Cover Story: One of the major challenges confronting the Earth is the significant imbalance between manmade carbon emissions and the natural processes of carbon sequestration via photosynthesis. The resulting build up of greenhouse gases such as CO2 and methane that has accelerated since the 1950s is the major driver of global climate change. There is strong evidence that this is already perturbing the previously stable Holocene climate, threatening future food production and social stability. This review analyses the status of the global carbon cycle since the formation of the Earth about 4.54 billion years ago, with a particular focus on the role of biological carbon sequestration in modulating atmospheric CO2 levels. To address the current climate crisis, measures to promote CO2 sequestration, such as the use of high-yield tropical crops and no deforestation, are recommended. View this paper
