RHS Director of Science Professor Alistair Griffiths comments on the IPCC Climate Change 2021 report

“Today’s IPCC report is a sobering reminder of the impact of climate change and the part we all have to play in reducing emissions and protecting our planet for the future."

“With an estimated 30 million gardeners in the UK our gardens, plots and even pots can make a difference through delivering services previously provided by the natural environment; such as reducing water run-off and minimising flooding, drawing and storing carbon from the atmosphere and helping to shade and cool urban areas. By adopting greener gardening practices we can all contribute towards stemming the tide of climate change and be better placed to weather extreme climate events.”
In 2017 the RHS published Gardening in a Changing Climate which highlights the importance of gardens in terms of their interaction with the natural environment and provides recommendations on how gardeners can adapt to climate change through plant choice and garden design. RHS Hilltop: the home of gardening science at RHS Garden Wisley also introduces visitors to the findings within the report and provides a home for the charity’s 100-strong team of scientists.
