Answer correctly and read the questions corretly, this is all one quesiton if done correclty and organized I will write a very nice review about you! Answer in 20 mintues 

Question: How does life contribute to the stability of the environment and especially through the sequestering of Carbon. Question: How does the weathering of silicate rocks on Earth's surface contribute to removing CO2 from the atmosphere? Explain how the silicate weathering feedback prevents the Earth from going into a runaway greenhouse and/or runaway ice-house scenario. But still, CO2 in the atmosphere is increasing. Questions: What is the current level (in ppmv - parts per million by volume) of CO2 in the atmosphere? What is the current rate of increase (in ppmv/year) of CO2 in the atmosphere? What is the increase (until presently) in global average temperature since pre-industrial times that is being correlated with the increase in CO₂ levels? An opinion: In your opinion (and you can't get your own opinion wrong), will we be able to stabilize our levels of atmospheric CO2 and other greenouse gases in the atmosphere in order to hold global warming to the Paris Accord's goal of 1.5C over pre-industrial levels?

Gaia: Carbon Regulation Silicate Weathering 2(CO₂) + 3(H₂O) + CaSiO3 = Ca²++2(HCO3)+H SIO CO₂ outgassing Continental plate CO₂ and H₂O forms carbonic acid Rising magma Accretionary wedge:. sediments derived from land/shelf Melting of carbonate rock Ca²++2(HCO3) CaCO₂ + CO₂ + H₂O Mid-ocean ridge Shelf: major area of limestone deposition Carbonate compensation depth Trench Oceanic plate (basalt) Some carbonate rocks are preserved by overlying sediments and subducted sks.to Carbon-silicate cycle. We now are beginning to recognize the Earth System comprising the physical and geological materials of the Earth and its place in the Solar System as well as the biology of planet, all working together produces a nearly stable environment and condition. In 1972, James Lovelock proposed the Gaia hypothesis which argued that life and biology are importantly involved in regulating the planet's surface environment through a stable Carbon Cycle.
