Climate Time Machine - Climate Change: Vital Signs of the Planet
The ocean has absorbed 90% of human-induced global warming since 1955, causing the water's internal heat to rise. As a result, this change is contributing to polar ice loss, global sea level rise, extreme weather, large-scale coral bleaching events, and other far-reaching consequences.
Climate Change: Vital Signs of the Planet
Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.

Milankovitch Cycles and Their Role in Earth's Climate Small cyclical variations in the shape of Earth's orbit, its wobble and the angle its axis is tilted play key roles in influencing Earth's climate over timespans of tens of thousands to hundreds of thousands of years.
Orbital Cycles – Climate Change: Vital Signs of the Planet
NASA's new Orbiting Carbon Observatory-2 space satellite will probe the carbon cycle like never before, telling us where the carbon is going and giving us clues as to where we will end up.
Carbon Dioxide - Climate Change: Vital Signs of the Planet
Carbon dioxide (CO 2) is an important heat-trapping gas, also known as a greenhouse gas, that comes from the extraction and burning of fossil fuels (such as coal, oil, and natural gas), from wildfires, and natural processes like volcanic eruptions.The first graph shows atmospheric CO 2 levels measured by NOAA at Mauna Loa Observatory, Hawaii, since 1958.

2009年8月27日 · In 1864, Croll published a theory of the role Earth’s orbit might play in causing climate change, which has since been called the "Astronomical Theory of Climate Change”. He focused on the eccentricity of Earth’s orbit (how much the orbit varies from a perfect circle) and its precession (how much the planet ‘wobbles’ around its ...
