Extreme weather events routinely have detrimental socio-economic impacts around the globe. In fact, weather-related events make up over 90% of natural disasters worldwide [1]. In the new millennium, the frequency of many extreme weather events such as droughts and high temperatures, has systematically exceeded the levels seen in the 1980s and 1990s [1], and anthropogenic …[Read More]
Climate: Past, Present & Future
The ocean floor is sinking under the weight of sea level rise
Sea level rise is one of most dreadful consequences of anthropogenic (caused by humans) global warming. It is estimated that the loss of coastal infrastructure alone would cost the global economy more than 1 trillion dollars per year by 2100 [1]. This number is based on climate models, but these are only as good as …[Read More]
Desert loess: formation, distribution, geoscientific value
Loess is an aeolian (wind-driven) silty sediment covering over 10% of the Earth’s land surface; it occurs predominantly in the mid-latitudes. On a global scale, loess is among the most widespread unconsolidated sediments, and of crucial importance for agricultural regions where loess deposits are known to form fertile soils because of its ability to store …[Read More]
InterArctic project: understanding the interaction between artic environments and societies
The InterArctic project (Fig. 1) focuses on vulnerability, resilience and adaptation of northern societies facing global change. The current rapid warming of Arctic and Subarctic climates has already produced many changes in the social, economic and cultural behaviour of the populations inhabiting these regions and more changes are expected to come. In this context, looking …[Read More]
Climate models and Bach’s unfinished fugue
Johann Sebastian Bach’s last work – Contrapunctus XIV – is an unfinished musical composition. For many years, scholars considered that this piece was left unfinished because of Bach’s deteriorating health in his final years and eventual death. However, researchers recently found evidence that Bach might have left this piece intentionally unfinished, as he thought that …[Read More]
Learning lessons from the past to inform the future
A fairly recent blog post here reiterated the compelling comparison between the current COVID-19 crisis and the ongoing climate emergency, focusing on extreme events such as hurricanes, heatwaves and severe rainfall-related flooding, all of which are likely to get worse as the climate warms (Langendijk & Osman 2020). This comparison has been made by …[Read More]
Breathing life into a d(r)ying lake in northwest Iran
Lake Urmia, in Northwest Iran, was once the most extensive and permanent hypersaline lake (salinity >> of ocean) in the world. Since 1995, the lake water level has dropped about 8 m, shrinking to less than 30% of its original surface area and losing more than 90% of its water volume over two decades [1]. …[Read More]
Glacier retreat and music
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. …[Read More]
Hurricane COVID-19: What can COVID-19 tell us about tackling climate change?
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 …[Read More]
Weather hidden within dusty parchments and weighty tomes—historical climatology and its contribution to our understanding of the past climate
What is historical climatology? Historical climatology is an interdisciplinary research field between paleoclimatology and the historical sciences, that explores the archives of societies to examine the climate of the past. Archives of society mean all man-made remains of the past in contrast to archives of nature. The latter represent physical remains of natural processes such …[Read More]
