West Antarctic collapse in the IPCC reports
I have extracted some quotes from the IPCC reports since 1990 showing how West Antarctic Ice Sheet collapse has been discussed over time. It is not an exhaustive list.

Review of global glacier volume estimates
This is an updated version of the regularized global glacier volume estimates from Cogley (2012). I have included 2 new estimates: one by myself (G13) and another from Huss and Farinotti (HF12). These …

Vulnerability of marine based sectors of Antarctica
Should we take the risk of Antarctic collapse seriously? The IPCC AR5 sea level chapter considered instability of marine-based sectors of the ice sheets to be unlikely (Church et al., 2013). However, …

AR5 sea level rise uncertainty communication failure
I am disappointed in how the sea level rise projection uncertainties are presented in the IPCC AR5. The way the numbers are presented makes people believe 98 cm by 2100 is a worst-case scenario which …

Upper limit for sea level projections by 2100
We construct the probability density function of global sea level at 2100, estimating that sea level rises larger than 180 cm are less than 5% probable. An upper limit for global sea level rise of 190 …

Haar wavelet analysis of climatic time series
In order to extract the intrinsic information of climatic time series from background red noise, in this paper, we will first give an analytic formula on the distribution of Haar wavelet power spectra …

What does "likely" mean?
It can be quite difficult to interpret what likely exactly means sometimes. For example in the AR5 sea level chapter they report a likely range of 21-33 cm for thermal expansion (RCP8.5 table 13.5). I …

Volcanic impact on sea level and the global water cycle
We examined the impact of the 5 & 9 most major volcanic eruptions on global sea level. We construct a record of sea level and its uncertainty since 1854. From this we isolate the volcanic …

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 …
