In the face of the extreme weather brought about by climate change, it is difficult for Hong Kong to be alone. After last year becoming the warmest year on record, the average temperature this year is also expected to be higher. The director of the Hong Kong Observatory, Zheng Chuming, warned that if the temperature increase continues, the temperature in Hong Kong will be the highest or reach 40 degrees Celsius decades later, "that is, it will be easy to see 40 degrees or more in the future. ".

Many people still remember the scene of the super strong typhoon "Mangosteen" in 2018. Zheng Chuming pointed out that under climate change, there will be more rainfall; and the typhoon wind will be stronger, "The wind can be strong, anytime To the super typhoon. " He hopes that the people of Hong Kong can work together to reduce carbon emissions. "Everyone has to do it, and the accumulation of less will become more, so that we can do the worst way."

Global warming or far beyond the limits of the Paris Agreement

This year Mother's Day temperature reached a new high of more than half a century, the weather is hot and unbearable, but the temperature may rise sharply in the future. Zheng Chuming, who took over as Taiwan ’s director in mid-February, said in an interview with "Hong Kong 01" that some people think that climate change is just "frightening", but he seriously emphasized that "it is not scary, the actual system is tight" and agrees The situation is like "a boiled frog in warm water", which changes and accumulates all the way, but the effect is only discovered after a long time.

The "Paris Agreement" hopes to limit the global temperature rise to within 1.5 degrees before the Industrial Revolution. Zheng Chuming bluntly stated that the current temperature rise has reached 1.2 degrees. "There is very little left, and the trend will rise in 10 years and 20 years. 1.5 degrees) ". The increase of less than two degrees seems to be slight, but Zheng warns that if he "do it again", it will heat up to three to six degrees by the end of this century. "The highest temperature in Hong Kong is 36.6 degrees in 2017, simply add that it has been exposed to 40 degrees. This situation will be even more frequent. "

In the face of the rain, it may fall heavily, and it is undecided to have heavy rain at any time; second, if there is a typhoon, the wind can be strong, and it can go to a strong typhoon at any time. The impact of the burial is great, and it is a challenge to all meteorological units. Big. Everyone can contribute to reducing emissions? Relieve the trend and do not take the worst path.

Rainfall under climate change fears more typhoons and stronger winds

The scene of typhoon collapsed with trees, rubble, flooding and waists was shocking. Zheng Chuming believes that in addition to bringing challenges to global meteorological units, climate change will also face more rainfall and stronger typhoons, and worries will greatly affect people's livelihood. He explained that as the air temperature rises, the stored water vapor also increases, turning into a tropical cyclone to bring more energy. "In the face of the rain system, it may fall heavily, and there may be heavy rain at any time; if the second system has a typhoon, it can be It ’s so good, you can always go to a super typhoon. "

As for the outlook for this year's weather, Zheng maintained early this year that Hong Kong will enter the windy season in June or later, and about four to seven tropical cyclones will enter the 500-kilometer range of Hong Kong throughout the year, with less rainfall.

The office does not turn off the lights and air conditioner Zheng Chuming: Hong Kong citizens must work together to reduce emissions

Stepping into Zheng Chuming's office, even if he works at home, he rarely turns on the lights, or thinks he is not inside; there is a floor fan next to the desk. Unlike other government officials who saw suits in full suits, Zheng only wore short-sleeved shirts and did not even tie his tie during his visit. He laughed and said, "It will be cool, the air conditioner will not turn on, and the fan is already cool enough!" He also explained that the lights were not turned on because there was a large glass window behind the desk. "Natural light is enough. I tried not to turn on the lights at 6 or 7 at night."

Former Observatory Director Lin Chaoying and Secretary of the Environment Huang Jinxing and others often "fight for less electricity", Zheng Chuming smiled and said, "It's hard to fight with the channel, it's too larat", but he emphasized that emission reduction requires the efforts of all Hong Kong citizens to mitigate the climate Change, "I want everyone to do it together, and use less water, so you can save as much as you can."

Under the epidemic, carbon emissions are reduced Zheng Chuming: don't think it will be better in a short time (climate change)

Under the new coronavirus pneumonia epidemic, most of the economic activities will be suspended, and the number of aircraft flights will also be greatly reduced. Although carbon emissions are reduced, Zheng Chuming believes that it has little effect on the overall climate change. "Climate change is a long-term trend, but it fell and fell, and all recovered after the epidemic. Do not think that humans will stop activities for a short time (climate change) It will be good ".

In addition, the public service of the Observatory was also affected by the epidemic. Zheng Chuming said that the opening day originally held in March had more than 10,000 people participated in it in the past, and this year it will be cancelled due to the epidemic. In addition, the international conference will also be held online. As for when can return to normal? Zheng pointed out that "it is better to wait for the situation first" and emphasized that forecasting and other services will not be affected.
