You may want to look up Pollyanna. You seem to be confused as to the meaning. While you're at it, you may want to look up the economic cost of the projected sea level rise for Miami alone. If you're going to have a strong opinion on this topic it may as well be an informed one.

During the Pliocene three million years ago, the climate was 2 to 3C warmer and the seas were 25–35 meters higher than today (Dowsett et al., 1994; Rahmstorf, 2007). I'm sure the critters of the time loved it, but our coastal cities would not. The last 10,000 years is of interest because that represents the birth of our civilization. It is the climate that we have adapted our infrastructure to.

So if the IPCC says warming is slower (over the last decade), how do you extrapolate a greater increase of temperatures over the coming years

What we have is annual and decadal variability superimposed on a secular anthropogenic warming trend. If you look at a very short interval, you will see primarily the variability. If you look at a longer interval, you will get a clearer picture of the secular anthropogenic trend. Neil deGrasse Tyson has a good illustration here: https://www.youtube.com/watch?...

Here is a 10,000 year view of global mean surface temperature: http://cdn.zmescience.com/wp-c...

There was a slow cooling for about 6000 years, followed by an abrupt change in trajectory over the last century. The warming over the last century has been attributed to fossil fuel emissions.

Layzej writes: Based on data from January to September, the HadCRUT dataset shows 2015 global mean temperature at 1.02 C (±0.11 C) above pre-industrial levels for the first time. The Copenhagen Accord recognizes "the scientific view that the increase in global temperature should be below 2 degrees Celsius." Physics Ken Rice points out that the next degree Celsius may be closer than we think. "It’s taken us about 160 years to warm by about 1C. This is associated with emissions of about 550GtC (550 billion tonnes of carbon, or ~2000 billion tonnes of CO2). Current emissions are around 10GtC/year. If we continue emitting as we are, we will double our cumulative emissions in about 50 years. If we continue to increase our emissions, it will be even sooner.
