Back to the heating at the end of the day. the heating that is caused by fossil fuels has now warmed every region of the world and whether it s wild fires out west, which of course the heat is drying out soil layers, drying out vegetation, creating more fuel for those wild fires. we also see an increase noted in the report in dry, windy, hot conditions that is that fire prone weather that s referenced in the report. down here in the southeast, we re talking about, of course, year on year on year of headlines about hurricanes. it s not just ida. we have seen this every single year with record-topping hurricanes. the report calls out increase in category 4 and 5s in recent ze kads and notes these will as well get worse with warming. we saw hurricane ida s intensification over the warmest waters of gulf. that would be exhibit a in the strong role between ocean surface warming and tropical cyclone and hurricane strength. professor kim cobb, we appreciate you being with us.
It seems awkward to regard the plough until it just threats since they traditionally symbolize fertility and good times but contemporary food production has become so industrialized that it causes damage to soil layers deeper down as well. soil compaction is an increasing problem become more and more specialized which calls for more rationalize ation measures the machinery gets larger and heavier cultivation seasons become longer so we tell the land while it s wet for. these factors or course soil compaction yield gradually decreases says the soil is deprived of and to breathe or. this impacts the layers below ploughing depth which become almost like cement. it creates
Photosynthesis is a miracle of nature that extracts carbon and in conjunction with the degradation of organic matter creates humus the soil layer that is a prerequisite for all food production it s in the humus that we find most of the nutrients but it s also the humus the disappears in modern farming diversity and the number of organisms decrease and the self-sufficient entity falls apart. it seems awkward to regard the plough until it just threats since they traditionally symbolize fertility and good times but contemporary food production has become so industrialized that it causes damage to soil layers deeper down as well. mark. soil

Infrastructures. since subsidence was established in one thousand nine hundred eighty one in shanghai they ve measured a lot of elevation of two to three meters. allow me for you. to keep watch on this change the city built an extensive surveillance network. through the storm. this is our ground subsidence monitoring network for shanghai. it s made up of thirty seven land subsidence monitoring stations. we re here in one of the this is where we monitor the evolution of ground subsidence and the different layers at various steps. today the measurements are carried out fully automatic lay the real time monitoring of the different soil layers makes it possible to observe the variations of subsidence more than two hundred meters below
