Apocalypse Now: How Mankind is Sleepwalking to the End of the Earth

(Yes, it is a repost, but it is so damned important it must be done.)
Floods, storms and droughts. Melting Arctic ice, shrinking glaciers, oceans turning to acid. The world's top scientists warned last week that dangerous climate change is taking place today, not the day after tomorrow. You don't believe it? Then, says Geoffrey Lean, read this...
(Rhetorical question - What the hell is next? Will the time come that we must take up arms to save the earth?)

Future historians, looking back from a much hotter and less hospitable world, are likely to play special attention to the first few weeks of 2005. As they puzzle over how a whole generation could have sleepwalked into disaster - destroying the climate that has allowed human civilization to flourish over the past 11,000 years - they may well identify the past weeks as the time when the last alarms sounded.

Last week, 200 of the world's leading climate scientists - meeting at Tony Blair's request at the Met Office's new headquarters at Exeter - issued the most urgent warning to date that dangerous climate change is taking place, and that time is running out.

Next week the Kyoto Protocol, the international treaty that tries to control global warming, comes into force after a seven-year delay. But it is clear that the protocol does not go nearly far enough.

The alarms have been going off since the beginning of one of the warmest Januaries on record. First, Dr Rajendra Pachauri - chairman of the official Intergovernmental Panel on Climate Change (IPCC) - told a UN conference in Mauritius that the pollution which causes global warming has reached "dangerous" levels.

Then the biggest-ever study of climate change, based at Oxford University, reported that it could prove to be twice as catastrophic as the IPCC's worst predictions. And an international task force - also reporting to Tony Blair, and co-chaired by his close ally, Stephen Byers - concluded that we could reach "the point of no return" in a decade.

Finally, the UK head of Shell, Lord Oxburgh, took time out - just before his company reported record profits mainly achieved by selling oil, one of the main causes of the problem - to warn that unless governments take urgent action there "will be a disaster".

But it was last week at the Met Office's futuristic glass headquarters, incongruously set in a dreary industrial estate on the outskirts of Exeter, that it all came together. The conference had been called by the Prime Minister to advise him on how to "avoid dangerous climate change". He needed help in persuading the world to prioritize the issue this year during Britain's presidencies of the EU and the G8 group of economic powers.

The conference opened with the Secretary of State for the Environment, Margaret Beckett, warning that "a significant impact" from global warming "is already inevitable". It continued with presentations from top scientists and economists from every continent. These showed that some dangerous climate change was already taking place and that catastrophic events once thought highly improbable were now seen as likely (see panel). Avoiding the worst was technically simple and economically cheap, they said, provided that governments could be persuaded to take immediate action.

About halfway through I realized that I had been here before. In the summer of 1986 the world's leading nuclear experts gathered in Vienna for an inquest into the accident at Chernobyl. The head of the Russian delegation showed a film shot from a helicopter, and we suddenly found ourselves gazing down on the red-hot exposed reactor core.

It was all, of course, much less dramatic at Exeter. But as paper followed learned paper, once again a group of world authorities were staring at a crisis they had devoted their lives to trying to avoid.

I am willing to bet there were few in the room who did not sense their children or grandchildren standing invisibly at their shoulders. The conference formally concluded that climate change was "already occurring" and that "in many cases the risks are more serious than previously thought". But the cautious scientific language scarcely does justice to the sense of the meeting.

We learned that glaciers are shrinking around the world. Arctic sea ice has lost almost half its thickness in recent decades. Natural disasters are increasing rapidly around the world. Those caused by the weather - such as droughts, storms, and floods - are rising three times faster than those - such as earthquakes - that are not.

We learned that bird populations in the North Sea collapsed last year, after the sand eels on which they feed left its warmer waters - and how the number of scientific papers recording changes in ecosystems due to global warming has escalated from 14 to more than a thousand in five years.

Worse, leading scientists warned of catastrophic changes that once they had dismissed as "improbable". The meeting was particularly alarmed by powerful evidence, first reported in The Independent on Sunday last July, that the oceans are slowly turning acid, threatening all marine life.

Professor Chris Rapley, director of the British Antarctic Survey, presented new evidence that the West Antarctic ice sheet is beginning to melt, threatening eventually to raise sea levels by 15ft: 90 per cent of the world's people live near current sea levels. Recalling that the IPCC's last report had called Antarctica "a slumbering giant", he said: "I would say that this is now an awakened giant."

Professor Mike Schlesinger, of the University of Illinois, reported that the shutdown of the Gulf Stream, once seen as a "low probability event", was now 45 per cent likely this century, and 70 per cent probable by 2200. If it comes sooner rather than later it will be catastrophic for Britain and northern Europe, giving us a climate like Labrador (which shares our latitude) even as the rest of the world heats up: if it comes later it could be beneficial, moderating the worst of the warming.

