Visualization of Earth’s Next 100 Years

Scientists use climate models to predict how Earth’s climate will change. Climate models are computer programs with mathematical equations. They are programmed to simulate past climate as accurately as possible. This gives scientists some confidence in a climate model’s ability to predict the future. Climate models predict that Earth’s average temperature will keep rising over […]

Detecting Forest Cover Change by High Resolution Space Imageries

Dr. Matthew Hansen at the University of Maryland, we’ve built the first detailed maps of the world’s forests, from 2000-2012, documenting and quantifying forest landscape changes such as fires, tornadoes, disease and logging. The most significant findings were that the overall rate of tropical deforestation is increasing, and global forests have experienced a net loss […]

Why is Antarctic sea ice growing?

October 31, 2013 | Climate Change, Environmental Issues | by aHaSaN

Recently NASA reported that this year’s maximum wintertime extent of Antarctic sea ice was the largest on record, even greater than the previous year’s record. This is understandably at odds with the public’s perception of how polar ice should respond to a warming climate, given the dramatic headlines of severe decline in Arctic summertime extent. […]

Its a Hard Choice: Nuclear over Coal ??

October 10, 2013 | Climate Change, Environmental Issues | by aHaSaN

Most of the world’s electrical power is generated by utilizing non-renewable energy resources such as coal or uranium. While each material has a long and productive history of powering electrical plants, they also provide environmental challenges that defy easy comparison. Only by examining the total lifetime risks of the coal and uranium used in energy […]

Which will Give the Signal Green: Coal or Nuclear ??

October 10, 2013 | Climate Change, Environmental Issues | by aHaSaN

Human-caused climate change and air pollution remain major global-scale problems and are both due mostly to fossil fuel burning. Mitigation efforts for both of these problems should be undertaken concurrently in order to maximize effectiveness. Such efforts can be accomplished largely with currently available low-carbon and carbon-free alternative energy sources like nuclear power and renewables, […]

Global Climate Change: Key Indicators

August 14, 2013 | Climate Change, Disaster Management | by aHaSaN

Carbon dioxide (CO2) is an important heat-trapping (greenhouse) gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions. The chart on the left shows the CO2 levels in the Earth’s atmosphere during the last three glacial cycles, as reconstructed from […]

Timing a Rise in Sea Level

August 14, 2013 | Climate Change, Disaster Management | by aHaSaN

Thirty-five years ago, a scientist named John H. Mercer issued a warning. By then it was already becoming clear that human emissions would warm the earth, and Dr. Mercer had begun thinking deeply about the consequences. His paper, in the journal Nature, was titled “West Antarctic Ice Sheet and CO2 Greenhouse Effect: A Threat of […]

How is climate change shaping the type of space exploration NASA does?

As global climate change becomes more evident, NASA’s satellite program for studying and monitoring our home planet becomes increasingly important. There are two key areas toward which NASA satellite measurements can contribute: 1.  Monitoring changes in the Earth’s climate.  Global climate change occurs slowly relative to weather and even to the change of seasons throughout […]
