Desert Aquifers Could Hold More Carbon Dioxide than All Earth’s Plants

Dr Yan Li and co-authors followed the journey of water through the Tarim Basin from the rivers at the edge of the valley to the desert aquifers under the basin. They found that as water moved through irrigated fields, the water gathered dissolved carbon and moved it deep underground. Image credit: Yan Li.

According to a new study published online in the journal Geophysical Research Letters, massive aquifers underneath deserts contain approximately one trillion tons of carbon, about a quarter more than the amount stored in plants on land. Dr Yan Li and co-authors followed the journey of water through the Tarim Basin from the rivers at the edge of the valley to the desert aquifers under the basin. They found that as water moved through irrigated fields,...

Thousands of supraglacial lakes form each spring and summer on top of the Greenland Ice Sheet. When they drain, they send torrents of water to the base of the ice sheet, lubricating the interface between rock and ice. That allows the ice sheet to flow faster to the ocean and discharge ice into ocean, which causes sea levels to rise faster. Image credit: Laura Stevens / Woods Hole Oceanographic Institution.
