See the Effects of Climate Change Across Earth

VideoFromSpace

Jun 12, 2017

Spaceborne instruments provide evidence the climate is changing, from vanishing sea ice and rising seas to changes in soil moisture and more. The European Space Agency’s Climate Change Initiative have compiled a decade worth of imagery and satellite data and it has been animated by graphics producer Planetary Visions.

This visualization illustrates Earth’s long-term warming trend, showing temperature changes from 1880 to 2015 as a rolling five-year average. Orange colors represent temperatures that are warmer than the 1951-80 baseline average, and blues represent temperatures cooler than the baseline.

2019 Was the Second Hottest Year on Record

NASA Climate Change

Jan 15, 2020

Earth’s average global surface temperature in 2019 ranked second warmest since 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA). The average global surface temperature in 2019 was 2 degrees Fahrenheit (1.1 degrees Celsius) warmer than the late 19th Century, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York. It was second only to those of 2016 and continued the planet’s long-term warming trend: the six warmest years on the instrumental record have been the six last years.

Will America Wake Up Before It Is Too Late?

Thom Hartmann Program

May 7, 2020

If America doesn’t wake up to how Donald Trump and the billionaires are doing to the country before it is too late, Trump might put The United States to sleep
From the fueling of right-wing extremist in our own country, to the economic depression looming over our economy and the mishandling of COVID-19, Americans need to wake up, and fast.

Seasonal changes in carbon dioxide

NASA Climate Change

May 16, 2017

Carbon dioxide is the most important greenhouse gas released to the atmosphere through human activities. It is also influenced by natural exchange with the land and ocean. This visualization provides a high-resolution, three-dimensional view of global atmospheric carbon dioxide concentrations from September 1, 2014 to August 31, 2015. The visualization was created using output from the GEOS modeling system, developed and maintained by scientists at NASA. The height of Earth’s atmosphere and topography have been vertically exaggerated and appear approximately 400 times higher than normal to show the complexity of the atmospheric flow. Measurements of carbon dioxide from NASA’s second Orbiting Carbon Observatory (OCO-2) spacecraft are incorporated into the model every 6 hours to update, or “correct,” the model results, called data assimilation.

As the visualization shows, carbon dioxide in the atmosphere can be mixed and transported by winds in the blink of an eye. For several decades, scientists have measured carbon dioxide at remote surface locations and occasionally from aircraft. The OCO-2 mission represents an important advance in the ability to observe atmospheric carbon dioxide. OCO-2 collects high-precision, total column measurements of carbon dioxide (from the sensor to Earth’s surface) during daylight conditions. While surface, aircraft, and satellite observations all provide valuable information about carbon dioxide, these measurements do not tell us the amount of carbon dioxide at specific heights throughout the atmosphere or how it is moving across countries and continents. Numerical modeling and data assimilation capabilities allow scientists to combine different types of measurements (e.g., carbon dioxide and wind measurements) from various sources (e.g., satellites, aircraft, and ground-based observation sites) to study how carbon dioxide behaves in the atmosphere and how mountains and weather patterns influence the flow of atmospheric carbon dioxide. Scientists can also use model results to understand and predict where carbon dioxide is being emitted and removed from the atmosphere and how much is from natural processes and human activities.

Carbon dioxide variations are largely controlled by fossil fuel emissions and seasonal fluxes of carbon between the atmosphere and land biosphere. For example, dark red and orange shades represent regions where carbon dioxide concentrations are enhanced by carbon sources. During Northern Hemisphere fall and winter, when trees and plants begin to lose their leaves and decay, carbon dioxide is released in the atmosphere, mixing with emissions from human sources. This, combined with fewer trees and plants removing carbon dioxide from the atmosphere, allows concentrations to climb all winter, reaching a peak by early spring. During Northern Hemisphere spring and summer months, plants absorb a substantial amount of carbon dioxide through photosynthesis, thus removing it from the atmosphere and change the color to blue (low carbon dioxide concentrations). This three-dimensional view also shows the impact of fires in South America and Africa, which occur with a regular seasonal cycle. Carbon dioxide from fires can be transported over large distances, but the path is strongly influenced by large mountain ranges like the Andes. Near the top of the atmosphere, the blue color indicates air that last touched the Earth more than a year before. In this part of the atmosphere, called the stratosphere, carbon dioxide concentrations are lower because they haven’t been influenced by recent increases in emissions.

This version of the visualization was created specifically to support a series of papers in the journal Science and for submission to SIGGRAPH 2017’s Computer Animation Festival.

This visualization won Science magazine’s 2017 Data Stories contest in the “professional” category (see: http://www.sciencemag.org/projects/da…). Download the video: https://svs.gsfc.nasa.gov/4565.

On Thin Ice: Why Ice Loss Matters

NASA Climate Change

Mar 31, 2020

Over 90 percent of Earth’s ice mass is locked up in Greenland and Antarctica. As our greenhouse gas emissions warm the planet, those areas, along with glaciers worldwide, lose more ice, contributing to sea level rise. Watch the video to learn how many people are threatened by this phenomenon worldwide and how much global sea level is projected to rise by 2100.
