A new study published in Big Earth Data presents phenological metrics derived from Earth observation (EO) satellite time series—such as greening onset, senescence, and growing season length—which are essential for crop monitoring but challenged by the massive scale of EO data exceeding local processing capacities, and introduces a free, open-source Web Crop Phenology Metrics Service (WCPMS) built on the Brazil Data Cube platform for server-side extraction from large datasets. It further demonstrates the tool’s effectiveness by estimating soybean sowing dates in Brazil using phenological metrics and validating the results against field data.

The appointment recognises his expertise at the intersection of AI, weather and climate science, and strengthens Singapore’s contribution to international efforts in this space.

Global sea levels may rise faster than previously expected, a new study suggests. The reason is that warming oceans appear to be melting Antarctic ice shelves from below much more rapidly than expected.

Ice shelves, which are extensions of gigantic glaciers that float on the water surface, act like buttresses that slow the flow of gigatons of ice into the sea. Now, researchers in Norway have discovered that long, channel-like grooves on the underside of these ice shelves can trap relatively warm ocean water. This sharply increases local melting.

The study has global implications. If Antarctic ice shelves thin and weaken, the downhill journey of the ice behind them can accelerate, fast-forwarding the process in which huge amounts of ice cascade into the ocean, causing sea levels worldwide to rise far faster than currently projected.

This dynamic has already been observed elsewhere in Antarctica. The Intergovernmental Panel on Climate Change (IPCC) has flagged polar ice shelf instability as a major but poorly understood risk factor that could lead to sea level rise that is far more rapid and severe than most current models predict.

Effective science communication is a powerful but underrated tool. Metaphors, a common literary device, draw connections between unlike things and are often conceptually, innately understood. In science and science communication, these figures of speech act as a means of structuring concepts to provide the basis for further exploration. The use of metaphors in science can be a catalyst for change, invention, and, unfortunately, misunderstanding. Metaphors should be used responsibly when attempting to make complex scientific concepts easily understandable, and should weigh the accuracy and accessibility of information in a favorable balance.
