Chart illustrates global warming from 1880 to today. Will this convince deniers?

Jason Samenow at The Washington Post says, "If you have any doubt the balance of the globe has warmed over the last century, view this chart."

He explains:

From the 1880 to the 1920s, blue and green shades dominate the chart, signaling cooler than normal temperatures in that era. Then, from the 1930s to the 1970s, warmer yellow, oranges, and reds shades ooze in, balancing the cooler shades.

But since the 1970s, the blue and green shades rapidly erode and oranges and reds take over, dramatically.

The rapid warming at the northern high latitudes especially jumps out in recent decades, reflecting “Arctic amplification” or more intense warming in the Arctic. Although the warming is most pronounced up north, it is apparent at almost every latitude.

Samenow concludes that we should show this chart to any climate change deniers, as if it will sway their disbelief in the science of manmade global warming. I don't suppose it hurts to try, but I am doubtful it would make much difference. I think it is safe to say that anyone that still doubts the reality of this crisis is unlikely to be influenced by things like facts, even if they are nicely charted. There is already overwhelming consensus among scientists that global warming is occurring and related to human behavior. And we can see the effects already occurring all around us. I'm not sure what will convince the remaining deniers, but I am skeptical this chart will do the trick.

Do you have a denier in your life? Ask them what piece of evidence they would need to see to change their mind. I'd be curious to hear what they have to say.
