Climate Scientist Fears His "Wedges" Made It Seem Too Easy
The co-creator of the widely cited "wedges" approach to a climate change solution now thinks he made the job seem too easy.
When the torrent of predictions about global warming got too depressing, there were Robert Socolow's "wedges."
The Princeton physics and engineering professor, along with his colleague, ecologist Stephen Pacala, countered the gloom and doom of climate change with a theory that offered hope. If we adopted a series of environmental steps, each taking a chunk out of the anticipated growth in greenhouse gases, we could flatline our emissions, he said. That would at least limit the global temperature rise, he said in a 2004 paper in the journal Science.

The Princeton colleagues even created a game out of it: choose your own strategies, saving a billion tons of emissions each, to compile at least seven
