I am assuming the move against CO2 is only because of its implication in temperature rise. Is anyone really suggesting that CO2 is a pollutant or poisonous?

Temperature

The recent 30 year trend is upward but different areas experience different trends. There have been plenty of downward 30 year trends in the last 2,000 years. We may still be cooler than the Medieval Warm Period. The present is the coolest in the last 8,000 years. We are lucky to be in a habitable interglacial period between the much longer ice ages.

The Pause

The Global Climate Models did not predict such a pause so if The Pause exists it is a black mark against the models.

Greenhouse Effect
The datasets presented seem to suggest that there is not much danger looming from the direct greenhouse effect without amplifying feedbacks.
Temp CO2
The 35 years of the satellite era shows correlating overall trends but no correlation on shorter timescales. #?br? Detrending to remove the 2-3ppm annual increase shows some correlation but big failures. #?br? The large annual change of CO2 in the Arctic seem to be caused by sun and temperature.
The last years 150 shows generally matching trends but temperature has variations unrelated to CO2.
From 1935 to 1980 CO2 levels accellerated but there was no trend in temperature.
Similarly from the Law Dome ice core, from 1800 to 1995 CO2 levels accellerated but there was no trend in temperature.
The Vostok ice core shows temperature and CO2 to be highly correlated at the 100,000 year scale with rising temperature leading CO2 by 500 years and falling CO2 lagging considerably more.
At the 500,000,000 scale there was no correlation.

CO2 Emissions
Australia's emissions are totally insignificant.
Only China, USA, India and perhaps Russia really matter.
There may be huge natural flows in the annual cycle that dwarf human emissions and are poorly understood.

Rainfall
Rainfall hasn't changed much in 110 years. It decreases in hot years and in El Ninos

Snow And Ice
Correlate fairly well with temperature. Increasing in the Northern hemisphere where temperatures are rising and decreasing in the Southern hemisphere where temperatures are falling.
The changing snow and ice covers don't seem to suggest any direct relation to CO2 other than indirectly via Temperature.

The behaviour of the Lower Stratosphere is quite different to the Lower Troposphere.
