800% increase in UN appeal needs for extreme weather-related emergencies over last 20 years – new Oxfam research. The amount of money needed for UN humanitarian appeals involving extreme weather events like floods or drought is now eight times higher than 20 years ago — and donors are failing to keep up, reveals a new Oxfam brief today. For every $2 needed for UN weather-related appeals, donor countries are only providing $1. Average annual extreme weather-related humanitarian funding appeals for 2000-2002 were at least $1.6 billion and rose to an average $15.5 billion in 2019-2021, an 819 percent increase.
