Climate Science Presentation

As a group, my Australia maymester class and I meet once a week with Dr. Kris to prepare for our journey and discuss climate change. Last class, Dr. Kris taught us climate science through a PowerPoint. 

The most interesting point Dr. Kris mentioned was the difference between Greenhouse Effect, Global Warming, and Global Climate Change. It is important for us to use accurate terminology when reporting to a lay audience. If the reporter is not educated on distinguishing which term to use, the audience will not listen. 

Greenhouse Effect: Well-established theory; no debate; without it, life on Earth is not possible; not synonyms with--

Global Warming: Accurate; but only describes one possible outcome

Global Climate Change: Most accurate; range of potential impacts; "climate disruption" 

These terms are not easily communicated through traditional journalism. While in Australia, it is our job to improve our reporting by understanding the scientific terminology.

Moreover, climate change will encompass ALL other environmental issues (water, agriculture, insurance, air quality, etc.) Oceans have absorbed 90% of increased heat (IPCC p. 8) and 30% of emitted carbon dioxide (CO2) (resulting in acidification- p.11). Absorbing more C02 will help slow down global climate change. Cooler water can absorb more CO2 than warmer water.

Global ocean will continue to warm-- heat will penetrate to the deeper ocean and affect ocean circulation (pg. 24). As the ocean temperatures rise, the oceans will absorb less CO2... resulting in more global warming. CO2 is one of the primary greenhouse gas emissions.
