A combination of global warming and the El Niño weather system is set to make 2007 the warmest year on record with far-reaching consequences for the planet, one of Britain's leading climate experts has warned.
As the new year was ushered in with stormy conditions across the UK, the forecast for the next 12 months is of extreme global weather patterns which could bring drought to Indonesia and leave California under a deluge.
The warning, from Professor Phil Jones, director of the Climatic Research Unit at the University of East Anglia, was one of four sobering predictions from senior scientists and forecasters that 2007 will be a crucial year for determining the response to global warming and its effect on humanity.
Professor Jones said the long-term trend of global warming - already blamed for bringing drought to the Horn of Africa and melting the Arctic ice shelf - is set to be exacerbated by the arrival of El Niño, the phenomenon caused by above-average sea temperatures in the Pacific.
Combined, they are set to bring extreme conditions across the globe and make 2007 warmer than 1998, the hottest year on record. It is likely temperatures will also exceed 2006, which was declared in December the hottest in Britain since 1659 and the sixth warmest in global records.
Professor Jones said: "El Niño makes the world warmer and we already have a warming trend that is increasing global temperatures by one to two tenths of a degrees celsius per decade. Together, they should make 2007 warmer than last year and it may even make the next 12 months the warmest year on record."
The warning of the escalating impact of global warming was echoed by Jim Hansen, the American scientist who, in 1988, was one of the first to warn of climate change.
In an interview with The Independent, Dr Hansen predicted that global warming would run out of control and change the planet for ever unless rapid action is taken to reverse the rise in carbon emissions.
Dr Hansen said: "We just cannot burn all the fossil fuels in the ground. If we do, we will end up with a different planet.
"I mean a planet with no ice in the Arctic, and a planet where warming is so large that it's going to have a large effect in terms of sea level rises and the extinction of species."
His call for action is shared by Sir David King, the Government's chief scientific adviser, who said that 2006 had shown that the "discussion is now over" on whether climate change is happening. Writing in today's Independent, Sir David says progress has been made in the past year but it is "essential" that a global agreement on emissions is struck quickly. He writes: "Ultimately, only heads of state, working together, can provide the new level of global leadership we need to steer the world on a path towards a sustainable and prosperous future. We need to remember: action is affordable - inaction is not."
The demands came as the World Meteorological Organisation (WMO), the United Nations agency that deals with climate prediction, issued a warning that El Niño is already established over the tropical Pacific basin. It is set to bring extreme weather across a swath of the planet from the Americas and south-east Asia to the Horn of Africa for at least the first four months of 2007.
El Niño, or "the Christ child" because it is usually noticed around Christmas, is a weather pattern occurring every two to seven years. The last severe El Niño, in 1997 and 1998, caused more than 2,000 deaths and a worldwide damage bill of more than £20bn.
The WMO said its latest readings showed that a "moderate" El Niño, with sea temperatures 1.5C above average, was taking place which, in the worst case scenario, could develop into an extreme weather pattern lasting up to 18 months, as in 1997-98. The UN agency noted that the weather pattern was already having "early and intense" effects, including drought in Australia and dramatically warm seas in the Indian Ocean, which could affect the monsoons. It warned the El Niño could also bring extreme rainfall to parts of east Africa which were last year hit by a cycle of drought and floods.
Its effect on the British climate is difficult to predict, according to experts. But it will probably add to the likelihood of record-breaking temperatures in the UK.
The return of El Niño
* Aside from the seasons, El Niño and its twin, La Niña, are the two largest single causes of variability in the world's climate from year to year.
Both are dictated by shifts in temperature of the water in the tropical Pacific basin between Australia and South America. Named from the Spanish words for "Christ child" and "the girl" because of their proximity to Christmas, they lead to dramatic shifts in the entire system of oceanic and atmospheric factors from air pressure to currents.
A significant rise in sea temperature leads to an El Niño event whereas a fall in temperature leads to La Niña.
