Mon 4th September – Dr. David Armstrong McKay, Climate Tipping Points: The Point of No Return?
Man-made emissions have been pushing up Earth’s temperature through the Greenhouse Effect, and much more warming is expected during our lifetimes if emissions aren’t reduced. But warming may not be gradual – passing a ‘tipping point’ can cause sudden change. Scientists are now worried that we’re approaching some of these tipping points, beyond which rapid and difficult-to-reverse climate changes may occur. This helps to make climate change more of a so-called “Wicked Problem” to respond to, as it makes future climate change more difficult to predict and comprehend. In this month’s Winchester Science Café join Dr. David Armstrong McKay to find out about what climate tipping points are, how might they affect us, and whether we can predict and avoid them.
Dr. David Armstrong McKay is currently a Research Fellow in the Geography and Environment department of the University of Southampton studying early warning signals of tipping points in lake ecosystems. He completed his PhD at the National Oceanography Centre, Southampton in 2015 with a thesis investigating perturbations and tipping points in the carbon-climate system over the last 66 million years, and launched the Climate Tipping Points (www.climatetippingpoints.info) ReCoVER Network-funded outreach project in Autumn 2016. He is fascinated by the co-evolution of the Earth, life, and human societies as complex and dynamic systems Earth, and his research focuses on using numerical modelling and analysis to investigate the resilience of the Earth System.
Mon 2nd October 2017 – Prof Roy Weller – Vascular Factors in Dementia
Age is a major risk factor for dementia. This talk will review the effects of age upon the brain and upon arteries that supply the brain. How age-related changes in arteries in the brain may act as a trigger for Alzheimer’s disease and vascular dementia will be discussed as will the possible strategies that could be developed to mitigate the effects of ageing blood vessels on the brain in the management of dementia.
Roy Weller is Emeritus Professor of Neuropathology in the Faculty of Medicine, University of Southampton. For many years he was responsible for the diagnosis of tumours and other diseases of the brain including dementias. In addition to teaching activities he organised an active research programme latterly concentrating on the vascular causes of dementia. Using observations from the pathological study of human brains, he established experimental models to test hypotheses relating to the causes of human dementia, especially Alzheimer’s disease. He is still active in the research field in association with an expanding team investigating vascular factors in dementia and the development of possible therapies for dementia.
Mon 6th November 2017 – Prof Robert Read – Deliberate Experimental Infection of Humans for Medical Discovery
Mon 4th December 2017 – Dr Matt Loxham – Particulates and Health
Mon 15th January 2018 – Prof Tim Underwood – Research into Oesophageal Cancer
Mon 5th February 2018 – Dr. Rick Stafford, Bournemouth University – “The ecology of marine fisheries and its role in a changing political landscape”
Fish are a vital part of the marine ecosystem, and understanding their ecology should play a vital role in managing the marine environment, and especially the fishing industry. This talk will examine the basics of fisheries science, but also explore new research which suggests that overexploiting fish stocks can have unforeseen consequences, such as directly contributing to climate change. It will also examine the relationship between fisheries science, ecology and politics, and explore whether political changes such as Brexit may help or hinder the recovery of UK fish stocks.
Dr Rick Stafford is a Principal Academic in Marine Conservation at Bournemouth University, working both in the natural and social science aspects of conservation. His interests are in the effective protection of biodiversity, biomass and ecosystem function in the marine environment, and has conducted work on the wider ecological issues of fishing, and the effectiveness of solutions such as marine protected areas worldwide.
