Reconstructing global sea level
Better estimates of historical Global Mean Sea Level (GMSL) can help us understand many components of the climate system. It is a key climate record.

Trends and acceleration in global and regional sea levels since 1807
We use 1277 tide gauge records since 1807 to provide an improved global sea level reconstruction and analyse the evolution of sea level trend and acceleration. In particular we use new data from the …

Eemian interglacial reconstructed from a Greenland folded ice core
Efforts to extract a Greenland ice core with a complete record of the Eemian interglacial (130,000 to 115,000 years ago) have until now been unsuccessful. The response of the Greenland ice sheet to …

Persistence Matters: Significance of paleoclimatic reconstruction statistics
Proxy data forms natural time series used to lengthen instrumental climatic records, and may contain a significant portion of autocorrelation. Increased serial correlation limits the number of …

Unprecedented low 20th century winter sea ice extent in the Western Nordic Seas since A.D. 1200
We reconstructed decadal to centennial variability of maximum sea ice extent in the Western Nordic Seas for A.D. 1200-1997 using a combination of a regional tree-ring chronology from the timberline …

Comment on the subsidence adjustment applied to the Kemp et al. proxy of North Carolina relative sea level
Kemp et al. obtained a really nice proxy of relative sea level from North Carolina. North Carolina is subsiding and they therefore apply a ‘GIA’ correction to obtain a sea level record …

Recent global sea level acceleration started over 200 years ago?
This paper has turned out to be quite popular. It made the frontpage of GRL, got an editorial highlight, and reached the top downloads of the AGU journals when it was published.

Sulfate source inventories from a Svalbard ice core record spanning the Industrial Revolution.
In this paper we use sliding multiple linear regression techniques between the different chemical species and sulphate and use the changing loadings to infer how the sulphate sources have varied over …

Present day summers in Svalbard are as warm as those during the medieval warm period.
Snow pits sampled during two consecutive years (2001, 2002) at the summit of Lomonosovfonna ice cap in central Spitsbergen, Svalbard, showed that ion concentrations were spatially homogeneous. The …

Virtual station reconstruction of global sea level.
We analyze the Permanent Service for Mean Sea Level (PSMSL) database of sea level time series using a method based on Monte Carlo Singular Spectrum Analysis (MC-SSA). We remove 2–30 year …
