SYDNEY, Nov 23 (Reuters) - Australia's climate conditions will worsen in the years ahead, two national agencies said on Wednesday, warning of quicker changes in weather patterns and more frequent extreme climate events. Australia has been enduring extreme weather events that some experts attribute to climate change. Heavy rainfall events are becoming more intense and more frequent short-duration heavy rainfalls are also expected, the report showed. "This trend is expected to continue into the future," CSIRO Director of Climate Science Centre Jaci Brown said. "We're seeing mass coral bleaching events more often, and this year, for the first time, we've seen a mass coral bleaching on the Great Barrier Reef during a La Nina year."
