Explainer: How the rise and fall of CO2 levels influenced the ice ages
WEBJul 2, 2020 · The web page explains how changes in atmospheric CO2 concentrations amplified the effects of orbital cycles on the Earth's climate over the past million years. It shows how CO2 fell as ice sheets grew and warmed as they melted, and how human activity has increased CO2 levels above pre-industrial levels.

WEBSep 28, 2020 · A guest post by two researchers from the University of Exeter argues that the oceans have a larger carbon sink than previously thought. They use satellite data, sea temperature and CO2 solubility to estimate the ocean uptake of CO2 and its implications for the global carbon budget.
Explainer: The high-emissions ‘RCP8.5’ global warming scenario
WEBAug 21, 2019 · RCP8.5 is a climate modelling scenario that assumes very high greenhouse gas emissions and no policy action to limit warming. It is not a likely or preferred outcome, but a worst-case scenario that has been used in some studies to explore climate impacts.
Factcheck: 21 misleading myths about electric vehicles
WEBOct 24, 2023 · Electric vehicles (EVs) significantly cut lifecycle greenhouse gas emissions in almost all circumstances and are the key technology for decarbonising road transport. This web page debunks 21 common misleading claims about EVs, such as their carbon debt, battery lifetime, charging infrastructure and competition with petrol cars.
‘Food miles’ have larger climate impact than thought, study …
WEBJun 20, 2022 · A study finds that global food miles are responsible for 3bn tonnes of CO2e emissions, accounting for nearly one-fifth of total food-system emissions. The study considers the entire food supply chain, including transporting fertilisers, machinery and animal feed, and shows that affluent nations are the main drivers of food miles.
