The Basics of Climate Change Science - The Series
1. So is it "Global Warming" or "Climate Change?": A guide to some basic terms used by climate change scientists, including clarification of terms that scientists and the public use in different ways.
2. What is the Greenhouse Effect and What Does it Have to Do with Global Warming?: The Earth is kept warm by the natural greenhouse effect. This post describes the basic scientific principles and the history of their discovery, beginning with William Herschel in 1800.
3. So What are Greenhouse Gases and What are NOT Greenhouse Gases?: Most of the warming of the greenhouse effect is caused by a few gases that occur in very small amounts in the atmosphere. The strongest greenhouse gases are water vapor, CO2, methane, and ozone, with CO2 being the main driver of warming.
4. CO2 and Other Radiative Forcings of Global Warming: Impacts on the warming of the climate include forcings and feedbacks. This post explains the basic principles and the main drivers of global warming.
5. Carbon Dioxide (CO2): The Smoking Gun of Climate Change: CO2 is the main driver of global warming. This post introduces the relationship between CO2 and temperature, and sets the stage for future posts on why we know the CO2 we've added to the climate system is causing our current unprecedented spike in warming.
As noted, this is a continuing series so more posts will be linked as they are written. Feel free to bookmark this post and return periodically to catch any updates you may have missed.
For those interested in more detailed discussions of climate science, follow the links provided in the posts above. For those who like even more details, review the latest IPCC Assessment Report Number 5 (AR5), whose four volumes provide thousands of pages on the science. Start with the Synthesis Report to get a detailed overview, then move to the Physical Science Basis report to dig deeper on the science. The other two reports deal with Impacts, Adaptation, and Vulnerability and Mitigation of Climate Change, important for examining ways we can deal with the unequivocal science.
