Sentences with phrase «global paleo record»
So for global paleo record we should switch to Loehle 2007, and for longer time span the Greenland drill record is not bad as well.

A working group known as PALSEA2 (Paleo constraints on sea level rise) used past records of local change in sea level and converted them to a global mean sea level by predicting how the surface of the Earth deforms due to changes in ice - ocean loading of the crust, along with changes in gravitational attraction on the ocean surface.
Such researchers then proceed to rely on Global / Regional / Local Circulation Models in order to make projections of modern SLR even when these same models have not been able to reproduce numerous examples of abrupt SLR found in the paleo - record, thus clearly indicating that current models are not capable of identifying the modern risk of abrupt SLR.
Re «I believe, sudden, rapid, and sever global cooling is possible and likely based on the paleoclimatic and paleo - geomagnetic records.»
I believe, sudden, rapid, and sever global cooling is possible and likely based on the paleoclimatic and paleo - geomagnetic records.
Laboratory experiments show coral bleaching with increased temperature, but the Red Sea example, the paleo record, the variety of corals and alga, the other factors with bleaching, lack of a global coral biomas measurment and many other factors mean we should keep our panties on.
But, again, the CET record (even as extended by Tony) is the only real continuous regional temperature record we have prior to the mid-19th century so, ignoring paleo data (which are arguably less representative than the CET) it's the best «proxy» we have for a global temperature prior to ~ 1850.
After these threats are identified for each resource, then the relative risk from natural - and human - caused climate change (estimated from the global climate model projections, but also the historical, paleo - record and worst case sequences of events) can be compared with other risks in order to adopt the optimal mitigation / adaptation strategy.
There is LOTS of evidence for a global MWP (studies from all over the globe using different paleo methodologies, composite studies from several sites, historical records from all over the civilized world at the time, actual physical evidence, etc..)
An evaluation of the status of late Holocene sea level rise constructions is provided in a recent proposal by an international group of sea level experts (including Kopp), entitled: Towards a unified sea level record: assessing the performance of global mean sea level reconstructions from satellite altimetry, tide gauges, paleo ‐ proxies and geophysical models.
Searching for past regional extreme events through the historical and paleo records should be the focus, rather than working to air brush the past global variability.
Early TRL projects focused on establishing long tree - ring records from temperature - sensitive boreal forest locations in North American for studies of global change, using dendrochronologically dated wood, to investigate the value of stable isotope ratios in cellulose as paleo - thermometers and developing the necessary computer software for processing the data.
I simply explain that I do indeed deny CAGW, the accuracy of of climate models, the accuracy of reported global average temperature records, and paleo proxies....
That CET appears to be a good — but not perfect - proxy of global temperatures can be seen in the paleo and instrumental record.
Coupled global climate models, such as those that participated in the Paleoclimate Modeling Intercomparison Project (PMIP)(Jansen et al., 2007), in combination with improved paleo - climate records have led to better appreciation of the extent of extreme events that have occurred in the past (e.g., Cook et al., 2010b).
