of a third pillar of a new climate treaty to be finalised in 2015. After two weeks and 36 straight hours of negotiations, they finally won the International Mechanism for Loss and Damage (IMLD), to go with the mitigation (emissions reduction) and adaptation pillars.

The details of that mechanism will be hammered out at climate talks in Bonn this June, and finally in Paris the following year. As chair of the Alliance of Small Island States (AOSIS), Nauru will be present at a meeting in New Delhi next week of the BASIC group (Brazil, South Africa, India and China) to try and build a common platform for the international talks.

“It isn’t just the Caribbean, of course,” Sanders said. “A number of other countries in the world – the Pacific countries – are facing an even more pressing danger than we are at the moment. There are countries in Africa that are facing this problem, and countries in Asia,” he told IPS.

“Now if they all join together, there is a moral case to be raised at the United Nations and maybe that is the place at which we would more effectively press it if we acted together. It would require great leadership, great courage and great unity,” he added.

Pointing to the OECD countries, Sir Ronald said they act together, consult with each other and come up with a programme which they then say is what the international standard must be and the developing countries must accept it.

“Why do the developing countries not understand that we could reverse that process? We can stand up together and say look, this is what we are demanding and the developed countries would then have to listen to what the developing countries are saying,” Sir Ronald said.

Following their recent 25th inter-sessional meeting in St. Vincent, Jamaican Prime Minister Portia Simpson Miller praised the increased focus that CARICOM leaders have placed on the issue of climate change, especially in light of the freak storm last year that devastated St. Lucia, Dominica and St. Vincent and the Grenadines.

At that meeting, heads of government agreed on the establishment of a task force on climate change and SIDS to provide guidance to Caribbean climate change negotiators, their ministers and political leaders in order to ensure the strategic positioning of the region in the negotiations.

In Antigua, where drought has persisted for months, water catchments are quickly drying up. The water manager at the state-owned Antigua Public utilities Authority (APUA), Ivan Rodrigues, blames climate change.

“We know that the climate is changing and what we need to do is to cater for it and deal with it,” he told IPS.

But he is not sold on the idea of international legal action against the large industrialised countries.

“I think what will cause [a reversal of their practices] is consumer activism,” he said. “The argument may not be strong enough for a court of law to actually penalise a government.”

But Sanders firmly believes an opinion from the International Court of Justice would make a huge difference.

“We could get an opinion. If the United Nations General Assembly were to accept a resolution that, say, we want an opinion from the International Court of Jurists on this matter, I think we could get an opinion that would be favourable to a case for the Caribbean and other countries that are affected by climate change,” he told IPS.

“If there was a case where countries, governments and large companies knew that if they continue these harmful practices, action would be taken against them, of course they would change their position because at the end of the day they want to be profitable and successful. They don’t want to be having to fight court cases and losing them and then having to pay compensation,” he added. More

Extreme weather is 'silver lining' for climate action: Christiana Figueres

Devastating extreme weather including recent flooding in England, Australia's hottest year on record and the US being hit by a polar vortex have a "silver lining" of boosting climate change to the highest level of politics and reminding politicians that climate change is not a partisan issue, according to the UN's climate chief. Christiana Figueres said that it was amoral for people to look at climate change from a politically partisan perspective, because of its impact on future generations.

The "very strange" weather experienced across the world over the last two years was a sign "we are [already] experiencing climate change," the executive secretary of the UN climate secretariat told the Guardian.

The flooding of thousands of homes in England because of the wettest winter on record has brought climate change to the forefront of political debate in the UK. The pprime minister, David Cameron, when challenged by Labour leader, Ed Miliband, on his views on man-made climate change and having climate change sceptics in his cabinet, said last week: "I believe man-made climate change is one of the most serious threats that this country and this world faces."

Climate change was barely mentioned at all in the 2012 US election battle until superstorm Sandy struck New York, prompting the city's then mayor, Michael Bloomberg, to endorse Barack Obama's candidacy because he would "lead on climate change."

