Major rivers may be drying up, but in Pakistan they have the opposite problem – catastrophic floods from unstoppable rain: See this video for details: Ĭlimate Disaster #3 – A Gigantic Flood in Pakistan Now everyone who depends on these rivers is scrambling. In the United States it is the Colorado river and its big reservoirs. In Europe the Danube, Loire, Oder and Rhine rivers are affected. In China, the Yangtze River is drying up. Major cities that have depended on these rivers for hundreds of years lose these advantages due to droughts from climate change. One barge can easily carry the load of a hundred or more trucks. A river barge is an efficient and inexpensive way to move cargo between inland areas. And we can also use rivers for transportation. We can dam rivers to form reservoirs and generate power.

Rivers can be an important source of drinking water plus irrigation water, and they can also carry away waste water. Many of the world’s great cities therefore are located on rivers. Human beings have loved rivers for thousands of years. It’s not just the Colorado River drying up.The World’s Rivers, Canals and Reservoirs Are Turning to Dust.Climate Disaster #2 – Rivers Are Drying Up All Over the World And then the reduction in power generation from the drought can affect factories that many parts of the world depend on. Therefore, agricultural problems in a highly populated country like China make everything worse. The reason why these problems can have global effects is because the world is already facing grain shortages. It impacts agriculture, electricity production, drinking water, river navigation and so on. This combination of heat + dry can have multiple disastrous effects.
Therefore, the rivers and reservoirs are drying up.In conjunction with the high temperatures, the rain has stopped.Many cities are seeing summer temperatures above 100 degrees F during the day, some topping 110 degrees F in places that have never seen temperatures this high. Hundreds of cities and towns all over southern China have been reporting unprecedented record-high temperatures for weeks.In a nutshell, here is what has happened in China: These two things together have the potential to eventually affect the entire planet in one way or another because of China’s central role in the world economy. And then the temperatures have skyrocketed. It is a huge swath of land affecting millions and millions of fellow human beings. The problem is that it has stopped raining in Southern China. Extreme China heatwave could lead to global chaos and food shortages.Heatwave in China is the most severe ever recorded in the world.But if we dig a little deeper, it is possible to find buried headlines of a most urgent nature: China is on the other side of the planet, and it is a country that may not receive a lot of sympathy right now. You may not have even heard about the unfolding climate catastrophe that China is facing this year. For a lot of people, “out of sight, out of mind” can be a real thing.Ĭlimate Disaster #1 – The Unbelievable Heatwave in China In addition, the fact that these different events have been spread out all over the globe can obscure the total impact. I realize that most people do not have the time to keep up with every news item. In terms of catastrophic climate change events, August 2022 has been an incredibly newsworthy (and therefore deeply depressing) month for humanity. RALEIGH – “What is going on?!” is perhaps the best way to sum up the month of August 2022 on Planet Earth.
