You can hover with the mouse over the year labels at the bottom to highlight their curves... go on and do that for each column of years, from top to bottom... that will let you see how the curves rapidly went up for every single column, which is roughly a decade for each row. And it seems to be going up *faster* for the latest decades. This is really scary.
