Roundup: The soaring humanitarian costs of climate change

How to tackle the impacts of climate change is front and centre as world leaders, environmental activists, and concerned citizens young and not-so-young gather in New York, with the UN Climate Action Summit kicking off a week of debates and high-level meetings at the General Assembly on Monday. 

There’s a lot to discuss: A new study estimates that the number of people caught in humanitarian crises fuelled by climate change will nearly double if countries fail to limit rising global temperatures – inaction that could also cost billions in humanitarian responses.

The report, from the International Federation of Red Cross and Red Crescent Societies, estimates that some 200 million people will need humanitarian aid each year by 2050 due to climate-linked disasters. And the cost of responding to these emergencies could reach $20 billion every year, the report said. 

Monday’s climate summit is aimed at solidifying plans on how countries will meet commitments to shrink greenhouse gas emissions over the next decade and beyond.

But as our recent reporting indicates, the humanitarian consequences of a warming world are already evident, often in countries and communities with the fewest resources to adapt. Super-charged storms, longer-lasting floods, more frequent drought, and searing heatwaves are already intensifying food insecurity, resource-related conflict, and displacement, climate experts say.

So as 16-year-old climate activist Greta Thunberg leads a brigade of young people from 150 countries in a “climate strike” on 20 September, spend some time with our latest coverage on how climate change is already having a humanitarian impact around the world.