The cause of the phenomenon is not fully understood but in an El Niño "event" the pool of warm surface water is forced eastwards by the loss of the westerly trade winds. The sea water evaporates, resulting in drenching rains over South America, particularly Peru and Ecuador, as well as western parts of the United States such as California.
Parts of the western Pacific, including Indonesia and Australia, suffer drought. The effects can last for anything from a few weeks to 18 months, causing extreme weather as far afield as India and east Africa.
The co-relation with global warming is as yet unclear. Archaeological evidence shows El Niños and La Niñas have been occurring for 15,000 years. But scientists are investigating whether climate change is leading to an increase in their intensity or duration.

One of the world's leading experts on climate change has warned that the Earth is being turned into a "different planet" because of the continuing increase in man-made emissions of greenhouse gases.
In an interview with The Independent, Jim Hansen, who was one of the first scientists to warn of climate change in scientific testimony to the US Congress in 1988, claimed that we have less than 10 years to begin to curb carbon dioxide emissions before global warming runs out of control and changes the landscape forever.
Last year, Dr Hansen, director of the Nasa Goddard Institute for Space Studies, part of Columbia University in New York, complained that Nasa public relations officials appointed by the Bush administration had tried to gag him by limiting his access to the media. But in talking to this newspaper he was outspoken, warning that there are already worrying signs that global warming is beginning to trigger dangerous "positive feedbacks" within the climate, which can accelerate the rate of climate change.
Dr Hansen said: "We just cannot burn all the fossil fuels in the ground. If we do, we will end up with a different planet. I mean a planet with no ice in the Arctic, and a planet where warming is so large that it's going to have a large effect in terms of sea level rises and the extinction of species."
Positive feedbacks in the high latitudes of the northern hemisphere are already starting. One is the loss of sea ice, which means less sunlight and heat is reflected back into space, making the Arctic even warmer. Another is the release of methane from the frozen tundra. Methane gas is 20 times more potent than carbon dioxide as a greenhouse gas, Dr Hansen said.
"The greatest concern is that positive feedbacks at high latitudes do in fact seem to be coming into play. We can't just let those feedbacks get out of control or we will have passed a tipping point," he said.
"If we go another 10 years, by 2015, at the current rate of growth of CO2 emissions, which is about 2 per cent per year, the emissions in 2015 will be 35 per cent larger than they were in 2000. But if we want to get on a scenario that keeps global temperature in the range that it's been in for the last million years, we would need to decrease the emissions by something of the order of 25 per cent by the middle of the century, and by something like 75 per cent by the end of the century."
The continuing rise in carbon dioxide emissions and average global temperatures is on schedule to cause the eventual collapse of the ice sheets on both Greenland and the west Antarctic, with a catastrophic rise in sea levels.
"If we follow business as usual, and we don't get off this course where year by year we're getting larger and larger emissions of CO2, then we'll have large sea-level rises this century and I think that will become more apparent over the next decade or two," Dr Hansen said.
"The last time it was 3C warmer, sea levels were 25 metres higher, plus or minus 10 metres. You'd not get that in one century, but you could get several metres in one century," he said.
"Half the people in the world live within 15 miles of a coastline. A large fraction of the major cities are on coastlines. And the problem is that once you get the process started and well on the way, it's impossible to prevent it. That's why we need to address the issue before it gets out of control."
Many species of animals and plants are not going to cope with rising temperatures, which are causing isotherms - lines of equal temperature - to travel polewards at the rate of 50km a decade, compared with the average rate of species migration of 6km per decade.
"Those species at high latitudes have no place to go to. Many of them will be in trouble. They will effectively be pushed off the planet," Dr Hansen said.
Dr Hansen, who last year received the WWF Duke of Edinburgh Conservation Medal, said that although he is now free to speak out, many other US government scientists feel gagged.

By the end of tomorrow the average Briton will have caused as much global warning as the typical Kenyan will over the whole of this year, according to a report.
