The 20 questions

  1. What is a trend in data?

    • The total of all the values added together.
    • A single value that sits far outside the rest of the data.
    • The overall direction the data moves over time, ignoring small wobbles.
    • The place where a data set was first collected.

  2. What is an anomaly on a graph?

    • The label that names the axis of the graph.
    • A point that sits well above or below the general pattern.
    • The overall direction of the line from start to end.
    • The average value across all the years shown.

  3. In percentage change, which value is the calculation divided by?

    • The two values added together.
    • The largest value in the data set only.
    • The start value.
    • The end value.

  4. What was the UK's record temperature recorded on 19 July 2022?

    • 35.3 degrees Celsius.
    • 45.3 degrees Celsius.
    • 30.0 degrees Celsius.
    • 40.3 degrees Celsius.

  5. Which official body collects UK weather data?

    • The Royal Geographical Society.
    • A local council's planning department.
    • The Met Office.
    • The National Trust.

  6. Hot days rose from 4 in the 1960s to 14 in the 2010s. What is the percentage change?

    • An increase of 1000 percent.
    • An increase of 10 percent.
    • An increase of 250 percent.
    • An increase of 40 percent.

  7. A value rises from 20 to 25. What is the percentage change?

    • An increase of 25 percent.
    • An increase of 45 percent.
    • An increase of 20 percent.
    • An increase of 5 percent.

  8. A value falls from 50 to 40. What is the percentage change?

    • A decrease of 10 percent.
    • A decrease of 25 percent.
    • A decrease of 20 percent.
    • A decrease of 40 percent.

  9. Rainfall fell from 1300 mm to 1010 mm. Roughly what is the percentage change?

    • A decrease of about 29 percent.
    • A decrease of about 22 percent.
    • An increase of about 22 percent.
    • A decrease of about 13 percent.

  10. On the UK rainfall line from 2015 to 2023, which year is the clearest dry anomaly?

    • 2015, at about 1180 mm.
    • 2023, at about 1330 mm.
    • 2019, at about 1280 mm.
    • 2022, at about 1010 mm.

  11. Why is one hot summer not enough to show that the climate is changing?

    • Hot summers never happen in the UK, so the evidence is useless.
    • One summer is always cooler than the next, so it cannot be compared.
    • Only the Met Office can judge one summer, so it is not valid evidence.
    • One summer is weather, and climate needs a long average of 30 years or more.

  12. Why does a warmer atmosphere tend to cause heavier rainfall?

    • Warmer air is denser, so it pushes rain down faster.
    • Warmer air blocks sunlight from the ground, so rain falls more often and lasts longer.
    • Warmer air holds more water vapour, so storms can release more rain.
    • Warmer air stops clouds from forming at all.

  13. Which is the best description of the heavy-rain index trend (100 in the 1960s to 132 in the 2020s)?

    • Heavy-rain days fall sharply from 100 to 32 across the decades.
    • Heavy-rain days rise only in the 1970s, then drop back to zero by the 2020s across the decades.
    • Heavy-rain days rise steadily, from an index of 100 in the 1960s to 132 in the 2020s.
    • Heavy-rain days stay the same at 100 throughout all of the decades.

  14. What is the percentage change from an index of 100 to an index of 132?

    • An increase of 68 percent.
    • An increase of 3.2 percent.
    • An increase of 32 percent.
    • An increase of 132 percent.

  15. A pupil says 'the UK is getting hotter because this year was hot'. What is the best correction?

    • One hot year is weather; a long-term rising trend over many years is needed to show climate change.
    • Hot years only happen in summer, so they cannot show climate change at all.
    • Only the sea can show climate change, not land temperatures, since land readings are always far too unreliable.
    • The pupil is right, because any single hot year proves climate change at once.

  16. Which source is most trustworthy for UK weather data?

    • The Met Office's long-running station records.
    • A single social media post from a stranger.
    • An unsourced blog that gives no dates or methods.
    • A rumour passed round a school playground.

  17. Which feature of data provenance matters most when judging a trend?

    • How long the record is, and whether the stations and methods stayed consistent.
    • How many people shared and liked the graph online, and whether the newspaper that printed it was popular.
    • The font size used in the title of the chart.
    • The colour the publisher used to draw the graph, and whether the same colours were used for each decade.

  18. Which conclusion from the 2015 to 2023 rainfall line is most justified?

    • 2022 is a wet anomaly, because 1010 mm is a high amount of rain.
    • 2022 is a dry anomaly, but one year does not change the overall pattern on its own.
    • All the years from 2015 to 2023 are identical, so there is no anomaly.
    • 2022 proves the UK is becoming drier in every single year.

  19. Why does the heavy-rain index not, on its own, prove that UK weather is more extreme?

    • Index values are always wrong, so geographers can never use them.
    • The index only covers Scotland, so it cannot apply to the whole UK.
    • Heavy rain is never extreme in any region, so the index cannot show extremes at all, whatever its source.
    • It is one measure set as an index, so you must check its source and the length of the record.

  20. Which is the stronger evidence that the climate is changing?

    • A single record-breaking day in one summer.
    • A long-term rising trend across many decades.
    • A single cold winter following a warm summer.
    • One unusually wet month in a single region.
