While 1.5 degrees isn’t a magical tipping point for Earth’s demise, the United Nations has warned of severe and potentially irreversible consequences above that level.
Hansen and his colleagues analyzed paleoclimate data and the Earth’s energy imbalance to estimate that doubling carbon dioxide could lead to a whopping 4.8 degrees of warming compared with the preindustrial era.
Michael Mann, a professor of earth science at the University of Pennsylvania, posted a lengthy critique of the paper on his personal website.
“While I hold James Hansen to be one of the most (if not the most) important contributors to our modern scientific understanding of human-caused climate change, I feel that this latest contribution from Jim and his co-authors is at best unconvincing,” Mann wrote.
For decades, scientists have avoided providing any policy prescriptions for dealing with the problem of climate change, preferring to stick to science and data.
Hansen and colleagues call for a rising price or tax on carbon emissions, subsidies for renewables and nuclear power, and global cooperation on climate goals.
