"CO2 after the turn of the century continued to increase. In fact, if anything slightly faster. Global temperature didn't. If anything, it decreased in the first decade of the 21st century."
"Future atmospheric CO2 is only marginably predicable and in significant part, not controllable. That means the changes in human emissions will not be tracked by changes in atmospheric CO2. They never have been."
"The popularised view has been that CO2 is driving the bus and climate is along for the ride. The observed behaviour reveals just the reverse. Climate is at the wheel and to a significant degree, CO2 is at the back of the bus."
