For example, evidence was growing that the planet’s oceans — an important “sink” — were increasingly saturated and couldn’t absorb as much as previously of the main greenhouse gas carbon dioxide (CO2), he said.

“Emissions are growing much faster than we’d thought, the absorptive capacity of the planet is less than we’d thought, the risks of greenhouse gases are potentially bigger than more cautious estimates, and the speed of climate change seems to be faster,” he told Reuters at a conference in London.
