Can coral reef islands survive sea level rise?

Sea-level rise will expose coastal communities around the world to increasingly destructive coastal erosion and flooding. This is especially true for coral reef islands, which are low elevation accumulations of loose sand and gravel that have become populated throughout the tropics. For atoll nations like... click to read more

Storm surge extremes are so SPATIAL

On hearing the term climate change, very often, what comes first to mind is rising temperatures, sea-level rise, or ice melting in Greenland and Antarctica. Only after catastrophic weather hazards, such as those associated with severe storms, the debate turns into the impact of climate... click to read more

Digging up a dinosaur in a galaxy cluster

Galaxy clusters are the biggest gravitationally-bound objects in the Universe, millions of light years across, some as massive as a quadrillion (10^15) suns. They contain thousands of galaxies and are filled with 100-million-degree plasma, so tenuous it is a million times less dense than the... click to read more

Arid lands transform abruptly as aridity increases

Climate change poses a concrete threat to arid ecosystems, in which water is limited (it rains less than 65% of what is evaporated). These dry ecosystems cover almost half of the terrestrial surface and are predicted to go through increased aridification, which endangers the plants... click to read more

More droughts, more war?

Historically, violent conflicts tend to predominantly erupt in bad years, when droughts, floods, or heatwaves put the functioning of societies to the test. Does this mean that violent conflicts will become more frequent as extreme weather becomes increasingly common, globally, because of climate change? While each... click to read more
