SINGAPORE - Catch up with the hottest topics on The Straits Times' new weekday talk show.

The Big Story, broadcast every weekday at 5.30pm on Facebook and YouTube, has reporters and senior editors discussing the top stories of the day, in the heart of the newsroom.

On Tuesday's (Sept 24) episode, climate change editor David Fogarty and environment correspondent Audrey Tan will talk about the Climate Action Summit, which took place at the United Nations headquarters in New York on Monday.

They will also discuss Singapore's first climate rally.

They will be followed by senior correspondent Tan Ee Lyn, who will expand on an ST analysis that found food poisoning is more likely to occur from dining at restaurants and consuming catered food than from eating at foodcourts and coffee shops.

Topics covered in previous episodes include how a phenomenon known as the Indian Ocean Dipole is likely causing the dry spell in Singapore; new government measures to encourage parenthood and marriage; the instances where people have to give their NRIC details under stricter rules from Sept 1; and how the growing presence of virtual restaurants and ghost kitchens by food delivery apps disrupt the food and beverage scene here.
