地球上的一天越来越长，这可能会对互联网产生破坏性影响
原子钟显示，一天的长度正在变长。但科学家还不清楚其中的原因；气候变化、天气和潮汐的摩擦效应也许能够解释地球自转受到了何种影响；专家认为，如果地球白天的时间延长，那么我们可能需要引入前所未有的“负闰秒”，而这有可能对互联网产生破坏性影响。
I am Professor of Polar Geodesy and ARC Future Fellow at the University of Tasmania. My field of expertise is geodetic observation of Earth deformation and the global water cycle, including ice-sheet mass balance and sea-level change and particularly using the Global Positioning System (GPS) and the Gravity Recovery and Climate Experiment (GRACE). I also work on reduction of systematic and random errors in these techniques in order to maximise the information content in the data and improve the reliability of the interpretations. I have authored more than 80 peer-reviewed publications including several articles in the leading scientific journals Science, Nature, Nature Geoscience, Nature Climate Change and Proceedings of the National Academy of Science. In 2015 I was awarded the Royal Society (London) Kavli Medal and Lecture (see the lecture at https://royalsociety.org/events/2015/04/continental-loss).

Longer days on Earth could break the internet - here's how
Atomic clocks have revealed that the length of a day on Earth is suddenly getting longer - it's a mystery to scientists and could lead to a 'negative leap second'.

Antarctica is losing sea-ice at record levels. It's time to pay attention
The melting of ice sheets in the Arctic this summer is unprecedented. But its southern counterpart poses a much more serious threat to sea levels.

We shouldn't be worried about the huge Antarctic iceberg, it's the little glaciers behind it
Icebergs breaking off Antarctica, even massive ones, do not typically concern glaciologists. But the impending birth of a new massive iceberg could be more of a problem.
