Do you know what dangers the extreme high temperature weather in Antarctica and Arctic will bring to human beings?

Recently, many people are paying attention to COVID-19 and the Russian-Ukrainian war, but there is an incident that concerns the health of all of us, but it has been buried. I don't know if you have noticed. Scientists have found that extreme hot weather has recently appeared in the Antarctic and Arctic. The temperature in Antarctica is nearly 40 degrees higher than the average temperature in the same period in history, while that in the North Pole is nearly 30 degrees higher. What are the concepts of 30 degrees and 40 degrees? As we all know, there are many glaciers in the Antarctic and Arctic, and the formation and maintenance of glaciers require cold temperatures. If the temperature continues to rise, polar high temperature will become more and more common, which will have a great impact on the global climate. It is possible that the iceberg will melt, the sea level will rise and part of the land will disappear, then the original ecological balance will be destroyed and many problems will be brought.

First question: There are many bacteria and viruses in the glaciers and permafrost of the North and South Poles. Then in the summer of 20 16, reindeer and herders in Siberia contracted a mysterious disease. After research, it was found that they were infected with anthrax, and this pathogen has not appeared in the local area for many years. Finally found in 194 1 There was an anthrax epidemic in the local area, which caused many reindeer to die. Now, scientists have returned to reindeer that have been dead for more than 70 years and found this pathogen. Scientists believe that climate warming has caused the thawing of the frozen soil, and the pathogens that have disappeared for many years have returned.

The second question: In the Arctic where polar bears live, they need to rely on ice floes when looking for food in summer. Ice floes can help them find their prey. However, the continuous high temperature will reduce the floating ice, which will make it difficult for polar bears to find food and even have to go to places where people gather to find food. In addition, there are penguins in Antarctica. The rapid melting of sea ice will lead to the premature launching of chicks, and the launching of chicks before they put on waterproof feathers will increase their mortality.

The third question: Some studies show that there are still many green turtles in the ocean who die because of eating plastic by mistake. What about the sperm whale found after salvaging it? There are dozens of kilograms of plastic waste in his stomach, so the natural degradation of plastic products takes decades or even hundreds of years. Then we throw away the masks used to fight the epidemic, the plastic bags we bought before, the plastic lunch boxes and mineral water bottles after eating and drinking. We humans and animals and plants live on the same earth. When the climate changes suddenly, the ecological balance is broken, and the survival of animals is threatened, one by one, who will be extinct next?
