Climate change and global warming talk
David has lectured at university and been a speaker on climate change and global warming for many years, as well as visiting Antarctica with leading researchers in climate science and working on an international ocean and climate research ship. This talk is great for a school or general audience which wants to know what the impacts might be, the difficulties of measuring environmental change, and how the evidence was collected. As a speaker renowned for his ability to popularise and engage, this talk is far from being dry.
The understanding of climate change, and the role humanity plays, has been a painstaking story of patient detection. Climate changes naturally for a variety of reasons and science has to carefully attempt to seperate the consequences of natural change from anthropogenically caused change. This has involved the development of novel ways of gathering data from the past to better understand the future: from ice cores in Antarctica to the examination of the middle ear bones of dead fish.
