When a great deal of the projections for the future are based on computer models, it behooves researchers to make first-rate models and that's the drive in the current paper. (Science Daily: Improving prognoses for a sustainable future)
Computer models play a significant role in environmental policy, but offer only a partial picture of the industrial system Whether it's electric automobiles, renewable energy, carbon tax or sustainable consumption: Sustainable development requires strategies that meet people's needs without harming the environment. Before such strategies are implemented, their potential impact on environment, economy, and society needs to be tested. These tests can be conducted with the help of computer models that depict future demographic and economic development and that examine the interplay between industry and the climate and other essential natural systems.
Together with his Norwegian and US colleagues, junior professor Dr. Stefan Pauliuk at the Faculty of Environment and Natural Resources at the University of Freiburg undertook the hitherto most comprehensive review of five major so-called integrated assessment models. Published in the scientific journal Nature Climate Change, the team's results show that these models exhibit substantial deficits in their representation of the industrial system, which may lead to flawed estimates of the potential environmental impacts and societal benefits of new technologies and climate policies.

Ed: what is this? Do you support the climate change research or what?
I support the truth, whatever it brings.
Ed: aren't your the sanctimonious goombah?
Well, no, I don't think so since what other answer is there. That's why we look to their paper to discover whatever they bring us.
Note: the sciencers often write like they're on Facebook (i.e. they never use paragraphs) but I do modify the formatting somewhat to improve readability although never their text.
Integrated assessment models create scenarios for the most cost-effective transition toward a sustainable supply of materials and energy while taking the planetary boundaries into consideration. "The scenarios generated by the models are an important instrument for environmental policy-making," says Pauliuk. "They show that it is technically feasible to achieve a central goal in global climate policy: Namely, to limit average global warming to a maximum of two degrees Celsius compared to the level at the beginning of the Industrial Era."
As a consequence, the model results were important during the preparatory negotiations leading up to the Paris Agreement that came into effect in November 2016 with the intention of mitigating climate change. The models' results also play a significant role in the latest assessment report issued by the Intergovernmental Panel on Climate Change (IPCC), where they are used to link the mitigation options described for different sectors such as buildings, transport, or energy supply.

There wasn't much of a segue and there was nothing between the first excerpt and the second but my read is the first segment dealt possibly with individual assessment studies whereas the second segment is reviewing the result of integrating them.
"Because the models' results are so important to decision makers, the questions arises about their validity and robustness," says Pauliuk. As a result, the researchers paid particular attention to the way in which the models represent the industrial system; that is, the global value chain of production, processing, and use of energy, materials, and consumer goods as well as recycling. The industrial system is the source of all human-made goods. At the same time, it is also the origin of all emissions to the natural environment.
But the representation of the industrial system in these models is incomplete, according to the researchers. "In particular, the cycle of materials, for instance of iron and copper, but also the representation of urban infrastructure is completely missing," explains Pauliuk. This fact may lead may limit the predictive capacity of the models but more research is needed: "It remains to be shown how ignoring core parts of the industrial system influences the feasibility of certain scenarios to mitigate climate change. In addition, important strategies to reduce emissions such as recycling, material efficiency, or urban density have not been considered at all." Researchers are now called to expand the models to more accurately describe the cycle of materials and other details concerning the industrial system. The ultimate goal is to obtain more realistic prognoses for climate and resource policies.

The reading is a bit thick but the Rockhouse does not apologize for that whereas an apology would be due you if I were to insult you with pre-digested pap regarding whatever I think may be in the contents.
Ed: what if these are state scientists whose purpose is to undermine the credibility of climate change research with intimidating language?
Now you're jiving, Tall Daddy. Question everything.
