There is a high probability that the anthropogenic increase in the global mean surface temperature anomaly is about 1C. That is a large number over a short time scale. The current CO2 concentration is about 420 ppm and that may grow to 600 ppm by the end of the century. CO2 impacts the long wave radiation budget of the atmosphere and causes stratospheric cooling and lower tropospheric warming. There can also be positive feedbacks to further the warming. There is a high probability that it will increase to 2-3C by the end of the century. Remember, while we are in an interglacial period, the time scale of concern is about 200 years and this is well below the time scale of the natural climate forcing from the Milankovitch cycles. Unfortunately, that will cause issues in coastal regions, along with subsidence of some coastal plains. Some geopolitical unrest is likely as some areas of the world are negatively impacted more than others. And, contrary to what some people are fond of suggesting, the world will not be ending as we will do what humans have always done; adapt. If you are looking for references, AR6 is a good place to start.
