Can numbers, algebra and trigonometry save the planet? This was the question put to experts during a panel discussion at Imperial hosted by the Grantham Institute and the Mathematics of Planet Earth CDT. CDT students Paula Rowińska and Tom Bendall report back on seven ways that mathematicians are already working towards securing our planet’s future. From meteorology to economics, a wealth of scientific research … Continue reading Seven ways maths can save the world
On 22 April, over 170 nations signed the global climate agreement drawn up in Paris in December. As we reach a turning point in global action on climate, Grantham Institute Head of Policy and Translation Alyssa Gilbert discusses the next big questions for climate research. The climate change deal forged in Paris was a triumph of science, as well as politics. But the agreement was … Continue reading Climate science: what’s the next big thing?
Dr Jan Zika, NERC Independent Research Fellow in the Department of Physics and a Grantham Affiliate explains why we need brilliant climate scientists now more than ever before. In 1560, our moon did something that it does only every generation or so. As it circled the Earth at a stately pace of one rotation per 27 days, it found itself directly between us and the Sun. … Continue reading Why climate science needs more lunatics
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?
Following recent research suggesting that 90% of seabirds have eaten plastic, Department of Physics undergraduate Peter Sherman investigates how we could clean up our oceans. There is a lot of plastic in the ocean, and the situation is only getting worse. Within the next decade, oceanographers predict that there will be ten times more plastic debris in the ocean than today. Marine plastic is known to have … Continue reading Where can we best tackle the ocean plastics problem?
In the fourth post in our sustainability series, SSCP-DTP student Rebecca Thomas considers the role of the biosphere as a carbon sink, and assesses whether planting trees can really offset carbon emissions. The terrestrial biosphere (land based vegetation) is often considered to have benefited from climate change over the last 50 years (an argument that is used by a number of climate skeptics). Trees, after … Continue reading How much CO2 can trees take up?
by Professor Martin Siegert, Co-director, Grantham Institute See a headline on TV about climate change and it will undoubtedly be accompanied by, among other images, a glacier suddenly calving a colossal iceberg into the sea, or a polar bear clinging helplessly to an ever-diminishing ice floe. Glaciology, the study of snow and ice in all its forms, gets into every living room, hammering in the … Continue reading Why should we act on climate change? A glaciologist’s perspective
This blog post is part of a series on Responding to Environmental Change event, organised by the Natural Environment Research Council (NERC) funded Doctoral Training Partnerships at Imperial (SSCP), and the University of Reading and the University of Surrey (SCENARIO). A recent event in London brought together emerging environmental scientists (PhD students and early career researchers) with leaders from business, policy and academia to explore the … Continue reading Responding to environmental change
This blog post by Malcom Graham, an SSCP DTP student, is part of a series on Responding to Environmental Change, an event organised by the Natural Environment Research Council (NERC) funded Doctoral Training Partnerships at Imperial (SSCP), and the University of Reading and the University of Surrey (SCENARIO). See the full list of blogs in this series here. Environmental hazards are becoming more frequent and severe, … Continue reading Resilience to environmental hazards
