"So what does it say? Our regular readers will hardly be surprised by the key findings from physical climate science, most of which we have already discussed here. Some aspects of climate change are progressing faster than was expected a few years ago - such as rising sea levels, the increase of heat stored in the ocean and the shrinking Arctic sea ice. "The updated estimates of the future global mean sea level rise are about double the IPCC projections from 2007โณ, says the new report. And it points out that any warming caused will be virtually irreversible for at least a thousand years - because of the long residence time of CO2 in the atmosphere."First, what is "physical climate science"? How is this different from "climate science". In the past, this terminology has been used when authors ignore the biological components of the climate system.
