Climate change: some reasons for our failures – the guardian
Academic Robert Manne knew evil human beings were responsible for catastrophic global warming 25 years ago.
“..primarily through the burning of fossil fuels human beings were responsible for potentially catastrophic global warming.”
“And yet, since Kyoto, greenhouse gas emissions have risen very steeply. The level of carbon dioxide in the atmosphere—280 parts per million before the industrial revolution—is now 400 parts per million.”
Two minor points Manne glossed over:
- OVER the past 15 years air temperatures at the Earth’s surface have been flat while greenhouse-gas emissions have continued to soar. In other words, there has been no atmospheric global warming since 1998 despite a substantial increases in green-house gas emissions.
- A US Government NOAA report found the summer drought of 2012 was not caused by manne-made global warming but by natural variations in the weather. Manne’s emotional lead photo of a drought ravaged, dried-up marsh thus rendered alarmist propaganda. The NOAA study was released in March 2013. Manne’s article published 22 July 2013. Plenty of opportunity for due diligence. A second NOAA paper submitted to the American Meteorological Society also found the US record heat-wave of 2012 was due to natural variation and not caused by manne-made carbon dioxide emissions.
