In time, global greenhouse gas emissions will be slowed and stabilized, forcing the CO2 curve to bend downward to acceptable permanent levels, simply because there is no other choice.

We collectively need to demand that there is no acceptable response to climate change other than strong emission reductions, ensuring that atmospheric concentrations of CO2 are returned to 350ppm levels, global temperature rise is kept (at the maximum) 2 °C and, even better, 1.5 °C — to do that, as was emphasized on numerous occasions, we need a F.A.B. climate deal: Fair, Ambitious, and (perhaps most importantly) Binding.

Is there any evidence that worldwide fossil fuel emissions would have been high enough at that early date to already be affecting sea level?

There's a vital difference between reducing the level of greenhouse gases in the atmosphere and reducing current «business - as - usual» emissions.

In general, so long as there is some solar heating beneath some level, there must be a net LW + convective heat flux upward at that level to balance it in equilibrium; convection tends to require some nonzero temperature decline with height, and a net upward LW flux requires either that the temperature declines with height on the scale of photon paths (from emission to absorption), or else requires at least a partial «veiw» of space, which can be blocked by increasing optical thickness above that level.
