 The floods in Pakistan will be distinguished in history not just as  possibly the worst humanitarian crisis of the age, but as the first  great ''natural'' disaster attributable to rising greenhouse gases.  ''There's no doubt that clearly the climate change is … a major  contributing factor,'' declared Dr Ghassem Asrar, the director of the  World Climate Research Program and the World Meteorological  Organisation.

'If this is not God's wrath, what is?'' asks  40-year-old taxi driver Bakht Zada, from Madyan in Pakistan's  north-west. His life's work was lost in the floods. On the BBC World  News channel, a grim-faced correspondent in Islamabad stands under a  black umbrella against grey skies, and recounts a horror story.
             One month after it started pouring rain, a fifth of  Pakistan is under water. About 20 million people - close to the entire  Australian population - have been washed from their homes, their life's  labours with them. About half remain in desperate need - camped on  levees, lacking food, drinking water, shelter, medicine. Foreign  governments have been slow to rouse in response, finding urgency only  now, world citizens trailing meanly in their wake.
The loss of property is catastrophic. ''It is as if a neutron bomb  exploded overhead but, instead of killing the people and leaving their  houses intact, it piled trees upon the houses and swept away the  villages and crops and animals, leaving the people alive,'' said a  Punjab farmer and writer, Daniyal Mueenuddin, in The New York Times.
             There are 1600 dead, not so many in the statistics of  disasters. But with disease brewing in the filthy water, the toll will  grow - probably not spectacularly enough to garner headlines. In the  long-term, there are fears the fragile nation's entire economy may be  beyond salvage.
             In aid parlance, they call this a slow-onset disaster,  which makes it difficult to ''market'' to potential donors. Just another  in the series of unfortunate, unprecedented events conspiring to shape  this catastrophe, which climate modellers have been forewarning in the  abstract for years, and which meteorologists could see brewing in  reality for weeks. It was no surprise.
             Against this backdrop, it is instructive to absorb a  couple of figures from an analysis produced by Oxfam International last  year. In the past decade, each year about 250 million people around the  world have been hit by climate-related disasters.
             Within five years, by 2015, environmental degradation and  an increasingly volatile climate are expected to inflate casualties by  50 per cent. Each year an average of 375 million men, women and children  will have their lives or their livelihoods taken by a change in the  weather. Modelling to imagine the future is never an exact science - the  numbers are fluid but the trajectory is unequivocal.
             Now apply another layer of numbers. The total the world  spent on humanitarian aid was $14.2 billion in 2006. By 2015, three  times that figure will be required to come close to answering the  escalating need.
             Where do you find the money to answer such need? You  probably don't, admits Andrew Hewett, the executive director of Oxfam  Australia. ''We will not be able to cope - the system is under huge  stress and strain even now.''
             Pakistan is the nightmare, the harbinger of a raw, new  reality, compelling governments and agencies with humanitarian missions  to rethink how they operate in a needier, more temperamental world.
             In the international media and science communities there  is vigorous debate over the claim - by a growing chorus of climate  experts - that the floods in Pakistan will be distinguished in history  not just as possibly the worst humanitarian crisis of the age, but as  the first great ''natural'' disaster attributable to rising greenhouse  gases. ''There's no doubt that clearly the climate change is … a major  contributing factor,'' declared Dr Ghassem Asrar, the director of the  World Climate Research Program and the World Meteorological  Organisation.
             Scientists are usually more comfortable with trends and  prognostications than with cause and effect - most would never ascribe a  single weather event to climate change. Which makes the declarations of  Asrar and similar ones from other experts all the more remarkable.
             But in a sense this debate is a sideshow. What is clear,  the scientists say, is that the floods in Pakistan - and the fires in  Russia, the mudslides in China, the droughts in sub-Saharan Africa - are  enunciations of scenarios climate forecasters have long predicted. The  ''unprecedented sequence of extreme weather'' over the past month match  climate projections, the WMO says. This is what global warming looks  like, say climate experts at NASA.
             For years the apocryphal warnings have been laid out in  the scientific journals and in sober economic analyses. Global warming  would super-saturate monsoons, extend droughts, breathe fury into  wildfires and frenzy into hurricanes and cyclones.
A study published in Science (Magazine)in  2006 found the level of heavy rainfall in the monsoon over India had  more than doubled in the past 50 years, and the authors predicted  increased disaster potential from heavy flooding. The human consequences  of such events have also been explicitly spelt out. Drought, floods,  violent winds, crop failures and the like all loom as triggers for  massive human migration and ''extended conflict, social disruption, war,  essentially, over much of the world for many decades'', in the words of  Lord Nicholas Stern, the former World Bank chief economist who laid out  the social and economic costs of warming in his report for the British  government in 2006.
             Taxi driver Bakht Zada may never know whether to raise  his prayers to God or his fist to polluting human industry. But  overwhelmingly scientists, relief agencies and strategic experts tell us  to pay close heed to Pakistan's devastation - it is the shape of things  to come.
             Unlike a tsunami or an earthquake, extreme weather events  often send strong warnings of their approach days, weeks, even months  in advance. In 2008, the International Federation of Red Cross and Red  Crescent Societies looked at the forecasts for a brewing, ugly monsoon  over West Africa and launched its first pre-emptive appeal for a flood  yet to happen. When the waters came, as predicted, there was at least  some readiness for them.
