Why Milankovitch (Orbital) Cycles Can't Explain Earth's Current …
Feb 27, 2020 · Milankovitch cycles include the shape of Earth’s orbit (its eccentricity), the angle that Earth’s axis is tilted with respect to Earth’s orbital plane (its obliquity), and the direction that Earth’s spin axis is pointed (its precession).
Changes in Eccentricity - Climate Change: Vital Signs of the Planet
Travel through Earth's recent climate history and see how increasing carbon dioxide, global temperature and sea ice have changed over time.
Solar variability and terrestrial climate
Jan 21, 2013 · A new report issued by the National Research Council (NRC), "The Effects of Solar Variability on Earth's Climate," lays out some of the surprisingly complex ways that solar activity can make itself felt on our planet.

Launching this spring, the two small satellites of NASA’s PREFIRE mission will fill in missing data from Earth’s polar regions.
What Is Climate Change? | Facts - Climate Change: Vital Signs of …
Changes observed in Earth’s climate since the mid-20th century are driven by human activities, particularly fossil fuel burning, which increases heat-trapping greenhouse gas levels in Earth’s atmosphere, raising Earth’s average surface temperature.
Global Temperature - Climate Change: Vital Signs of the Planet
Overall, Earth was about 2.45 degrees Fahrenheit (or about 1.36 degrees Celsius) warmer in 2023 than in the late 19th-century (1850-1900) preindustrial average. The 10 most recent years are the warmest on record.
Direct Observations Confirm That Humans Are Throwing Earth's …
Mar 25, 2021 · A NASA study has confirmed with direct evidence that human activities are changing Earth's energy budget, trapping much more energy from the Sun than is escaping back into space. Earth is on a budget – an energy budget. Our planet is constantly trying to balance the flow of energy in and out of Earth’s system.
The Atmosphere: Earth's Security Blanket – Climate Change: Vital …
Oct 2, 2019 · Our atmosphere seems tantalizingly close and yet mysteriously distant. The life-sustaining air we breathe envelops our planet like a pale-blue security blanket, clinging to us by the force of gravity. We see birds, planes, an ever-changing patchwork of clouds and, in some places, air pollution.
