unusual in attribution science, which seeks to look for the causes, whether climate change or natural fluctuations, that change the odds of extreme

Reasoning that, because it fluctuated daily, water vapour was continually recycling itself in and out of the atmosphere, he turned his attention to carbon dioxide, a gas resident for a long time in the atmosphere whose concentration was only (at that time) dramatically changed by major sources such as volcanoes or major drawdowns such as
unusual and massive episodes of mineral
weathering or the evolution of photosynthetic plants:
events that occur on very long, geological timescales.

Imagine, say, a bell - shaped curve based on the null hypothesis that climate change is not happening (and not having an impact on increasing extreme
weather events), and there is this really long tail out to infinity; and supposing we get an off - the - charts category 7 hurricane in January, we still can not attribute it or its extra intensity or
unusual seasonality to climate change, even if there is only a one in kazillion chance it might occur without climate change having an effect — that is, it is way out there in the very tiny tail of this null hypothesis curve that fades out into infinity — the tail that says, afterall, anything's possible.
What I do see, however, is a coming era where every single

One political implication of this normalization process is that if global warming proceeds slowly enough, then the potential exists that we will just progressively become more used to

events.
