May days heat sets up record El Niño

AppId is over the quota

Last month was the third warmest May since NASA satellites began taking the temperature of the planet 35 years ago, and was also the warmest May that did not fall within an El Niño Pacific warming event – which could mean a record-breaking appearance this year by the fearsome “Child”.
Scientists in the US says the global average was 0.33°C warmer than the seasonal norms for the month. The warmest May ever was in 1998 during the “El Niño of the century”, when global average temperatures rose by 0.56°C, and the second warmest at 0.45°C was in 2010, another El Niño year.
So if indications are correct that an El Niño event is taking shape in the Pacific right now off the equatorial coast of South America, then it could become a record-setter - even if it isn’t a very spectacular event - just because it will get a warmer start, according to John Christy, professor of atmospheric science at the University of Alabama in Huntsville, US.
An El Niño (Spanish for The Child, because it was first observed by Peruvian fishermen around Christmas) is a shift in the temperature patterns of the Pacific, as a blister of equatorial ocean heat moves eastwards. It is a natural cyclic event that tends to reverse the prevailing Pacific weather patterns, often damagingly, and is not connected with climate change - although its effects could be made worse by climate change.
“The long-term baseline temperature is about three tenths of a degree warmer than it was when the big El Niño of 1997-1998 began, and that event set the one month record,” Christy said. “With the baseline so much warmer, this upcoming El Niño won’t have very far to go to break that 0.66°C record. That isn’t to say it will, but even an average-sized warming event will have a chance to get close to that level.”
Meanwhile, according to new research in Nature Climate Change, people in the northern hemisphere can also expect warmer temperatures in autumn and winter – in spite of last winter’s spectacular ice storms in the US north-east that shut down cities from the Atlantic to the Midwest, and where - to the joy of headline writers - the town of Hell in Michigan froze over.
The report’s author, James Screen, Natural Environment Research Council research fellow at the University of Exeter, UK, says that even though there will be extremes of cold, these will be less frequent and less severe. The Arctic is warming, and a study of autumn and winter temperature variations shows that variability in the temperate zone overall has in fact decreased.
“Autumn and winter days are becoming warmer on average, and less variable from day to day,” Dr Screen said. “Both factors reduce the chance of extremely cold days.
“Cold days tend to occur when the wind is blowing from the north, bringing Arctic air south into the mid-latitudes. Because the Arctic air is warming so rapidly, these cold days are now less cold than they were in the past.”

Farmers growing a landmark genetically modified food crop in Bangladesh – Bt brinjal, or aubergine – have found themselves at the centre of a power struggle between the government and activists trying to prevent the technology getting a hold in the region.
The growers say they have been subjected to intimidation and misinformation about the safety of their produce by anti-GM campaigners. But in an effort to get the crop out to farmers quickly, the Bangladeshi government agency behind the project appears not to have followed some stipulations of its license to release the crops.
The $600,000 (£357,920) pilot scheme – which is owned and run by a Bangladesh Agricultural Research Institute (Bari) with support from USAid and Cornell University – is a pivotal moment for GM technology in south Asia.
Bt brinjal is southeast Asia's first GM food crop and has been brought to market after India's environment ministry imposed a moratorium on the release of a similar crop in 2010 pending further scientific scrutiny. Last May, a court in the Philippines also restricted the release of the crop citing lack of 'scientific certainty' on health and ecological safety.
"Activists and many others are fighting over these farmers to try to get them to say what is most convenient to their viewpoint," said Mark Lynas, communications adviser to the Bt brinjal project.
"The powerful anti-GMO lobby knows that if Bangladeshi farmers successfully adopt this new crop, other GMO crops in the pipeline such as golden rice (also being developed in Bangladesh) will be advantaged and their cause of banning the technology permanently will be harmed," he wrote in a blog about the project.
The country's agriculture minister Matia Chowdhury has even suggested that anti-GM activists have received kick-backs from pesticide companies that stand to lose out if the crop is adopted more widely – although she provided no evidence for the claim.
The new crop – which so far has had mixed cultivation success in the pilot farms – is a domestic variety of aubergine or egg-plant (locally called brinjal) which has been genetically modified with a gene from the soil bacterium Bacillus thuringiensis
– hence Bt brinjal. Mansur Sarker is the only Bt brinjal grower in Gazipur who has had a high yield. But he has to face the ire of people who are against the GM crop. Photograph: Saad Hammadi
The gene makes a protein that is deadly to a voracious and highly costly pest, a fruit and shoot boring caterpillar, but is harmless to humans and other animals. One big advantage, say its backers, is that farmers will not have to spray their fields with pesticide every two to three days – at a cost of between £76 and £380 per year depending on the extent of infestation. Less spraying also means environmental and health benefits with less collateral damage to wild insects and less pesticide residue on the fruit sold at market.
In granting license for the crop to farmers, the Bangladesh ministry of environment stipulated that Bari must satisfy technical demands to ensure that test fields were suitable and to protect local varieties and wild plants from receiving pollen from the GM plants.
One stipulation was that prior to release of the crops, the institute must, "formulate field production planning, field biosafety management planning ... safety measures such as isolation distance management planning, border row management planning, techniques for protection of local and indigenous variety and wild plants." But Bari's director Rafiqul Islam Mondal said that the institute did not check the fields before planting the crops. "We did not visit the fields ourselves," he said.
Another stipulation from the ministry was that Bt brinjal sold in market should be labelled as GM. However, in Jamalpur region the produce was sold without such labelling.
Mondal said grocers do not label any of the vegetables. "We expressed our reservation to the ministry when this [gazette] was issued," he said.
The backlash against the crop from anti-GM activists has been vehement with unsubstantiated claims that it may itself be harmful to human health and could lead to cancellation of exports of conventional brinjal crops to the EU.
Of the seven farmers the Guardian visited, four had received visits at their farms from people who claimed what they were growing was dangerous to people's health and trying convince them to cease their involvement. One of those recounted a similar experience at a market where his produce was denounced as unsafe by people opposed to GM technology.
"It will pose a great danger to the farmers and consumers who will not know what they are producing and what they are eating," wrote Farida Akhter, a green activist and founder of Naya Krishi Andolan (New Agricultural Movement) in an op-ed in Dhaka Tribune shortly after the crop was approved for small-scale growing by the government. "Brinjal is a very common vegetable consumed by majority of the population. So the risks are very high for the people in Bangladesh and even to the consumers in neighbouring India and those in Europe and Middle East."

