1. Climate Change -- the scientific debate
Why Hacker News recommends it
HN users point to it as a clear, evidence-based series to counter climate skepticism.
What it is
The first video in potholer54's climate series, giving a basic look at how climate scientists infer that man-made carbon gases are changing the climate. It is a short explainer meant to present the scientific evidence plainly.

It was my mistake to link to the summary, I was actually referring to the full report in the comments before. As for your quote, it needs to be read in the context of the full paragraph. Its written sloppily, but a better phrasing would be: "We don't see the worldwide acceleration observed by Nerem et al. (2018) in the Netherlands' coast area , within the 1993-2017 record". I.e. they are saying the global trend is not the same as the local (Dutch) trend. Perfectly reasonable. > I must say I'm currently on the fence about the role of CO2 in global warming. Well, I could imagine your doubts about sea level rise because they are difficult and uncertain. But there is absolutely no scientific dou

OK, let's watch this. 0:23-ish: No one in the mainstream media in Australia has ever told anyone about Henry fucking Ergas? Well, this is full of shit already. He also ran Concept Economics. > Concept Economics, the consultancy that recently estimated the costs of the National Broadband Network outweighed the benefits by up to $20 billion, has gone into administration. Sheesh, what is it with these climate skeptics and their businesses going under? 0:48: Lack of action across the world? Most expensive carbon tax in the world? Kind sir, I have a graph to cure that ailment: [LINK] Austria is AUT. Australia is AUS, in case there's any confusion following the whiplash you just got by this fact-w

>There's also some evidence that historic rises in CO2 lagged temperature rather than the reverse. That's only true in some cases with strong emphasis on "some". If you want to know how much of that is true and how much is wrong just watch this video [LINK] I don't think I can do it justice with a butchered summary on HN but I'll keep it long enough to get you hooked. There are two phases during a deglaciation and CO2 lags in the first one and leads in the second one. We have basically skipped the first phase by emitting CO2 directly. If anything, this should worry us even more because there is evidence that increased temperatures drive CO2 emissions as well. So we haven't skipped the first
