Energy system transformations for limiting end-of-century warming to below 1.5 [degrees] C

Many impacts projected for a global warming level of 2 [degrees]C relative to pre-industrial levels may exceed the coping capacities of particularly vulnerable countries. Therefore, many countries advocate limiting warming to below 1.5 [degrees]C. Here we analyse integrated energy-economy-environment scenarios that keep warming to below 1.5 [degrees]C by 2100.

A strong ultraviolet pulse from a newborn type Ia supernova

Type Ia supernovae are destructive explosions of carbon-oxygen white dwarfs. Although they are used empirically to measure cosmological distances the nature of their progenitors remains mysterious. One of the leading progenitor models, called the single degenerate channel, hypothesizes that a white dwarf accretes matter from a companion star and the resulting increase in its central pressure and temperature ignites thermonuclear explosion.
