The subglacial hydrology of the coldest continent on the planet is giving climate experts a peek at the future.

The UV Index is calculated by a computer model which takes into account ozone concentrations, altitude, latitude, day and time of year, solar irradiance (incoming energy from the sun) and UV surface ...

The sun may rise every morning, but the amount of sunlight reaching the Earth’s surface can substantially vary over decades.

Solar radiative energy declined in large parts of the world from the 1950s to the 1980s - known as "global dimming" - before a partial recovery since.

“Implications are serious: the increased open water lowers the average albedo [reflectivity] of the planet, accelerating global warming; and we are also finding the open water causing seabed ...

To reflect an object, you need a mirror line. When a shape is reflected, its size does not change - the image just appears 'flipped'. Every point on the shape is the same distance away on the ...

Clinging to the flanks of Mount Palcaraju, the glacier has, like most in the Peruvian Andes, been melting rapidly in recent ...

Global mean surface warming throughout the 21st century will be largely determined by cumulative emissions of carbon dioxide (CO 2) and the other long-lived greenhouse gases, and what proportion of ...
