Yes, the headline is rather self-defeating. I studied persuasion techniques before the Internet got big and one of the trendy manipulation approaches then was to write an article titled "Why XXX" when XXX is some assertion you make, perhaps even with evidence but for which you don't actually offer an explanation (the reader never discovers why XXX, they are only that XXX is true, and why XXX is generally something people would be curious about). This technique naturally has become an arrow in the quiver of click-baiters but with click-bait sooo big now, using such bullshit is more likely to hurt a serious article than help it. The proper title would be "we show human-generated carbon is sufficient to explain climate for the X many years", a significant claim by itself.
