A climate specialist has questioned the Ministry of Environment's plan to launch a "cool map" next month, saying that coping with rising city temperatures should highlight vegetation instead of air-conditioning.
The ministry's planned "cool map" would help people locate air-conditioned spaces in cities, but National Cheng Kung University professor Lin Tzu-ping (林子平) said that it should instead identify comfortable outdoors areas to alleviate the summer heat.

Air-conditioning can actually reduce people's resilience to heat, and therefore any anti-heat strategy should prioritize public areas and more vegetation, said Lin, who heads the university's Building and Climate Lab.
The most effective city cooling strategies usually incorporate a combination of plants, water and wind, Lin said, suggesting that Taiwan create more interconnected shaded areas with ventilation and water features for people to cool down.
In Singapore, for example, there are shaded areas within 400m of the subway stations, which protect people from the heat when they are outside, he said.
On the question of Taiwan's future urban cooling strategies, Lin said that greater cross-agency collaboration would be needed, with the Ministry of the Interior, for example, overseeing building policies, while local government agencies manage parks.
A magnitude 6.1 earthquake struck off the coast of Yilan County at 8:39pm tonight, the Central Weather Administration (CWA) said, with no immediate reports of damage or injuries. The epicenter was 38.7km east-northeast of Yilan County Hall at a focal depth of 98.3km, the CWA’s Seismological Center said. The quake’s maximum intensity, which gauges the actual physical effect of a seismic event, was a level 4 on Taiwan’s 7-tier intensity scale, the center said. That intensity level was recorded in Yilan County’s Nanao Township (南澳), Hsinchu County’s Guansi Township (關西), Nantou County’s Hehuanshan (合歡山) and Hualien County’s Yanliao (鹽寮). An intensity of 3 was
Instead of focusing solely on the threat of a full-scale military invasion, the US and its allies must prepare for a potential Chinese “quarantine” of Taiwan enforced through customs inspections, Stanford University Hoover fellow Eyck Freymann said in a Foreign Affairs article published on Wednesday. China could use various “gray zone” tactics in “reconfiguring the regional and ultimately the global economic order without a war,” said Freymann, who is also a nonresident research fellow at the US Naval War College. China might seize control of Taiwan’s links to the outside world by requiring all flights and ships entering or leaving Taiwan
The next minimum wage hike is expected to exceed NT$30,000, President William Lai (賴清德) said yesterday during an award ceremony honoring “model workers,” including migrant workers, at the Presidential Office ahead of Workers’ Day today. Lai said he wished to thank the awardees on behalf of the nation and extend his most sincere respect for their hard work, on which Taiwan’s prosperity has been built. Lai specifically thanked 10 migrant workers selected for the award, saying that although they left their home countries to further their own goals, their efforts have benefited Taiwan as well. The nation’s industrial sector and small businesses lay
Quarantine awareness posters at Taiwan Taoyuan International Airport have gone viral for their use of wordplay. Issued by the airport branch of the Animal and Plant Health Inspection Agency, the posters feature sniffer dogs making a range of facial expressions, paired with advisory messages built around homophones. “We update the messages for holidays and campaign needs, periodically refreshing materials to attract people’s attention,” quarantine officials said. “The aim is to use the dogs’ appeal to draw focus to quarantine regulations.” A Japanese traveler visiting Taiwan has posted a photo on X of a poster showing a quarantine dog with a
