Do bear in mind that most of the costs of global warming are based around:

1) It is happening much faster than we can cope with. If it was happening over 10,000 years then we'd slowly adapt. Or die out. One or the other.

2) Our cities are mostly built on coastlines, and will therefore be hit dramatically by severe weather and by sea rises.

Plenty if you care to look. See https://en.wikipedia.org/wiki/Global_temperature_record for more recent temperature evidence on the scale of a few thousand years, and https://en.wikipedia.org/wiki/Geologic_temperature_record for geologic evidence of temperature patterns over the past half-billion years.

This graph shows just how far off the norm we are for the past two millenia:

Now, it's kind of silly to keep asking HN people to google things for you. But:

100-200 years is pretty fast when compared to how slowly climate moves in one direction or the other. Also those 100-200 years are the same in which human instrialization took place. Measuring temperature in a global scale is a very daunting task and it is open to interpretations by negationists and reactionaries, but you can look for pictures of the last 30 years in the North Pole. The Arctic is going to be open to navigation soon. You can also ask the climate experts, we have to rely on them, and the vast majority of them are predicting a similar effect.

First you yourself start talking about "the last decade", and now one or two centuries isn't long enough.

You also say you think the last decade seemed colder, the reply you got was that 16 of the 17 hottest years since recording began were after 2000. But you ignore that part of the reply.

You are working for the forces that want to stop our mitigation of the problem, you are the enemy.