There is no evidence that the crop causes any health problems in people, but Akhter says longer-term problems can't be ruled out. She accuses the government of exploiting the farmers' lack of understanding about the technology and said the farmers have only grown the crops because the government gave them free saplings. "Farmers are not even aware of the concerns related to the GM crop," she said.
The 20 farms in four regions of the country have become the focus of intense interest. Farmers have received frequent visits and inquiries from green activists, researchers and journalists. "They come, take photographs of the field and leave but we don't know what they are doing with it," said Babul Khan, a Bt brinjal farmer in Jamalpur.
Bari has tried to prevent farmers from speaking about their crops. "I am scared to even talk to anyone about my field. I don't know what would put me into trouble," said Haidul Islam, 44, in Gazipur. Some of the farmers have found it difficult to sell their produce at market because of rumours that the fruit are dangerous to eat.
Controversy about the project reached a new peak last month when two local newspaper articles – in the New Age and Financial Express – claimed that the crops had been a failure.
A third article, in the Dhaka Tribune, claimed that Helena Paul – which it described as a "London-based importer of vegetables" – had written to the government in December to "warn that the European Union would stop vegetable imports if any such genetically-modified eggplant is detected in a consignment." Paul is in fact an anti-GM activist who had written to the government in her capacity as director of the campaign group GM freeze.
The Bt brinjal project team reacted angrily to the suggestion that the technology was not working. They visited one of the farmers quoted in the Financial Express article and claim that he said two men had tried to coerce him into saying his crop had failed.

The Guardian has visited or spoken to all but one of the 20 farmers growing the Bt brinjal crop and established that it has so far had mixed results. While it appears to have successfully repelled the fruit and shoot borer pest as expected, some of the fields have succumbed to other ailments including bacterial wilt and drought. Of the 19 farmers, nine said they had had problems with the crop, with a failure rate of four out of five farms in Gazipur, the region closest to Dhaka.
Visits to the two farms in Jamalpur, over 124 miles north of the Bangladeshi capital, show the contrast in results. The region is a patchwork of meadows and green fields where the locals are largely farmers growing a variety of crops that are mostly trucked to the capital for sale.
Ratan Miah's farm has yielded 17 maunds (traditional baskets) of the vegetable since the beginning of May – and he says the crops sold well at market. The other farm in the region, owned by Babul Khan, has yielded only three maunds and more than half of his crops have died.
Akhter says that Bari should have had closer oversight over which farms were selected to grow the crops, how they were doing it and whether they were suitable.
Mondal said the "selection of the fields were wrong." Most of the test fields had cultivated conventional brinjals previously and so they contained pathogens of bacterial wilt and fungus left over from those conventional crops, he said.
But Frank Shotkoski, manager of the Agricultural Biotechnology Support Project II programme at Cornell, said that the problems with bacterial wilt was largely unavoidable. "We and the farmers were well aware of the fact that the fields were being planted during the wet season when bacterial wilt is more prevalent … There is little that can be done to prevent or control the pathogen when conditions are conducive for infection."
What is the crop?
The crop is a local variety of brinjal (aubergine or eggplant) that has been genetically modified to include a gene from the soil bacterium Bacillus thuringiensis
. This gene produces the toxin cry1Ac that kills fruit and shoot boring pest when it ingests the plant. Because the plant carries it own 'pesticide' the caterpillar does not need to be controlled by repeated rounds of pesticide spraying. The toxin is harmless to humans and other animals.
Who owns the crops?
The Bt gene was developed by the Maharashtra Hybrid Seed Company, the Indian partner of the US seed giant Monsanto and later donated to the public sector partners in India, Bangladesh and Philippines. Bt brinjal was developed by the government-operated Bangladesh Agricultural Research Institute with technical assistance from Cornell University in the US and funding from USAid. Monsanto still owns the technology but has granted a royalty-free, not-for-profit license to BARI to test, produce and distribute the plants other than by sale. Farmers will be encouraged to save seeds and use them in future.
• This article was corrected on 9th June 2014. It originally stated that Monsanto had no ownership rights over the technology. That has now been corrected.
