An estimate of global glacier volume
I assess the feasibility of multi-variate scaling relationships to estimate glacier volume from glacier inventory data. Scaling laws are calibrated against volume observations optimized for the …

Projected Atlantic hurricane surge threat from rising temperatures
Detection and attribution of past changes in cyclone activity is hampered by biased cyclone records due to changes in observational capabilities. Here we relate a new homogeneous record of Atlantic …

Semiempirical and process-based global sea level projections
We review the two main approaches to estimating sea level rise over the coming century: physically plausible models of reduced complexity that exploit statistical relationships between sea level and …

Homogeneous record of Atlantic hurricane surge threat since 1923
Detection and attribution of past changes in cyclone activity are hampered by biased cyclone records due to changes in observational capabilities. Here we construct an independent record of Atlantic …

Gulf Stream and ENSO Increase the Temperature Sensitivity of Atlantic Tropical Cyclones
Controversy exists over the role of the recent rise in sea surface temperatures (SST) and the frequency of tropical cyclones or hurricanes. Here, 135 yr of observational records are used to …

The historical sea level budget
We analyze the global sea-level budget since 1850. Good estimates of sea-level contributions from glaciers and small ice caps, the Greenland ice sheet and thermosteric sea level are available over …

Continuous monitoring of summer surface water vapour isotopic composition above the Greenland Ice Sheet
We present here surface water vapor isotopic measurements conducted from June to August~2010 at the NEEM camp, NW-Greenland (77.45° N 51.05° W, 2484 m a.s.l.). Measurements were conducted at 9 …

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 …

Potential for bias in 21st century semi-empirical sea level projections
We examine the limitations of a semi-empirical model characterized by a sea level projection of 73 cm with RCP4.5 scenario by 2100. Calibrating the model with data to 1990 and then simulating the …

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 …

Sea level projections to AD2500 with the RCP scenarios
Sea level rise over the coming centuries is perhaps the most damaging side of rising temperature (Anthoff et al, 2009). The economic costs and social consequences of coastal flooding and forced …

Efficacy of geoengineering to limit 21st century sea-level rise
Geoengineering has been proposed as a feasible way of mitigating anthropogenic climate change, especially increasing global temperatures in the 21st century. The two main geoengineering options are …