The experts at Exeter were virtually unanimous about the danger, mirroring the attitude of the climate science community as a whole: humanity is to blame. There were a few skeptics at Exeter, including Andrei Illarionov, an adviser to Russia's President Putin, who last year called the Kyoto Protocol "an interstate Auschwitz". But in truth it is much easier to find skeptics among media pundits in London or neo-cons in Washington than among climate scientists. Even the few contrarian climatalogists publish little research to support their views, concentrating on questioning the work of others.

Now a new scientific consensus is emerging - that the warming must be kept below an average increase of two degrees centigrade if catastrophe is to be avoided. This almost certainly involves keeping concentrations of carbon dioxide, the main cause of climate change, below 400 parts per million.

Unfortunately we are almost there, with concentrations exceeding 370ppm and rising, but experts at the conference concluded that we could go briefly above the danger level so long as we brought it down rapidly afterwards. They added that this would involve the world reducing emissions by 50 per cent by 2050 - and rich countries cutting theirs by 30 per cent by 2020.

Economists stressed there is little time for delay. If action is put off for a decade, it will need to be twice as radical; if it has to wait 20 years, it will cost between three and seven times as much.

The good news is that it can be done with existing technology, by cutting energy waste, expanding the use of renewable sources, growing trees and crops (which remove carbon dioxide from the air) to turn into fuel, capturing the gas before it is released from power stations, and - maybe - using more nuclear energy.

The better news is that it would not cost much: one estimate suggested the cost would be about 1 per cent of Europe's GNP spread over 20 years; another suggested it meant postponing an expected fivefold increase in world wealth by just two years. Many experts believe combating global warming would increase prosperity, by bringing in new technologies.

The big question is whether governments will act. President Bush's opposition to international action remains the greatest obstacle. Tony Blair, by almost universal agreement, remains the leader with the best chance of persuading him to change his mind.

But so far the Prime Minister has been more influenced by the President than the other way round. He appears to be moving away from fighting for the pollution reductions needed in favor of agreeing on a vague pledge to bring in new technologies sometime in the future.

By then it will be too late. And our children and grandchildren will wonder - as we do in surveying, for example, the drift into the First World War - "how on earth could they be so blind?"

WATER WARS

What could happen? Wars break out over diminishing water resources as populations grow and rains fail.

How would this come about? Over 25 per cent more people than at present are expected to live in countries where water is scarce in the future, and global warming will make it worse.

How likely is it? Former UN chief Boutros Boutros-Ghali has long said that the next Middle East war will be fought for water, not oil.

DISAPPEARING NATIONS

What could happen? Low-lying island such as the Maldives and Tuvalu - with highest points only a few feet above sea-level - will disappear off the face of the Earth.

How would this come about? As the world heats up, sea levels are rising, partly because glaciers are melting, and partly because the water in the oceans expands as it gets warmer.

How likely is it? Inevitable. Even if global warming stopped today, the seas would continue to rise for centuries. Some small islands have already sunk for ever. A year ago, Tuvalu was briefly submerged.

FLOODING

What could happen? London, New York, Tokyo, Bombay, many other cities and vast areas of countries from Britain to Bangladesh disappear under tens of feet of water, as the seas rise dramatically.

How would this come about? Ice caps in Greenland and Antarctica melt. The Greenland ice sheet would raise sea levels by more than 20ft, the West Antarctic ice sheet by another 15ft.

How likely is it? Scientists used to think it unlikely, but this year reported that the melting of both ice caps had begun. It will take hundreds of years, however, for the seas to rise that much.

UNINHABITABLE EARTH

What could happen? Global warming escalates to the point where the world's whole climate abruptly switches, turning it permanently into a much hotter and less hospitable planet.

How would this come about? A process involving "positive feedback" causes the warming to fuel itself, until it reaches a point that finally tips the climate pattern over.

How likely is it? Abrupt flips have happened in the prehistoric past. Scientists believe this is unlikely, at least in the foreseeable future, but increasingly they are refusing to rule it out.

RAINFOREST FIRES

What could happen? Famously wet tropical forests, such as those in the Amazon, go up in flames, destroying the world's richest wildlife habitats and releasing vast amounts of carbon dioxide to speed global warming.

How would this come about? Britain's Met Office predicted in 1999 that much of the Amazon will dry out and die within 50 years, making it ready for sparks - from humans or lightning - to set it ablaze.

How likely is it? Very, if the predictions turn out to be right. Already there have been massive forest fires in Borneo and Amazonia, casting palls of highly polluting smoke over vast areas.

THE BIG FREEZE

What could happen? Britain and northern Europe get much colder because the Gulf Stream, which provides as much heat as the sun in winter, fails.

How would this come about? Melting polar ice sends fresh water into the North Atlantic. The less salty water fails to generate the underwater current which the Gulf Stream needs.

How likely is it? About evens for a Gulf Steam failure this century, said scientists last week.

STARVATION

What could happen? Food production collapses in Africa, for example, as rainfall dries up and droughts increase. As farmland turns to desert, people flee in their millions in search of food.

How would this come about? Rainfall is expected to decrease by up to 60 per cent in winter and 30 per cent in summer in southern Africa this century. By some estimates, Zambia could lose almost all its farms.

