The discussion centers on the mysterious craters found in Siberia, particularly one on the Yamal peninsula, which may be caused by an underground gas explosion linked to nearby oil and gas fields. Participants suggest that the craters are not merely collapses but involve ejecta, indicating a more complex geological process. A numerical model presented predicts that the methane concentration at the crater's base is 9.6%, correlating with a surface air temperature of approximately 54°F. The ongoing convection of methane-laden air is theorized to enhance crater growth by facilitating rapid heat transfer.
PREREQUISITESGeologists, environmental scientists, climate researchers, and anyone interested in the dynamics of methane release and its implications for climate change.
I suspect you are mistaking the thousands of permafrost melt ponds that occur all across the north for those newly formed craters. For a striking example of the thousands of lakes in the far north, see this map https://www.google.com/maps/place/69°36'00.0"N+132°00'00.0"W/@69.6,-132,8z/ of the Tuktoyaktuk Peninsula, in the Canadian Northwest Territories.Bystander said:Just browsed the Yamal on Google Earth --- "dozens?" --- there are thousands --- not all recent, certainly.
