Let's talk extensively about the signs of global warming.

With the increase of global greenhouse gases, the absorption of ground radiation will increase, and the atmospheric temperature will also rise. The high temperature weather on the earth causes the sea level to rise. If the beach is flooded, people will lose a lot of fun.

The glacier has melted.

When the ice and snow in the North and South poles melt and the sea level rises, some islands will be submerged. Due to the rising surface temperature, Montana's National Glacier Park has lost many magnificent scenery.

3. The heat wave is coming

Heat wave will not only inhibit some functions of human body, but also cause death. In the last 50 years to 100, the frequency of extremely hot heat waves is two to four times higher than usual. It is predicted that it will be higher than 100 times in the next 40 years. Experts predict that the continuous heat wave will lead to an increase in the frequency of fires and related diseases and an increase in the average temperature of the earth.

Storms and floods have increased.

The snow line rises in mountainous areas, the melting speed of frozen glaciers accelerates, and the recharge to surface rivers increases, which is easy to cause floods. No one really wants to see more and more super-large storms: in just 30 years, the frequency of strong hurricanes of magnitude 4 to 5 has almost doubled. Warm sea water increases the possibility of strong storms.

5. The drought cycle is long

With the climate warming, experts estimate that the drought may increase by at least 66%, which will lead to the shrinking of water supply and the decline of crop production quality. This puts global food production and supply in danger, and people are increasingly at risk of being threatened by hunger. The worldwide drought exposed the shortage of food in rural areas.

6. The types of diseases have increased.

With the hot weather of floods and droughts, viruses have created an excellent growth environment, and mosquitoes, ticks, mice and other organisms carrying diseases are becoming more and more prosperous.

7. Economic problems have increased.

As the temperature rises, the cost of making up for the losses caused by climate change is increasing. Severe storms and floods have caused billions of dollars in agricultural losses, and at the same time, a lot of money is needed to treat infectious diseases and prevent the spread of diseases. Extreme weather will also cause an extremely serious economic downturn.

8. Conflict and war

The reduction of high-quality food, water and land will increase the hidden dangers threatening global security, which will lead to conflicts and wars.

Countries lacking in water resources and food have thus laid a security risk, and regional turmoil, panic and aggression may occur.

9. Loss of biodiversity

Global temperature rise is more and more harmful to the survival of species. If the annual average temperature keeps rising at the rate of 1. 1 to 6.4 degrees Celsius, about 30% of the existing plants and animals will face the threat of extinction by 2050. These species will be extinct due to desertification, deforestation, ocean warming and inability to adapt to the climate. Wildlife researchers have noticed more flexible migration. Animals migrate from the far north to the far south, looking for their habitat. For example, the red fox, once a resident of North America, now lives in the Arctic. The habitat of red fox has been affected by global warming temperature.

Humans are not immune. Desertification and sea level rise threaten human habitat. When plants and animals lose their ability to adapt to climate change, there will be no food, fuel and income for human beings.

The ecosystem is destroyed.

Climate change and the increase of carbon dioxide are tests on human ecosystem, which threaten fresh water, clean air, fuel and energy, food, medicine and other impacts on human survival.
