Recent public discussion of climate change and summaries and popularizations of the work of CRU and others often contain over- simplifications that omit serious discussion of uncertainties emphasized by the original authors. For example, CRU publications repeatedly emphasize the discrepancy between instrumental and tree-based proxy reconstructions of temperature during the late 20th century, but presentations of this work by the IPCC and others have sometimes neglected to highlight this issue. While we find this regrettable, we could find no such fault with the peer-reviewed papers we examined
In other words, as has been noted, the numbers from the tree rings don't match the numbers from the stations over a given period of time. (As it turns out, in this period of time, the tree rings show a markedly lower temperature than their data sets of instrument readings show.) The issue isn't whether they've "highlighted this issue" in "presentations of this work" -- they have; they're more than willing to say "yeah, the tree rings don't support global warming trends over period of time X". The issue is that they've unceremoniously dumped these tree ring data from their data sets, for no apparent better reason than that it doesn't fit their preconceived conclusions! That's what you should be looking into! Not whether they say "tree ring data and instrument data diverge", but whether they're justified in dumping the data that diverges from their pet theories!!!
1. The global temperature will increase - predicted by Hansen's model from early eighties. There is an observed increase in temperature.
That's not an AGW prediction, that's also a predication based on us just coming out an ice age. Try again please.
2. Arctic and antarctic to warm faster than rest of the planet - predicted by all models. Observed.
That's not an AGW prediction, it's a prediction of warming no matter what the source. Try again please.
3. Troposphere to warm and stratosphere to cool - predicted by all models. Observed.
And yet again, not an anthropogenic prediction, but a prediction for the increase of many GHG's from a great many reasons.
4. Increasing signature of CO2 in long wave spectrum form top of atmosphere. Observed by satellite spectrographically.
Which is not an AGW prediction, but a prediction tied to increased CO2 concentrations. The nature of the correlation is hardly well spoken to.
5. Increasing acidification of the oceans. Observed.
Strike 5.
and plenty more where those came from. Please cut the crap about climate science not being falsifiable. Try looking at the evidence, the science and the facts for a change.
Please present the 'others' then. The real trick to AGW as a theory is falsifiable predictions are hard to come by. Virtually all the observations and data that can be gathered about it still rely on an understanding of the relationship between human CO2 emissions and global CO2 concentrations, and then from global CO2 concentrations to long term climate trends. It's easily proven that increased CO2 increases warming. Demonstrating that human activity has introduced so much new CO2 as to cause historically unprecedented warming requires extraordinary proof. I've yet to find any articles claiming evidence above the level of suggestive.
