Common arguments
Is the climate data manipulated?
People distrust institutions, and the idea of adjusted data sounds suspicious. Here is why that does not hold up.
Why it sounds plausible
People distrust institutions, and the idea of adjusted data sounds suspicious.
The simple answer
Multiple independent datasets show the same broad trend.
The fuller explanation
Temperature records are checked, adjusted transparently for known issues, and compared with satellites, oceans, ice and sea level. If all these independent indicators point in the same direction, the manipulation claim becomes much weaker.
Bottom line
You would need many unrelated measurements to be wrong in the same direction.
