    Record-breaking rainstorms / Space economy development

    主持人:Rainbow Leung and John Bruce

    On Wednesday's Backchat, we looked at why there's been extreme rainfall in the past few days. The Observatory had issued the Black Rainstorm Warning four times in eight days, the most it has ever set within a year. The forecaster also said precipitation seen at its Tsim Sha Tsui headquarters broke the daily rainfall record for August, since record keeping began in 1884.
    In Beijing, authorities upgraded their rainstorm alert to the highest level on Monday. A day prior, flooding was recorded in Gansu and Qinghai. We talked to climate scientists to learn more about what's behind these adverse weather events.
    After the break, we looked at the opportunities Hong Kong can seize in the space economy. The Federation of Hong Kong Industries has urged the government to promptly formulate space economy policies, after jointly publishing a report with the City University of Hong Kong.

    9:05am-9:40am: Record-breaking rainstorms
    Speakers:
    Amos Tai, Associate Professor and Director of the Earth System Science Programme, The Chinese University of Hong Kong

    9:40am-10:00am: Space economy development
    Speakers:
    Duncan Chiu, Lawmaker (Technology and Innovation)
