Most Scientists 'Can't Replicate Studies By Their Peers' (bbc.com)
Science is facing a "reproducibility crisis" where more than two-thirds of researchers have tried and failed to reproduce another scientist's experiments, research suggests. From a report: This is frustrating clinicians and drug developers who want solid foundations of pre-clinical research to build upon. From his lab at the University of Virginia's Centre for Open Science, immunologist Dr Tim Errington runs The Reproducibility Project, which attempted to repeat the findings reported in five landmark cancer studies. "The idea here is to take a bunch of experiments and to try and do the exact same thing to see if we can get the same results." You could be forgiven for thinking that should be easy. Experiments are supposed to be replicable. The authors should have done it themselves before publication, and all you have to do is read the methods section in the paper and follow the instructions. Sadly nothing, it seems, could be further from the truth.
If you can't reproduce it, it's either fake or you were just being sloppy. Either way, it's no wonder ordinary civilians have doubts.
Or it took years to perfect the experiment technique. It took me 2.5 years to get my injury model and staining protocol optimized for my PhD research. A fair amount of success comes down to technique, not the written protocol.
Many studies have been done on anthropic climate change, but almost no experiments.

The infrared absorption of carbon dioxide is experimentally measured in the laboratory. And there is a vast amount of measured data on the earth's atmosphere and climate, from surface, atmospheric, and orbital probes, not to mention probes of other planets; and we acquire terabytes of additional data every year.
The basics of Earth's energy balance are well understood, and they are understood, in part, because of this vast amount of experimental and observational data.

There's one rather large experiment going on right now. Unfortunately we're all inside the test tube. So far it's turning out more or less how we expected.
This of course presumes the experiment **can** be replicated.
As for "peerless", there have been researchers at top labs (Bell, for one) that have fabricated their research.
Record high temps, record low temps. record rain, record drought.
That's actually what you'd expect with a chaotic system built of multiple random variables. It would be unnatural for weather to always be the same.
Actually it's not. It's a simple fact that in a stable system, as time goes on, there are fewer and fewer "record" events because each new record needs to be more extreme than all previously recorded events. Over time, record-breaking events decline significantly. So, an increase in record events is, by itself, evidence that the system is undergoing change.
