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 discusses how the presence of different groups around carbon can lead to enantiomers, using alanine as an example of L- and D- formations, emphasizing the predominance of L amino acids in protein synthesis. Chirality's importance is highlighted, noting that a protein's functionality depends on its shape.

(The geological interval from 66 million years ago to now is called the Cenozoic Era and consists of 3 periods: the Paleogene until 23 MYA, the Neogene until 2.6 MYA, and the Quaternary.) A group, the Cenozoic Carbon Dioxide Proxy Integration Project (CenCO2PIP) Consortium, reviewed and reevaluated all "proxy" measurements used to determine past cli…

Aliphatic hydrocarbons include saturated compounds like methane and unsaturated types like ethylene. Aromatic hydrocarbons are based on benzene rings and occur in biological molecules, including amino acids, cholesterol, and hormones. Beta-carotene is highlighted as a hydrocarbon containing both aliphatic and aromatic components.

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

This is a positive feedback because much more solar energy is absorbed by the water than by the pre-existing ice, and the temperature increase is amplified.
