How Global Warming Works: Climate Change's Mechanism Explained

by Professor Michael Ranney, Dr. Daniel Reinholz, and Dr. Lloyd Goldwasser (with help from Professor Ronald Cohen)

You may have heard of global climate change, which is often called “global warming.” Whether or not people accept that humans are causing global warming, most folks have an opinion about it. But how much do regular people understand the science of climate change? If you were asked to explain how global warming works, could you? Take a moment to try to explain to yourself how virtually all climate scientists think the Earth is warming. What is the physical or chemical mechanism?

Don’t feel bad; if you’re anything like the people we’ve surveyed in our studies, you probably struggled to come up with an explanation. In fact, in one study, we asked almost 300 adults in the US––and not a single person could accurately explain the mechanism of global warming at a pretty basic level. This is consistent with larger surveys that have shown that people often lack knowledge about climate change. But how can we make informed decisions without understanding the issues we’re debating?

"Stephen Schneider explores what a world with 1,000 parts per million of CO 2 in its atmosphere might look like."

.... "Fairness must also be taken into account, given that some people would be at much greater risk than others: poor people in hot countries with little adaptive capacity, for instance, indigenous peoples and those exposed to hurricanes or wildfires, or living in low-lying areas. The elderly and children with asthma or other lung ailments would be particularly affected by urban air pollution or wildfire smoke plumes exacerbated by the extreme warming.

The economic outlook is no better. With warming of just 1–3 °C, projections show a mixture of benefit and loss. More than a few degrees of warming, however, and aggregate monetary impacts become negative virtually everywhere; and in a 1,000 p.p.m. scenario current literature suggests the outcomes would be almost universally negative and could amount to a substantial loss of gross domestic product. Millions of people at risk from flooding and

water supply problems would provide further economic challenges." ...