             In the same year, with storms brewing through the  Caribbean, forewarned Red Cross volunteers in Haiti worked around the  clock evacuating people and setting up first aid and relief. As limited  as these efforts were, they reflected a shift in thinking about disaster  response, with the recognition that pre-emptive action would always be  more effective than waiting for the aftermath.
             Better disaster preparedness and prevention was crucial,  the IFRC said when it released the latest World Disasters Report last  year. It calculated that nearly 60 per cent of disaster funds in 2008  went into answering the effects of events linked to climate change -  floods, storms, heatwaves and droughts - many of which would have given  meteorological notice. ''We can do better if we seek out risks before  they happen … capitalise on existing know-how and resources to refocus  disaster response onto prevention,'' said Mohammed Omer Mukhier, the  head of disaster policy at the IFRC.
             This message was powerfully reiterated by Ghassem Asrar  this week when he said that researchers had modelled the atmospheric  currents that brought the rains to Pakistan and the heat into Russia  weeks before they arrived. Climate scientists must urgently look into  ways to better read and broadcast the atmospheric signals, he said.  Leading scientists gathered in Colorado last week to try to do just  that.
             ''Precise local information on the evolving climate and  how it fits into the longer-term picture remains insufficient in many of  the most vulnerable parts of the world,'' said the chief of Britain's  Met Office, Peter Stott. ''There is no time to waste if we are going to  equip societies to better cope with the severity of weather in a  changing climate.''
             As scientists work to fine-tune their forecasting,  governments and agencies must invest an equally urgent effort into both  speedier, better co-ordinated response systems, and into the shift to  preparedness, says Dr Peter McCawley, a development economist and  disaster specialist at the Australian National University. This requires  a ''paradigm shift'' - investing in building up local institutions and  talking to communities about risks. ''It means moving from international  and national response after the event to local action before it. It  also involves a shift in power, which is why it will be difficult to  persuade people to do it.''
             The second critical step, he says, is to streamline  response to recognise ''need for speed''. Cash is a powerful  first-response tool, but it still gets badly stuck in bureaucratic  systems. Six months after the Haiti disaster, only 10 per cent of money  pledged by the international community to help had been disbursed.
             ''What's needed is a range of levers,'' says Hewett, who  identifies four key threads to better answering the next emergencies. He  echoes McCawley on the need for more resources, increased investment in  local preparedness, and reforms to the international system -  ''tackling some hard issues about getting better co-ordination, better  leadership''. Hewett adds to these ''more risk reduction - all the  arguments about reducing greenhouse emissions and investing in climate  change adaptations''.
             But to achieve this range of responses, aid donors -  whether they are governments or citizens - have to also shift their  mindset, be persuaded to put their money into programs stockpiling  emergency supplies, drawing up disaster plans, educating communities and  setting up early warning systems.
             Strengthening communities to withstand wild weather will  have to be built into the humanitarian groundwork, alongside things like  building schools, clinics, water and power supplies. Part of the  tragedy of Pakistan is that most of this critical infrastructure will  have to be rebuilt from ground zero.
             The head of Caritas Australia, Jack de Groot, illustrates  with the story of a small community in north-west Pakistan. Caritas and  local partners had installed latrines for 70 per cent of households; 75  per cent had access to safe drinking water; 90 per cent could access  power through micro-hydro plants. Now it is all pretty much gone, along  with 947 homes and six schools.
             ''It is very grim,'' de Groot says. Once again, the  poorest and most vulnerable of communities lose not only their homes and  services, but potentially their basic human rights and protections.  It's disheartening, but ''what do you do? You recognise that these are  human beings, with needs and rights, and you respond.''
             The flooding in Pakistan is ''a global disaster, a global  challenge. Pakistan is facing a slow-motion tsunami'', the UN  Secretary-General, Ban Ki-moon, said yesterday at a meeting in New York.  The forum wrung pledges from nations of another $180.5 million, largely  leveraged out of fears that a failure to deliver relief would give  terrorists more power in the destabilised region.
             Four years ago Professor Alan Dupont, now the director of  the Centre for International Security Studies at Sydney University,  co-authored a paper for the Lowy Institute on climate change and  security, Heating Up the Planet. It sought to highlight the devastating security implications of changing climate.
             Whether the Pakistan floods can be blamed on rising  greenhouse gases, Dupont can't and won't guess. But is this the kind of  event he was writing about? ''Absolutely,'' he says. ''One of the  concerns now is that perhaps the impact of these events might be even  wider than we thought. The science over the past four years is much  stronger. It's pretty clear that large swathes of the planet are  vulnerable.''
             Climate change raises fundamental questions of human  security, survival, and the stability of nation states, Dupont argues.  It will contribute to destabilising, unregulated population movements  through Asia and the Pacific. ''Where climate change coincides with  other transnational challenges to security, such as terrorism or  pandemic diseases, or adds to pre-existing ethnic and social tensions,  then the impact will be magnified.'' Pakistan fits all the flashpoint  criteria.
