Predictions

The predictions used by The Prediction Machine – for a fictional 2045 – have been calculated using a very simple model. The model will be using live temperature from a weather station on the roof garden at FACT, Liverpool (UK), it then adds the projected increase in annual average temperatures for North West England (based on the MET office Ringway weather Station), estimated within a 30 year range from 2040 – 2069.

Modelling Climate Change

Climate Scientists create models to project how the climate might change in the future, based on what they see happening to the climate now and in the past.

The calculations for the predictions made by The Prediction Machine are for a future dominated by consumerism and globalisation – that the scientists call a high emissions scenario – where C02 continues to increase in the atmosphere due to our ongoing use of fossil fuels (oil, coal, gas etc…). In this case the temperature is projected to increase approximately 3.7 degrees centigrade over the period of 2040 – 2069. Future versions of the machine will use a more complicated climate model, in order to represent a more complex picture of how the climate might change in 30 – 50 years time.

Please note that The Prediction Machine has been informed by scientific climate and weather data but interprets this data through dialogues with communities and scientists in order to give us a sense of how today’s weather might feel in the future, it does not aim to create a scientific climate model.  The predictions have been written with people who live and work in Nottingham and Loughborough (UK) and Rio State (Brazil) representing their own interpretations in response to climate data, written during workshops with the artist and as part of an artist residency in Brazil. The Prediction Machine therefore enables us to reflect on how we perceive climate change in our everyday lives – rather than as a scientific model.

What Is Climate Change?

The Prediction Machine focuses on human made climate change.

Climate Change is most commonly talked about in relation to human made (anthropogenic) changes in the earth’s climate (Norgaard 2011; Washington 2013; Wrigley 1999; O’Hare et al. 2005).  

The anthropologist Norgaard suggests that there are two basic facts that we need to be aware of in order to understand issues of anthropogenic (human induced) climate change:
‘if global warming occurs it will be the result primarily of an increase in the concentration of carbon dioxide in the earth’s atmosphere… the single most important source of carbon dioxide is combustion of fossil fuels’ (Norgaard 2011)

There are differences between the terms ‘climate change’ and ‘global warming’. Climate change relates to a broad definition of the Earth’s climate, whereas ‘global warming’  focuses on the Earth’s ‘increase of temperature over time’ (Boykoff 2011). Global warming can be seen as the ‘fingerprint’ for human made climate change (Wrigley et al. 1999).

Ongoing social, economic and political discussions focus on whether and how we can put less CO2 (Carbon Dioxide) into the atmosphere (mitigation) and/or deal with the consequences of our use of fossil fuels (adaptation).

Weather and Climate

Climate is different from weather. Climate is the patterns and trends of weather in the Earth’s atmosphere that are measured over a particular region, or globally, over a long period of time (typically 30 years). Weather is what is happening in a particular place, at one moment and over a shorter period.

The Prediction Machine plays with our ideas of climate and weather, it uses climate data (a projection of long term temperature trends for a 30 year period) to give an impression of what the weather and our world might be like in the future, as a result of the climate changes projected by scientists.  This is a common if not over simplistic way to model how climate change might affect us in the future and has been developed in dialogue with several climate scientists who have advised the artist throughout the development of the project.
