And scientists have worried that a gush of meltwater from a
warming Arctic might
dramatically slow the AMOC for centuries or even kill it off.
This chemical weathering process is too
slow to damp out shorter - term fluctuations, and there are some complexities — glaciation can enhance the mechanical erosion that provides surface area for chemical weathering (some of which may be realized after a time delay — ie when the subsequent
warming occurs —
dramatically snow in a Snowball Earth scenario, where the frigid conditions essentially shut down all chemical weathering, allowing CO2 to build up to the point where it thaws the equatorial region, at which point runaway albedo feedback drives the Earth into a carbonic acid sauna, which ends via rapid carbonate rock formation), while lower sea level may increase the oxidation of organic C in sediments but also provide more land surface for erosion... etc..
Global
warming could be
dramatically slowed.
While greenhouse gas concentrations have increased
dramatically,
warming has
slowed dramatically.
We have the practical solutions at hand to
dramatically reduce our carbon emissions,
slow the pace of global
warming, and pass on a healthier, safer world to future generations.
Almost one third of all human emissions have taken place since 1998, but
warming has
slowed dramatically during that same time frame.
Just for one example, if it turns out that, between melt of sea ice and Greenland ice, the North Atlantic Current
slows or stops, we would expect to see fairly
dramatically colder weather in Europe for a while, even thought this condition could be directly linked to results produced by GW (though in the long term, the
warming would, presumably eventually overtake the cooling from change in ocean currents).
