The rise in CO2 emissions due to the burning of fossil fuels from 1880 through the 1940's was not sufficient to have played a major role in the considerable global temperature rise that took place during that period — so if we want to presume that sea level rise is prompted by global temperature rise (along with concomitant melting of glaciers, etc.) then we can't really attribute very much of the rise in sea levels during that period to CO2.
I am very skeptical that on a global population level, humans will bother to do anything other than lip service when it comes to addressing climate change and the changes to our lifestyle required to significantly reduce our emissions, until it is far too late.
However, it is important to keep in mind that we might easily more than double it if we really don't make much effort to cut back (I think the current estimated reserves of fossil fuels would increase CO2 by a factor of like 5 or 10, which would mean a warming of roughly 2 - 3 times the climate sensitivity for doubling CO2 [because of the logarithmic dependence of the resulting warming to CO2 levels]-RRB-... and CO2 levels may be able to fall short of doubling if we really make a very strong effort to reduce emissions.

Thus, the concept of an emissions budget is very useful to get the message across that the amount of CO2 that we can still emit in total (not per year) is limited if we want to stabilise global temperature at a given level, so any delay in reducing emissions can be detrimental — especially if we cross tipping points in the climate system, e.g trigger the complete loss of the Greenland Ice Sheet.
What is clear is that uncontrolled emissions will very soon put us in range of temperatures that have been unseen since the Eemian / Stage 5e period (about 120,000 years ago) when temperatures may have been a degree or so warmer than now but where sea level was 4 to 6m higher (see this recent discussion the possible sensitivities of the ice sheets to warming and the large uncertainties involved).

The first is climate inertia — on very many levels, from fossil lock - in emissions (decades), ocean - atmospheric temperature inertia (yet more decades), Earth system temperature inertia (centuries to millennia) to ecological climate impact inertia (impacts becoming worse over time under a constant stress)-- all this to illustrate anthropogenic climate change, although already manifesting itself, is still very much an escalating problem for the future.

One reason for being confident about there being much more uncertaintly than the 97 % concensus suggests is that there is nothing like a concensus, let alone proof, of what caused (and causes) the extreme natural variations in climate throughout geological time.This variation is well documented and almost certainly has a variety of underlying causes which are likely to be very different from C02 or other MM emissions even if higher greenhouse gases levels have often been present.

This is true because most mainstream scientists have concluded that the world must reduce total global emissions by at the very least 60 to 80 percent below existing levels to stabilize GHG atmospheric concentrations at minimally safe atmospheric GHG concentrations and the United States is a huge emitter both in historical terms and in comparison to current emissions levels of other high emitting nations.

Although there is considerable scientific evidence that limiting warming to 1.5 degrees C is necessary to prevent very dangerous warming, a fact implicit in the recent Paris Agreement in which nations agreed to work to keep warming as close as possible from exceeding 1.5 degrees C additional warming, if the international community seeks to limit warming to 2 degrees C it must assure that global emissions do not exceed the number of tons of CO2 emissions that will raise atmospheric concentrations to levels that will cause warming of 2 degrees C.
