The Sun is becoming more luminous with time and will eventually overheat the biosphere. However, life cools the Earth by amplifying the rate of silicate rock weathering and maintaining a low level of atmospheric CO2. Recent studies indicate a much stronger biotic weathering effect than in models used to estimate the life span of the biosphere. Here we show that the resulting feedback lengthens the survival of complex life by delaying the loss of CO2 from the atmosphere. The weathering biota can… 
Biogenic Enhancement of Weathering and the Stability of the Ecosphere
TLDR
It can be shown that the biosphere is resilient to random perturbation of the global carbon cycle for the next 0.5-1.0 Gyr, which leads to an extension of the life span of theBiosphere by 0.7 Gyr compared to previous studies underestimating the effect of biogenic enhancement of weathering.
Causes and timing of future biosphere extinction
We present a minimal model for the global carbon cycle of the Earth containing the reservoirs mantle, ocean floor, continental crust, biosphere, and the kerogen, as well as the aggregated reservoir

Surface life has been argued to be crucial in keeping a planet habitable in the long term. Biologically enhanced weathering compensates for increasing solar luminosity, and temperature‐dependent
Causes and timing of future biosphere extinctions
Abstract. We present a minimal model for the global carbon cycle of the Earth containing the reservoirs mantle, ocean floor, continental crust, biosphere, and the kerogen, as well as the combined
Atmospheric pressure as a natural climate regulator for a terrestrial planet with a biosphere
TLDR
A simple model including the reduction of atmospheric pressure suggests that the life span of the biosphere can be extended at least 2.3 Ga into the future, more than doubling previous estimates and has important implications for seeking extraterrestrial life in the Universe.
Biogeosciences Causes and timing of future biosphere extinctions
We present a minimal model for the global carbon cycle of the Earth containing the reservoirs mantle, ocean floor, continental crust, biosphere, and the kerogen, as well as the combined ocean and
The end of life on Earth is not the end of the world: converging to an estimate of life span of the biosphere?
Abstract Environmental conditions have changed in the past of our planet but were not hostile enough to extinguish life. In the future, an aged Earth and a more luminous Sun may lead to harsh or even
Cambrian explosion triggered by geosphere‐biosphere feedbacks
A new hypothesis for the cause of the Cambrian explosion is presented. For that the evolution of the planet Earth is described by the co‐evolution of the geosphere‐biosphere system. Here we specify

Life span of the biosphere
There has been life on Earth for at least 3,500 Myr but the assumption that a comparable future lies ahead may not be justified. Main sequence stars appear to increase their burning rate as they age.

A hybrid model of the CO2 geochemical cycle and its application to large impact events.
TLDR
It appears unlikely, however, that an impact of a large asteroid or comet could create a "Strangelove ocean," in which surface waters remained corrosive to calcium carbonate for thousands or tens of thousands of years.
