Deep-Ocean Mixing Helps Stabilize Earth’s Livability

TNRTB Archive - Retained for reference information

A team of international scientists has found additional evidence for fine-tuning in Earth’s global environment. Oceanic phytoplankton growth (and consequently chlorophyll concentration) maximizes at depths that receive both adequate light from above and sufficient flux of nutrients from below. The location of the chlorophyll concentrations significantly influences how much carbon is sequestered to the ocean interior and, therefore, also affects the amount of greenhouse gases in the atmosphere. Simulations reveal that global warming reduces deep-ocean mixing, which means the chlorophyll maximum will vary widely and could destabilize Earth’s global climate. The complexity of the global environment, and the many ways it could destabilize, testifies of a supernatural Designer maintaining a suitable environment for life to exist (“…in him all things hold together.” Colossians 1:17).
