Too late to stop global warming by cutting emissions, say experts

London, October 18 (ANI): Governments and institutions should focus on developing adaption policies to address and mitigate against the negative impact of global warming rather than putting emphasis on carbon trading and capping greenhouse-gas emissions, researchers say.

“At present, governments’ attempts to limit greenhouse-gas emissions through carbon cap-and-trade schemes and to promote renewable and sustainable energy sources are probably too late to arrest the inevitable trend of global warming,” Johannesburg-based Wits University geoscientist Dr Jasper Knight and Dr Stephan Harrison from the University of Exeter in the United Kingdom wrote.

The paper argues that much less attention is paid by policymakers to monitor, model and manage the impacts of climate change on the dynamics of Earth surface systems, including glaciers, rivers, mountains and coasts.

“This is a critical omission, as Earth surface systems provide water and soil resources, sustain ecosystem services and strongly influence biogeochemical climate feedbacks in ways that are as yet uncertain,” they wrote.

Knight and Harrison want governments to focus more on adaption policies because future impacts of global warming on land-surface stability and the sediment fluxes associated with soil erosion, river down-cutting and coastal erosion are relevant to sustainability, biodiversity and food security.
