Sensible heat has significantly affected the global hydrological cycle over the historical period

Multiple lines of evidence indicate widespread changes to the global water cycle since 1950. Here we show, using a range of climate modelling results, that changes in sensible heat are the dominant contributor to the present global-mean precipitation change since preindustrial time.

Half of flooding damage left uninsured

Flooding events are hitting many parts of the world, causing big infrastructure damage. But flooding can also have large indirect costs for the global economy. In a new report, CICERO analyses the total costs of four flooding events. An increasing share of costs are left uninsured, the authors warn.

Double trouble: Climate change and air pollution

Smog is already damaging crops in northern India. What  will happen when both air pollution and temperature increase?
