On a daily basis we can see and feel the dramatic influence water vapour, as a greenhouse gas, has on daily temperature variations. We can go from a record overnight frost to near record daily temperatures in a period measured in hours. How anyone can claim that CO2 is the major influence when it's claimed influence is is so miniscule compared to these daily variations, and it's impact is a fraction of a degree measured over decades is beyond me. Every time we experience a frost it should be obvious that all the heat supposedly trapped by greenhouse gases is being radiated back out into space, totally lost, in the space of a few hours simply because of the absence of water vapour in the atmosphere. Move into another region experiencing cloud cover and the effect is just the opposite. If frosts were becoming less frequent and less severe then perhaps there may be something preventing this rapid and total loss of heat, but they are in fact becoming more frequent and more severe all around the world.
On a longer time frame we can see and experience the effect that ocean currents and sea surface temperatures have on our rainfall. I find it difficult to understand why our own Bureau of Meteorolgy have yet to come to terms with the influence that the Indian Ocean Dipole has on our weather when Japanese researchers have long proven the direct connection. BOM instead clings to the Pacific ENSO which statistics show has a more coincidential relationship than a direct influence. I find it alarming that the supposedly qualified scientists who are so ignorant of the impact of the oceans that lap our shores are so certain that some miniscule volume of a gas in the atmosphere is the major driving force of our climate, and the information that they provide which reflects this, is accepted by many who blindly accept simply because BOM is supposedly staffed by people with a lot of letters after their names.
Some years ago I noticed a relationship between the weather patterns in Indonesia and in SE Australia. The droughts in both places seemed to coincide. I approached a number of BOM scientists who all dismissed it as coincidence. The I met a private weather forecaster, who had left BOM some years previously because he felt they were focusing on the wrong data, and he confirmed that indeed there was a direct connection through the Indian Ocean which provided a direct relationship to the weather over a large portion of Australia, as well as Indonesia, India, Africa and Japan. Since then, Japanese researchers who have been at the forefront of research into the Indian Ocean and in fact discovered the Indian Ocean Dipole have been increasingly researching it and now are able to accurately computer model the changes in the Ocean behaviour and it's influence on the weather.
The moral of the story, be wary of those experts that know not what they know not.
