The author, Emeritus Professor Richard Selley from Imperial College London, claims that if average summer temperatures in the UK continue to rise as predicted, the Thames Valley, parts of Hampshire and the Severn valley, which currently contain many vineyards, will be too hot to support wine production within the next 75 years.
Instead, Professor Selley says, this land could be suitable for growing raisins, currents and sultanas, currently only cultivated in hot climates such as North Africa and the Middle East.
In addition, he adds that if the climate changes in line with predictions by the Met Office’s Hadley Centre, by 2080 vast areas of the UK including Yorkshire and Lancashire will be able to grow vines for wines like Merlot and Cabernet Sauvignon which are currently only cultivated in warmer climates like the south of France and Chile.
Different grape varieties flourish in different temperatures, and are grouped into cool, intermediate, warm and hot grape groups. For the last 100 years ‘cool’ Germanic grape varieties have been planted in British vineyards to produce wines like Reisling. In the last 20 years some ‘intermediate’ French grape varieties have been successfully planted in southeast England, producing internationally prize-winning sparkling white wines made from Pinot Noir, Pinot Meunier and Chardonnay.
Combining temperature predictions from the IPCC and the Met Office’s Hadley Centre with his own research on UK vineyards throughout history, Professor Selley predicts that these cool and intermediate grape varieties will be confined to the far north of England, Scotland and Wales by 2080, with ‘warm’ and ‘hot’ varieties seen throughout the midlands and south of England.
Explaining the significance of his new study, Emeritus Professor Selley from Imperial’s Department of Earth Science and Engineering, said: “My previous research has shown how the northernmost limit of UK wine-production has advanced and retreated up and down the country in direct relation to climatic changes since Roman times.
“Now, with models suggesting the average annual summer temperature in the south of England could increase by up to five degrees centigrade by 2080, I have been able to map how British viticulture could change beyond recognition in the coming years. Grapes that currently thrive in the south east of England could become limited to the cooler slopes of Snowdonia and the Peak District.”
Professor Sir Brian Hoskins, Director of the Grantham Institute for Climate Change at Imperial College London, said: “This research shows how the environment in the UK could be affected by climate change in a relatively short period of time. Increases in temperature over the course of this century could have a dramatic effect on what can be grown here, including vines.”
Professor Selley’s book is called ‘The Winelands of Britain: past, present and prospective.’ It is the second edition of a work first published in 2004. The new edition includes additional material on the future of UK viticulture, in light of recent climate change models.
Professor Selley is presenting his new work at a special lecture at Denbies Vineyard in Dorking, Surrey, at 2.00pm on Monday 26 May 2008. For a complimentary ticket to the lecture please contact Jeanette Simpson email@example.com

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
