Choose you own scientific experiment: Triggering debris flows and flash floods
Landslides and flash floods result in many fatalities around the globe. Understanding what triggers these events is therefore vital, although how to approach this problem is not straight forward. After background information for the experiment and some guidelines, two options are presented to learn more about the triggers of debris flows: (A) using rainfall or (B) the atmospheric conditions. You …
Can somebody clear the air? How air quality and climate change are connected.
Erika von Schneidemesser
Air pollution and climate change are different phenomena, but are connected in a number of ways. The same sources emit both air pollutants and greenhouse gases, many air pollutants affect the Earth’s energy balance and thereby affect climate change, and a changing climate will affect air quality. Policy options to address either air quality or climate change cannot be formulated …
What do historical temperature records tell us about natural variability in global temperature?
Patrick T Brown
Global average surface air temperature can change when it is either ‘forced’ to change by factors such as increasing greenhouse gasses, or it can change on its own through ‘unforced’ natural cycles like El-Niño/La-Niña. In this paper we estimated the magnitude of unforced temperature variability using historical datasets rather than the more commonly used computer climate models. We used data …
Are humans to blame for the heat experienced in Geneva in the summer of 2015?
Since the dawn of the Industrial Revolution, humans have been changing the chemical composition of the atmosphere by burning fuels such as coal, oil, and natural gas. These gases are known to scientists as “greenhouse-gases”. Greenhouse-gases are vital to sustain life on Earth, but rapidly increasing concentrations of them can have catastrophic consequences. The word ‘catastrophic’ is perfectly fitting here, …
Global warming might be on hold, but it’s not cancelled
Instrumental measurements of surface temperatures are available back to around 1850. Based on these, we can estimate the annual mean global temperature. Global temperatures are clearly rising, mainly because of increasing amounts of greenhouse gases, like for example CO2 and methane, from use of coal, oil and gas and deforestation. Since 1998, a paradox seems to have appeared, where the …
