00:00Human activity responsible for climate change has led to more than 50 heatwaves since the year 2000, researchers say.
00:09According to a new study published in the journal Nature, just over a quarter of all heatwaves in the last 25 years
00:17would have been virtually impossible without human-caused climate change.
00:22So we looked at the range of heatwaves that happened recently and we looked at how much more probable they were made
00:30because of those emissions of the carbon majors.
00:35And what we find is that for many events they were made clearly much more probable.
00:4255 of the 213 heatwaves were 10,000 times more likely to occur.
00:49The scientists also found that emissions from 180 major cement, oil and gas producers contributed significantly to all the heatwaves.
01:02We find that even individual contributions are often sufficient to make some of those heatwaves basically definitely much more probable.
01:12The polluters identified include publicly traded and state-owned companies,
01:17as well as a few countries where fossil fuel production data was available at the national level.
01:25The findings could have ramifications for lawsuits brought against major polluters,
01:30undercutting the argument that no single contributor can be considered responsible for the effects of pollution.
01:37The webinars are available at the national level andấm.