The findings highlight the glaring imbalance between the rich countries that produce most of the pollution and the poor countries that suffer the consequences in the forms of drought, floods, starvation and disease.
The World Development Movement (WDM), a poverty campaign group, has drawn up a "climate calendar" showing the dates when the UK will have emitted as much CO2 gas as other countries will in a year.
Unsurprisingly, the poorest counties such as Chad, Afghanistan and the Democratic Republic of Congo produce virtually no carbon emissions. Even populous countries such as India will be overtaken in its emissions by the UK in a month's time. In fact, 164 countries in the world have a smaller carbon footprint than the UK, while just 20, mainly including the major oil producers as well as the US, have a larger one.
By the end of tomorrow the average Briton will have produced 0.26 tonnes of CO2 emissions.
"The poorest countries in the world, with 738 million people, make no contribution to climate change, but it is those same people who face the worst consequences," Benedict Southworth, WDM's director, said. " One hundred and sixty thousand people are already dying every year due to climate change- related diseases and billions will face drought, floods, starvation and disease."
WDM has calculated the figures by taking the annual CO2 emission for each country, dividing by the number of people and then working out a daily contribution.
Thus while an Afghan on average will produce an annual equivalent of 0.02 tonnes of CO2, a Briton will produce 9.62 tonnes and the most prolific polluter - someone from the United Arab Emirates - will emit about 56 tonnes.
WDM acknowledged that its figures were based on averages that masked differences between life in rural and urban areas, but said that the figures still exposed the "injustice" of global warming.
"It is the richest people in the world who have produced and who are still producing most of the greenhouse gases causing climate change," Mr Southworth said.
The report said 7,800 Kenyans, Tanzanians and Rwandans died every year from diseases that were related to climate change. It warned that a 2C rise in temperature could lead to as many as 60 million more people being exposed to malaria in Africa.
The potential for massive ecological and human suffering as a result of climate change was a key finding in the report by Sir Nicholas Stern, although it was overshadowed by the political debate over the need for higher taxes or the imposition of rationing.
The Stern report found that many "vulnerable" regions embracing millions of people in sub-Saharan Africa were at risk from harvest failures, droughts and malaria.
It warned that these phenomena would affect the poorest people most of all and fuel conflicts and raise the number of child deaths as populations moved to avoid the worst-hit areas.
WDM said that although the Government had used the Stern report to show Britain's commitment to fighting climate change, emissions had risen 5 per cent under Labour.
It called on the Government to include legally binding annual targets to cut emissions in its Climate Change Bill.
Carbon comparison
The average British citizen produces 26kg of CO2 in a day. This breaks down as follows:
* 7.4 electricity
* 1.6 fuel production
* 3.8 manufacturing and construction
* 7.4 transport, of which: (5.2 road transport, 1.7 air travel, 0.1 railways and 0.4 shipping)
* 1.0 office buildings
* 3.8 residential heating
* 1.0 Other industrial processes, agriculture, military travel, other
The average Kenyan citizen produces 0.7kg of CO2 in a day. This breaks down as follows:
* 0.08 electricity
* 0.08 fuel production
* 0.16 manufacturing and construction
* 0.31 transport
* 0.07 other
How richest fuel global warming - but poorest suffer most from it

Europe, the richest and most fertile continent and the model for the modern world, will be devastated by climate change, the European Union predicts.
The ecosystems that have underpinned all European societies from Ancient Greece and Rome to present-day Britain and France, and which helped European civilisation gain global pre-eminence, will be disabled by remorselessly rising temperatures, EU scientists forecast in a remarkable report which is as ominous as it is detailed.
Much of the continent's age-old fertility, which gave the world the vine and the olive and now produces mountains of grain and dairy products, will not survive the climate change forecast for the coming century, the scientists say, and its wildlife will be devastated.
