Surface lakes on Greenland will spread further inland as the climate warms
Amber A Leeson
Each summer, a rash of lakes forms from ponded meltwater on top of the Greenland ice sheet. These ‘supraglacial’ (on top of ice) lakes can drain through the ice sheet, delivering their contents to its base. The ice sheet slides on a thin film of water, and when extra water is added to this film (for example from a draining …
Could climate engineering save the Greenland Ice Sheet?
Patrick J. Applegate and K. Keller
Engineering the climate through albedo modification (AM) could slow, but probably would not stop, melting of the Greenland Ice Sheet. Albedo modification is a technology that could reduce surface air temperatures through putting reflective particles into the upper atmosphere. AM has never been tested, but it might reduce surface air temperatures faster and more cheaply than reducing greenhouse gas emissions. …
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 …
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 …
A new way to quickly estimate climate change impacts on rivers and streams
Julie A. Vano and Meghan M. Dalton
We outline a new method that offers quick insights into how the amount of water in rivers and streams will be impacted by warmer temperatures and future precipitation change. This method yields comparable results to more conventional model-intense climate change impact studies and is faster and cheaper to implement, making it a practical alternative for those exploring future water supply …
