Professor Happer is a World Authority on Climate Change from Princeton University, USA. This is a unique opportunity to hear the latest science surrounding this subject. The Methane Science Accord and Groundswell are honoured to host Dr William (Will) Happer, emeritus Princeton physicist and global authority on radiative transfer, greenhouse gases, and climate sensitivity. This tour offers New Zealand farmers, growers, scientists, business leaders, and policymakers a rare chance to hear from a scientist with more than 60 years of groundbreaking research behind him. Dr Happer is known worldwide for cutting through political noise and presenting science grounded in data. His work with Dr William van Wijngaarden is strongly supported by satellite measurements and is reshaping global conversations about methane and climate policy. What Dr Happer will cover
• How greenhouse gases actually influence temperatures
• Why current methane policies may be scientifically flawed
• What this means for the future of New Zealand’s pastoral sector Links Link to entire presentation including all questions and answers.
