Global warming is a lie

I like your use of the double negative on the Y-axis, as it makes the visualization very misleading. I agree with your conclusion that your product turned out really well, and the only thing I might consider changing would be the gradient. It seems that you have a gradient on the entire graph, not just the line, from top to bottom, but the gradient on the line goes from left to right. I think you could make the gradient on the line also top to bottom, though I'm not sure how you added the gradient, and the orientation of the line will still make it a left to right gradient. The only difference is in the small valleys and peaks in the graph, the color would better represent the temperature, that is, the valley would be bluer than both of the mountain peaks next to it.
