1Vandaag: zeespiegelstijging in de Waddenzee

De Waddenzee is een uniek gebied in Nederland, waar zee, land en ecologie samenkomen. 1Vandaag vroeg mij naar de scenarios voor zeespiegelstijging voor de Waddenzee.

Catching up

Hello, long time no see!

So what's happened these past few months?

The IPCC Working Group 1 contribution to the Sixth Assessment report is getting up to speed. I attended the first lead author meeting in Guangzhou, China in June, and joined this months' second lead author meeting in Vancouver, Canada remotely. I am co-writing chapter 9 (Oceans, Cryosphere and Sea Level). It's quite an intense process, but I'm learning lots and have met some great people already!

In August I co-organised the iSLR18 conference in Utrecht. This conference was especially geared towards Early Career Researchers working in sea-level change. We had 2 conference days and 1 field day, plus a public debate evening.

In December, Dutch secretary Ingrid van Engelshoven, of Education, Culture & Science, visited NIOZ. She toured the facilities and learned about sea-level change, seaweed and building with nature solutions.

Earlier this month, I was one of the three speakers at the annual Brunings Lec…

It's Nature week

Something amazing happened this week: two publications with my name on it came out in Nature! 

First, I wrote an explained of a recent paper by Sally Brown and colleagues in Earth's Future for Nature News & Views.

What I found really cool about their paper, is that it not only shows the impact of future sea-level rise on the size of the flooding area and the amount of people impacted, but also the reverse: how people can have an impact on the amount of sea-level change by taking action. Their paper shows that the sooner we manage to cap our greenhouse gas emissions, the less sea-level rise we'll get.

Second, I am a co-author on a paper led by Chris Perry, on how coral reefs are losing the ability to keep track with sea-level rise

In this paper, we compared the vertical growth rate potential of over 200 tropical reefs to recent and projected rates of sea-level change. From this, we find that few reefs will have the capacity to keep tracking sea-level rise. This will lead to…

Selected as IPCC AR6 Lead Author

Some very exciting news: I've been selected to serve as a Lead Author on the next IPCC report!

The IPCC (the Intergovernmental Panel on Climate Change) is an international organisation of the United Nations. The IPCC provides comprehensive assessments of all the science related to climate change. These assessments have been done on a regular basis since 1990, when the first assessment report was brought out. I will be working on the Sixth Assessment report (AR6).

The report (and the workload) is split into three parts:
Working Group I: The Physical Science Basis
Working Group II: Impacts, Adaptation and Vulnerability
Working Group III: Mitigation of Climate Change
Due to my expertise on sea-level change, I have been asked to contribute to Working Group I, on Chapter 9: Ocean, Cryosphere and Sea Level Change.

The IPCC Assessment report is an overview of the state-of-the-art on climate science. This information will be communicated to governments and policy makers. It is therefore a very …

A month of firsts

So far, the year 2018 has brought me a lot of new experiences. 

For one, my first PhD student Tim Hermans (@HermansTHJ) has started with his project on high resolution sea-level modelling. It is a project in collaboration with the UK Met Office, who are providing us with some really cool data. Tim has made a flying start and I'm looking forward to working with him over the next few years!

Secondly, I was (for the first time) appointed chair of the organising committee of a conference: the ECR conference on "Impacts of sea-level rise from past to present", also known as iSLR18 (@iSLR18). This conference will be organised in Utrecht (Netherlands) from 26-29 August 2018. And the nice thing is: all participants will be Early Career Researchers (PhD in or after 2010)! We are inviting four great keynote speakers and four ECR scientists to give keynote presentations during the conference, and there will be a field trip and a public outreach event. All in all, we've had very …

NSO-GO grant awarded

Today it has been 5 years since I defended my PhD. I needed a friend to remind me of this, because it feels like it was a lifetime ago. I have since traveled the world, worked in some great places, met awesome people (you know who you are) and learned heaps. And yet it seems like it was only yesterday: I still feel like an 'Early Career Scientist'. But perhaps that's just me. 

On top of this being my 5-year PhD anniversary, I received the amazing news that I have been awarded an NSO-GO grant from the NWO. This grant is for 1 PhD student and will focus on sea-level change research using satellite observations. The student will be part of an international team, featuring co-supervisor Riccardo Riva (TU Delft), promotor Bert Vermeersen (NIOZ/TU Delft), Roderik van de Wal (IMAU), Jonathan Gregory (Univ. Reading) and John Church (UNSW).

A job ad for this position will go out in due course.. I'm looking forward to recruiting a new member for my research group here at NIOZ!

New paper in NHESS

Together with Dr. Renske de Winter and colleagues from Utrecht University, we published a paper on skewed distributions of contributions to sea-level change projections for 2100. This work is linked to a paper we published earlier this year, on the impact of skewed uncertainties on sea level allowances at tide gauge locations. Both papers show that it is very important to find out what the shape is of the uncertainty distribution of ice sheet contributions to sea-level change, as this affect high-risk/low-probability risks at the coast. 

Both papers were selected as highlight papers in their respective journals. The work has received significant attention in the Dutch press, for instance from the NOS and

Press release [in Dutch]

De totale range van zeespiegelstijging blijkt groter dan gedacht. Binnen 80 jaar kan een regionale stijging van 1,8 meter niet worden uitgesloten, door afname van de massa van de Antarctische ijskap. Dit concluderen onderzoekers van onder a…
