Subject: Can tropical tectonic activity trigger ice ages?

>>Carbon dioxide in the atmosphere is a major driver of shifts in the Earth’s climate, as we know all too well in our currently warming world. But it also works the other way – in the past too little CO2 has been associated with triggering ice ages. Now a team of scientists has found a surprising new mechanism that could lead to a drop in CO2 and bring on ice ages: Tropical tectonic activity.

Although ice ages are clearly marked in the geological record, it’s still a bit murky as to what could cause such drastic shifts in climate. Some cooling events may be the result of disrupted ocean currents or even comet collisions, but the general consensus is that reduced CO2 in the atmosphere is the most reliable way to put Earth on ice.<<

>>Today, there is one major suture zone still sitting in the tropics: the islands of Indonesia. The team says this is one of the most active carbon sinks in the world at the moment, but unfortunately, the process is likely too slow to help offset our rising CO2 emissions.<<

I heard that it was also tectonic activity that breaks ice ages.

It can be both. In a time of ice ages, the loss of heat due to the sun’s reflection off ice keeps the world cool. Volcanic ash on the surface of the ice retains heat, melting the ice.

But overall, i have yet to see a consistent explanation for ice ages. Neither milankovitch cycles, co2 levels, nor volcanic activity seem to suffice on their own.
