Why are extreme weather frequent?

In the past 50 years, global warming is happening at an unprecedented rate since 2000. "Climate change has not only brought about an increase in the global average temperature, but also led to a trend of frequent, extensive, intense and concurrent extreme weather and climate events." Lv Bo, director of the Climate Change Impact Adaptation Office of the National Climate Center, said that taking extreme high temperature events as an example, the frequency of extreme high temperature is 4.8 times that before industrialization; At the same time, climate warming will also lead to the increase of water content in the atmosphere, and more water vapor will also increase the probability of extremely strong precipitation events.

Mitigation and adaptation are two major strategies to deal with climate change. In terms of policy system, multi-sectoral industries have issued action plans to adapt to climate change, and incorporated ideas and requirements to adapt to climate change into relevant policy documents such as meteorology, agriculture, water conservancy, ocean, urban and rural construction, and ecological environment protection. A number of key projects have brought benefits into play, the pilot construction of climate-adapted cities and sponge cities has been carried out steadily, and the ability of key areas to adapt to climate change has been effectively improved.

In terms of domestic governance, China has actively implemented the national strategy to deal with climate change, promoted the adjustment of industrial structure and the optimization of energy structure, and accelerated the construction of a "double carbon" policy system, which has achieved remarkable results in carbon emission reduction. Since the 18th National Congress of the Communist Party of China, China's energy consumption intensity has dropped by 26.2%, equivalent to about 6543.8+0.4 billion tons of standard coal consumption, and the carbon dioxide emission has been reduced by 2.94 billion tons.
