The daily mail is just crap, there's no doubting that.

In this particular case, however, I don't think this is a daily mail problem, it's simply how science works. Most studies make statistics and then a 95% confidence interval, which in theory meand that 5% of them are wrong. But this is the least of our concerns, as in practice statistical biases are much more common than confidence intervals that miss the real value of the estimated parameter.

You'll find studies saying the climate is changing and studies saying it's not. You'll find studies saying that chloroquine works against coronavirus and others saying it doesn't.

Don't look at a single study. Look at scientific consensus instead. Yes, the climate is changing. No, chloroquine does not work against coronavirus. Do eggs cause diabetes? Idk, it's not clear with so little information. We need more studies and experts drawing conclusions from them.
