Un articolo su Eos, rivista della Società Americana di Geofisica, riassume un recente articolo scientifico che indaga sulle cause delle discrepanze nelle emissioni di CO2 fra lo scenario business-as-usual dell’IPCC e il mondo reale:

The most extreme model, RCP 8.5—sometimes called the business-as-usual scenario—describes rampant burning of fossil fuels, a global average temperature increase of nearly 5°C, and mean sea levels roughly a meter higher than they are today. But climate and energy experts disagree over how likely it is that this high-emissions scenario will come to pass. A recent study published in Environmental Research Letters found that the emissions trajectories in climate assessments from the IPCC overshot actual energy emissions over the past 15 years.
