Climate change: Huge toll of extreme weather disasters in 2021

In May, a storm named Yaas wreaked havoc in India and Bangladesh.

According to a new report, weather events linked to a changing climate brought misery to millions around the world.

The study found that 10 extreme events caused more than $1 billion of damage.

Hurricane Ida hit the US in August, and flooding in Europe in July.

In poorer regions, floods and storms caused mass displacements of people.

Not every extreme weather event is caused by or linked to climate change, although scientists have become bolder in exploring the connections.

Dr Friederike Otto, one of the leading researchers, said earlier this year that every heatwave happening in the world now is made more likely and more intense by human-caused climate change.

Climate change is affecting storms and hurricanes.

The first part of the sixth assessment report was published in August.

The authors said they had high confidence that the evidence of human influence has strengthened.

The study said that the proportion of intense tropical cyclones, average peak tropical cyclone wind speeds, and peak wind speeds of the most intense tropical cyclones will increase on the global scale with increasing global warming.

Hurricane Ida hit the US a few weeks after that report came out.

The state of New Jersey was flooded in the wake of Hurricane Ida.

It was the most destructive weather event of the year according to Christian Aid.

Thousands of people in Louisiana were evacuated from the path of the storm.

New York issued a flash-flood emergency alert for the first time because of the huge amount of rain that fell.

95 people died and the economic losses are $65 billion.

The water was fast and powerful, and it overwhelmed defences, killing more than 200 people. The reported damages were $43 billion.

Most of the weather events in the list occurred in developed countries.

The train was hit by debris in Austria.

Financial losses from insurance claims are usually available in richer countries where people can afford to pay for insurance.

Natural catastrophes have cost more than $100 billion in the last five years, according to Aon.

The report shows many events where the financial impact is harder to determine, but where the impact on people is significant.

Over one million people were displaced by flooding in South Sudan, while 200,000 had to flee to escape a tropical storm in May.

"That's a huge human impact," said the report author.

Losing your home, your livelihoods, and everything, and not having the resources to rebuild is incredibly tough. If you have insurance, you can build that back.

The need for increased efforts to curb emissions of carbon dioxide is highlighted in the report. It wants global climate diplomats to help poorer countries that suffer huge economic losses by putting their money where their mouths are.

The issue of finance for loss and damage caused by climate-related events saw major disagreement between countries. The richer nations said we need more talks on the question.

Hundreds of thousands of people were forced to leave their homes in South Sudan.

"Although it was good to see the issue of loss and damage become a major issue at COP26, it was bitterly disappointing to leave without a fund set up to actually help people who are suffering permanent losses from climate change."

"Bringing that fund to life needs to be a global priority in 2022."
