Failure to rein in climate change and bolster sea defences could jeopardize up to a fifth of the world's economic output by the end of the century, as flooding threatens coastal countries worldwide, according to a study released on Thursday.
Britain is likely to experience hotter, drier summers and warmer, wetter winters by the 2070s, as well as rising sea levels which can lead to floods, due to the effects of climate change, long-term projections by the Met Office show.
