The World in Winter

The World in Winter is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand The World in Winter rather than just read about it. In short: The World in Winter (US title The Long Winter) is a 1962 post-apocalyptic science fiction novel by British writer John Christopher. It deals with a new ice age caused by a reduction in the output of the Sun.

Key takeaways

  • The World in Winter belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect The World in Winter to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of The World in Winter from memory before moving on to harder problems.

Reference excerpt

The World in Winter (US title The Long Winter) is a 1962 post-apocalyptic science fiction novel by British writer John Christopher. It deals with a new ice age caused by a reduction in the output of the Sun.

Plot summary The story involves a new ice age hitting Europe, British refugees fleeing to Nigeria, and what a later group find when they return. As the story opens, Andrew Leedon, a London-based television documentary producer, is given a new story to research: an Italian scientist, Fratellini, has proposed an imminent fall in solar radiation for the forthcoming few years which may lead to harsher winters. Leedon meets with David Cartwell, a Home Office civil servant and useful source, to see if he can find out more. Cartwell quickly becomes a close friend of Leedon, but also begins an affair with Leedon's wife, Carol. The winter of that year is, as predicted, long and harsh, but by January is it becoming clear to insiders that the solar downturn is worse than Fratellini had calculated and no upturn is in sight. By March, food stocks are becoming dangerously low, rationing has been imposed and the Government imposes martial law. Those in the know, including Andrew's estranged wife, sell up and move south to the tropics and countries such as Nigeria. Leedon stays behind, as inner London is finally cordoned off from the rest of the UK to protect the seat of power – an area called the London Pale – as the rest of the country is abandoned to starvation and barbarism. Finally Leedon is persuaded both by Carol and by David Cartwell to exit the country while safe passage is still possible. Taking with him Cartwell's wife Madeleine, he moves to Lagos in Nigeria, finding that the tables have now turned – white refugees fleeing from the ice-bound northern countries are living in slums, unemployed or with only menial jobs, and penniless, as African governments have withdrawn recognition of currencies such as Sterling and no longer recognize the British Government, with reason, as it no longer exercises sovereignty over its own land. A ray of hope arrives for Leedon as Abonitu, a young Nigerian whom Leedon had treated with kindness and generosity one evening in London, finds him and in turn helps him and Madeleine out of the slum. Abonitu plans a reconnaissance expedition back to Britain.

Worked examples

Example 1 — a first encounter with The World in Winter

Start with the simplest possible case. Write down what The World in Winter claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to The World in Winter before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about The World in Winter ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of The World in Winter

In research
The World in Winter appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses The World in Winter in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
The World in Winter is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1960s science fiction novel stubs, 1962 British novels, 1962 English-language novels, so understanding it makes those chapters shorter.
In everyday life
Look for The World in Winter outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
