Why extreme weather events get normal? A new study finds reasons

New Delhi: Extreme weather events are becoming normal across the world.

Obviously the rhythm to which the weather events occurred has gone wrong in many places.

In Kerala monsoon occurs quite differently from the past with rains falling belatedly but often extremely—this time threatening with floods.

Two major floods a couple of years before left the state in a bad shape. It has not yet overcome the damages caused.

More extreme weather events have been reported across the world from the wildfires in the US to heat-waves in Europe to flooding in China.

Now an analysis of over 400 peer-reviewed studies say most of these weather events are man-made.

Of course they are triggered by climate change which is actually precipitated by human activities.

UK based organization Climate Brief reviewed the papers, opening the possibility for debate on climate change.

According to it, 71 per cent of the 504 extreme weather events were man-made more likely or more severe by human-caused climate change.

The review also found that 93 per cent of all extreme heat events were speeded up by climate change.

Researchers have combined evidences from the past 20 years, tracking a total of 504 weather events since beginning of the year 2000.

Researchers found in 80 percent of case studies that human-caused climate change altered severity of an extreme weather event, according to a report.

The revealing study is important ahead of the climate summit to be held later this year in Egypt.
