Due to climate change, the sex ratio of newborn sea turtles in Florida coast of the United States is unbalanced. In recent years, the sex of newborn turtles is basically female, and male turtles are rarely seen. All this is caused by extreme weather-high temperature. Because turtles have a characteristic, that is, the sex of the hatched turtles is greatly affected by the environmental temperature. If the ambient temperature is below 28 degrees Celsius, more males will hatch. If the ambient temperature is higher than 3 1 degree Celsius, the situation is just the opposite, and the hatched turtles will be mostly females. With the increase of earth temperature in recent years, there will be more and more females in the turtle population. In this way, the normal reproduction of turtles will be seriously affected, and the number of turtles will become less and less!

Why are there more and more extreme weather on the earth now? In many places, the temperature often exceeds 40 degrees Celsius, and the earth has become a big steamer, which makes people feel flustered. The continuous high temperature is actually the chief culprit of extreme weather. As a result of this climate change, many places have experienced floods, six In the snow and so on. Global warming will also lead to melting glaciers, rising sea levels, flooding coastal areas and causing great losses to human production and life.

These are not all. Imagine if the temperature gets higher, will it make the water vapor evaporate, and the rainstorm weather caused by it will also increase; If it is too hot, the land will be dry, crops will be reduced and food will be insufficient. This is another big problem. The unstable climate will also make infectious diseases and epidemics spread more easily and increase the burden of medical and health undertakings.

All these remind us that extreme weather on the earth is frequent, which is related to temperature changes and environmental changes on the earth. Protecting the environment is an important task that requires a lot of time, money and energy. Everyone must cheer up, persevere and persevere. We should actively respond to climate change and be ready to deal with frequent extreme weather.
