UN reports controlling climate forcers can save millions - CO2 not mentioned

From the UN News Centre:
25 November 2011 –
More than two million lives can be saved each year by implementing the cost-effective measures presented in a United Nations report released today, which would help reduce black carbon, methane and ozone emissions. 
The report, issued by the UN Environment Programme (UNEP), provides a package of 16 measures that could not only save some 2.5 million lives each year but also avoid crop losses amounting to 32 million tons annually, and help keep the global temperature rise below the two degree Celsius target over the next 40 years.
The measures target emissions of black carbon, methane and ground-level ozone, also known as short-lived climate forcers (SLCFs), and their implementation would allow countries to save rather than spend resources and money. This is in part because a lot of measures allow for gases to be harvested as a source of clean fuel.
Black carbon, methane and ground-level ozone....not a mention of CO2. Has CO2 finally been declared innocent by the UN?

IPCC Wrong - New Peer-reviewed Paper

The Australian reports:

Climate forecasts 'exaggerated': Science journal

Also reported by the UK Mail on Line:
Apocalyptic predictions about climate change are likely to be wrong, a study says.
Dire forecasts by activists who say that carbon dioxide levels will 'double' and cause temperature rises of 10C are 'unlikely'.
Instead, the maximum increase is likely to be 2.6C. 
The ice age, 21,000 years ago, provided a 'clean' comparison where human activities had no effect on atmospheric levels of CO2.
The period was not as cold as previously believed.
Dr Schmittner told the Daily Mail that it would be ‘virtually impossible’ for a doubling of carbon dioxide to cause temperatures to rise by 8ºc or 10ºc.
From AFP:
"When you reconstruct sea and land surface temperatures from the peak of the last ice age 21,000 years ago -- which is referred to as the Last Glacial Maximum -- and compare it with climate model simulations of that period, you get a much different picture," said lead author Andreas Schmittner, an Oregon State University researcher.
"If these paleoclimatic constraints apply to the future, as predicted by our model, the results imply less probability of extreme climatic change than previously thought."
