Why can't people just make honest graphs? If you're trying to convince a skeptical person, the last thing you should do is use known dirty tricks for deceiving them. CO2 and arctic sea ice graphs' vertical axes don't start at zero, making the change look worse than it really is and meaningless without something to compare PPM or km^2 to. Other graphs use a sensible difference for the axis because there's no meaningful absolute zero. It would be nice if they aligned the time axes on all of them for extra readability. The different start dates are a red flag because they might be cherry picking the start date to avoid something embarrassing before that. I guess they just used easily available data which is fine if they don't have the resources to do it more thoroughly, and they explain that for sea level. But it would be more transparent to show a longer history with clear explanation of how start dates were chosen. Actually, sea level really needs a longer history because it has been rising since the ice age and it's important to separate that natural increase from the anthropogenic one.
