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.

NASA | Ask a Climate Scientist: CO2 and Temperature by Dr. Hildebrand

Studies indicating historical CO2 levels lag behind temperature have merit, confirms Peter Hildebrand, Director of Earth Science at NASA's Goddard Space Flight Center. Responding to a question on Twitter, Hildebrand explained that in the pre-industrial age, temperature changes drove CO2 levels; a warmer climate caused the biosphere to emit more CO2.

However, in the post-industrial era, this dynamic has reversed. Now, increasing atmospheric CO2 is leading to higher temperatures, indicating a fundamental shift in the physical-biological processes. For more information, visit Ask A Climate Scientist.
