How does climate change affect the likelihood of extreme rain? Federal department aims to publish rapid results

Federal scientists will start to publish rapid results looking at how much more likely major rainstorms have become due to climate change.

Environment and Climate Change Canada says it's expanding its rapid attribution system, so far used to analyze extreme temperatures, to also include extreme precipitation.

"This area of research supports important decision-making that helps Canadian communities prepare for and adapt for the changing frequency and severity of extreme weather events," said Madalina Surcel, a climate extreme specialist with the department.

Officials say they have already run the tool on 42 extreme precipitation events across Canada since June. They say the vast majority of those events were up to two times more likely to happen because of climate change, and three were
