Even if the Paris agreement is successfully implemented, the planet could still heat up by 5 degrees Celsius, scientists warn. This “hothouse” climate would make parts of the world uninhabitable.
A joint study by international climate scientists from Germany, Sweden, Denmark and Australia presents a bleak prognosis: Even if the goals of the Paris climate agreement are achieved and global warming is limited to maxiumum2 degrees Celsius (3.6 degrees Fahrenheit) compared to pre-industrial levels, the climate system could still passa devastating tipping point.
“Human emissions of greenhouse gas are not the sole determinant of temperature on Earth,”saidWill Steffen, lead author of the study and climate researcher at the Australian National University and the Swedish research institute Stockholm Resilience Centre.
“Our study suggests that human-induced global warming of 2 degrees Celsiusmay trigger other Earth system processes, often called ‘feedbacks,’ that can drive further warming — even if we stop emitting…
