Climate change is irreversible Lin Chaoying warns of human food shortage

The Intergovernmental Panel on Climate Change (IPCC) led by the United Nations recently issued a report, issuing a "red warning" to mankind, saying that climate change is inevitable and irreversible.

Former Director of the Observatory, Lin Chaoying, stated on a radio program this morning (12th) that climate warming will affect the survival of fish and other animals, which will lead to instability of human food supply, and natural bacteria will also harm the human body.

Lin pointed out that even if the temperature of the earth is controlled, the heat that has entered the ocean cannot be resolved. The ocean will continue to "heat up" for hundreds to thousands of years. An irreversible fact has already occurred. He warned, "If we do not reduce emissions as soon as possible, the situation in the future It will be more serious, and extreme weather will last for decades."

The IPCC announced on August 9 "Climate Change 2021: Natural Science Basis-IPCC Sixth Assessment Report-Working Group 1 Report", stating that climate change is inevitable and irreversible, and the window for people to avoid catastrophic results has been In Shun Shun, UN Secretary-General Guterres called the report a "red warning" to mankind.

Lin Chaoying said on a radio program today that climate change has warmed the sea, threatening the survival of fish and animals that adapt to cold climates. At the same time, carbon dioxide has caused the sea to become acidic, affecting the number of plankton, and fish losing food.

"A fish is so smoggy, so I won't get used to it. Don't you think it's just heat and rain. It has a lot of chain reactions."

Lin also pointed out that according to biologists' research, when the temperature rises by 2 degrees from before the industrial revolution, the ecosystem will be severely affected.

At that time, the food supply will be unstable, and the bacteria in nature will also harm the human body.

"There may be less food, and there may be more diseases."

At that time, the food supply will be unstable and bacteria will invade the human body. There may be less food and more diseases.

Lin further explained that after the critical point of 2 degrees, human society will not be able to cope with changes in climate change. For example, ice in the Arctic Ocean can reflect sunlight. When the ice is melted, the sea water directly absorbs the sun’s heat. The vicious cycle makes the earth more serious. hot.

The sea will continue to be heated for hundreds to thousands of years, irreversible events have occurred

"A lot of things in Yijia are irreversible, but many people think that carbon reduction can be solved." Lin Chaoying pointed out that even if the temperature can be controlled, the heat that has entered the sea cannot be solved, saying that it will continue to heat for hundreds to thousands of years. An irreversible state of affairs is already happening.

Lin also pointed out that at present, we can only hope that the situation will not worsen. He believes that mankind needs to coexist with climate change for hundreds of years, and that only by controlling it can we work hard to deal with it.

He even warned that if we do not reduce emissions as soon as possible, the situation will become more serious in the future. "Extreme weather will last for decades."

Lin Xuhui pointed out that climate change will also affect Hong Kong. For example, the number of hot nights has risen from a few days ago to about 50 days in recent years.

Although the amount of rainfall may increase, he also estimates that until the middle of this century, Hong Kong will experience rare conditions from time to time.

"At the beginning of this year, it was rare to compare with 1963. At that time, water was supplied once on the 4th, and the water supply was once for 4 hours."

The Hong Kong government should consider investing in power generation facilities in the Mainland before sending electricity back to Hong Kong

As for the government's goal of achieving zero emissions by 2050, the next step is to consider replacing natural gas power generation.

Lin believes that the area of ​​Hong Kong is too small. He suggested that the government communicate with relevant mainland authorities to ship the electricity back to Hong Kong after investing in power generation in the mainland. He also urged the government to consider it as soon as possible.

El Niño and global warming are double-impacted by the Observatory. It is expected that the temperature will be higher and less rain this fall. [Global Warming] Sea level rise will worsen.
