Compared with global warming, what will happen to the world if it gets cold?

In fact, this result is not much different. Global warming will lead to cold climate, because the melting or sublimation of ice will absorb heat, so global warming will increase the temperature and accelerate the melting of glaciers and icebergs on the earth. The melting of glaciers and icebergs needs to take away a lot of heat, and then through the transfer and diffusion of heat, the climate outside icebergs and icebergs will be quenched.

Because people burn fossil fuels, such as oil and coal. Or cutting down and burning down forests will produce a lot of carbon dioxide, that is, greenhouse gases, which have a strong permeability to visible light emitted by the sun, a strong absorption to long-wave radiation emitted by the earth, and a strong absorption of infrared radiation from the ground, leading to an increase in the temperature of the earth, that is, the greenhouse effect. Global warming will redistribute global precipitation, melt glaciers and frozen soil and raise sea level, which will not only endanger the balance of natural ecosystems, but also affect human health and even threaten human survival.

The impact of global cooling: the speed at which the earth radiates heat into space is limited. The heat dissipation rate will slow down with the decrease of the average temperature and is limited by the greenhouse gases emitted by human civilization. Global cooling will give people plenty of time and reasons to adjust the earth's climate, such as spreading cinders on polar regions and glaciers to reduce reflectivity and absorbing the heat of sunlight to melt excess ice. Generally speaking, human beings don't need to maintain the current temperature, and the average temperature is about 1 Celsius. A large number of energy-saving and emission-reduction plans previously formulated by many countries in the world will need to be re-formulated. Many countries will increase the energy supply ratio of fossil fuels and biomass energy. House prices of climate shelters near the Great Lakes in North America will plummet.
