Humanity’s need to tackle climate change is more pressing than ever, with the United Nations warning last week that global warming would accelerate at a faster-than-expected pace over the next 20 years. In this four-part series, the Post examines its impact on the city, how the Hong Kong government can best play catch-up, and who is walking the talk in the private sector. Part one looks at how human activity is leading to extreme weather patterns, leaving the world vulnerable to floods, forest fires and typhoons.

The Taklamakan Desert in China’s western Xinjiang province is one of the driest places in the country, where only 1cm (0.4 inches) of rain falls every year.

But in mid-July, floods caused by melting glaciers in the Tian Shan mountains filled a 300 sq km area of the desert, including an oil exploration site of China Petrochemical Corporation (Sinopec Group).

The flood created a lake that inundated nearly 30,000 items of heavy equipment and 50 exploration vehicles, according to Sinopec Group’s video clips posted on China’s social media networks. There was no loss of life, the group’s spokesman said.

The sudden flood in the desert was hardly isolated as far as freak weather incidents go, not only in China, but globally.

This year alone, the world has already witnessed episode after episode of extreme weather events, offering more evidence of climate change and warning political leaders, businesses and individuals that they must act fast to cut back on carbon emissions.
