Climate Action

Future global warming will lead to an increase in ‘extreme sea levels’, with consequent flood risks to coastal infrastructure and human populations. An international research team from Italy, Greece, the Netherlands (TU Delft / Deltares) and the UK published this new research in Nature Communications.

Researchers have found that the bedrock below the West Antarctic Ice Sheet is rising much more rapidly than expected, revealing a very different Earth structure than previously believed. This discovery has important implications in understanding climate changes in Antarctica. The team of researchers, from ten universities including TU Delft, report on their findings in Science on June 22th.

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.

The 4TU.Federation has awarded a total of 22 million euros to five proposals within the framework of the call ‘High Tech for a Sustainable Future’, thus giving a strong impetus to research into sustainable technology.

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.
