Hello, and welcome to NewsHour.
It's coming to you live from the BBC World Service studios in London.
I'm Tim Franks.
In a couple of weeks at the annual UN Climate Summit, there'll be a lot of talk about trying somehow still to limit global warming to 1.5 degrees centigrade, a target which we're currently way off track from hitting.
The reason I'm mentioning it now is that a new report out today by a team of researchers called the World Weather Attribution Team at Imperial College London has said that the current level of warming, just over 1 degree above pre industrial levels, has already caused immense devastation since 2004.
The team calculates that more than half a million people have been killed by extreme weather events in Asia, Africa and Europe.
These disasters can clearly be shown, they say, to be fueled by a warming climate.
The latest torrent of deaths has come in Spain, with emergency teams continuing to search for those still missing.
After flash floods killed at least 95 people, the country's Prime Minister, Pedro Sanchez, has been visiting areas in the southeast of the country hit by the floods.
I would like, first of all, after this meeting to pass on to the people who live in Valencia and also Castellon, please.
The high altitude isolated depression continues.
Please do not go out, stay home, follow the alerts from the emergency services.
Follow all their requirements, all their recommendations, because at the moment, the most important thing is to save as many lives as possible.
