World Animal Day on animal hazards caused by climate warming

China Meteorological News Today (October 4) is the World Animal Day. Animals are human's good friends, together with mankind to maintain the ecological balance of the Earth. The impact of global warming on humans also affects animals on earth. Climate warming has led to the loss of rules for animal evolution, the decline of many bird populations, the cessation of coral growth, the migration of certain organisms, the extinction of some animals and the expansion of some species. Studies have shown that some animals have changed their way of life and adapted to the effects of climate change, especially in smaller terrestrial animals, which has become a reference for us to protect animals.

Damage caused by climate warming to animals
1. Animal evolution loses its rules
The conventional wisdom is that evolution is a slow-growing process that takes several generations. However, new research suggests that the rapid evolution of plant and animal species in the face of a rapidly changing environment is mainly due to climate change. Climate change accelerates the evolution of reptiles, and some animals evolve in different shapes to adapt to climate change.
2. Some animals become larger
Scientists have found that current global warming trends may have an impact on animal size. Researchers in California have found that birds in the vicinity of the San Francisco Bay and Cape Verde National Marine Park have grown more slowly over the past 40-27 years. The finding suggests that some animals are coping with climate change in a way that is larger in size.
3. Some animals become smaller
Recently, more and more studies show that polar bears, squirrels, frogs, fruit flies and other animals are smaller. The results of the survey show that many animals in the world no longer need to store too much calories to live, so they become negative in their intake of food and nutrition and have less physical fitness than before. By this effect, the growth and development of animals will be slowed down, and the head will grow smaller.
4. Loss of certain functions of animals
Researchers found that the higher the carbon dioxide in the air, the more the seawater absorbs carbon dioxide and the stronger the acid. This has led to the loss of hearing by clown fish perched on coral reefs and rocks. This means that the ability of the Clown fish to monitor the sound of predators is reduced and survival is threatened. In addition to avoiding predators, sound in the search for companions, collective hunting, foraging also plays an important role, if the clown fish lose all these abilities, the consequences of unimaginable.
5. The extinction of birds
Recent studies have stumbled on a worrying trend: as the average temperature rises, many bird populations fall. According to a study by researchers at Utah State State University in the United States, temperatures up 3.5 degrees Celsius could lead to the extinction of 600 to 900 species of birds.

6. Biodiversity reduction
Corals known as the "Rainforest in the ocean" are highly susceptible to rising sea temperatures. The researchers predict that if carbon emissions continue to grow, many corals will stop growing, and the damage they suffer will hamper their chances of recovery and have a profound impact on other organisms in the ecosystem, as the disappearance of corals has deprived many species of marine life of food and shelter. The reduction of biodiversity leads to more fragile and unstable ecosystems.
The representative animals affected by climate warming:

Polar bear: Polar bears face extinction as the Arctic ice melts rapidly, breeding and habitat disappears.

Penguins: Warming causes sea levels to rise, and the few lowlands in Antarctica will be submerged by seawater. The land has always been a breeding ground for penguins, which is a catastrophe for penguins.
Bicknell: A species of birds that breed and nest in higher-altitude mountains in northeastern North America. A slight rise in temperature can put the bird's breeding habitat at risk.
Flamingo: Living in a humid place in the Caribbean, South America, Asia and Africa. Climate change poses a threat to the availability and quality of their living environment.
Irrawaddy R. Dolphin: Living in Bangladesh and other parts of Southeast Asia, depending on the freshwater of the estuary. Changes in fresh water temperature and salinity may have an impact on the long-term survival of dolphins.
Musk Ox: An animal living in a harsh environment of Arctic tundra. It faces the big grizzly bear's prey, as more and more grizzly bears migrate northward into the musk ox territory.
Tortoise Turtle: ocean-going reptiles with temperature dependence. Higher temperatures can cause more females to hatch, which can unbalance their sex ratios and thus affect their lifespan.
Climate warming animals with mixed worries
Studies have shown that some animals have changed their way of life and adapted to the effects of climate change, especially in smaller, terrestrial animals. The climate warms the mice, and the increase in the concentration of carbon dioxide increases the individual intake of aphids.
The increase of precipitation can benefit the growth of rodent population by improving vegetation. Studies have shown that the increase in rainfall has enriched plants in the arid inner Mongolia, increased rodent food and increased the population density of gerbils. Aphids are the only type of insect that increases the response to increased carbon dioxide concentrations in the population. With the increase of carbon dioxide concentration, aphid individual intake increased. At the same time, the increase of carbon dioxide concentration also reduces the response of aphids to the alarm pheromone and reduces the predator-prey effect of natural enemy insects. The occurrence and harm of aphids will be more serious in the future.

How to protect animals from climate warming
1. Seek new protection programmes for animal protection.
2. The wildlife corridor helps to migrate.
3. Strengthening global cooperation in animal protection.
