To put things in perspective

We've already warmed up the planet by about 1C from pre-industrial times, and...well, pretty much nothing consequential happened

Based on the most likely temperature impacts of the most realistic emission scenarios, we're looking at an additional 0.8C (optimistic) to 1.5C (pessimistic) on top of that by the end of the century, with the temperatures plateauing shortly afterwards. No, Earth will not become the next Venus, nor will Greenland and Antarctic melt (it's -30C there right now)
