Only going back to 1850 is exactly the kind of thing someone would do if they wanted to cherry pick their data to suit a case. You have to go back much further. It is known that at that time we were coming out of a period of much cooler temperatures. See for example the year without a summer (1816). There are periods of human history where it was warmer than it is now. For example, during the Viking expansion, and du…

To be fair, the longer one goes back in time the less data there is and I would hazard a guess that prior to 1600 there is no direct data at all.

We do have history though Check out the Roman Climatic Optimum, for example.

Make sure your assets are shielded from the consequences. I'm a strong believer in voting with legs. For example - it's insane how the Miami real estate prices ignore what's going on (they even have a cheerful name - "sunny day floods"): https://fred.stlouisfed.org/series/MIXRNSA Just sell it already! There's nothing good waiting for Miami, the city will die. Rent if you really want to stay till it blows up. As far a…

Minor correction: hundreds of millions of refugees is the best case scenario in the UN climate refugees projection.

You can go to L'Anse aux Meadows and see the ruins with your own eyes. You can then look around the area and look at the trees.

People on HN hate it when you say we have to change our whole society to deal with this problem. I agree with you though. I don’t think we’re willing to do what is necessary to avoid serious catastrophe. We’ve done a good job demonstrating that for 50+ years so far.

> People on HN hate it when you say we have to change our whole society to deal with this problem. We obviously don't have to change our whole society to deal with that problem. 1) I've been told that renewable are now grid competitive in cost and the power system is switching over to them naturally. 2) At any point we could go nuclear - even the most pessimistic anti-nuclear activist would have to admit that the ris…

You'd be surprised how much anti-nuclear activists would disagree with your second point. I'm sure I know a couple that would rather watch the world burn than vote for someone that will build a single reactor.

I think once an issue like that becomes a left/right black/white thing all logic just goes straight out the window. You can't even say the word nuclear without hearing a cacophony of statements about the price of nuclear vs renewables, as if those claims don't need any actual numbers to go along with them.

Stop buying stuff without thought. I know that a lot of people feel helpless because it's the big corporations that are emitting, but companies only emit CO2 if consumers pay them to do so. Buying everything consciously, whether its food, appliances, housing, or a ticket to some performance, will make the world better.

This is a pretty good idea but it needs a lot of people doing it.

We're in the process of moving home and putting everything into boxes makes one realize how much crap one has bought unnecessarily.

We're on a relatively special case in that we've only recently moved (18 months ago) so we actually have stuff that has never been used in our current house. A lot of this stuff has been donated to charity and some tossed but still my gf wants to take some stuff that hasn't been used in at least 18 months to the new house.

I am excluding Tools and camping gear from the list. The former for obvious reasons, the latter due to having recently had a baby we've not been camping for a bit, YMMV

"The data are a mix of the CRUTEM4 land-surface air temperature dataset and the HadSST3 sea-surface temperature (SST) dataset. The HadCRUT4 data are neither interpolated nor variance adjusted."

This is your typical half-truth (lie of omission). Even if the HadCRUT4 folks themselves don't make these kinds of adjustments, the folks who provide the data sets which HadCRUT4 is based on most certainly do.

See for example the year without a summer (1816).

As far as cherry-picking goes to suit a case, this also sounds like a pristine example. Even worse then what you are countering, since it is only one single year.

There are periods of human history where it was warmer than it is now.

Well, yes, but what does that prove?

The buildings were made with logs from trees that do not exist there today because it is cooler now

You make this sound as evidence of something, but what? That the people shipped trees there from somewhere else? That those trees grew there but now are extinct due to some disease or bug?

Don't get me wrong, I'm open to whatever evidence provided, but if you're going to go against something at least come up with quality arguments. None of what you wrote supports a solid case against the anomalies presented.

What data would convince you that anthropogenic climate change was real?

Just a ground swell at the local level, cities all around the world are calling climate emergencies including all the main cities in New Zealand. The NZ government will have to follow suit. Bigger cities are following too including New York and Sydney today.

But I think that by the time the government start making changes, it will be too late, as it is too late now. Like humanity must have a dramatic change - from top to bottom. The system is against the world We live in a finite world consuming like it is infinite Every action counts, but it will be hard and it must be super reinforced by law

Well, depending on where you are you can also vote for the local green party. If you're in a proportional election system then that the bigger the green voting block is the better. If you're in a country with a first-past-the-post electoral system like the US, UK, or Australia then things are much tougher and you should also be campaigning for electoral reform to make your country more democratic.
