Our "environment" refers to different aspects of the environments humans interact with or influence: + Natural Environment: Includes all biological and physical elements naturally present on Earth—such as plants, animals, weather, geology, and natural landscapes. + Built Environment: Encompasses all human-made spaces and infrastructure where people live, work, and interact—like cities, buildings, roads, and other constructions. + Social Environment: Involves the cultural, economic, and social frameworks that shape individual and community behaviors, relationships, and dynamics—this includes laws, social norms, and institutions. + Space Environment: Refers to the extraterrestrial environment outside of Earth's atmosphere, important for space exploration and understanding cosmic phenomena. While these categories cover a broad spectrum of "environments," it's important to recognize that they are interconnected and can influence each other. |  | |

Can we limit global warming to 1.5 degrees? | Tectonic Plate MovementThe history of the Earth from its formation to present day, covering major events throughout its 4-billion-year history. Estimates of average temperature, atmospheric composition, and day length are given. |
Notion on Size: Cosmic EyeThis is the original landscape-format version of the short movie Cosmic Eye, designed by astrophysicist Danail Obreschkow. The movie zooms through all well-known scales of the universe from minuscule elementary particles out to the gigantic cosmic web. Cosmic Eye takes these historical visualisations to the state-of-the-art using real photographs obtained with modern detectors, telescopes, and microscopes. Other views are renderings of modern computer models. Vector-based blending techniques are used to create a seamless zoom. | Timelapse of the Entire UniverseOn a cosmic time scale, human history is as brief as the blink of an eye. By compressing all 13.8 billion years of time (Big Bang Model) into a 10 minute scale, the video shows just how young we truly are, and just how ancient and vast our universe is. Starting with the big bang and culminating in the appearance of homo sapiens, this experience follows the unfolding of time at 22 million years per second, adhering closely to current scientific understanding. |
History and Future of the Solar SystemWatch the Solar System unfold! | Layers of the AtmosphereEarth is surrounded by its atmosphere, which is the body of air or gases that protects the planet and enables life. Most of our atmosphere is located close to Earth's surface, where it is most dense. It has five distinct layers. |
Atmospheric CO2
Keeling Curve Monthly CO2.Earth is designed to simplify the process of monitoring critical global changes in real-time, allowing us to stay informed. CO2.Earth covers Atmospheric CO2 levels, global temperature trends, GHG emissions data, or Ocean acidification (pH). CO2.Earth is a citizen-led initiative eliminates the need to navigate various sources across the internet to obtain current and comprehensive information about our planet's status. CO2.Earth consolidates this data in user-friendly formats. Serving as a global online learning platform, it allows non-specialists to explore and discover valuable insights into our planet. At its core, CO2.Earth is a 'track and learn' website with a clear mission – to empower the global public to connect with planetary-level changes. The goal is to enable individuals to grasp what actions are necessary to stabilize CO2 concentrations in the atmosphere and address interconnected Earth system challenges. CO2.Earth encourages citizens to actively engage with the planet that has been our species' home in the vast cosmos.

This visualization captures sea surface temperature anomalies around the world from 1982 to 2017, along with a corresponding time plot graph that represents average equatorial sea surface temperatures in the Pacific Ocean from about the International Date Line to the coast of South America. Highlighted in the timeline are the El Niño years in which sea surface temperature anomalies peaked: 1982-1983, 1997-1998, and 2015-2016. |
Global Mean Temperature Anomaly 1850-2022Earth's warming trends since record-keeping began in 1850. Global temperature change from 1850 to 2022 in 90 seconds. The "Global Warming Mean Temperature Anomaly" visualization of Berkeley Earth's 2022 climate change data incorporates machine learning to represent in greater detail small-scale temperature variations at the local level, enabling governments to make better decisions about how to adapt to — and mitigate — climate change impacts. The "Global Warming by Country and Region 1850-2020" visualization, in the style of a switchboard, depicts global warming by country and region from 1850 to 2020. The blue circles show varying degrees of cooling anomalies of up to -3.0 C while the warm-coloured circles show the warming spikes of up to +3.0 C. For more information: Visit http://berkeleyearth.org/ | The Ozone Hole: Closing the GapIn the 1980s, scientists began to realize that ozone-depleting chemicals, such as chlorofluorocarbon (CFCs), were creating a thin spot—a hole—in the ozone layer over Antarctica. Through an international effort to decrease the use of CFCs, the ozone layer is starting to mend, and scientists believe it should mostly recover by the middle of the 21st century. This series of satellite images shows the ozone hole on the day of its maximum depth from 1979 through 2018. |
Carbon Dioxide and Global Temperature VisualizationThere has been a close correlation between changes in global temperature and the rise of carbon dioxide in the atmosphere during the last 170 years. An animated history of temperature vs. carbon dioxide. | Sea Level Rise and Fall Simulation - WorldThis is a video that simulates the rise and fall of the sea level. |
Animation of Antarctic sea ice coverage 1978-2023The annual cycle of the Southern Ocean freezing and melting is like a heartbeat for Earth. This animation shows Antarctic sea ice coverage pulsing between winter and summer over the 45 years since satellite records began in 1978. | Animation of Arctic sea ice coverage 1979-2022Satellites have provided a reliable tool for continuously monitoring changes in the Arctic ice since 1979. Every summer, the Arctic ice cap melts to what scientists call its "minimum" before colder weather begins to make ice cover increase. This visualization shows the expanse of the annual minimum Arctic sea ice for each year from 1979 through 2022, with a graph overlay. In 2022, Arctic minimum sea ice coverage tied for 10th-lowest on record, extending a long-term downward trend. |
