Vanderford Glacier (Credit: Monash SAEF) Governments have a crucial 30 to 50 year window to plan for rising sea levels using dependable computer models, before Antarctic ice melt becomes far harder to predict.Scientists say current Antarctic ice loss can guide sea-level planning until mid-century, but forecasts become far less certain later as retreat may accelerate….

At first glance, Neptune seems like the last place where violent weather should thrive. The ice giant circles the Sun at an average distance of about 4.5 billion kilometres, leaving it in a region where daylight is remarkably faint. Even at midday, the sunlight reaching Neptune would resemble a dim twilight compared with conditions on…
