Scientists predict that 2050 or extreme weather will come to an end after 30 years?

The future under climate change may seem very vague and changeable, and climatologists have given the prospect forecast of the earth in 2050.

You know, since 1979 was recorded, the extent of Arctic summer sea ice has dropped by about 40%. Since the early 1990s, the sea level has risen by about 3/32 inches every year. In the past 30 years, the temperature of the earth's surface has been higher than in any decade since 1850. Therefore, we have to admit that human beings are the "leading factor" of global temperature rise in the past century. Although we often talk about the uncertainty of future climate prediction, there are some things we can be sure of, that is, the earth will continue to warm.

We also know that as the temperature rises, the adverse effects of climate change will be disproportionately amplified, and the risk of irreversible catastrophic changes will also increase. We also know that due to the accumulation of carbon in the atmosphere, no matter what the future carbon emission trend is, it will definitely cause a certain degree of climate change. This means that no matter what we do, it is very necessary to adapt to possible climate change. Of course, we also need to plan how to protect our lives from climate change and protect the natural environment as much as possible.

However, the more information we know, the more uneasy we feel, because it may be more challenging than we thought before. Judging from the timetable of climate change, 2050 is not far away. We can describe the climate of the future world to some extent. Here, I won't list the facts and figures related to climate in detail, but I can try to outline what our world might look like if we can't significantly reduce carbon emissions. For example, we all know that the poorest countries and regions in the world will feel the worst impact of climate change, because they are already under great pressure to survive, and the impact of climate change is the last straw to crush their camels.

Now let's fast-forward to 2050, when the surface temperature of the earth will be 2 degrees Celsius (3.6 degrees Fahrenheit) higher than that of a century ago, and the global sea level will rise by 1 foot. There is no ice in the Arctic in summer now, and the ocean temperature has greatly increased. The number of marine mammals, fish and birds is changing, and people in poor countries will be fatally threatened by food shortage; The disappearance of coastal sea ice, rising sea level and increasing sunshine intensity are forcing people to be displaced in some places. The potential species invasion caused by the increase of human activities is changing the whole natural ecosystem.

In India, the high temperature before the monsoon is having a serious impact on most areas, especially the whole northern plain. With the increase of daily rainfall intensity, the flood in rainy season becomes more and more serious. With the rise of sea level, people living in low-lying coastal areas are experiencing more and more frequent seawater intrusion. Fresh water supply is polluted, farmland is destroyed, and forced migration is put on the agenda. Kiribati and other small island countries in the central Pacific Ocean are no longer suitable for living because of rising sea levels.

In some other countries, coral bleaching has caused people to lose sustainable fisheries, which depends on people's food security. Southern Australia and the Mediterranean will be in a state of long-term drought, and wildfires will become more and more dangerous, threatening various family and urban environments and destroying natural ecosystems. With the depletion of aquifers, the problem of water security is becoming more and more prominent. In America, the weather is changeable, and the temperature and rainfall are becoming more and more extreme. Heat waves are becoming more and more common in summer.
