As the world’s leading climate scientists finalize the latest and most comprehensive report on climate change and ways to tackle it, a key question is: What is new? What has changed since the release of the UN climate panel’s last Assessment Report (AR4) in 2007?
On the “solutions” side, the answer is pretty straightforward:
Nuclear power hasn’t changed much. IPCC notes that nuclear capacity is declining globally and that, from safety to financial viability, nuclear power faces many barriers. “Carbon capture and storage” (CCS) isn’t really breaking the mold either. Although the IPCC identifies a need and potential for future CCS-aided emission reductions, in reality, CCS isn’t delivering and, since 2007, “studies have underscored a growing number of practical challenges to commercial investment in CCS.”
The big news is the breakthrough in new renewable energy.