Europe's modern lifestyles, from summer package tours to winter skiing trips, will go the same way, they say, as the Mediterranean becomes too hot for holidays and snow and ice disappear from mountain ranges such as the Alps - with enormous economic consequences. The social consequences will also be felt as heat-related deaths rise and extreme weather events, such as storms and floods, become more violent.
The report, stark and uncompromising, marks a step change in Europe's own role in pushing for international action to combat climate change, as it will be used in a bid to commit the EU to ambitious new targets for cutting emissions of greenhouse gases.
The European Commission wants to hold back the rise in global temperatures to 2C above the pre-industrial level (at present, the level is 0.6C). To do that, it wants member states to commit to cutting back emissions of carbon dioxide, the principal greenhouse gas, to 30 per cent below 1990 levels by 2020, as long as other developed countries agree to do the same.
Failing that, the EU would observe a unilateral target of a 20 per cent cut.
The Commission president, José Manuel Barroso, gave US President George Bush a preview of the new policy during a visit to the White House this week.
The force of today's report lies in its setting out of the scale of the continent-wide threat to Europe's "ecosystem services".
That is a relatively new but powerful concept, which recognises essential elements of civilised life - such as food, water, wood and fuel - which may generally be taken for granted, are all ultimately dependent on the proper functioning of ecosystems in the natural world. Historians have recognised that Europe was particularly lucky in this respect from the start, compared to Africa or pre-Columbian America - and this was a major reason for Europe's rise to global pre-eminence.
"Climate change will alter the supply of European ecosystem services over the next century," the report says. "While it will result in enhancement of some ecosystem services, a large portion will be adversely impacted because of drought, reduced soil fertility, fire, and other climate change-driven factors.
"Europe can expect a decline in arable land, a decline in Mediterranean forest areas, a decline in the terrestrial carbon sink and soil fertility, and an increase in the number of basins with water scarcity. It will increase the loss of biodiversity."
The report predicts there will be some European "winners" from climate change, at least initially. In the north of the continent, agricultural yields will increase with a lengthened growing season and a longer frost-free period. Tourism may become more popular on the beaches of the North Sea and the Baltic as the Mediterranean becomes too hot, and deaths and diseases related to winter cold will fall.
But the negative effects will far outweigh the advantages. Take tourism. The report says "the zone with excellent weather conditions, currently located around the Mediterranean (in particular for beach tourism) will shift towards the north". And it spells out the consequences.
"The annual migration of northern Europeans to the countries of the Mediterranean in search of the traditional summer 'sun, sand and sea' holiday is the single largest flow of tourists across the globe, accounting for one-sixth of all tourist trips in 2000. This large group of tourists, totalling about 100 million per annum, spends an estimated €100bn (£67bn) per year. Any climate-induced change in these flows of tourists and money would have very large implications for the destinations involved."
While they are losing their tourists, the countries of the Med may also be losing their agriculture. Crop yields may drop sharply as drought conditions, exacerbated by more frequent forest fires, make farming ever more difficult. And that is not the only threat to Europe's food supplies. Some stocks of coldwater fish in areas such as the North Sea will move northwards as the water warms.
There are many more direct threats, the report says. The cost of taking action to cope with sea-level rise will run into billions of euros. Furthermore, "for the coming decades, it is predicted the magnitude and frequency of extreme weather events will increase, and floods will likely be more frequent and severe in many areas across Europe."
The number of people affected by severe flooding in the Upper Danube area is projected to increase by 242,000 in a more extreme 3C temperature rise scenario, and by 135,000 in the case of a 2.2C rise. The total cost of damage would rise from €47.5bn to €66bn in the event of a 3C increase.
Although fewer people would die of cold in the north, that would be more than offset by increased mortality in the south. Under the more extreme scenario of a 3C increase in 2071-2100 relative to 1961-1990, there would be 86,000 additional deaths.

Mist and pollution over the City of London
Carbon dioxide is accumulating in the atmosphere much faster than scientists expected, raising fears that humankind may have less time to tackle climate change than previously thought.
