Here’s the best graphic I’ve seen for putting the numbers in context: https://xkcd.com/1732/
It’s slightly out of date so we’re actually at roughly +2 degrees C.
Basically, from year 0 CE to 1000 CE there was basically no change in average temperature. Then from 1000 CE to 1900 CE temperature actually went down about .5 degrees. Since then, we’ve gone up 2.5 degrees. So the past two thousand years temperature changed a total of .5 degrees down. We’ve increased about 5 times that in the past 100 years.
Agree 100%. Especially when you’re doing more complicated queries, working with ORM adds so much complexity and obfuscation. In my experience, if you’re doing much of anything outside CRUD, they add more work than they save.
I also tend to doubt their performance claims. Especially when you can easily end up mapping much more data when using a ORM than you need to.
I think ORMs are a great example of people thinking absolutely everything needs to be object oriented. OO is great for a lot of things and I love using it, but there are also places where it creates more problems than it solves.
