What are the consequences of global warming?

Examples of disasters brought by climate to mankind are as follows:

1. Global warming will lead to slow marine disasters.

Global warming will cause seawater expansion, ocean warming, sea level rise and glacier melting. When the global temperature rises 1℃ ~ 2℃, the probability of extreme high temperature weather will also increase. El Nino is an abnormal climate phenomenon caused by the abnormal rise of water temperature in the equatorial waters of the Pacific Ocean, which will cause climate anomalies in many areas around the Pacific Ocean, such as frequent rainstorms and floods in some areas; In other areas, there is high temperature and little rain, and the drought is serious.

2. Global warming will affect agricultural output.

Climate warming will easily lead to natural disasters such as floods and droughts, which will increase the instability of agricultural output. As the temperature rises, the growth cycle of different crops (such as crops with two crops or three crops a year) changes, and the agricultural layout and structure change. At the same time, global warming will increase the evaporation of crops, and will also greatly increase the irrigation cost, pesticide consumption and chemical fertilizer consumption of agriculture.

3. Global warming will increase the calm weather in North China Plain, and severe smog events will occur frequently in winter.

A study jointly conducted by scientists from China and Australia shows that the increase of greenhouse gases in the atmosphere will make the land heat up faster in winter, and the temperature gradient between the land and the ocean will also decrease, which will lead to the lack of northwest wind in the North China Plain. In addition, there is little rainfall and snowfall in winter in North China Plain, which will not disperse the deposited smog, thus increasing the frequency and duration of severe smog events in winter.

4. Global warming will change the ecosystem of species interaction and affect species diversity.

For example, according to the reference news network, a study using lizards found that when the intestinal flora in lizards lives in an environment where the temperature is 2℃ higher than the normal level, the number of bacteria will decrease by 34%. Climate change not only affects the diversity of intestinal flora of lizards, but also affects their life span. Lizards affected by climate change live shorter lives than lizards not affected by climate change.
