The denier cult tells you that, but they tell you wrong.
For example, way back around 1988, the warming was predicted to be about 0.20C/decade. It ended up being 0.19C/decade. Nearly perfect.
Other predictions, spot on. Sea level rise. Stratospheric cooling. Decreased outgoing longwave in GHG bands. Increased backradiation. The tropospheric "hotspot". Polar amplification. Antarctic sea ice expansion before a decline. A lot of it very non-obvious, and all of it right. Impressive indeed.
In contrast, your side generally lacks the guts to predict anything. The only thing you've been willing to predict in the past 40 years is imminent cooling, and that's always been totally wrong.
