One study found that extreme flooding is not only caused by climate change.
Researchers at the University of Exeter have found that over the past 8,000 years, floods have surpassed the extremes in recent decades. [emphasis, links added]
Recent floods, such as Valencia last winter, Valencia, Spain and the UK as a whole, are linked to climate change and are accompanied by warnings “unprecedented.”
But Professor Stephen Harrison from the College's School of Life and Environmental Sciences said The new study found that many previous floods have surpassed recent extremes.
By dating and analyzing its scale with individual sand grains in floodplain sediments, researchers were able to assess the frequency and scale of flooding over thousands of years.
“In recent years, floods around the world, including Pakistan, Spain and Germany, have killed thousands of people and caused great damage,” Professor Harrison said.
“The flood like this is seen as ‘unprecedented’ – but if you look back over the past few thousand years, that’s not the case. In fact, we call floods an unprecedented flood may be far less than the most extreme that has happened in the past. ”
Research [published in the journal Climatic Change] The ancient circulation records of the Lower Rhine in Germany and the Netherlands, the Upper Severn in the United Kingdom and the Lower Rhine in the rivers around Valencia were examined.
In the Rhine, records from the last 8,000 years show that at least 12 floods may exceed modern peaks.
SEVEN analysis shows that floods have not been excellent in the monitoring of the past 72 years compared to the record.
The largest flood in the upper part of Sevon occurred around 250 BC and is estimated to be 50% higher than the 2000 flood during its peak period. This damaged 10,000 homes and led to new flood control.
Professor Harrison said climate change modeling can only trace back 120 years ago in records that floods may rely on, and natural variability can only be seen on a longer timeline.
“This is indeed the first time anyone has flooded past floods,” he said.
“Compared with the narratives that some climate attribution experts say, they say the floods we are suffering now are so great that they can only be caused by climate change caused by humans.
“These recent floods are huge, but not as huge as some things in the past.”
He added: “A few years ago, we clearly said that the climate modeling community was getting it wrong.”