Figueres said: "There's no doubt that these events, that I call experiential evidence of climate change, does raise the issue to the highest political levels. It's unfortunate that we have to have these weather events, but there is a silver lining if you wish, that they remind us is solving climate change, addressing climate change in a timely way, is not a partisan issue."

She added: "We are reminded that climate change events are for everyone, they're affecting everyone, they have much, much longer effects than a political cycle. Frankly, they're intergenerational, so morally we cannot afford to look at climate change from a partisan perspective."

Figueres said that examples of recent extreme weather around the world were a sign climate change was here now. "If you take them individually you can say maybe it's a fluke. The problem is it's not a fluke and you can't take them individually. What it's doing is giving us a pattern of abnormality that's becoming the norm. These very strange extreme weather events are going to continue in their frequency and their severity … It's not that climate change is going to be here in the future, we are experiencing climate change."

Figueres was speaking in London before meeting businesses including Unilever, Lafarge and Royal Dutch Shell to urge them to put pressure on governments to take action on climate change, ahead of renewed international negotiations in Bonn next week to flesh out details of a draft climate treaty to be laid out in Lima this year and agreed in Paris at the end of 2015.

"2014 is a crucial year because of the timing of next year, [in 2015] there will be very little time work on the actual agreement. We have to frontload the work," she said.

Peru's foreign minister told the Guardian in January that the Lima meeting in December must produce a first draft of a deal to cut carbon emissions, which will be the first of its kind after efforts to get legally binding agreement for cuts from most of the world's countries failed at a blockbuster meeting in Copenhagen in 2009.

Asked if a bad deal was better than no deal next year, she said: "Paris has to reach a meaningful agreement because, frankly, we are running out of time."

But she dismissed parallels with the run-up to the Copenhagen summit, saying the frequency of extreme weather events, lower renewable energy costs and progress on climate legislation at a national level meant it was different this time round.

"I hope that we don't need too many more Sandys or Haiyans or fires in Australia or floods in the UK to wake us up. My sense is there is already much momentum.We have 66 governments that have climate legislation, we have a total of 500 laws around the world on climate, whereas before Copenhagen we only had 47."

But the grouping of the world's 47 "least developed" countries said this week that they would want far more money to adapt their economies to climate change than the $100bn a year that been so far proposed by rich countries.

"We will want more than the $100bn to agree to a new Paris protocol," said Quamrul Choudhury, a lead negotiator for the group which includes many African and Asian countries. "On top of that we will want a legal mechanism to compensate for 'loss and damage' [compensation for extreme climate change events]. There should definitely be some space in the [final] treaty for that," he said in London.

He called on rich countries to compromise. "The battle lines are drawn. Everyone wants to defend their country and nobody will give an inch, but everyone has to make some sacrifice or we won't have a deal. We need high-level political commitment to raise ambition."

Choudhury, who is also Bangladesh's climate envoy to the United Nations, met British climate negotiators ahead of the Bonn talks. "I am optimistic that the world can avoid another diplomatic disaster like Copenhagen in 2009. There have been major changes since then. In 2008-09 we knew it would be very expensive to reduce emissions. Now we know it does not cost very much. It's not expensive, not a Herculean task. Countries like the UK know they can reduce emissions by 65% without it costing very much at all.

"But even if we have an ambitious mitigation target [to cut emissions] adaptation must be the cornerstone of a new treaty. This is not a zero-sum game. If we treat it like that there will be no Paris protocol," he said.

Figueres later agreed that the $100m proposed in 2009 as compensation for poor countries would not be enough for them to build defences and adapt their economies. "It was a figure plucked from a hat … $100bn is not enough [to meet] the mitigation and not at all for the adaptation costs. The International Energy Agency has suggested it may cost $1 trillion over 25 years just for adaptation. $100bn is a freckle on the map of what needs to be invested."

A major UN climate science panel report to be published at the end of this month will spell out the impacts of climate change on humanity and the natural world.Leaked versions of the report say agricultural production will decline by up to 2% every decade for the rest of the 21st century. More
