10 Sept 2019 - Investing $1.8 trillion over the next decade - in measures to adapt to climate change - could produce net benefits worth more than $7 trillion.
This is according to a global cost-benefit analysis setting out five adaptation strategies.
The analysis was carried out by the Global Commission on Adaptation - a group of 34 leaders in politics, business and science.
They say the world urgently needs to be made more "climate change resilient".
- 12 years to save the planet? Make that 18 months
- Big lifestyle changes needed to cut emissions
- Climate change is 'shrinking winter'
The commission, led by former UN Secretary-General Ban Ki-moon, World Bank chief executive Kristalina Georgieva and Microsoft co-founder Bill Gates, argues that it is an urgent moral obligation of richer countries to invest in adaptation measures that will benefit the world.
The report says those most affected by climate change "did least to cause the problem - making adaptation a human imperative".
Its primary aim is to put climate change adaptation on to the political agenda around the world. And to do this, it sets out "concrete solutions" and an economic plan.
