Do you think that in the same way that the Solanki et al paper on solar sunspot reconstructions had a specific statement that their results did not contradict ideas of strong greenhouse warming in recent decades, this (the fact that climate sensitivity projections are not best estimates of possible future actual temperature increases) should be clearly noted in media releases put out by scientists when reporting climate sensitivity studies?

In the end, I would hypothesize that the result of the freeing of data and code will necessarily lead to a more robust understanding of scientific uncertainties, which may have the perverse effect of making the future less clear, i.e., because it will result in larger error bars around observed temperature trends which will carry through into the projections.

186: Why did it not occur to you, as it did to me, that, since the IPCC's projections of future exponential CO2 growth and logarithmic temperature response necessarily produce a straight line, the IPCC's detuning of its own projections to reduce the projected temperature change to just 0.2 C ° / decade over the first couple of decades of this century has no basis in scientific reality or method?

Future projections show that, for most scenarios assuming no additional GHG emission reduction policies, atmospheric concentrations of GHGs are expected to continue climbing for most if not all of the remainder of this century, with associated increases in average temperature.

Given that the forcings from 1984 to present (as well as the temperature history) lie at or below the low end of the projections made in 1988, do you suppose that this will also prove to be true into the future?

But as illustrated in the figure below, simply extrapolating this correlation forward in time puts the Antarctic temperature in the near future somewhere upwards of 10 degrees Celsius warmer than present — rather at the extreme end of the vast majority of projections (as we have discussed here).

Earlier you said «This site has tiny handful of the predictions made and how they have failed» yet all the examples you have given appear to be about either projections of global temperatures, which I am sure others will pick up on if you want to push the issue, or the timespan we have available to take action to avoid committing ourselves to future consequences.

Hansen gave three different temperature projections, for three possible future GHG scenarios.

«Future projections based on theory and high - resolution dynamical models consistently suggest that greenhouse warming will cause the globally averaged intensity of tropical cyclones to shift towards stronger storms,» Knutson et al. (2010); Grinsted et al. (2013) projected «a twofold to sevenfold increase in the frequency of Katrina magnitude events for a 1 °C rise in global temperature.»

No, it translates to climate models can not accurately represent natural climate variability, which is why they can't project future global temperature at even the 2 % confidence level: «we find that the continued warming stagnation of fifteen years, 1998 - 2012, is no longer consistent with model projections even at the 2 % confidence level» — vonStorch (2013)

«Future generations will wonder in bemused amazement that the early 21st century's developed world went into hysterical panic over a globally averaged temperature increase of a few tenths of a degree, and, on the basis of gross exaggerations of highly uncertain computer projections combined into implausible chains of inference, proceeded to contemplate a roll - back of the industrial age,» Lindzen was quoted, offering praise for Christopher C. Horner's Politically Incorrect Guide to Global Warming and Environmentalism.

If we use these bases for a future projection, we end up with atmospheric CO2 at around 600 ppmv and an increase in temperature of around 2C (not 4C, as your curve projects).

Climate projections calculated in this paper indicate that the future atmospheric CO2 concentration will not exceed 610 ppm in this century; and that the increase in global surface temperature will be lower than 2.6 DegC compared to pre-industrial level even if there is a significant increase in the production of non-conventional fossil fuels.

It started with computer projections of future temperature rise along with changes in precipitation, soil moisture and so forth.

Such a temperature rise lies within the range of several future climate projections for the 21st century.

To a naïve observer of temperatures, the difference of temperature between day and night would lead the observer to make extreme projections for the very near future.

Clearly, observed temperature trends are predicting a future temp that resembles the IPCC projection if CO2 was held constant - the actual trends are multiple times below the «runaway» and «accelerating» global warming that Obama and the IPCC still push.

Based on our inferred close relationship between past and future temperature evolution, our study suggests that paleo - climatic data can help to reduce uncertainty in future climate projections.

The simulations were shown to reproduce the observed strong reduction in past crop yields induced by high temperatures, thereby confirming that they capture one main mechanism for future projections.

to project both how global average temperature will respond to future emissions and the associated uncertainty in those projections.

The discrepancy between recent observed and simulated trends in global mean surface temperature has provoked a debate about possible causes and implications for future climate change projections.

And finally, and perhaps most importantly, the future projection of temperature rise made by climate models (upon which the sea level rise projections are based) have been shown by a growing body of scientific research to be overestimated by about 40 percent.

If these results continue to be supported, then future projections of temperature change, as depicted in the present suite of climate models, are likely too high.

So the issues are the same as surface temperature observation versus naive projections of the near - future forcings.
