The Australian's interview with Pachauri covered (link)
topics that included this year's record northern summer Arctic ice growth, the US shale-gas revolution, the collapse of renewable energy subsidies across Europe and the faltering European carbon market, Dr Pachauri said no issues should be off-limits for public discussion.
"People have to question these things and science only thrives on the basis of questioning," Dr Pachauri said.
"If you look at temperatures going back 150 years, there are clearly fluctuations which have occurred largely as a result of natural factors: solar activity, volcanic activity and so on.
- The Earth continues to warm strongly. Scientists assess this based on long term observations of the heat content of the ocean, the air temperature (an indicator of the heat content of the atmosphere), and the amount of heat absorbed by the land, glaciers, ice sheets and sea ice.
- Understanding changes in climate requires data over long time periods, at least 30 years and preferably much longer.
- The best measure of global warming is ocean heat content as it absorbs nearly 90% of additional heat trapped by greenhouse gases. Global ocean heat content has increased substantially over the last 40 years, and the strongly upward trend has continued through the most recent decade up to the present.
- Singling out short term trends in air temperature to imply that global warming is not occurring is incorrect and misleading.

Well not according to IPCC chief Pachauri! Not according to the UK Met Office! (link) Not according to HadCruT 3 and 4.
Depending on which data set used, the stall in global warming is 16, 17 even up to 23 years. If no warming for another 7 years, what will Mr Flannery and Mr Steffen say then?

Most of the warming in the twentieth century occurred before 1945, when carbon dioxide levels began to increase rapidly. When carbon dioxide levels began to increase rapidly after 1945, the earth began a 30 year cooling cycle -- just the opposite of what should happen with the greenhouse gas theory. Both carbon dioxide levels and temperature increased together from 1976 to 1998, but that proves nothing.In fact, it was during this period of cooling that "a high-priority (US) government report warned of climate change that will lead to floods and starvation."

‘A Study of Climatological Research as it Pertains to Intelligence Problems’, written by the CIA for ‘internal planning purposes’ in August 1974, goes a little way towards explaining why some people over a certain age experience a sense of déjà-vu when climate change is mentioned; in the mid-1970s there really was a lot of scientific discussion about global cooling. With the benefit of hindsight, reading it makes one feel wry and embarrassed. So many of the terms bandied about 35 years ago are still being employed by today’s fear-mongers, about the very opposite phenomenon.
