The Royal Society has released a new guide which outlines a retreat from its former vanguard stance on the threat of climate change and man-made global warming. The decision to update their scientific guide came after 43 of its members complained that the previous versions failed to take into account the opinion of climate change sceptics.
The new guide, entitled ‘Climate change: a summary of the science’, concedes that there are now major ‘uncertainties’ regarding the once sacred ‘scientific consensus’ behind man-made global warming theory, admitting that not only is it impossi

Great post! I so agree, its just that they should have spoken louder sooner.
I do believe that there is a large body of them that may have been silenced, threatened, coercerd
and even bribed in the last ten years of the Global Warming Madness.
In view of the ongoing public and political debates about climate change, the aim of this
document is to summarise the current scientific evidence on climate change and its
drivers. It lays out clearly where the science is well established, where there is wide
consensus but continuing debate, and where there remains substantial uncertainty

The Daily Mail is your source? It's a joke of a Right-Wing paper from the UK. No-one there takes the Daily Mail seriously... Do you have a real source of any kind?

I'm not so sure they should completely back off, clearly we ARE going through climate change, it's just that humans have NOTHING to do with how or why it is happening.

Look first, speak afterwards.
Of course, here ya go! From the horses mouth itself.

There is strong evidence that the warming of the Earth over the last half-century has
been caused largely by human activity, such as the burning of fossil fuels and changes
in land use, including agriculture and deforestation.
Measurements show that averaged over the globe, the surface has warmed by about 0.8oC (with an uncertainty of about ±0.2oC) since 1850. This warming has not been gradual, but has been largely concentrated in two periods, from around 1910 to around 1940 and from around 1975 to around 2000.
Global-average CO2 concentrations have been observed to increase from levels of around 280 parts per million (ppm) in the mid-19th century to around 388 ppm by the end of 2009.
Evidence from ice cores indicates an active role for CO2 in the climate system.
Changes in atmospheric composition resulting from human activity have enhanced the natural greenhouse effect, causing a positive climate forcing.
Once atmospheric CO2 concentrations are increased, carbon cycle models (which simulate the exchange of carbon between the atmosphere, oceans, soils and plants) indicate that it would take a very long time for that increased CO2 to disappear;
In addition to changes in greenhouse gas concentrations, there are a large number of less well characterised contributions to climate forcing, both natural and humaninduced.
The more complex climate models, supported by observations, allow climate sensitivity to be calculated in the presence of processes that amplify or reduce the size of the climate response.
When only natural climate forcings are put into climate models, the models are incapable of reproducing the size of the observed increase in global-average surface temperatures over the past 50 years. However, when the models include estimates of forcings resulting from human activity, they can reproduce the increase.
As with almost any attempts to forecast future conditions, projections of future climate change depend on a number of factors. Future emissions due to human activity will depend on social, technological and population changes which cannot be known with confidence. The underlying uncertainties in climate science and the inability to predict precisely the size of future natural climate forcing mechanisms mean that projections must be made which take into account the range of uncertainties across these different areas.
As noted above, projections of climate change are sensitive to the details of the representation of clouds in models. Particles originating from both human activities and natural sources have the potential to strongly influence the properties of clouds, with consequences for estimates of climate forcing. Current scientific understanding of this effect is poor.
Additional mechanisms that influence climate sensitivity have been identified, including the response of the carbon cycle to climate change, for example the loss of organic carbon currently stored in soils.
There is currently insufficient understanding of the enhanced melting and retreat of the ice sheets on Greenland and West Antarctica to predict exactly how much the rate of sea level rise will increase above that observed in the past century for a given temperature increase.
The ability of the current generation of models to simulate some aspects of regional climate change is limited, judging from the spread of results from different models; there is little confidence in specific projections of future regional climate change, except at continental scales

Thanks for the link showing how stupid the deniers are.
