I don't like the way they fudge the graph axes to make it look more dramatic. It's a significant rise all on its own, why make it look suspect by messing with the presentation?

Same with tempestn, 0 isn’t the natural Y-intercept. Just like temperature graphs don’t start at -273°C, nor do barometric pressure graphs start at 0.

I don’t know what the “right” baseline is, but 0 isn’t it.

I don't like sensationalism as it clouds the mind with short-lived buzzes. Instead of always trying to alarm people of the big invisible terror lurking in the dark, we should educate people on how to handle the situation. What are the scenarios? What can we do ourselves for those scenarios (not to prevent, but to prepare)? Which cities and countries will be lost at what point in time? How do we protect ourselves? Be…

Is it sensationalism when it's accurately describing something truly sensational?

We already do this. Go read up on how towns in Florida regularly get flooded by seawater and development continues apace.

I am terrified. Should I be?

I often wonder what we'll die of. Direct consequence of global warming like flooding, tornado, or heat wave? A worldwide epidemic? Will wealth be relevant in saving us from mass famines? A more indirect way such as massive riots caused by, say, the global disorganization of wealth? A global methane event, bursting out of the oceans, and burning the whole atmosphere? Or simply Trump deciding that global warming can only be dodged by erasing half of human activities, killing 4bn people with some atomic bomb, "for the survival of the rest"?

I also wonder what will remain of our cities. Will scavenger humans haunt them for the next thousand years? How fast will they decay?

Earlier quoted context omitted.

No, that would lead to paralysis. Learn to live in a world where climate change is happening and adjust accordingly. There is no way going back now. The party is coming to an end. We must go forward. You don't have to solve this problem in one day by yourself. You probably cannot really "solve" it at all. It's time to let go of things we cannot save and hold on to those which grow valuable in the future.

I really resonate with this comment. The best way to 'deal' with climate change on an individual level is to always vote for folks who are trying to rein it in, to live your life with a minimal carbon footprint, and to create plans for larger, more intense weather events.

Even the high end of predictions aren't expecting an increase in intense weather events bigger than what you might get if you were a bit unlucky over the next century.

Howdy! I work in cleantech, and I guess it's that time again for a what-are-we-going-to-do-about-it post :) To start, here's my favorite climate change joke: "They say we won't act until it's too late... Luckily, it's too late!" ==So what can you do about it?== The biggest thing this article doesn't say that is most relevant to the HN audience is that you can work at a new energy technology company! Our industries ar…

Do you have any recommendations for major metro/tech hubs to avoid settling down (i.e. planning to spend the next 10-20 years) in due to significant threats from climate change? And/or any recommendations for regions in the US that are expected to fare better?

Hi, I don't see anything in your list about carbon sequestration. Can you point me to any companies investing in advanced robotics to assist in silicate mineral crushing & spreading, as it's the only sensible, achievable sequestration technique? Thanks. For readers interested in carbon sequestration, please check out the following paper: "Enhanced chemical weathering as a geoengineering strategy to reduce atmospheric…

Carbon sequestration does not produce immediate benefits, like being a cheap way in making bricks (extreme example).

It is like the insulin injections to a person that got already type-2 diabetes.

I have seen some solar companies in my region, but I honestly am not convinced yet that solar is the way to go. Does anyone know if solar can sustain itself? (Does a photovoltaic panel produce more electric energy during its lifetime than was required to produce it?)

The New York Times published a visualization of estimated number of extreme temperature days over the next 80 years which may be useful for you. https://www.nytimes.com/interactive/2016/08/20/sunday-review...

You can also find maps of areas affected by sea level rise. As you would expect these are mostly low-lying coastal areas. Here's some maps of the effect of a 25 foot rise in sea level on San Francisco: https://urbanlifesigns.blogspot.com/2012/12/the-streets-of-f... (This is beyond most estimates for the 21st century, anyway, but interesting to look at.)
