Qualitative evidence of climate change exists as well. The current increase in atmospheric carbon dioxide has happened very quickly—in a matter of hundreds of years rather than thousands of years. As more and more of the world's population adopts a resource-intensive lifestyle the climate problem becomes worse.

When incoming energy from the sun is absorbed, Earth warms. When energy is released from Earth into space, the planet cools. Many factors, both natural and human, can cause changes in Earth’s energy balance, including changes in greenhouse gasses; variations in the sun’s energy reaching Earth; and changes in the reflectivity of Earth’s atmosphere and surface.

Scientists who study climate have noted a series of marked changes that have gradually become increasingly evident during the last sixty years. Global climate change is the term used to describe altered global weather patterns, including a worldwide increase in temperature, due largely to rising levels of atmospheric carbon dioxide.

It notes that fish have less efficient systems due to pressure loss in gills, while squids use separate pumps. Amphibians possess three-chambered hearts with some blood mixing, whereas lizards have a muscular septum to enhance separation.

For example, during the Mesozoic Era, the Age of Dinosaurs, the climate was much warmer and carbon dioxide was abundant in the atmosphere. However, throughout the Cenozoic Era (65 Million years ago to today), the climate has been gradually cooling. This section summarizes some of these major past climate changes and how scientists study past climate change.

Early work by Van Helmont, Priestley, Ingen-Housz, and Senebier laid foundational insights, while Blackman's studies distinguished light and dark reactions. Van Niel's emphasis on water's role in oxygen release and Ruben's isotope studies confirmed that the oxygen produced comes from water.

The pH level of the oceans is projected to decrease even more by the end of the century as CO 2 concentrations are expected to increase for the foreseeable future.

It reveals that breathing patterns significantly change when inhaling a 92% oxygen and 8% carbon dioxide mix, while pure air or 100% oxygen has minimal effects. The discussion highlights carbon dioxide's critical role in stimulating ventilation and the carotid body's sensitivity to low oxygen levels at high altitudes.

The density of the atmospheric mass is much greater close to the surface and decreases rapidly with increasing altitude.