How likely is it? Pretty likely unless the world tackles both global warming and Africa's decline. Scientists agree that droughts will increase in a warmer world.

ACID OCEANS

What could happen? The seas will gradually turn more and more acid. Coral reefs, shellfish and plankton, on which all life depends, will die off. Much of the life of the oceans will become extinct.

How would this come about? The oceans have absorbed half the carbon dioxide, the main cause of global warming, so far emitted by humanity. This forms dilute carbonic acid, which attacks corals and shells.

How likely is it? It is already starting. Scientists warn that the chemistry of the oceans is changing in ways unprecedented for 20 million years. Some predict that the world's coral reefs will die within 35 years.

DISEASE

What could happen? Malaria - which kills two million people worldwide every year - reaches Britain with foreign travelers, gets picked up by British mosquitos and becomes endemic in the warmer climate.

How would this come about? Four of our 40 mosquito species can carry the disease, and hundreds of travelers return with it annually. The insects breed faster, and feed more, in warmer temperatures.

How likely is it? A Department of Health study has suggested it may happen by 2050: the Environment Agency has mentioned 2020. Some experts say it is miraculous that it has not happened already.

HURRICANES

What could happen? Hurricanes, typhoons and violent storms proliferate, grow even fiercer, and hit new areas. Last September's repeated battering of Florida and the Caribbean may be just a foretaste of what is to come, say scientists.

How would this come about? The storms gather their energy from warm seas, and so, as oceans heat up, fiercer ones occur and threaten areas where at present the seas are too cool for such weather.

How likely is it? Scientists are divided over whether storms will get more frequent and whether the process has already begun.

politics as impossible

"(Rhetorical question - What the hell is next? Will the time come that we must take up arms to save the earth?)"

Armed conflict within the population of the U.S.A. can only occur in the context of a general breakdown of the government. We tend to think anarchist about that prospect and say "Good!" However, consider the breakdown of the old Soviet Union: what was the result for environmental issues? Answer: DISASTER. Whatever was bad got worse; the positive aspects of socialism were sacrificed in order to retain the negative aspects of the Stalinist police-state. That is the problem with pushing for the breakdown of governmental control: corporate power and greed take over. Where the old fascist (or, in the case of the U.S.S.R., the old Stalinist) government was, corporate crime syndicates, "mafias," fill the gap. There is even less ability to deal with planetary environmental disaster.

We are at this time in a situation that carpenters describe as "two-blocked" -- no way forward, no way back. Even the Green Anarchists have abandoned, in effect, any effort toward social change: rather, they advise preparing ourselves in small "tribal" units for the coming post-modern Stone Age. It is aptly termed in the title of the post presenting this article, "Sleepwalking."

Or am I wrong? Anyone out there able to post a comment here about what ordinary citizens can do to advance the people of Earth out of this morass? On the other hand, I expect there are many with programs that are essentially separatist -- how maybe you and a few friends ("comrades"?) can become leaders among the surviving remnants of civilization.

(Rhetorical question: do I, "politics as impossible," have the answer? -- or am I able to present any positive program at all?)

spyder eye

i'm less inclined to focus on the nuts and bolts of the issues ( this view is important
just not my inclination} and step back abit. iwill post something soon , would like your comment.

hanford, the other tsunami 08.Feb.2005 10:10

wiped out

it is very tragic that the average citizen is the morass. people are stagnant or only sink deeper when facing such horrendous disasters. throwing money at the problem doesn't heal the situation, but people want to believe that it does, the media says so. hanford is just one example of how shellshocked average citizens are. citizens want to believe they are providing for their children's future, working hard to put food on the table, a roof over their heads, college, vacation time, and fun. meanwhile the heavy, heavy issuess overwhelm the citizen and keep them under the whip, and in fantasy land. the profiteers hold the whip, and they are suicidal, and take the planet with them. it would be a miricle if the average citizen could break free and stop fueling flame throwers, realizing their potential, ie prioritizing; what is the basic necessity for survival in such rapidly changing times? without the average citizen leaving this enslaving culture, hanford will continue to flow underground, and flow deep within the sub-conscience. reality is to scarey, this keeps the citizen in thier geni bottle, and when they come out, their master says, "just look on the brightside of life", "there are many opportunities to make this a better world", "get a worthy career in social justice or environmental protection", "you can make a difference" in effect becoming an average citizen. and hanford spreads. i am staying at a friends place who has a one-eyedtechnocolur-god and flipping thrugh we came upon 20/20 or somethin like that, talking about how sharing is bad, and even dangerous- using examples of public places and such. our culture is doomed, money is competition, competition is human decline. what do i do? i pray to god, creater of heaven and earth, the giver of life in the name of jesus christ. a lot of average citizens say this, but really aren't allowed to do so. for if they did they would no longer be average citizens. change starts from god and that change begins inside, and manifests outward. idon't believe the world will stop its present course, but i dont't have to participate in destroying it. i reach for a more pure conscienceness, because the death of this world cannot destroy the life that was given to us. there is more to life than what we can see in this universe.
