Greater electricity, nuclear and renewable energy will be the most cost-effective method of reducing carbon dioxide emissions by 2100, researchers at PNNL have found.

Computer modeling compiled by researchers from the Joint Global Change Assessment Model generated a scenario that will be used to understand what effect different greenhouse gases could have on the climate.

“Without any action, the emissions, and the heat trapped in the atmosphere, would be much higher, leading to more severe climate change,“ said lead author Allison Thomson

The computer modeling developed one of four different scenarios that will be used to study the effects of greenhouse gases on the climate and how to minimise the impact.
