Over the past 40 million years, and particularly during the last 15 million years, the Earth's climate has undergone a significant transformation. The once warm and wet climate has given way to colder temperatures and greater regional variations in precipitation. This shift has resulted in a complex mosaic of diverse climate and vegetation types across the globe. Understanding the factors that have driven this cooling and diversification is crucial for unraveling the Earth's climatic history.
One perspective attributes these changes to the shifting positions of the Earth's continents and oceans. The Atlantic Ocean has expanded while the Pacific Ocean has contracted, and the ancient equatorial Tethys Sea that once spanned much of Eurasia has diminished to form the present-day Mediterranean Sea. Furthermore, the proportion of continents covered by shallow inland seas has gradually decreased, exposing vast land areas and creating climates less moderated by the temperature-stabilizing influence of oceans. Computer simulations demonstrate that alterations in continental arrangement and inland sea size can significantly impact global climate over extended geological timescales. However, these factors alone are less convincing as the sole explanations for the dramatic climatic changes observed over the past 40 million years.
Another hypothesis proposes a long-term decrease in atmospheric carbon dioxide concentrations, which would reduce the amount of heat trapped by the atmosphere, leading to "greenhouse cooling." The atmospheric carbon dioxide levels over million-year timescales are primarily regulated by two processes. Chemical weathering of continental rocks removes carbon dioxide from the atmosphere and transports it in dissolved chemical form to the ocean, where marine biota absorb it and deposit it in seafloor sediments. Tectonic activity eventually releases this trapped carbon dioxide, as the Earth's lithospheric plates transport the seafloor to ocean trenches, where subduction carries old crust and sediments towards the Earth's hot interior. At great depths, the sediments melt, liberating carbon dioxide, which escapes through volcanic islands above the buried crust and returns to the atmosphere, completing the cycle.
If seafloor spreading (and consequently subduction) rates were to decrease significantly, less carbon dioxide would be released into the atmosphere, resulting in a relative depletion of atmospheric carbon dioxide and a drop in temperatures. However, globally averaged seafloor spreading rates have shown little or no net change over the past 40 million years. While subduction and volcanism eventually return the carbon dioxide to the atmosphere, this process takes a considerable amount of time (tens to hundreds of millions of years) to complete.
Plateau uplift may also influence climate by enhancing chemical weathering of rocks, thereby reducing atmospheric carbon dioxide concentrations. Carbon dioxide reacts with rainwater and groundwater to form carbonic acid, which interacts with silicate minerals in rocks during weathering. The resulting bicarbonate ions are carried into the oceans, where marine organisms such as plankton and corals absorb them and eventually deposit them on the seafloor. The net effect is that chemical weathering removes carbon dioxide from the atmosphere and sequesters it at the bottom of the oceans.
Maureen Raymo suggests that the uplift of plateaus and mountain ranges has increased the rate of chemical erosion of continental rock on a global scale. Uplift can enhance chemical weathering through several mechanisms. Heavy monsoons that develop at the margins of plateaus bring particularly intense rainfall. In these regions, uplift-related faulting and folding also expose fresh rock to the weathering process. Moreover, the steeper slopes created by plateau uplift accelerate runoff, which removes erosion products and intensifies the chemical attack on the rock. Raymo proposes that long-term uplift in Tibet and other regions may have increased the rate at which carbon dioxide is removed from the atmosphere.
