In reporting criticism by some scientists that IPCC’s then-impending January report understates certain risks, particularly sea level rises, an AP story quoted Stefan Rahmstorfprofessor of physics and oceanography at Potsdam University as saying apm a way, it is one of the strengths of the IPCC to be very conservative and cautious and not overstate any climate change risk”.

Among the measures that might be used, there was high agreement and much evidence that policies that put a price on the cost of carbon wy1 could provide incentives for consumers and producers.

Improved crop and grazing land management to increase soil carbon storage; restoration of cultivated peaty soils and degraded lands; improved rice cultivation techniques and livestock and manure management to reduce CH 4 emissions; improved nitrogen fertilizer application techniques to reduce N 2 O emissions; dedicated energy crops to replace fossil fuel use; improved energy efficiency. AR4 WG3 chapter details: The now-published text gives a warning that the new estimation of sea-level could be too low: More efficient end-use electrical equipment; heat and power recovery ; material recycling and substitution; control of non-CO 2 gas emissions; and a wide array of process-specific technologies.

The Principles also state that “IPCC reports should be neutral with respect to policy, although they may need to deal objectively with scientific, technical and socio-economic factors relevant to the application of particular policies. AR4 WG1 chapter details: WGII describes some of what might be expected in the coming century, based on studies and model projections.

Retrieved 31 August Some critics have contended that the IPCC reports tend to be conservative by consistently underestimating the pace and impacts of global warming, [] and report only the “lowest common denominator” findings.

Pachauri responded in an interview with Science. The panel, however, made seven formal recommendations for improving the IPCC’s assessment process, including:. Biocovers and biofilters to optimize CH 4 oxidation. Cold days, cold nights, and frost events have become less frequent.
