Antarctica ramps up sea level rise

Ice losses from Antarctica have increased global sea levels by 7.6 mm since 1992, with two fifths of this rise (3 mm) coming in the last five years alone.The findings are from a major climate assessment known as the Ice Sheet Mass Balance Inter-comparison Exercise (IMBIE), to which TU Delft also contributed, and are published today in Nature.

Take geo-engineering seriously as an emergency brake to combat global warming

Geo-engineering. The idea is cropping up increasingly often in answer to the question: what can we change on Earth to curb global warming? First and foremost, we must do everything we can to reduce emissions of greenhouse gases around the world. The Paris climate agreement is an important step in the right direction, but more and more studies are showing that the promises made by the signatory countries will have insufficient effect. So we need to find a quicker way to reduce greenhouse gas emissions but, unfortunately, the global community isn't prepared to do that just yet. At some point, we may need geo-engineering whether we like it or not. The sooner we carry out research into the practical aspects of geo-engineering, the possible pitfalls and the consequences, the better prepared we will be for the future.

Ruisdael Observatory: measuring the Dutch atmosphere on a 100m scale

‘Weather’ is the result of a combination of many diverse factors, such as solar radiation, the concentration of greenhouse gases, air quality and humidity, local building density or vegetation, wind direction and a whole host of underlying physical and chemical processes.

Inaudible infrasound also useful for weather and climate forecasts

Research by Pieter Smets of TU Delft and the KNMI shows that infrasound can be used for weather and climate forecasts. These inaudible low sound waves can be used to gain a better picture of the stratosphere, which can barely be measured in any other way. On Wednesday 28 March, Smets will be awarded his PhD at TU Delft for his work on this subject.

Increasingly accurate picture of accelerating rise in sea levels

Rising sea levels are affected by all kinds of different factors, most of which we can now effectively unravel and explain almost everywhere in the world. This is according to TU Delft researcher Thomas Frederikse, who has also established that the average rise in sea levels worldwide is accelerating. Moreover, the days on earth are becoming slightly longer... Frederikse will be awarded his doctorate on Monday, 19 March.

Context and Goals of Sentinel-5P and TROPOMI

The TROPOMI instrument launches this Friday on board Sentinel-5 Precursor payload. But why is TROPOMI that important for the atmospheric composition scientific community? And why is it a “precursor”?
