The problem is that Haig ignores CO2 as a concept.
Nope, My view is CO2 is a vital plant food and a green house gas. It does have an effect on GW but that effect is insignificant compared to natural events such as another green house gas H2O and our variable star to name two.
To him, the sun is the only cause of temperature change, in the same way that it's his only cause for earthquakes.
Nope, My view is the variable Sun is the main driver of climate change not the only one. I've never said the Sun is the only cause of earthquakes or volcanoes and major weather events. The variable Sun appears to trigger those events.
Solar output is decreasing, thus the world is actually decreasing in temperature. All data to the contrary is somehow false.
Yes, to the first part and open to data, to the contrary, in the second part.
There is no debating with that.
Sure there is

UAH Global Temperature Report: July 2015 – the pause continues
Compared to seasonal norms, the warmest average temperature anomaly on Earth in July was in southeastern Kazakhstan near the city of Almaty. The July temperature there averaged 3.33 C (about 6.0 degrees F) warmer than seasonal norms. Compared to seasonal norms, the coolest average temperature on Earth in July was in the northern Atlantic Ocean off the southeastern coast of Greenland, where the average July 2015 temperature was 3.77 C (about 6.77 degrees F) cooler than normal.
