Time scales of atmospheric circulation response to CO2 forcing

By Paulo Ceppi An important question in current climate change research is, how will atmospheric circulation change as the climate warms? When simulating future climate scenarios, models commonly predict a shift of the midlatitude circulation to higher latitudes in both … Continue reading

Why has there been a rapid increase in heat-related extremes in Western Europe since the mid-1990s?

By Buwen Dong In the last few decades, Europe has warmed not only faster than the global average, but also faster than expected from anthropogenic greenhouse gas increases (van Oldenborgh et al., 2009). With the warming, Europe experienced record-breaking heat … Continue reading

Changing wet and dry seasons

By Richard Allan The fickle nature of weather patterns is ultimately responsible for the where and when of tropical rainfall extremes which wreak damage on agriculture, infrastructure and people. Tropical cyclones, such as Enawo which battered Madagascar in March, can … Continue reading

Potential links between Arctic sea ice loss and mid-latitude weather: revisiting an influential earlier study

by Len Shaffrey The Arctic is changing rapidly due to human emissions of greenhouse gases. Arctic sea ice extent has been declining by 12% per decade since reliable satellite estimates began in 1979. By summer 2012, Arctic sea ice extent … Continue reading

Measuring radiation with aircraft

By Peter Hill In my career as an atmospheric scientist I’ve relied on observational data from a wide range of sources including satellite imagery, surface measurements, ground-based and satellite based radar, and aircraft measurements. Last July I had my first … Continue reading

Geoengineering – how could we detect its cooling effect?

By Eunice Lo Sulphate aerosol injection (SAI) is one of the geoengineering proposals that aim to reduce future surface temperature rise in case ambitious carbon dioxide mitigation targets cannot be met.  Climate model simulations suggest that by injecting 5 Tg of sulphur dioxide gas … Continue reading

From kilobytes to petabytes for global change research: take the skills survey!

By Vicky Lucas Institute for Environmental Analytics If you deal with megabytes of environmental sample data, or gigabytes of sensor data, or terabytes of model data or petabytes of remote sensing data, then I’d like you to take a survey.  … Continue reading

Producing quantitative estimates of radiative forcing

By Will Davies Last year the Paris climate conference agreed to an action plan to limit global warming to below 2 degC – preferably 1.5 degC. Various initiatives are measuring performance against this target – such as the global warming … Continue reading
