In virtually all parts of the world glaciers are retreating, and this is often considered to be one of the clearest signs of global warming (e.g. Leclercq and J Oerlemans, 2011). Glaciers started to shrink in the second half of the 19th century and, apart from some minor interruptions, this development has continued until today. Over the past hundred years glacier melt has made a significant contr ...[Read More]

Note by the editors: In the unique period our world is currently facing, we have decided to open our blog to hear the voices of our young climate scientists from around the globe. This is an opinion piece provided by two early career climatologists from Argentina and the Netherlands. I just arrived at home with a bunch of groceries from the supermarket after encountering some very empty shelves. I ...[Read More]

The recent coronavirus outbreak (i.e., nCovID-19; Fig. 1) has caused global panic, along with widespread travel bans, home quarantines and country-wide lockdowns. The World Health Organization (WHO) declared nCoVID-19 as a pandemic as of March 11th, 2020 (WHO, 2020). To tackle this global health crisis, scientists are attempting to synthesize a vaccine, while countries are trying to mitigate the n ...[Read More]

One often hears that ambitious climate policy might be premature while climate change is still “uncertain”. This sounds like a fair argument: The amount of global warming per doubling CO2 is not well constrained, and the amount of economic damage per degree of warming even less. But is this uncertainty a sound excuse to wait and see? Uncertainty, risk aversion, and insurance If you knew the ...[Read More]
