Indonesia's fires labelled a 'crime against humanity' as 500,000 suffer

Raging forest fires across Indonesia are thought to be responsible for up to half a million cases of respiratory infections, with the resultant haze covering parts of Malaysia and Singapore now being described as a “crime against humanity”.

Tens of thousands of hectares of forest have been alight for more than two months as a result of slash and burn – the fastest and quickest way to clear land for new plantations.

Indonesia is the world’s largest producer of palm oil and fires are frequently intentionally lit to clear the land with the resulting haze an annual headache.

But this year a prolonged dry season and the impact of El Niño have made the situation far worse, with one estimate that daily emissions from the fires have surpassed the average daily emissions of the entire US economy.

The fires have caused the air to turn a toxic sepia colour in the worst hit areas of Sumatra and Kalimantan, where levels of the Pollutant Standard Index (PSI) have pushed toward 2,000. Anything above 300 is considered hazardous.

Endangered wildlife such as orangutans have also been forced to flee the forests because of the fires.

Six Indonesian provinces have declared a state of emergency.

Across the region Indonesia’s haze crisis has been causing havoc – schools in neighbouring Singapore and Malaysia have been shut down, flights have been grounded, events cancelled and Indonesian products boycotted, as millions try to avoid the intense smoke.

In the worst affected parts, on Sumatra and Kalimantan, ten people have died from haze-related illnesses and more than 500,000 cases of acute respiratory tract infections have been reported since July 1. More

Why Greenland’s “Dark Snow” Should Worry You

Jason Box's research into Greenland's dark snow raises more concerns about climate change.

Jason Box knows ice. That’s why what’s happened this year concerns him so much. Box just returned from a trip to Greenland. Right now, the ice there is … black:

The ice in Greenland this year isn’t just a little dark—it’s record-setting dark. Box says he’s never seen anything like it. I spoke to Box by phone earlier this month, just days after he returned from his summer field research campaign.

"I was just stunned, really," Box told me.

The photos he took this summer in Greenland are frightening. But their implications are even more so. Just like black cars are hotter to the touch than white ones on sunny summer days, dark ice melts much more quickly.

As a member of the Geological Survey of Denmark and Greenland, Box travels to Greenland from his home in Copenhagen to track down the source of the soot that’s speeding up the glaciers’ disappearance. He aptly calls his crowdfunded scientific survey Dark Snow.

There are several potential explanations for what’s going on here. The most likely is that some combination of increasingly infrequent summer snowstorms, wind-blown dust, microbial activity, and forest fire soot led to this year’s exceptionally dark ice. A more ominous possibility is that what we’re seeing is the start of a cascading feedback loop tied to global warming. Box mentions this summer’s mysterious Siberian holes and offshore methane bubbles as evidence that the Arctic can quickly change in unpredictable ways.

This year, Greenland’s ice sheet was the darkest Box (or anyone else) has ever measured. Box gives the stunning stats: "In 2014 the ice sheet is precisely 5.6 percent darker, producing an additional absorption of energy equivalent with roughly twice the US annual electricity consumption."

Perhaps coincidentally, 2014 will also be the year with the highest number of forest fires ever measured in Arctic.

Box ran these numbers exclusively for Slate, and what he found shocked him. Since comprehensive satellite measurements began in 2000, never before have Arctic wildfires been as powerful as this year. In fact, over the last two or three years, Box calculated that Arctic fires have been burning at a rate that’s double that of just a decade ago. Box felt this finding was so important that he didn’t want to wait for peer review, and instead decided to publish first on Slate. He’s planning on submitting these and other recent findings to a formal scientific journal later this year.

Box’s findings are in line with recent research that shows the Arctic is in the midst of dramatic change.

A recent study has found that, as the Arctic warms, forests there are turning to flame at rates unprecedented in the last 10,000 years. This year, those fires produced volumes of smoke and soot that Box says drifted over to Greenland.

In total, more than 3.3 million hectares burned in Canada’s Northwest Territories alone this year—nearly 9 times the long term average—resulting in a charred area bigger than the states of Connecticut and Massachusetts combined. That figure includes the massive Birch Creek Complex, which could end up being the biggest wildfire in modern Canadian history. In July, it spread a smoke plume all the way to Portugal.

In an interview with Canada’s National Post earlier this year, NASA scientist Douglas Morton said, "It’s a major event in the life of the earth system to have a huge set of fires like what you are seeing in Western Canada."

Box says the real challenge is to rank what fraction of the soot he finds on the Greenland ice is from forest fires, and what is from other sources, like factories. Box says the decline of snow cover in other parts of the Arctic (like Canada) is also exposing more dirt to the air, which can then be more easily transported by the wind. Regardless of their ultimate darkening effect on Greenland, this year’s vast Arctic fires have become a major new source of greenhouse gas emissions from the thawing Arctic. Last year, NASA scientists found "amazing" levels of carbon dioxide and methane emanating from Alaskan permafrost.

Earlier this year, Box made headlines for a strongly worded statement along these lines:

That tweet landed Box in a bit of hot water with his department, which he said now has to approve his media appearances. Still, Box’s sentiment is inspiring millions. His "f’d" quote is serving as the centerpiece of a massive petition (with nearly 2 million signatures at last count) that the activist organization Avaaz will deliver to "national, local, and international leaders" at this month’s global warming rally in New York City on Sept. 21.

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
