Even the mainstream majority believe that the climate models are wrong as cooling has been measured in the Pacific.
The Russian theory attempts to account for this.
This is an article from the Bulletin of Atomic Scientists:

Take, for example, ocean warming. Despite criticisms from climate change skeptics, global climate models have accurately predicted rising average sea surface temperatures, which are extremely important to predicting the intensity of climate change. But observations in recent decades show that changes in sea surface temperatures vary greatly by region. That geographic variation suggests that**** end of century global warming may be less severe than most climate models suggest. ****These observations do not invalidate climate modeling, but they do highlight the importance of regular comparisons between climate models and the real-world observations they aspire to reflect.
**>She adds that observed trends show a strong cooling trend in the Eastern Pacific and Southern Ocean, which goes against what the models predicted. **
No, the discussion is on why they would do lie not are they lying.
