Visualizing the great acceleration

A visualization of the great acceleration from the Encyclopedia of the Earth article Evolution of the human-environment relationship by Costanza and others.


Figure 1. Selected indicators of environmental and human history.

While this depiction of past events is integrative and suggestive of major patterns and developments in the human-environment interaction, it plots only coincidence, not causation, and must, of course, be supplemented with integrated models and narratives of causation.

In this graph, time is plotted on the vertical axis on a log scale running from 100,000 years before present (BP) until now. Technological events are listed on the right side and cultural/political events are listed on the left.

Biologically modern humans arose at least 100,000 yrs BP and probably more than 200,000 – 250,000 yrs BP, but sedentism (and later agriculture) did not start until after the end of the last ice age and the dramatic warming and stabilization of climate that occurred around 10,000 yrs BP, at the Pleistocene/Holocene boundary.

Northern Hemisphere temperature can be reconstructed for this entire period from ice core data, combined with the instrument record from 1850 until the present.

Human population fluctuated globally at around 1 million until the advent of agriculture, after which it began to increase exponentially (with some declines as during the black death in Europe) to a current population of over 6 Billion.

Gross World Product (GWP) followed with some lag as people tapped new energy sources such as wind and eventually fossil fuels.

Atmospheric carbon dioxide (CO2) and methane (CH4) closely track population, GWP and energy use for the last 150 years.

The start of the “Great Acceleration” after WWII can be clearly seen in the GWP, population, and water withdrawal plots.

The plot for “SE Asian Monsoons” shows the long-term variability in this important regional precipitation pattern.

Patterns in land use are shown as the fraction of land in forest, cropland, and in the “three largest polities”. This area in large “polities” or sovereign political entities has increased over time, with significant peaks at the height of the Roman, Islamic Caliphate, Mongol, and British empires. Currently the three largest polities are Russia, Canada, and China, together covering about 32% of the land surface. At the peak of the British empire in 1925, the 3 largest were Britain, Russia, and France, together covering about 53% of the land surface before the independence of British and French colonies.

Wine and climate change in the UK

Richard Selley an Emeritus Professor at Imperial College London has written a book The Winelands of Britain: past, present and prospective, that describes how climate, geology, and culture have shaped wine growing in the UK.

He projects that climate change will destroy the wine producing potential of current wine producing areas of the UK, such as the Thames Valley, and the Severn valley. From an Imperial college press release:

…if the climate changes in line with predictions by the Met Office’s Hadley Centre, by 2080 vast areas of the UK including Yorkshire and Lancashire will be able to grow vines for wines like Merlot and Cabernet Sauvignon which are currently only cultivated in warmer climates like the south of France and Chile.

Different grape varieties flourish in different temperatures, and are grouped into cool, intermediate, warm and hot grape groups. For the last 100 years ‘cool’ Germanic grape varieties have been planted in British vineyards to produce wines like Reisling. In the last 20 years some ‘intermediate’ French grape varieties have been successfully planted in southeast England, producing internationally prize-winning sparkling white wines made from Pinot Noir, Pinot Meunier and Chardonnay.

Combining temperature predictions from the IPCC and the Met Office’s Hadley Centre with his own research on UK vineyards throughout history, Professor Selley predicts that these cool and intermediate grape varieties will be confined to the far north of England, Scotland and Wales by 2080, with ‘warm’ and ‘hot’ varieties seen throughout the midlands and south of England.

Explaining the significance of his new study, Emeritus Professor Selley from Imperial’s Department of Earth Science and Engineering, said: “My previous research has shown how the northernmost limit of UK wine-production has advanced and retreated up and down the country in direct relation to climatic changes since Roman times.

“Now, with models suggesting the average annual summer temperature in the south of England could increase by up to five degrees centigrade by 2080, I have been able to map how British viticulture could change beyond recognition in the coming years. Grapes that currently thrive in the south east of England could become limited to the cooler slopes of Snowdonia and the Peak District.”

A climate change and development slide show

The 2007/2008 UN Human Development Report Fighting climate change: Human solidarity in a divided world focuses on the inequalities of climate change, as well as providing its usual indicators of human development.

According to the report, in 2007 the most developed countries are Iceland, Norway, Australia, Canada, and Ireland while the least developed (of the countries ranked) are Mali, Niger, Guinea-Bissau, Burkina Faso, and Sierra Leone).

The high developed countries are responsible most of the accumulation of greenhouse gases driving climate change, while the low development countries are most vulnerable to the impacts of climate change (see also previous post on climate inequalities).

Now the report has inspired an exhibit at the UN – One planet, one chance. Magnum photos produced a video for the exhibit, which uses gripping photos to describes the basic inequalities of climate change. The video is below the break.

Shipping containers and world trade

The BBC is planning to follow and report on the progress of a container around the world for a year.  They have painted a container and bolted a GPS transmitter to allow is readers to follow its progress around the world on their map (as I write this the container full of whiskey in Scotland).

The BBC named their project The Box after The Box: How the Shipping Container Made the World Smaller and the World Economy Bigger an interesting book on the history of containerization and its effect on globalization by Marc Levinson (here is a book review from Ethan Zuckerman and an essay by Witold Rybczynski).

I read the book earlier this year and enjoyed it.  I would have liked more economic history and statistics in the book, but its main problem was that people mocked me when I told them I was reading a book about containers. However, containers have become an essential part of global trade and of its rapid growth.

Below are some maps of parts of global trade.  They give a bit of an idea of where such a container is likely to move between.

