1. How to solve the problem of Tuvalu, a sinking country of global warming?

First of all, we have to solve the problem of global warming. So how to deal with the crisis of global warming? Scientists think that cooling the earth first, how to cool it down? You can't put the earth in the refrigerator. In fact, scientists should "hold an umbrella" for the earth and reduce solar radiation to curb global warming.

For example, as early as the 20th century, the eruption of Mount Pinatubo in the Philippines sent a lot of aerosols and sulfur-containing compounds into the stratosphere, so after the eruption, the global temperature dropped by 0.56 degrees Celsius within one year, which gave scientists many hints. Researchers believe that it is not bad to use similar principles to cool the earth.

At present, some climatologists have started similar small-scale experiments. They use hot air balloons to spray foggy substances such as sulfur dioxide, alumina and calcium carbonate into the stratosphere of the atmosphere, and then use sensors to observe the reflectivity, dispersion or aggregation of these particles in the atmosphere to study their impact on the atmosphere.

However, there are still many questions in this study, such as whether this technology can achieve accurate control of global temperature? What substance is the most effective? And what side effects does this experiment have on the atmosphere and the environment? Researchers believe that it may take a long time to study and verify. However, they also said that this research should move forward, because if the experiment really works, it will certainly effectively alleviate the global warming crisis.

Of course, this is not the first time that scientists have conducted similar research. As early as 2009, Russian scientists used helicopters and cars to spray aerosol particles, trying to analyze how particles affect reflected sunlight. However, limited by the scientific research level at that time, there was no optimistic research result.

At present, it may still be far from solving the global warming crisis.
