If we do not seriously move away from burning fossil fuels, hurricanes like Melissa will only become worse. Already today Melissa tested the limits of what preparedness and adaptation can do. These limits are very real for everyone in the Caribbean. www.worldweatherattribution.org/climate-chan...

Warming Made Hurricane Melissa Four Times More Likely

One of the most powerful Atlantic storms on record, Hurricane Melissa has killed dozens of people and inflicted billions of dollars in damage.

Warming made the deadly hurricane four times more likely, a new analysis finds.

Climate Change Made Hurricane Melissa Four Times More Likely: Study Hurricane Melissa, which struck Jamaica as one of the most powerful storms ever recorded, was made four times more likely because of human-caused climate change, a rapid analysis said Wednesday.

"Adaptation to climate change is vital but it is not a sufficient response to global warming. The emission of greenhouse gases also has to stop."

This is how climate injustice unfolds. There is both an economic logic to cutting emissions now & a moral imperative to rapidly scale up international finance for loss and damage and adaptation in the most vulnerable countries.

"If you consider that Pakistan's role in total emissions is less than 1%, it's a big case of climate injustice," he says
