The LIP is known as the North Atlantic Igneous Province or NAIP and is one of the largest LIPs on Earth.

Dr Stephen Jones who was involved in the study said: “Large Igneous Provinces are linked to spikes of change in global climate, ecosystems and the carbon cycle throughout Mesozoic time – coinciding with the Earth’s most devastating mass extinctions and oceans becoming strongly depleted of oxygen.

“We calculated carbon-based greenhouse gas fluxes associated with the NAIP – linking measurements of the process that generated magma with observations of the individual geological structures that controlled gas emissions.

“These calculations suggest the NAIP caused the largest transient global warming of the past 65 million years.
