The technology of positioning ourselves with satellites, called GNSS (Global Navigation Satellite System) positioning, is now inseparable from our lives. If we apply high-precision analysis technology for GNSS positioning, we can see the plate tectonics at a cm/year-order speed. When this high-precision observation is performed... click to read more

In November 2019, world media reported floods in Venice with the highest water levels in the region in more than 50 years (peaking at 1.87m above mean sea level). The mayor of Venice tweeted "These are the effects of climate change... the costs will be... click to read more

Einstein's general theory of relativity predicted that gravity not only acts between two masses but also affects light which has no mass. We cannot see this effect in everyday life, but when light travels over vast intergalactic distances and is affected by the incredibly large... click to read more

The Antarctic ice sheet has been losing ice at an increasing rate. It remains unclear whether this mass loss will further accelerate over the coming decades. The continent of Antarctica is vast, bigger than the US and Mexico combined, and because it is so cold... click to read more

We often hear about how the warming climate is affecting the natural world around us. But the human-made global change is a tremendously more complicated problem than "just" a changing climate. It captures pollution, invasive species, biodiversity loss, excessive use of species or land, all... click to read more
