About This Collection

What is climate change? A definition from the Department of Ecology of Washington State reads: Climate includes patterns of temperature, precipitation, humidity, wind and seasons. It affects more than just a change in the weather and refers to seasonal changes over a long period of time. These climate patterns play a fundamental role in shaping natural ecosystems, and the human economies and cultures that depend on them.

It may be used inter-changably with global warming as they’re closely related. Global warming causes climates to change. Here is NASA discussion on the two terms, What's In A Name?

We recommend you listen and learn which is the best advice we can give to begin to understand the challenges before us.

Projected U.S. Temperature Changes by 2100 from NASA

The continental U.S. could face an 8-degree Fahrenheit temperature increase by the end of the 21st century if carbon dioxide concentrations reach 800 parts per million. Current CO2 levels stand at 400 ppm and are rising faster than at any time in Earth's history.

These projections, from the draft National Climate Assessment, are vividly illustrated through computer model visualizations. Allison Leidner, a NASA scientist, emphasizes that these visualizations effectively communicate the dramatic potential changes to the nation's climate, including future temperature and precipitation scenarios.
