Temperature dependence of basalt weathering

Gaojun Li, Jens Hartmann, Louis A.Derry, A.Joshua West, Chen-Feng You, Xiaoyong Long, Tao Zhan, Laifeng Li, Gen Li, Wenhong Qiu, Tao Li, Lianwen Liu, Yang Chen, Junfeng Ji, Liang Zhao, Jun Chen Abstract The homeostatic balance of Earth's long-term carbon cycle and the equable state of Earth's climate are maintained by negative feedbacks between the levels of atmospheric CO2 and the chemical weathering rate of silicate rocks. Though clearly demonstrated by well-controlled laboratory dissolution experiments, the temperature dependence of silicate weathering rates, hypothesized to play a central role in these weathering feedbacks, has been diffic...