The book – The Box – includes lots of interesting history of the container system, and how as a system it lead to innovations, efficiencies, and had many unintendend consequences.  One example, is that it made many old ports obsolete which reshaping many city centres (over decades), but also the creation of new ports and the changes in container ships they triggered – caused ongoing shifts in global trade patterns.

One key cycle of change was a postive feedback between ship size and port attributes. Because the fuel consumption of a ship does not increase proportionately to the number of containers a ship can carry – containers ships have become bigger and bigger – which has had the effect of focusing trade into ports that can handle the large ships and the trade volume.  These big ports then lead to the construction of more bigger ships. Wikipedia lists the world’s busiest container ports – the top are Singapore, Shanghai, Hong Kong , Shenzen, and Busan.  This concentration of big ships in big ports has had the effect of making world trade unexpectedly (for economic theory) “lumpy.”  Paul Krugmann explains:

[Economic theory suggests] a country like China should export a wider range of products to a small country, like Ecuador, than it does to a big country, like the US. Why? Because Ecuador, being small, probably has fewer industries that are cost-competitive with Chinese exports. In fact, however, China seems to export a wider range of stuff to bigger economies.

A possible explanation is the lumpiness of transport costs: there are more container ships heading from China to US ports than to Ecuadorian ports, so that it’s worth sending over a bigger range of stuff. It’s like the reason there are fewer food choices in supermarkets on St. Croix (where we spent our last vacation) than in New Jersey — there’s just one boat with groceries coming over every once in a while, so you can’t keep, um, arugula in stock.

Reading the Box also makes it clear that while higher fuel prices will reshape trade patterns and probably boat designs, neither global trade patterns nor transportation costs will return to those of the 1960s or 1970s.  This is due to huge improvements in logistics that have radically dropped the labour cost for shipping goods long distances, and this has also decreased fuel costs.

The rapid expansion of skills in logistics is a hidden environmental efficiency of the moden world economy – in that it allows things to be moved around for less cost than earlier in history.  However as occurs with most increases in efficiency, modern society undoes the environmental advantages of efficiency by using the cost saving to simply move more stuff for the same amount of money.

Logistics makes at least parts of the world “flatter.” And the ease of making these connections appears to make it easier to spread tools and ideas as well as goods.  The World Bank claims that countries with the most predictable, efficient, and best-run transportation routes and trade procedures are also the most likely to take advantage of technological advances, economic liberalization, and access to international markets.  While countries with higher logistics costs are more likely to miss the opportunities of globalization.  The World Bank ranks countries using a logistics performance index which measures the ease with which the country connects to the global economy.  Singapore, Netherlands, and Germany are at the top as the most accessible; while Rwanada, East Timor, and Afghanistan are at the bottom of the rankings.

Of course, novel solutions also produce novel problems.  Discarded containers litter landscapes worldwide (finding uses for them has become a standard architecture project), container ports are centres of environmental and biotic pollution, and the ease of using containers is also useful for smuggling.

And at least my impression from reading The Box, was that containerization has not finished trasnforming the world economy.

P.S. Ethan Zuckerman also has a long post Mapping a connected world discussing containers and world trade.

A transforming Arctic

Arctic sea ice, Sept 8, 2008 (From NASA EO).

From EO Newsroom

This image shows Arctic sea ice concentration on September 8, 2008, as observed by the Advanced Microwave Scanning Radiometer–Earth Observing System (AMSR-E) sensor on NASA’s Aqua satellite. The observations are collected on a pixel by pixel basis over the Arctic. The percentage of a 12.5-square-kilometer pixel covered by ice is shown in shades of dark blue (no ice) to white (100 percent ice). The gray line around the Arctic basin shows the median minimum extent of sea ice from 1979-2000. (The median of a data set is the middle value if you arrange the numbers in order from smallest to largest.)

The southern portions of the Northwest Passage through the Arctic (the western route from Europe to Asia through the islands of northern Canada) opened in early August. Then in early September, ice scientists confirmed that the waters around the Russian coastline—the Northern Sea Route— were navigable, but still treacherous, with shifting floes of thick, multi-year ice, that could coalesce rapidly. The image shows that the widest avenue through the Northwest Passage, Parry Channel, still harbored some ice, but the more circuitous, southern waterways were clear. On the other side of the Arctic Ocean, the passage around Russia’s Taymyr Peninsula, normally locked in by ice, was similarly open. According to a press release from the U.S. National Ice Center, “This is the first recorded occurrence of the Northwest Passage and Northern Sea Route both being open at the same time.”

The summer opening of the Arctic means that new uses of the Arctic are likely to emerge. International legal experts believe that “existing laws governing everything from fish stocks to bio-prospecting by pharmaceutical companies” are inadequate.

To date, the eight Arctic nations (the United States, Russia, Canada, Norway, Sweden, Iceland, Denmark and Finland) have limited discussions to existing agreements, such as the law of the sea. Environmental groups would like new laws, but others have suggested a more feasible, and adaptive response may be to strengthen the role of the existing Arctic Council to better govern a changing Arctic in a more adaptive way.

UK energy flow chart 2007

From the UK’s Department of Business Enterprise and Regulatory Reform

UK Energy Flow Chart

It is based on statistics taken from the Digest of United Kingdom Energy Statistics 2008, Table 1.1 – Energy Balance 2007. The flow chart is a simplification of these figures, illustrating the flow of primary fuels from the point at which they become available from home production or imports (on the left) to their eventual final uses (on the right). They are shown in their original state and after being converted into different kinds of energy by the secondary fuel producers. The flows are measured in million tonnes of oil equivalent, with the widths of the bands approximately proportional to the size of the flow they represent.

More detailed flow charts are available by fuel on the BERR website.
