You know that the ice caps are melting, the seasons are changing, sea levels are rising, storms are on the increase, but what can you do about it?
This book puts the power back into your hands in the face of the doom and gloom of climate change. Climate Change: Simple Things You Can Do to Make a Difference is packed with ideas for action, from simple everyday things that cost nothing to bigger projects that involve more time and money. The 'Climate through time' poster shows the rocks of Britain and Ireland grouped and coloured according to the environment under which they were formed.
Each oval in the key also contains an illustration of a modern-day rock-forming environment alongside an image of a typical rock-type laid down under those environmental conditions — this provides evidence for the existence of the environment in the geological past. Such rocks can be found today across Ireland, the Peak District and the North and South Downs. The key tells us that at one time, the environment of this area alternated between warm seas and tropical swamps — the sandstones, limestones and coal which are found in southern England today tell us of the past environments which affected the types of rocks which were laid down in the distant past.
The ages of the rocks are shown in the timeline on the left of the poster; on the map, the different letters in brackets show which geological period they are from.
Most of the environments shown on the map are not unique to a particular geological period of time, so letters are used on both the map and the timeline to identify the geological age of the rocks.
You can see straight away that, for example, deserts (coloured orange) occurred across northern and southern Scotland, across much of England, and in southern Ireland.
But these deserts were present at different times in different places because the changing climate has created desert conditions more than once.


Most of the desert rocks from Scotland, Ireland and southern England were laid down under desert conditions during the Devonian Period (around 400 million years ago). However, the desert rocks found across much of the English Midlands were formed when similar hot conditions returned during the Permian and Triassic Periods, some 250 million years ago.
The 'globe maps' show how the position of Britain and Ireland has moved gradually northwards over time. It is important to remember that those deserts would have covered the whole of Britain and Ireland, not just those places coloured orange on the map. The answer is a long history of erosion, burial and plate tectonic forces — as Britain and Ireland have moved northwards across the planet, they have at different times been completely or partially submerged beneath the sea while, at other times, they have been exposed as part of a continental landmass.
Mountain-building episodes raise the land surface, increasing the rate of erosion by wind and water, and tilt the rock strata so that rocks of different ages are exposed in different parts of the country. The poster also contains a long graph that show the global sea-level and temperature through time, relative to their values today. Changing climates also mean that environmental conditions change — as rivers form, change course, and dry up, erosion methods and patterns change, and so different rock types are deposited. New rocks are laid down on top of older ones — if you were to drill a borehole tens of metres into the Earth you would find that the rocks buried deep in the Earth are generally far older than the rocks you see at the surface. This long history of deposition, uplift, and erosion, often repeated in cycles, means the record preserved in the rocks of Britain and Ireland has an intricate three-dimensional structure of which the map shows only the patterns exposed at the surface. Also in the timeline are curves showing the global sea-level and temperature through time, relative to their values today.


From the colour, find out what environmental condition existed at the time the rock beneath your house or school was laid down.
The poster was jointly produced by the BGS, the Geological Survey of Northern Ireland and the Geological Survey of Ireland. The BGS would like to thank the input and feedback we received during production of this poster. You don?t have to wait for someone else to sort it out; rather than worry and feel helpless, you can get up and do something. Each environment is represented by a different colour a€” for example: warm seas are coloured dark green.
This can be seen on the map face by different letters indicating rocks of Devonian (D), Permian (P) or Triassic (T) age.
When dealing with a dynamic planet, things are never straightforward, but this poster gives an insight into the relationship between the rock record, shifting continents and the changing climate.

We would especially like to thank Chris King, Dawn Windley, Pete Loader, Mick de Pomerai, Ruth Richards and Nikki Edwards for their invaluable ideas and constructive comments.
