Historic instrumental temperature records can be found here on my web site together with a variety of related articles. (wattsupwiththat.com)
On several blogs these past three years, I've been talking up the value of the early instrumental temperature records, the historical, and anecdotal records. (judithcurry.com)
However, temperature estimates derived from tetraethers in modern soils from Svalbard, Norway (MAT ≈ — 4 °C) were within 2 °C of instrumental temperature records (MAT ≈ — 6 °C), suggesting that tetraethers are an effective proxy for reconstructing temperatures from paleosols at high latitudes (Peterse et al., 2009).
