Hello. In paper Albert et al. in Forest Ecosystem (2015) is used RCM STARS II (Orlowski et al. 2008) end RCP, but in many present studies is used older system SRES without problems. Usually scientist combinate more models. My topic is forestry and I´m not sure for why do you want to predict climatic change. Kind regards Tomas

I agree with Aresh. SRESs are the past and RCPs the current IPCC model. You have to read about their comparability and use the latter with at least 2 scenarios and another different model if you want. 

The RCPs replaced the SRES since 2013, then I suggest you to use it...

Thankyou very much Arash, Gustavo and Efrain for your suggestions.

I agree, RCPs are the way to go. Because they are older, it is harder to get papers based on SRES results past journal reviewers and editors. However, some of the RCP scenarios are comparable to the older SRES scenarios. The following provides a comparison:

Dear Martyn, thanks for informing about paper highlighting the comparison of SRES and RCP. My question which GCM is presenting the climatic data with respect to RCP?

There are lot of GCMs (>10 ..search at CMIP5 coupled model) you can use. You can use all of them and average or ...in My experience...use 4 to 10 and select the 2 best represent you recent climate, e.g. 1979-2014 for the most important variable sof your study....or composite of them. The goodness of GCMs depends on the region. For my region Southeastern South America HADCM----- is good woith both SRES and RCP , we have use the german model in the past with SRES, and the australian and some USA GCMs for RCP. Some are good for temperature (most of them), very few for precipitation.

Best, Gustavo
