It's so ironic. It is said that the countries that pump most of the
greenhouse gasses into the atmosphere are the ones that are expected
to suffer least from global warming.

"You have to hand it to the economics team at Goldman Sachs. It was
they who came up with the concept of the "BRICs'': the four big
economies, in Brazil, Russia, India and China, that were going to
catch up with and then overtake the big economies of the developed
world. More recently they added the "Next Eleven'': middle-sized
developing countries like Turkey, Indonesia and Mexico that will also
grow fast enough to overtake their old-rich counterparts in the next
generation.

Back in 2006, Goldman Sachs predicted that the Chinese economy would
surpass that of the United States in the early 2040s, with the Indian
economy not far behind. But now the Goldman Sachs team has put out a
new set of forecasts.

The Chinese economy, they predict, will overtake the US economy around
2025, not in the 2040s, and will be twice as big by 2050. India's
economy by 2050 will still be slightly smaller than that of the United
States, but the economies of Brazil, Russia, Indonesia and Mexico will
all be bigger than that of the next-largest old-rich country, Britain.

The changes in the pecking order are equally dramatic further down.
Turkey's economy in 2050 will be bigger than Japan's, France's or
Germany's, and both Nigeria and the Philippines will have larger
economies than Canada and Italy. Korea, Iran and Saudi Arabia will all
have bigger economies than Spain.

The predicted changes in per capita income by 2050 are less radical,
though still impressive. The United States and the United Kingdom are
neck-and-neck at the top, just as they are now, with Canada only
slightly behind. Koreans are substantially richer than Japanese-
US$80,000 per annum versus US$63,000 - and the Chinese still bring up
the rear in East Asia with a mere US$50,000 a year.

But hang on a minute. Fifty thousand dollars a year is slightly higher
than the present per capita income in the US or Britain. In 2050 there
will be around one and a half billion Chinese, and if they have an
average per capita income of US$50,000 a year then most of them will
be leading a fairly lavish middle-class lifestyle. How is this
compatible with what we know about the world's resources of energy,
food and other commodities, and about the likely course of climate
change?

Goldman Sachs is providing surprise-free projections of current
trends. This is a useful exercise, because it sets the larger
framework in which the inevitable surprises will take place. But that
is all it is, because no 40-year stretch of history is free of
surprises.

In the past 40 years we have seen the rise to great wealth of the
oil-exporting states of the Arabian peninsula, but a crash in the
predicted Iranian growth rate after the 1979 revolution. We have seen
the disappointment of the high expectations most people held for newly
independent African countries in the 1960s, and the sudden high growth
rates of most Asian countries in the 1980s and 1990s. We have seen the
collapse of the Soviet empire and the expansion of the European Union
into Eastern Europe.

Few economic analysts in 1968 predicted any of this, any more than
they foresaw globalisation, the internet or the rise of the euro.
History does not run on rails, and none of those things was certain to
happen (though some had a much higher probability of happening than
others). The same applies to the relationship between the present and
the future: Goldman Sachs is offering us a point of departure for
thinking about the future, not a map of it.

So what are some of the things that could derail this simple picture
of a richer future in which the gap between rich and poor has narrowed
sharply except for Africa? A mere shortage of oil or other commodities
wouldn't change the pecking order much, although it might lower
everybody's average income (except in the commodity-exporting
countries).

Local political upheavals might knock specific countries out of the
running, like Iran in the 1980s or Russia in the 1990s, but that
wouldn't change the broader picture either.

The one "known unknown'' that could do that is large-scale climate
change, because it would strike some countries much harder than
others, at least in the early phase. And the hardest-hit countries
would include most of those that are now climbing rapidly in the
rankings.

Countries in the tropics and the sub-tropics are likely to be hit
early and hard by climate change, while most of those in the temperate
climate zone will suffer relatively little until a good deal later in
the process. Countries like Turkey, Mexico, Indonesia, India and Iran
will suffer diminished rainfall and declining food production, and
even China, although mostly in the temperate zone, will struggle as
the glaciers on the Tibetan plateau that feed most of its major rivers
melt away.

Since the countries that suffer least, like the US, Canada, Britain,
France, Germany, Russia and Japan, are also the ones that produced
most of the greenhouse-gas emissions that have caused the current
warming, this will probably result in some very bitter exchanges
between North and South. But it also means that the economic pecking
order in 2050 may be less different from today's than Goldman Sachs
predicts."
