All in all the science of hurricanes does appear to be much more fun and interesting than the average climate change issue, as there is a debate, a «fight» between different hypothesis, predictions compared to near - future observations, and all that does not always get pre-eminence in the exchanges about models.

The models and observations both also indicate that the amplitude of interannual variability about these longer - term trends is quite large, making it foolhardy, at best, to try to estimate the slope of anthropogenic warming from a few years of data (as you seem to advocate).

I suspect that it looked OK in your view or you didn't check; «the paper i cited talks of the hiatus in global temperatures for the past 20 years or so, that the Little Ice Age was global in extent, and that climate models can not account for the observations we already have let alone make adequate predictions about what will happen in the future.

There are many who will not like this recent paper published in Nature Communications on principle as it talks of the hiatus in global temperatures for the past 20 years or so, that the Little Ice Age was global in extent, and that climate models can not account for the observations we already have let alone make adequate predictions about what will happen in the future.

The GRACE observations over Antarctica suggest a near - zero change due to combined ice and solid earth mass redistribution; the magnitude of our GIA correction is substantially smaller than previous models have suggested and hence we produce a systematically lower estimate of ice mass change from GRACE data: we estimate that Antarctica has lost 69 ± 18 Gigatonnes per year (Gt / yr) into the oceans over 2002 - 2010 — equivalent to +0.19 mm / yr globally - averaged sea level change, or about 6 % of the sea - level change during that period.

Consequently, short of waiting until after climate change has occurred, the best guide we have for judging model reliability is to compare model results with observations of present and past climates.Our lack of knowledge about the real climate makes it difficult to verify models.

Evaluating ocean and atmospheric observations with advanced modeling tools, scientists from NOAA and CIRES found that about 60 percent of 2016's record warmth was caused by record - low sea ice observed that year, and the ensuing transfer of ocean heat to the atmosphere across wide expanses of ice - free or barely frozen Arctic Ocean.

With all the talk this week about future climate — the global warming imagined by IPCC crystal ball models, that is — the focus for many is rightly on the gulf between predictions and observations that have taken place so far.

If only GHG forcing is used, without aerosols, the surface temperature in the last decade or so is about 0.3 - 0.4 C higher than observations; adding in aerosols has a cooling effect of about 0.3 - 0.4 C (and so cancelling out a portion of the GHG warming), providing a fairly good match between the climate model simulations and the observations.

As others have noted, the IPCC Team has gone absolutely feral about Salby's research and the most recent paper by Dr Roy Spencer, at the University of Alabama (On the Misdiagnosis of Surface Temperature Feedbacks from Variations in Earth's Radiant Energy Balance), for one simple reason: both are based on empirical, undoctored satellite observations, which, depending on the measure required, now extend into the past by up to 32 years, i.e. long enough to begin evaluating real climate trends; whereas much of the Team's science in AR4 (2007) is based on primitive climate models generated from primitive and potentially unreliable land measurements and proxies, which have been «filtered» to achieve certain artificial realities (There are other more scathing descriptions of this process I won't use).
