Zara Qadir, Communications Manager at the Sustainable Gas Institute, discusses why climate scientists need to step onto their soapboxes – and how to go about it.
In this opinion piece, Luke Bevan discusses the modern ethical challenges of communicating climate change science to the general public.
Professor Colin Prentice, AXA Chair in Biosphere and Climate Impacts “Carbon Dioxide: The Good News” – This is the title of a recent Global Warming Policy Foundation report (Goklany, 2015) that focuses on the benefits of CO2 for people. In a hard-hitting foreword, eminent physicist Freeman Dyson claims that the entire scientific and policy establishment has been suffering from a form of “tribal group-think” that involves … Continue reading Carbon dioxide: the good and the bad, the right and the wrong
Grantham intern Peter Davies (Department of Physics) delves into global temperature records. Statements such as “2014 earth’s warmest year on record” or “No global warming for 18 years 1 month” are conclusions from different atmospheric temperature data sets. Before assessing which is true it is important to understand how temperatures are measured, how data sets are created and used to calculate global temperatures, and the … Continue reading Taking the planet’s temperature: How are global temperatures calculated?
Grantham Institute Co-Director Professor Joanna Haigh discusses a recent paper which argues that existing climate models ‘run hot’ and overstate the extent of manmade climate change. It is perplexing that some climate change sceptics, who expend much energy in decrying global circulation (computer) models of the climate, on the basis that they cannot properly represent the entire complexities of the climate system and/or that they contain too many approximations, … Continue reading With climate models, simpler isn’t necessarily better
By Professor Colin Prentice, AXA Chair in Biosphere and Climate Impacts Further to previous posts on this blog regarding Owen Paterson’s recent speech to the Global Warming Policy Foundation, I would like to take this opportunity to correct his dismissive statement about biomass energy as a potential contribution to decarbonized energy production in the UK. This is what the former Environment Secretary said: “Biomass is not zero carbon. It … Continue reading In defence of biomass energy
By Dr Flora Whitmarsh, Grantham Institute In a lecture to the Global Warming Policy Foundation, the former UK Environment Secretary Owen Paterson has criticised the current government’s climate and energy policies, suggesting there is too much emphasis on renewables and that the consequences of climate change have been exaggerated. A discussion of Mr Paterson’s comments on UK energy policy appears in another Grantham blog by Dr Simon … Continue reading Has climate change been exaggerated? Fact-checking Owen Paterson’s comments
By Dr Simon Buckle, Grantham Institute Owen Paterson’s remarks on the UK response to climate change miss the point. I do not disagree with him that the UK decarbonisation strategy should be improved. In particular, there is a need for a more effective strategy on energy demand. However, my preferred policy and technology mix would be very different to his and include the acceleration and expansion … Continue reading Paterson misses the point
By Dr Flora Whitmarsh, Grantham Institute The recent slowdown in global temperature rise has led to suggestions that global warming has stopped. In fact, the Earth system is still gaining heat, and the slowdown was likely caused by a series of small volcanic eruptions, a downward trend in the solar cycle, and increased heat uptake of the ocean. Writing in the Telegraph, Christopher Booker claims … Continue reading Ocean heat uptake – checking the facts
A recent paper on ocean warming has been reported on in a number of newspaper articles, most recently by Christopher Booker in the Sunday Telegraph. The author of the paper, Professor Carl Wunsch of MIT, wrote a letter to the editor of the Sunday Telegraph in response to Christopher Booker’s article. As the letter has yet to be published in the Sunday Telegraph, with the permission … Continue reading Ocean warming in the media
