The error bars are not large enough to be seriously confident that the problem can be ignored, though. Basically everything we have says that: * Humans are causing basically all of the warming happening, either directly or indirectly * All of that warming will eventually be enough to kill most or all of us within 40-100 years, especially if nothing is done, but even still eventually if we stick to current commitments. There's literally no reason to faff about anymore - we have direct, quantifiable evidence that people are being killed and displaced by climate change related events today, and it will only get worse as time goes on. Hurricanes are stronger, wild fires are wilder, sea levels are rising and driving people off of low lying islands, glaciers are melting, the northwest passage has stayed opened for literally the first time in living memory, coral reefs are overheating to death, species are migrating north or just straight up going extinct. This is a problem now and immediately that the human race needs to address in force.
