Weather data has been collected for more than a lifetime. Accurate data has been recorded for over a century. No matter how deep you want to delve into the debate, the deniers don't seem to want to offer an alternate explanation for the sharp rise in temperatures since the beginning of the industrial era about 70 years ago, nor do they want to explain the linear correlation between such increase and the increase in atmospheric CO2. Coincidence maybe?
The frequency and magnitude of severe weather events is also higher than ever recorded.
1. And just how long is a century in terms of global ages and climate variations?
2. The Industrial Revolution is generally regarded as having started in the early 1800's, not just 70 years ago. Pollution from coal-burning was widespread and highly visible in cities such as London by the late 1800's.
3. The frequency and magnitude of weather events is reflected in the flood and drought events. We have flood and drought events measured in terms of;
1 in 20 year flood or drought events
1 in 50 year flood or drought events
1 in 100 year flood or drought events
1 in 200 year flood or drought events
1 in 500 year flood or drought events
These flood or drought events are recorded in flood heights, or lack of rainfall, and recognised by every authority from planning authorities, to agricultural authorities, to building authorities, and even recognised by scientists.
If these regular, extreme flood and drought events are recognised, why doesn't the GW/CO2 fraternity recognise and acknowledge that extreme climate events are linked to these flood and drought events?
The greatest heatwave in Western Australia happened during 1933, during the Great Depression (1929-1933), a period of the least industrial and human activity in the Nation.
Industrial activity in Australia was running at 1/3rd of the level of industrial activity prior to 1929, during 1933.
The heatwave records created during the 1933 W.A. heatwave have not yet been broken.
