Can someone help me understand why when there’s a record cold month, there’s a convo like this > non-believer: “see global warming doesn’t exist” > believer: “you can’t measure this on a monthly scale, it’s too slow of a process” But often when the case is reversed, it’s used as evidence of global warming? I know global warming is real and I am a firm believer in it but this duality seems to cause a lot of issues whe…

So… Why is there a climate scientist working for a payments processor?

> Why is there a climate scientist working for a payments processor? Without any explanatory details, this seems like a non-sequitur. Or are you making a joke? Is this like the surrealist painters and bathtub one?

It could be part of a clever marketing strategy. If enough people believe isn something they are likely to pay a premium for services that satisfy their beliefs.

Because the correct answer from the believer is "it's called climate change not global warming and it's expected to cause new extremes in both directions"

1. please a reference to these record cold months and related discussions? curious, iirc see them starting more go the other way round, always. (what I remember, actually when was the last one really? Cause I only remember local record cold ones). 2. it is a trend and usually never one example put up as evidence, but the trend/frequency is unfortunateley clear?

It's generally local events. I remember some time ago when the north pole got so warm that the polar vortex collapsed and ice cold polar weather spread south across the central US, leading to blizzards in Texas.

That may have been record cold in Texas, but it was caused by record heat on the north pole. But people experience local extremes much more than global extremes, which are generally just statistics. And more people live in Texas than on the North Pole.

There's an interesting theory that surface warming of the Earth is proceeding in a staircase fashion, due to modulation of fossil-fuel-forced warming by El Nino events: http://euanmearns.com/the-staircase-hypothesis-an-alternativ... The driving mechanism for this phenomena would be release of stored heat from the oceans (which have been steadily absorbing much of the energy being trapped by increased atmospheric IR-a…

Sadly this assumption does not seem to hold.

One data point doesn't contradict a trend. It doesn't confirm the trend either, but does provide support for it.

Just look at the chart at the top of the article. The world isn't cooling down, and one slightly cooler month isn't any evidence that the trend will reverse itself, it just demonstrates that the trend isn't monotonic.
