This is a relatively well-researched list: http://www.drawdown.org/solutions-summary-by-rank
I don't really agree with the proposed list. It is listed based on the reduction certain solutions could potentially offer, but the limits of the reductions they offer are not correct. So for example, the impact of cement is way higher but their proposed solution isn't carbon negative or carbon neutral concrete but just a reduction in the carbon footprint. So if they were optimistic about the outcome, the order in th…

I’ve upvoted your comment. It’s flawed logic, but I see it as highly counterproductive to downvote people who seem to be reasoning about a problem or discussing their perceptions in good faith. So many revered scientists have made comments that today would sound jackass silly. I doubt anyone here doesn’t have such comments under their belt. Thinking or asking alone can never be wrong. As long as it’s well intentioned…
I upvoted your comment because we need more people like you who are able to disagree without turning the other person into a villain or idiot just because they disagree. Personally, I have become more skeptical of not climate change or even whether humans have an effect but of whether it's catastrophic and I have shifted my thinking quite a lot to accept that humans will not only have an effect on earths climate, we…
Updated data on the second chart for 2018: http://ocean.dmi.dk/arctic/meant80n.uk.php Such an outlier is not completely unprecedented it looks like from his chart, but only if it immediately and rapidly corrects downwards in the coming days...
Please don't just downplay such an event if you don't know anything about it. This temperature measurement may not be completely unprecedented, but as DMI write about it: Plus degrees are unusual DMI has measurements from Kap Morris Jesup back to 1980, and reveals that in February, above zero degrees are definitely not usual at the world's northernmost land-based measurement station. In fact, DMI has only twice previ…

It sounds like the problem is irresponsible people, not capitalism per se.
Well capitalism is about concentration of wealth in little group of individuals. This little groups holds much power and power corrupts, hence the irresponsible people in position of power is a consequence of capitalism. Of cours this is not the only cause, but this one is significant. From what I gather the underlying issue is one of culture of self and selfishness.

What if scientists regularly engage in falsifying and otherwise manipulating their results to fit their agenda? What if the very statistical methodology they follow is open to abuse? If we are to give wholesale acceptance to anyone who is an 'official scientist,' yet they could well be corrupt, how is that epistemically responsible? Furthermore, why must we blindly accept the status quo when there are legitimate diss…
No need to resort to FUD, the thing you are mentioning happen and we can look at them. One such high profile example is Andrew Wakefield study published in the lancet which is the starting point for the "vaccines cause autism" controversy. What happened is the author got caught, found guilty of professional misconduct and removed from practicing medicine while the paper was retracted. But this had consequences as a g…

For me it is hand wavy doomsday scenarios that makes me skeptical, along with hand wavy predictions that don't come true. My thought is that if it truly was as serious as people say, the evidence and argument would feel a lot more solid and there would be less fearmongering.
I'm not sure what doomsday scenarios and failed predictions you're referring to but even though for some reason it feels otherwise to you evidence and argument is quite solid. Seems you may be victim of a bias of some kind here[1], or have been exposed to some misinformation of some kind. [1]: https://youarenotsosmart.com/2017/01/30/yanss-094-how-motiva...
