Climate Stripes for Jersey on display at St Helier's Waterfront

A visual representation of how Jersey’s annual average air temperature has changed since records began in 1894 is now visible on the lower rear wall of Cineworld, adjacent to the underpass.

‘Climate Stripes for Jersey’, a mural painted by local artist Ian Rolls was unveiled on Wednesday 3 June 2020 by Assistant Minister for Environment Gregory Guida. The mural highlights the island is not immune form the effects of global warming and will help raise awareness of Jersey’s climate change.

Deputy Guida said: “The mural reminds us of the impact of climate change on our island and is being unveiled just before World Environment Day. I hope that it will help Islanders to both understand the problem of climate change and think about how we can all help it to be addressed.

During the COVID-19 pandemic, many Islanders have found ways to reduce carbon emissions by walking and cycling more. We should celebrate that fact and march on towards our goal to become carbon neutral by 2030.”

Lee Henry, Managing Director of Jersey Development Company said: “We are delighted to have provided the location and logistical support for the Climate Stripes for Jersey. The stripes exhibit simplicity to Jersey’s metrological records which date back to 1894 and clearly show the Island’s significant temperature rises over the last 126 years.”  

The mural – a graphical interpretation of the rise in temperature was invented by Professor Ed Hawkins, MBE, a climate scientist known for data visualization graphics portraying global warming. The stripes are designed to be used at any location around the world that has more than 100 years of daily temperature records to illustrate the long-term rise in average temperature in a compelling way. Using Hawkins system, the Climate Stripes for Jersey have been created by Jersey Met based on 126 years of historical records collated at the Maison St Louis Observatory.

Each one of the 126 stripes represents one year from 1894 through to 2019 and is coloured and shaded depending on how much cooler or warmer the annual average air temperature was, when compared to the 30 year average air temperature taken from the years 1971 to 2000. (11.785°C).

During the most recent 30-year period, red is the dominant colour, with shading showing the increase in annual average air temperatures in Jersey.

Maison St. Louis Observatory is Jersey’s official climate station and is sited on the outskirts of St Helier. The observatory was founded in 1894 by Jesuit Father Marc Dechevrens and is still the Island’s official recording site for air temperature and rainfall records.
