An infinite supply of carbon free energy.
Sounds really nice, right? But there are apparently some pitfalls with that…

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.

Relative importance of mass and volume changes to global sea level rise.
We examine the relationship between 50-year-long records of global sea level (GSL) calculated from 1023 tide gauge stations and global ocean heat content (GOHC), glacier and ice sheet melting. The …

Wavelet Coherence FAQ
I have written a new FAQ for the Crosswavelet and Wavelet Coherence matlab package. At the moment the questions answered are:

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 …

Neglible Solar Forcing of Climate at Multi-year and Decadal Periods.
We examine possible links between solar cycle irradiance variations the large atmospheric circulation systems that affect whole planet’s climate. In particular we examine the putative mechanism of …

ENSO propagation towards the poles.
We present observational evidence of the dynamic linkages between ENSO and Northern Hemisphere (NH) ice conditions over the past 135 years. Using Wavelet Transform (WT) we separate statistically …

Holocene evolution of Scharffenbergbotnen blue ice area
We show that it is possible to extract a high-resolution (annual) paleoclimate record from the surface of a blue-ice area (BIA). The variability of the surface stable-isotope values suggests that …

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 …

Is there evidence for sunspot forcing of climate at multi-year and decadal periods?
It has been proposed that solar cycle irradiance variations may affect the whole planet’s climate via the stratosphere, the Quasi-Biennial Oscillation (QBO) and Arctic Oscillation (AO). We test this …

SSA enhancement of GPR data.
We present a novel method of improving signal-to-noise ratio in radargrams. The method uses singular spectrum analysis (SSA) to separate each individual radar trace into orthogonal components. The …
