However, this in itself is not enough to define what level of warming is «dangerous,» especially since the projections of actual impacts for any level of warming are highly uncertain, and depend on further factors such as how quickly these levels are reached (so how long ecosystems and society have had to respond), and what other changes are associated with them (eg: carbon dioxide concentration, since this affects plant photosynthesis and water use efficiency, and ocean acidification).

In Addendum: Climate Change Impacts in the United States (pp. 26 - 28), Michaels and his colleague Chip Knappenberger discuss those studies in greater detail and also illustrate with two graphs how the IPCC AR4 warming projections should be adjusted in light of more recent climate sensitivity research.

Skipjack tuna fisheries in the western Pacific warm pool will not be drastically impacted by climate change in the next 50 years, according to projections with an ocean model that divides the ocean into a high - resolution 10 km grid.

«If, say, 50 % of the warming in the last 50 to 100 years has been natural, then this profoundly impacts our projections of human - caused warming in the future, slashing them by about 50 %.»

«There is no science demonstrating that the mid-point of the standard IPCC projection of a warming of 3 degrees if CO2 - e doubles from the 1750 level of 280 ppm will have any adverse impacts, if only because there is as yet no unambiguous empirical evidence of any such adve...

This article documents the design of the half a degree additional warming, projections, prognosis and impacts (HAPPI) experiment.

The purpose of this report is to quantify, with the most robust projections possible, the related climate impacts (including changes to climate extremes) associated with warming.

Climate scenarios from the Half a degree Additional warming, Projections, Prognosis and Impacts project (HAPPI) are largely consistent with transient scenarios extracted from RCP4.5 simulations of the Coupled Model Intercomparison Project phase 5 (CMIP5).

From this uncertainty in the attribution of past warming it follows that the IPCC projections of future warming and its impacts are even more «uncertain».

However, these adaptations will not necessarily reduce all of the negative impacts of climate change, and the effectiveness of adaptations could diminish at the higher end of warming projections.

The Challenge Imposed by Climate Change: observed changes, interpretation, projections, limited future warming, key messages and impacts.

Results from an irreducibly simple climate model,» concluded that, once discrepancies in IPCC computer models are taken into account, the impact of CO2 - driven manmade global warming over the next century (and beyond) is likely to be «no more than one - third to one - half of the IPCC's current projections» — that is, just 1 - 2 degrees C (2 - 4 deg F) by 2100!

So, if it turns out that the real net feedback from clouds is now negative or even strongly negative, this will obviously have a major impact on the 2xCO2 CS and all the future warming projections.

«Studies linking emissions to climate change impacts provide the most stringent test available for evaluating the accuracy and confidence of our projections of impacts in a future warmer world,» says Wolfgang Cramer, Director of the Mediterranean Institute for Marine and Terrestrial Biodiversity and Ecology in Aix - en - Provence, France.

Many also question the scientific validity of the IPCC projections of future anthropogenic warming and its consequences, especially the IPCC premise that these are likely to result in serious negative impacts, i.e. a serious potential threat to humanity and our environment, unless actions are undertaken to curtail human GHG emissions (principally CO2).

The impact on our «understanding and attributing climate change» is major, of course: if up to 50 % of past warming can be attributed to solar forcing (as many solar studies have concluded) then the whole model - predicted (2xCO2) climate sensitivity estimates are in serious question and, with these, all the projections for future climate change caused by AGW.

Since the negative impacts from global warming / climate change scale with the magnitude of the temperature rise, lower projections of future warming should lead to lower projections of future damages.

The post is really independent of the IPCC warming projections / sensitivity; it is about the impacts and incorrect attribution to human caused global warming
