MORE INFORMATION regarding carbon dioxide on our planet. There is NO CO 2 in this image of the Bayswater power station in NSW. This picture, so beloved by TV programmers to support a message of dirty coal and CO 2 emissions, is in fact water vapour in cooling towers. Stop it!!
MORE INFORMATION regarding carbon dioxide on our planet. From: wattsupwiththat.com Y axis From: Archibald, D. 2007, Climate Outlook to 2030 Energy and Environment Doubling of CO2 produces only a fraction of degree of warming by the greenhouse effect (SEE RED LINE ON THE y AXIS. FROM HERE TO HERE X axis CO2 is increasing steadily in our atmosphere, at a rate of about 1ppm per annum; the inset shows how CO2 varies from summer to winter. In the past, CO2 levels have been much higher e.g. 5000ppm or more, without any evidence of runaway global warming This graph is said to be ‘logarithmic”. It shows that 20 ppm of CO2 will produce some degree of warming, shown as about 1.5 o C in this graph. Note that if one was to double the CO2 content from 180 to 360ppm, then temperature rise would be a small fraction of a degree (see the vertical axis); a doubling of present levels of CO2 would cause almost no temperature rise. This is an example of the law of diminishing returns. 17