New figures from dozens of measuring stations across the world reveal that concentrations of CO2, the main greenhouse gas, rose at record levels during 2006 - the fourth year in the last five to show a sharp increase. Experts are puzzled because the spike, which follows decades of more modest annual rises, does not appear to match the pattern of steady increases in human emissions.
At its most far reaching, the finding could indicate that global temperatures are making forests, soils and oceans less able to absorb carbon dioxide - a shift that would make it harder to tackle global warming. Such a shift would worsen even the gloomy predictions of the Stern Review which warned that we had little over a decade to tackle rising emissions to avoid the worst effects of climate change.
David Hofmann of the US National Oceanic and Atmospheric Administration (Noaa), which published the figures, said: "Over this last decade the growth rates in carbon dioxide have been higher. I don't think we can plausibly say what's causing it. It's something we're going to look at."
Peter Cox, a climate change expert at Exeter University, said: "The concern is that climate change itself will affect the ability of the land to absorb our emissions." At the moment around half of human carbon emissions are reabsorbed by nature but the fear among scientists is that increasing temperatures will work to reduce this effect.
Professor Cox added: "It means our emissions would have a progressively bigger impact on climate change because more of them will remain in the air. It accelerates the rate of change, so we get it sooner and we get it harder."
Carbon dioxide concentration in the atmosphere is measured in parts per million (ppm). From 1970 to 2000 that concentration rose by about 1.5ppm each year, as human activities sent more of the gas into the atmosphere. But according to the latest figures, last year saw a rise of 2.6ppm. And 2006 was not alone. A series of similar jumps in recent years means the carbon dioxide level has risen by an average 2.2ppm each year since 2001.
Above-average annual rises in carbon dioxide levels have been explained by natural events such as the El Niño weather pattern, centred on the Pacific Ocean. But the last El Niño was in 1998, when it resulted in a record annual increase in carbon dioxide of 2.9ppm. If the current trend continues, this year's predicted El Niño could see the annual rise in carbon dioxide pass the 3ppm level for the first time.
Prof Cox said that an increase in forest fires, heatwaves across Europe and the Amazon drought of 2005 could have helped to drive up carbon dioxide levels. Such events are predicted to become more frequent with rising global temperatures. He admitted "the jury is still out" on whether the recent spike is evidence of a significant change, although some computer models predict that the Earth will start to absorb less carbon dioxide some time this decade.
"Over the past few years carbon dioxide has been going up faster than we would expect, based on the rate that emissions are increasing," Prof Cox said.
Figures presented to a recent UN climate conference in Nairobi showed that carbon dioxide emissions produced by the worldwide burning of fossil fuels increased by 3.2% from 2000 to 2005.
From 1990 to 1999 the emissions increase was 0.8%. But other experts think rising emissions could yet account for the anomaly. Pieter Tans of Noaa cited contrasting figures from the US Department of Energy, which show much sharper annual emissions increases, up to 4.5% in recent years. The Intergovernmental Panel on Climate Change is expected to announce more robust emissions data when it reports next month.

Logging trees in a Swedish forest, as seen from the air
The photograph was taken by a Swede named Jocke Berglund, and it won him a Wildlife Photographer of the Year award from London's Natural History Museum, on whose site the following elucidation is offered:
When Hurricane Gudrun thundered across southern Sweden in January 2005, it left around 100,000 people isolated and without electricity. Deep snow, fallen trees and severe temperatures meant several people died before help could reach them. Flying over Småland photographing the devastation, Jocke — who specializes in aerial photography — saw this 'remarkable oak tree print'. It was formed partly by the storm brush of nature and partly by the impact on the soil of the forestry machines retrieving logs. 'It's as if the heavens had sent a message to the forest industry reminding them that, in this area, deciduous trees would have withstood the winds much better than pine. It's also another stark reminder that global warming will lead to regular and stronger storm winds.'

now that is an amazing picture!
Anways, all people should think about the consequences of environment pollution and global warming. What future will humans have if nothing is done short term?
