Global warming in an independent record of the last 130 years

Key Points

Mostly a proxy study but as they use an index comprised of "170 temperature-sensitive proxy time series (corals, ice cores, speleothems, lake and ocean sediments, historical documents)," and correlates tightly with calibrated instrument records where there is overlap, this seems fairly rigorous. Of course their methodology and data will have to be fully vetted in field peer-review now that the paper has cleared editorial publication peer-review and has been published in GEOPHYSICAL RESEARCH LETTERS.
Global warming in an independent record of the last 130 years
http://www.agu.org/pubs/crossref/pip/2012GL054271.shtml
Key Points
- Global warming is observed in an independent record of the past 130 years
- Vets upward trend in thermometer record including two periods of upward trend
- Paleo data with physical links to temperature can be used without calibration
