Extreme weather in 2021 has seen fires rage, rivers flood, ice melt and temperatures soar.

Climate change has reshaped life on planet Earth through the extreme weather, which has also included droughts and wild storms.

World leaders are gathering in Scotland to try to accelerate the fight to curb climate change.

So far, it is not working, as the world keeps getting hotter and its weather more extreme, according to scientists and government officials. They do not have to point far back in time or far off for examples.

Heatwaves proved deadly and unprecedented, with temperatures in the north-west US reaching 47C (116F) in Portland, Oregon, a city known for its mild climate. Meanwhile, Hurricane Ida paralysed New York City with record-breaking, deadly rain.

“These events would have been impossible without human-caused climate change,” said UN secretary-general Antonio Guterres.

In just the United States, there have been 18 weather or climate disasters this year, according to the National Oceanic and Atmospheric Administration. In the 1980s, the average year only saw three such disasters.

“We now have five times the number of recorded weather disasters than we had in 1970, and they are seven times more costly,” said Mr Guterres, speaking about global totals. “Even the most developed countries have become vulnerable.”
