you can't run a true experiment because you can't randomly assign "treatment conditions" therefore you can never assume that correlation = causation. Doing so would be irrational in any scientific field. there is a possible association but there is no evidence that suggests that human activity is the cause and we will never be able to prove it.

2019-02-20 23:01:51 UTC  

association and correlation are two completely different things

2019-02-20 23:20:49 UTC  

The Poles are melting

2019-02-20 23:21:39 UTC  

Also, the correlation has happened over millions of years, if a correlation happens for that long, it's probably a causation

2019-02-20 23:24:56 UTC  

It’s not called global warming, it’s called climate change. You must’ve forgot to update your agenda

2019-02-20 23:25:20 UTC  

The words are interchangeable

2019-02-20 23:26:21 UTC  

What about the medieval warm period?

2019-02-20 23:27:55 UTC  

Yeah America is colder, but this is about **Global** warming.

2019-02-20 23:27:58 UTC  

But it’s “warming”

2019-02-20 23:28:07 UTC  

That’s like saying a cold day in summer proves it’s actually winter

2019-02-20 23:28:35 UTC  

There’s always gonna be warm and cold days. You have to look at the overall trend

2019-02-20 23:28:54 UTC  

The world as a whole is warmer, however that means America is temporarily colder due to some weather effect.

2019-02-20 23:29:30 UTC  

This happens periodically. It happens every 1000 years or so infact.

2019-02-20 23:30:48 UTC  

Of course about 12000 years ago we came out of the ice age, so I mean since then.

A bit crude I know, but observe the bumps, they are "warm" periods.

2019-02-20 23:34:11 UTC  

Bear in mind there is a lot of regional variation, for example, Greenland, it actually used to be a lot warmer.

2019-02-20 23:34:57 UTC  

That is to say most the last 10,000 years in Greenland were significantly warmer than it is now.

2019-02-20 23:36:10 UTC  

The if we go way back, we see that this whole global warming thing could just be a blip anyway before we go back into another ice age.

2019-02-20 23:36:23 UTC  

That'd be neat

2019-02-20 23:37:06 UTC  

The ice age was kinda cold, I think most of Europe and America were permafrost or tundra, with glacial features.

2019-02-20 23:37:15 UTC  

I’m not sure if that’s an argument to ignore climate change

2019-02-20 23:37:34 UTC  

Support global warming, avoid the ice age?

2019-02-20 23:37:35 UTC  

what? That the earth has done this plenty of time without humans and it always recovers?

Basically the Earth has a cycle where we will freeze again whatever we do, the entire global warming since the 1600s is barely 10% of the change caused by an ice age.

2019-02-20 23:40:08 UTC  

too bad there's like no sources in any of these graphs

2019-02-20 23:41:26 UTC  

Most of the mid-term ones are based on ice core data, the longer term ones are based on rock data, and the modern ones on recorded observations.

2019-02-20 23:41:36 UTC  

This is a fun one.

It shows how the cycle has got more extreme, and the earth has got colder, over the last 5 million years.

2019-02-20 23:42:50 UTC  

But this doesn't show how humans are not aiding it

2019-02-20 23:43:47 UTC  

I think my point is that humans should do more because otherwise the ice age will still stuff everyone.

2019-02-20 23:44:42 UTC  

All the global warming we have managed so far is about +2 degrees, but an ice age drops us by around -8 degrees, up to -10 max.

2019-02-20 23:45:28 UTC  

My easy bake will keep me warm through the ice age <:PepeIcecreamSundae:475769244680847365>

2019-02-20 23:45:29 UTC  

Therefore, global warming should be continued for at least 400 years more to counterbalance the ice age and keep the world warm.

freshavocado brilliant young man

2019-02-20 23:45:46 UTC  

climate change is indeed real

2019-02-20 23:45:54 UTC  

but it's cooling down not warming up
