The response to global warming of deep convective clouds is also a substantial source of uncertainty in projections since current models predict different responses of these clouds.

Since most of the measures required to slow the warming, from greatly increasing energy efficiency to land reform in poor nations, would carry other great benefits, and since the probability of unprecedented change appears to be in the vicinity of 50 percent, a very large social effort, one incurring substantial costs, seems to us not simply justified but virtually mandaSince most of the measures required to slow the warming, from greatly increasing energy efficiency to land reform in poor nations, would carry other great benefits, and since the probability of unprecedented change appears to be in the vicinity of 50 percent, a very large social effort, one incurring substantial costs, seems to us not simply justified but virtually mandasince the probability of unprecedented change appears to be in the vicinity of 50 percent, a very large social effort, one incurring substantial costs, seems to us not simply justified but virtually mandatory.

Paul S (# 1)-- Since the Planck Response dominates over positive feedback responses to temperature, wouldn't a La Nina - like failure of surface temperature to rise lead to an increase rather than a reduction in energy accumulation compared with accumulation during a surface warming — presumably a small increase, so that the observed rise in ocean heat content would still be substantial?

As a layman, I can not understand how the «no warming since insert year here» can coexist with the fact that we have just completed the hottest decade on record, containing a substantial number of the hottest years on record.

Meanwhile, more than half of all industrial carbon emissions have occurred since 1988 - and the world remains on a trajectory for substantial and dangerous global warming.

If the recent internal cooling was substantial, this assumption is almost certainly incorrect since energy budget considerations limit the earlier internal warming contribution to no more than 0.1 C and probably less.
