Glacier projections
Graham Cogley (2012) regularized a number of projections of glacier wastage in a recent book (so that all numbers include the glaciers peripheral to the ice sheets, and cover the entire 21st century). …

Ice sheets and Semi-empirical models
Here I demonstrate that a very simple Semi-empirical model (SEM) can approximate the historical contribution to sea level rise from Greenland as estimated by Box and Colgan (2013). I start with a very …

Hurricane surges in tide gauges
The hurricane surge index was constructed by extracting the hurricane surge signal from tide gauge records. This involved some pre-filtering of the tide gauge data. This page illustrates a number of …

Changing Sea level budget and Semi-Empirical models
It is expected that the balance of the sea level budget will change in the future as the slow giants of the ice sheets awaken. This has been leveled as a criticism of semi-empirical models. For that …

Linear response of ice sheets?
Bamber & Aspinall 2012 made an expert elicitation of ice sheet experts. They shows this table in their supplementary information:

Trends in extreme hurricane damage
I have downloaded the ICAT damage estimates of normalized hurricane damages(/losses) and looked at the trends in the data. This series is often used to argue that there is no significant trend in …

Can process models close the sea level budget?
Before we can trust the projected models of sea level rise then it is reasonable to demand that these models can match the record of global mean sea level rise. Gregory et al. (2012) writes: …

Return period of Boulder 2013 extreme rain
!Several media stories on the Colorado floods talk of it as a 1000-year flood. However, the original source of this claim was talking about a 1000-year precip event (not the same as a flood-event). …

WAIS collapse during the last interglacial?
There are several lines of evidence pointing to a WAIS collapse during the last interglacial (MIS 5 / Eemian).

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 …

A rebuttal to Pielke Jr's 18ft critique.
We show in our paper that the surge index correlates with major land falling hurricanes with a correlation coefficient of 0.6. As expected this correlation improves with smoothing (see paper or table …
